Description

Technical Field

[0001] The utility model relates to the technical field of exhaust structures, in particular to an exhaust device and a heating device. Background Art

[0002] At present, for bathroom heater products in related technologies, for products without swing blades at the air outlet, it is impossible to adjust the flow rate, flow direction, etc. of the air flow according to actual needs, which reduces the user's blowing experience. Utility Model Content

[0003] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the utility model provides an exhaust device.

[0005] A second aspect of the embodiments of the present utility model provides a heating device.

[0006] In view of this, according to the first aspect of an embodiment of the utility model, an exhaust device is provided, the exhaust device comprising: a body, the body being provided with an air outlet; a movable part, movably arranged on the body, a part of the movable part and a part of the body being combined to form an exhaust channel, the exhaust channel being connected to the air outlet, and the movable part being able to move relative to the body to change the flow cross-sectional area of ​​the exhaust channel.

[0007] The exhaust device provided in the embodiment of the utility model comprises a body and a movable part. Specifically, the body is provided with an air outlet.

[0008] Optionally, the machine body is further provided with a fan or a blower. Specifically, the fan or the blower can generate airflow when started, and the airflow flows out from the air outlet.

[0009] Optionally, the heating device includes a heating element, which is arranged in the body and located on the flow path of the airflow, that is, the airflow flowing out of the air outlet is a hot airflow, thereby heating the indoor space, increasing the indoor temperature, and thus improving the comfort of the user. Optionally, the heating device is an indoor electric heating device, such as a bathroom heater.

[0010] A part of the movable part and a part of the body are enclosed to form an exhaust passage, and the exhaust passage is communicated with the air outlet, that is, the airflow flowing out of the air outlet can be discharged through the exhaust passage.

[0011] The movable part can move relative to the body to change the flow cross-sectional area of ​​the exhaust passage, that is, the movable part can change the size of the distance between the movable part and the body during the movement relative to the body. It can be understood that when the flow cross-sectional area of ​​the exhaust passage changes, the pressure of the airflow flowing out of the exhaust passage will also change, that is, the wind pressure changes, thereby changing the airflow velocity. In other words, by controlling the movement of the movable part relative to the body, the velocity of the airflow flowing out of the exhaust passage can be adjusted. Moreover, due to the change in the airflow velocity, the direction of the airflow flowing out of the exhaust passage will also change to a certain extent, thereby achieving the adjustment of the wind direction.

[0012] By controlling the movement of the movable parts relative to the body, the direction and flow rate of the airflow from the exhaust device can be adjusted, so that the movement position of the movable parts can be adjusted according to the actual needs of the user, thereby providing the user with a more comfortable airflow, enriching the use functions of the exhaust device, and improving the user experience.

[0013] Moreover, compared with the related art in which no swing blades are provided at the air outlet, it is also possible to adjust the wind direction and wind speed, thereby improving the applicability of the exhaust device.

[0014] In addition, the exhaust device provided by the above technical solution of the utility model also has the following additional technical features:

[0015] In some technical solutions, optionally, the movable part includes a first air guiding surface, and the first air guiding surface forms a part of the channel wall of the exhaust channel; wherein, at least a part of the first air guiding surface is constructed as an arc surface or an inclined surface.

[0016] In this technical solution, it is defined that the movable part includes a first wind guiding surface. Specifically, the first wind guiding surface constitutes a part of the channel wall of the exhaust channel.

[0017] At least part of the first wind guide surface is configured as an arc surface. Alternatively, at least part of the first wind guide surface is configured as an inclined surface. The configuration can be made according to actual needs.

[0018] By setting at least a portion of the first air guide surface as an arc-shaped surface or a slope, that is, at least a portion of the exhaust channel extends obliquely, so that when the movable part moves relative to the body to change the size of the flow cross-sectional area of ​​the exhaust channel, and then by changing the wind pressure of the outlet air flow to achieve wind speed regulation, the first air guide surface can guide the airflow flowing out of the exhaust channel. At the same time, under the joint action of the wind speed difference, the flow direction of the outlet air flow can be further adjusted, which is beneficial to increase the flow range of the outlet air flow, achieve rapid regulation of indoor temperature, and improve user comfort.

[0019] In some technical solutions, optionally, when at least a portion of the first air guiding surface is configured as an arc-shaped surface, the center of the arc-shaped surface is located on a side of the arc-shaped surface facing away from the machine body.

[0020] In this technical solution, at least part of the first air guide surface is defined as a curved surface. Specifically, the center of the curved surface is located on the side of the curved surface away from the body. That is to say, a part of the movable part protrudes toward the side where the body is located to form a curved surface, so that the outlet end of the formed exhaust channel extends outwardly, which is beneficial to increase the air outlet range of the exhaust device, thereby realizing rapid adjustment of the indoor temperature and improving user comfort and experience.

[0021] In some technical solutions, optionally, when at least a portion of the first wind guiding surface is configured as an inclined surface, an end of the inclined surface facing away from the body extends obliquely in a direction away from the center of the movable part.

[0022] In this technical solution, at least a portion of the first air guide surface is defined as an inclined surface. Specifically, one end of the inclined surface that is away from the body extends obliquely in a direction away from the center of the movable part, so that the outlet end of the exhaust passage formed extends obliquely outward, which is beneficial to increase the air outlet range of the exhaust device, thereby achieving rapid adjustment of the indoor temperature and improving user comfort and experience.

[0023] In some technical solutions, optionally, the machine body is further provided with a second air guide surface, and the second air guide surface and the first air guide surface are combined to form an exhaust passage; wherein the shape of the second air guide surface is adapted to the shape of the first air guide surface.

[0024] In this technical solution, it is defined that the machine body is further provided with a second wind guide surface. Specifically, the second wind guide surface and the wind guide surface are combined to form an exhaust passage.

[0025] The shape of the second wind guide surface is adapted to the shape of the first wind guide surface. Specifically, when the first wind guide surface is an inclined surface, the second wind guide surface is also an inclined surface, and the inclination direction of the second wind guide surface is consistent with the inclination direction of the first wind guide surface. When the first wind guide surface is an arcuate surface, the second wind guide surface is also an arcuate surface, and the centers of the two arcuate surfaces are located on the same side.

[0026] Since the shape of the second air guide surface is adapted to the shape of the first air guide surface, the flow direction of the outlet air flow can be further limited, and the air outlet range of the exhaust device can be increased, which is conducive to achieving rapid adjustment of indoor temperature and improving comfort and experience.

[0027] In some technical schemes, optionally, the machine body is further provided with a flow opening, the movable part is located in the flow opening, and can move between a first position and a second position relative to the flow opening; wherein, when the movable part is in the first position, there is a gap between the outer edge of the movable part and the outer edge of the machine body, and the exhaust passage is connected with the flow opening through the gap; when the movable part is in the second position, the outer edge of the movable part contacts the outer edge of the machine body, and the exhaust passage is cut off from the flow opening.

[0028] In this technical solution, it is defined that the machine body is further provided with a flow opening, and it can be understood that the flow opening is communicated with the outside.

[0029] The movable part is located in the flow opening, and the movable part can move between a first position and a second position in the flow opening. Specifically, when the movable part moves to the first position, a part of the movable part extends through the flow opening, and there is a gap between the outer edge of the movable part and the outer edge of the body, and the exhaust passage is connected to the flow opening through the gap. That is to say, after the airflow from the air outlet enters the exhaust passage, it flows into the room through the gap and the flow opening in sequence. Optionally, there can be multiple first positions, and the multiple first positions correspond to different flow cross-sectional areas of the exhaust passage, so as to achieve the adjustment of multiple gears of wind direction and wind speed.

[0030] When the movable part moves to the second position, a part of the movable part retracts into the flow opening, and the outer edge of the movable part contacts the outer edge of the body, so that the exhaust passage is closed and the exhaust device does not have the blowing function.

[0031] By controlling the movable part to move between the first position and the second position, the exhaust passage can be opened and closed, which is conducive to flexible control of various functions of the exhaust device and further enhances the user experience.

[0032] In some technical solutions, optionally, when the movable member is in the second position, the first appearance surface of the movable member is exposed at the flow opening and is flush with the second appearance surface of the body.

[0033] In this technical solution, when the movable part is in the second position, that is, when the exhaust passage is closed and the exhaust device does not have the blowing function, the first appearance surface of the movable part is flush with the second appearance surface of the body, thereby hiding the flow port and the exhaust passage in appearance, making the appearance of the exhaust device simple, which is conducive to improving the aesthetics of the exhaust device.

[0034] In some technical solutions, optionally, the exhaust device also includes a driving component, which is disposed on the body and connected to the movable part. The driving component can drive the movable part to move relative to the body to change the flow cross-sectional area of ​​the exhaust channel.

[0035] In this technical solution, it is defined that the exhaust device also includes a driving assembly. Specifically, the driving assembly is arranged on the machine body, and the driving assembly is connected to the movable part.

[0036] Specifically, under the drive of the driving component, the movable part moves relative to the body to change the flow cross-sectional area of ​​the exhaust channel. Even if no swing blades are set at the air outlet, the flow rate and direction of the air flow of the exhaust device can be adjusted. The movement position of the movable part can be adjusted according to the actual needs of the user, which is convenient for providing the user with a more comfortable airflow, enriching the use function of the exhaust device, and improving the user experience.

[0037] By setting up a driving component, it is convenient to control the movement direction and movement position of the movable parts, realize the adjustment of multiple wind speeds and multiple wind directions, and further improve the flexibility and comfort of the exhaust device in regulating indoor temperature.

[0038] It can be understood that by driving the movable part to move through the driving component, the movable part can have multiple movement positions, and the multiple movement positions correspond to multiple different flow cross-sectional areas of the exhaust channel, so as to achieve multiple gear adjustments of wind speed and wind direction, which is conducive to further improving the user experience.

[0039] In addition, the moving direction of the movable member can be controlled by the driving assembly, specifically, the movable member can be controlled to move downward to increase the flow cross-sectional area of ​​the exhaust passage, the movable member can be controlled to move upward to reduce the flow cross-sectional area of ​​the exhaust passage, or the exhaust passage can be closed. Specific settings can be made according to actual needs.

[0040] In some technical solutions, optionally, the body is also provided with a guide groove; the driving assembly includes a driving member and a transmission assembly, wherein the driving member is connected to the movable member through the transmission assembly, and a part of the transmission assembly is located in the guide groove and can move in the guide groove.

[0041] In this technical solution, it is defined that the driving component includes a driving member and a transmission component. Specifically, the driving member is connected to the transmission component, and the transmission component is connected to the movable member. That is to say, under the drive of the driving member, the transmission component can drive the movable member to move relative to the machine body to change the flow cross-sectional area of ​​the exhaust channel.

[0042] A portion of the transmission assembly is located in the guide groove and can move in the guide groove, thereby indirectly limiting the movement range of the movable part, thereby achieving adjustment of the wind direction and wind speed of the exhaust device within a certain range, thereby improving the comfort and flexibility of the exhaust device in regulating indoor temperature.

[0043] In some technical solutions, optionally, at least a portion of the guide groove extends along the height direction of the machine body.

[0044] In this technical solution, since a part of the transmission assembly is located in the guide groove and can move in the guide groove, the movement range of the movable part is indirectly limited. At least a part of the guide groove extends along the height direction of the machine body, that is, the movement direction of the movable part relative to the machine body is limited to the height direction, that is, the movable part moves up and down relative to the machine body to change the flow cross-sectional area of ​​the exhaust channel, realize the adjustment of the wind direction and wind speed of the exhaust device within a certain range, and improve the comfort and flexibility of the exhaust device in adjusting the indoor temperature.

[0045] In addition, since the moving direction of the movable part is the height direction, it can adjust the flow direction and flow rate of the outlet air flow while helping to reduce the space occupied by the exhaust device in the horizontal direction, thereby helping to reduce the volume of the exhaust device and further improve the applicability of the exhaust device.

[0046] In some technical schemes, optionally, the transmission assembly includes a transmission member, a gear set and a positioning member, wherein the transmission member is arranged on the machine body, the transmission member is provided with a transmission groove, the transmission groove is connected to the guide groove, the gear set is arranged on the transmission member and is connected to the driving member, one end of the positioning member passes through the transmission groove and the guide groove in sequence and is connected to the movable member, and the other end of the positioning member is located in the transmission groove.

[0047] In this technical solution, it is defined that the transmission assembly includes a transmission member, a gear set and a positioning member. Specifically, the gear set is connected to the driving member, and the gear set is arranged on the transmission member. That is to say, under the drive of the driving member, the gear set can drive the transmission member to rotate relative to the machine body.

[0048] A transmission groove is provided on the transmission member, and the transmission groove is connected with the guide groove. One end of the positioning member passes through the transmission groove and the guide groove respectively and is connected with the movable member, and the other end of the positioning member is located in the transmission groove, that is, the positioning member is located in the transmission groove and the guide groove at the same time.

[0049] Since the transmission member can rotate relative to the body, that is, the transmission groove can rotate relative to the body, and a part of the positioning member is located in the transmission groove, the positioning member can drive the movable member to move within the range limited by the guide groove under the action of the transmission groove, so as to change the flow cross-sectional area of ​​the exhaust channel and realize the adjustment of the flow rate and flow direction of the exhaust air flow of the exhaust device.

[0050] Optionally, there are multiple transmission grooves, which are arranged at intervals along the circumference of the movable member. The positioning members correspond to the transmission grooves one by one.

[0051] In some technical solutions, optionally, at least a portion of the transmission groove extends along the circumference of the movable part, and the transmission groove includes a first end and a second end opposite to each other, and along the height direction of the body, the first end and the second end have a height difference.

[0052] In this technical solution, it is defined that the transmission groove includes a first end and a second end, specifically, the first end and the second end are opposite to each other, and at least a part of the transmission groove extends along the circumference of the movable part.

[0053] Along the height direction of the machine body, the first end and the second end have a height difference. Specifically, along the height direction of the machine body, the first end is higher than the second end. Alternatively, along the height direction of the machine body, the second end is higher than the first end. The specific setting can be based on actual needs.

[0054] Since there is a height difference between the first end of the transmission groove and the second end of the transmission groove, when the transmission groove rotates relative to the machine body, the positioning member can have a height displacement in the guide groove, thereby driving the movable member to move along the height direction of the machine body to change the flow cross-sectional area of ​​the exhaust channel.

[0055] It can be understood that when the transmission groove rotates relative to the body, a part of the positioning member can move in the transmission groove. Since there is a height difference between the first end of the transmission groove and the second end of the transmission groove, and at least a part of the transmission groove extends along the circumference of the movable member, that is, at least a part of the transmission groove extends at an angle, part of the positioning member can generate a height displacement when moving in the transmission groove.

[0056] In some technical solutions, optionally, the movable part is further provided with a reinforcing rib, the reinforcing rib is provided with a connecting hole, and the positioning part passes through the transmission groove and the guide groove in sequence and then is connected to the connecting hole.

[0057] In this technical solution, by providing reinforcing ribs on the movable parts, the structural strength of the movable parts can be improved, and deformation of the movable parts during reciprocating motion can be prevented, which is beneficial to extending the service life of the exhaust device.

[0058] The reinforcing rib is provided with a connecting hole, and the positioning piece passes through the transmission groove and the guide groove in sequence and is connected with the connecting hole, thereby realizing a fixed connection between the positioning piece and the movable piece.

[0059] Optionally, one end of the positioning member is provided with an external thread, and the inner wall of the connecting hole is provided with an internal thread, that is, one end of the positioning member cooperates with the connecting hole thread, which is conducive to ensuring the connection strength between the positioning member and the movable member.

[0060] Optionally, there are multiple reinforcing ribs, and the multiple reinforcing ribs are arranged at intervals along the circumference of the movable part. The connecting holes correspond to the reinforcing ribs one by one. The positioning pieces correspond to the connecting holes one by one.

[0061] In some technical solutions, optionally, the gear set includes a gear and a rack, wherein the gear is connected to the driving member, the rack is provided on the transmission member and extends along the circumference of the movable member, and the rack is meshed with the gear.

[0062] In this technical solution, it is defined that the gear set includes a gear and a rack, and specifically, the gear is connected to the driving member. Optionally, the driving member includes a motor and an output shaft, the motor is connected to the output shaft, and the output shaft is connected to the gear, that is, under the drive of the motor, the output shaft drives the gear to rotate.

[0063] The rack is meshed with the gear, and the rack is arranged on the transmission member along the circumference of the movable member. That is to say, during the rotation of the gear, the transmission member is driven to rotate relative to the machine body through the rack.

[0064] Since the transmission member is provided with a transmission groove, one end of the positioning member passes through the transmission groove and the guide groove in sequence to connect with the movable member, and the other end of the positioning member is located in the transmission groove. Therefore, when the transmission member rotates, the transmission groove can provide power to the positioning member. At the same time, under the action of the guide groove, the positioning member drives the movable member to move along the guide groove to change the flow cross-sectional area of ​​the exhaust channel, thereby realizing the adjustment of the wind direction and wind speed of the exhaust device.

[0065] In some technical schemes, optionally, the machine body includes a main body and a fixed part, wherein the main body is provided with an air outlet, the fixed part is provided on the main body, the movable part is movably provided on the fixed part and is enclosed with the fixed part to form an exhaust channel, the fixed part is provided with an air outlet, and the air outlet is connected to the exhaust channel through the air outlet; at least a part of the air outlet is opposite to the air outlet.

[0068] At least part of the air inlet is opposite to the air outlet, so that all or most of the air flow from the air outlet can flow into the exhaust channel through the air inlet and be discharged through the exhaust channel, thereby improving the air outlet efficiency, facilitating rapid adjustment of the indoor temperature, and improving the user's comfort.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0089] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0090] Refer to the following Figures 1 to 8 To describe the exhaust device 100 and the heating device provided according to some embodiments of the present utility model.

[0091] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, an exhaust device 100 is proposed, which includes: a body 110, the body 110 is provided with an air outlet 111; a movable part 120, which is movably arranged on the body 110, a part of the movable part 120 and a part of the body 110 are enclosed to form an exhaust channel 130, the exhaust channel 130 is connected with the air outlet 111, and the movable part 120 can move relative to the body 110 to change the flow cross-sectional area of ​​the exhaust channel 130.

[0092] The exhaust device 100 provided in the embodiment of the utility model includes a body 110 and a movable part 120 . Specifically, the body 110 is provided with an air outlet 111 .

[0093] Optionally, the machine body 110 is further provided with a fan or a blower. Specifically, the fan or the blower can generate airflow when started, and the airflow flows out from the air outlet 111 .

[0094] Optionally, the heating device includes a heating element, which is arranged in the body 110 and located on the flow path of the airflow, that is, the airflow flowing out of the air outlet 111 is a hot airflow. Optionally, the heating device is an indoor electric heating device, such as a bathroom heater.

[0095] A portion of the movable member 120 and a portion of the body 110 are enclosed to form an exhaust passage 130 , and the exhaust passage 130 is connected to the air outlet 111 , that is, the airflow flowing out of the air outlet 111 can be discharged through the exhaust passage 130 .

[0096] The movable member 120 can move relative to the machine body 110 to change the flow cross-sectional area of ​​the exhaust passage 130, that is, the movable member 120 can change the size of the distance between the movable member 120 and the machine body 110 during the movement relative to the machine body 110. It can be understood that when the flow cross-sectional area of ​​the exhaust passage 130 changes, the pressure of the airflow flowing out of the exhaust passage 130 will also change, that is, the wind pressure changes, thereby changing the airflow velocity. In other words, by controlling the movement of the movable member 120 relative to the machine body 110, the velocity of the airflow flowing out of the exhaust passage 130 can be adjusted. Moreover, due to the change in the airflow velocity, the flow direction of the airflow flowing out of the exhaust passage 130 will also change to a certain extent, thereby achieving the adjustment of the wind direction.

[0097] By controlling the movement of the movable part 120 relative to the body 110, the flow direction and flow rate of the airflow of the exhaust device 100 can be adjusted, so that the movement position of the movable part 120 can be adjusted according to the actual needs of the user, so as to provide the user with a more comfortable airflow, enrich the use functions of the exhaust device 100, and enhance the user's use experience. Figure 1 The direction indicated by the dashed arrow is the airflow direction.

[0098] Moreover, compared with the related art in which no swing blades are provided at the air outlet, the wind direction and wind speed can be adjusted, thereby improving the applicability of the exhaust device 100.

[0099] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the movable member 120 includes a first wind guiding surface 121, and the first wind guiding surface 121 forms a portion of the channel wall of the exhaust channel 130; wherein, at least a portion of the first wind guiding surface 121 is constructed as an arc surface or an inclined surface.

[0100] In this embodiment, it is defined that the movable member 120 includes a first wind guiding surface 121 . Specifically, the first wind guiding surface 121 constitutes a portion of the channel wall of the exhaust channel 130 .

[0101] At least a portion of the first wind guide surface 121 is configured as an arc surface. Alternatively, at least a portion of the first wind guide surface 121 is configured as an inclined surface. The configuration can be made according to actual needs.

[0102] By setting at least a portion of the first air guide surface 121 as an arc-shaped surface or a slope, that is, at least a portion of the exhaust channel 130 extends obliquely, the movable part 120 moves relative to the body 110 to change the size of the flow cross-sectional area of ​​the exhaust channel 130, and then the wind pressure of the outlet air flow is changed to achieve wind speed regulation. At the same time, the first air guide surface 121 can guide the airflow flowing out of the exhaust channel 130. At the same time, under the joint action of the wind speed difference, the flow direction of the outlet air flow can be further adjusted, which is beneficial to increase the flow range of the outlet air flow, achieve rapid adjustment of the indoor temperature, and improve user comfort.

[0103] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, when at least a portion of the first wind guiding surface 121 is configured as an arc-shaped surface, the center of the arc-shaped surface is located on a side of the arc-shaped surface facing away from the body 110 .

[0104] In this embodiment, at least a portion of the first air guide surface 121 is defined as an arcuate surface. Specifically, the center of the arcuate surface is located on the side of the arcuate surface away from the body 110. That is to say, a portion of the movable part 120 protrudes toward the side where the body 110 is located to form an arcuate surface, so that the outlet end of the exhaust channel 130 formed is inclined and extends outward, which is beneficial to increase the air outlet range of the exhaust device 100, thereby realizing rapid adjustment of the indoor temperature and improving the user's comfort and experience.

[0105] In some embodiments, optionally, when at least a portion of the first wind guiding surface 121 is configured as an inclined surface, an end of the inclined surface facing away from the body 110 extends obliquely in a direction away from the center of the movable member 120 .

[0106] In this embodiment, at least a portion of the first air guide surface 121 is defined as an inclined surface. Specifically, the end of the inclined surface facing away from the body 110 extends obliquely in a direction away from the center of the movable part 120, so that the outlet end of the exhaust channel 130 formed extends obliquely outward, which is beneficial to increase the air outlet range of the exhaust device 100, thereby achieving rapid adjustment of the indoor temperature and improving the user's comfort and experience.

[0107] like Figure 1 As shown, in some embodiments, optionally, the body 110 is further provided with a second wind guide surface 112 , and the second wind guide surface 112 and the first wind guide surface 121 are enclosed to form an exhaust passage 130 ; wherein the shape of the second wind guide surface 112 is adapted to the first wind guide surface 121 .

[0108] In this embodiment, it is defined that the machine body 110 is further provided with a second wind guiding surface 112 . Specifically, the second wind guiding surface 112 and the wind guiding surface are combined to form an exhaust passage 130 .

[0109] The shape of the second wind guide surface 112 is adapted to the shape of the first wind guide surface 121. Specifically, when the first wind guide surface 121 is an inclined surface, the second wind guide surface 112 is also an inclined surface, and the inclination direction of the second wind guide surface 112 is consistent with the inclination direction of the first wind guide surface 121. When the first wind guide surface 121 is an arcuate surface, the second wind guide surface 112 is also an arcuate surface, and the centers of the two arcuate surfaces are located on the same side.

[0110] Since the shape of the second wind guide surface 112 is adapted to the shape of the first wind guide surface 121, the flow direction of the outlet airflow can be further limited, and the air outlet range of the exhaust device 100 is increased, which is conducive to achieving rapid adjustment of indoor temperature and improving comfort and experience.

[0111] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the body 110 is further provided with a flow port 113, the movable member 120 is located in the flow port 113, and can move between a first position and a second position relative to the flow port 113; wherein, when the movable member 120 is in the first position, there is a gap 140 between the outer edge of the movable member 120 and the outer edge of the body 110, and the exhaust passage 130 is connected with the flow port 113 through the gap 140; when the movable member 120 is in the second position, the outer edge of the movable member 120 contacts the outer edge of the body 110, and the exhaust passage 130 is cut off from the flow port 113.

[0112] In this embodiment, it is defined that the machine body 110 is further provided with a flow opening 113 . It can be understood that the flow opening 113 is in communication with the outside.

[0113] The movable member 120 is located in the flow port 113, and the movable member 120 can move between a first position and a second position in the flow port 113. Specifically, when the movable member 120 moves to the first position, a portion of the movable member 120 extends through the flow port 113, and a gap 140 is formed between the outer edge of the movable member 120 and the outer edge of the body 110, and the exhaust passage 130 is connected to the flow port 113 through the gap 140. Figure 1 As shown, that is, after the airflow from the air outlet 111 enters the exhaust channel 130, it flows into the room through the gap 140 and the flow port 113 in sequence. Optionally, there can be multiple first positions, and the multiple first positions correspond to different flow cross-sectional areas of the exhaust channel 130, so as to achieve the adjustment of multiple gears of wind direction and wind speed.

[0114] When the movable member 120 moves to the second position, a portion of the movable member 120 retracts into the flow opening 113, and the outer edge of the movable member 120 contacts the outer edge of the body 110, so that the exhaust passage 130 is closed, and the exhaust device 100 does not have a blowing function. Figure 2 shown.

[0115] By controlling the movable member 120 to move between the first position and the second position, the exhaust passage 130 can be opened and closed, which is conducive to flexible control of more than 100 functions of the exhaust device and further enhances the user experience.

[0116] like Figure 7 As shown, in some embodiments, optionally, when the movable member 120 is in the second position, the first appearance surface 122 of the movable member 120 is exposed at the flow opening 113 and is flush with the second appearance surface 114 of the body 110 .

[0117] In this embodiment, when the movable part 120 is in the second position, that is, when the exhaust passage 130 is closed and the exhaust device 100 does not have the blowing function, the first appearance surface 122 of the movable part 120 is flush with the second appearance surface 114 of the body 110, thereby hiding the flow port 113 and the exhaust passage 130 in appearance, making the appearance of the exhaust device 100 simple, which is beneficial to improving the aesthetics of the exhaust device 100.

[0118] like Figure 3 As shown, in some embodiments, optionally, the exhaust device 100 also includes a driving component 150, which is disposed on the body 110 and connected to the movable part 120. The driving component 150 can drive the movable part 120 to move relative to the body 110 to change the flow cross-sectional area of ​​the exhaust channel 130.

[0119] In this embodiment, it is defined that the exhaust device 100 further includes a driving assembly 150 . Specifically, the driving assembly 150 is disposed on the body 110 , and the driving assembly 150 is connected to the movable part 120 .

[0120] Specifically, driven by the driving component 150, the movable part 120 moves relative to the body 110 to change the flow cross-sectional area of ​​the exhaust channel 130. Even if no swing blades are provided at the air outlet 111, the flow rate and direction of the airflow of the exhaust device 100 can be adjusted. Therefore, the movement position of the movable part 120 can be adjusted according to the actual needs of the user, thereby providing the user with a more comfortable airflow, enriching the use function of the exhaust device 100, and improving the user's use experience.

[0121] By setting up the driving component 150, it is convenient to control the movement direction and movement position of the movable part 120, realize the adjustment of multiple wind speeds and multiple wind directions, and further improve the flexibility and comfort of the exhaust device 100 in adjusting the indoor temperature.

[0122] It can be understood that by driving the movable part 120 to move through the driving component 150, the movable part 120 can have multiple movement positions, and the multiple movement positions correspond to multiple different flow cross-sectional areas of the exhaust channel 130, so as to achieve multiple gear adjustments of wind speed and wind direction, which is conducive to further improving the user experience.

[0123] In addition, the moving direction of the movable member 120 can be controlled by the driving assembly 150, specifically, the movable member 120 can be controlled to move downward to increase the flow cross-sectional area of ​​the exhaust passage 130, the movable member 120 can be controlled to move upward to reduce the flow cross-sectional area of ​​the exhaust passage 130, or the exhaust passage 130 can be closed. The specific settings can be made according to actual needs.

[0124] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the body 110 is further provided with a guide groove 115; the driving assembly 150 includes a driving member 151 and a transmission assembly 152, wherein the driving member 151 is connected to the movable member 120 through the transmission assembly 152, and a part of the transmission assembly 152 is located in the guide groove 115 and can move in the guide groove 115.

[0125] In this embodiment, it is defined that the driving component 150 includes a driving member 151 and a transmission component 152. Specifically, the driving member 151 is connected to the transmission component 152, and the transmission component 152 is connected to the movable member 120. That is, under the drive of the driving member 151, the transmission component 152 can drive the movable member 120 to move relative to the body 110 to change the flow cross-sectional area of ​​the exhaust channel 130.

[0126] A portion of the transmission assembly 152 is located in the guide groove 115 and can move in the guide groove 115, thereby indirectly limiting the movement range of the movable part 120, thereby achieving adjustment of the wind direction and wind speed of the exhaust device 100 within a certain range, thereby improving the comfort and flexibility of the exhaust device 100 in regulating indoor temperature.

[0127] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, at least a portion of the guide groove 115 extends along the height direction of the body 110 .

[0128] In this embodiment, since a portion of the transmission assembly 152 is located in the guide groove 115 and can move in the guide groove 115, the movement range of the movable member 120 is indirectly limited. At least a portion of the guide groove 115 extends along the height direction of the body 110, that is, the movement direction of the movable member 120 relative to the body 110 is limited to the height direction, that is, the movable member 120 moves up and down relative to the body 110 to change the flow cross-sectional area of ​​the exhaust passage 130, so as to achieve the adjustment of the wind direction and wind speed of the exhaust device 100 within a certain range, and improve the comfort and flexibility of the exhaust device 100 in adjusting the indoor temperature.

[0129] In addition, since the movement direction of the movable part 120 is the height direction, it can help reduce the horizontal space occupied by the exhaust device 100 while adjusting the flow direction and flow rate of the exhaust airflow, which is beneficial to reducing the volume of the exhaust device 100 and further improving the applicability of the exhaust device 100.

[0130] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, optionally, the transmission assembly 152 includes a transmission member 153, a gear set 155 and a positioning member 156, wherein the transmission member 153 is disposed on the body 110, the transmission member 153 is provided with a transmission groove 154, the transmission groove 154 is connected to the guide groove 115, the gear set 155 is disposed on the transmission member 153 and is connected to the driving member 151, one end of the positioning member 156 passes through the transmission groove 154 and the guide groove 115 in sequence, and is connected to the movable member 120, and the other end of the positioning member 156 is located in the transmission groove 154.

[0131] In this embodiment, the transmission assembly 152 is defined to include a transmission member 153, a gear set 155 and a positioning member 156. Specifically, the gear set 155 is connected to the driving member 151, and the gear set 155 is arranged on the transmission member 153. That is, under the drive of the driving member 151, the gear set 155 can drive the transmission member 153 to rotate relative to the body 110.

[0132] A transmission groove 154 is provided on the transmission member 153, and the transmission groove 154 is connected to the guide groove 115. One end of the positioning member 156 passes through the transmission groove 154 and the guide groove 115 respectively and is connected to the movable member 120. The other end of the positioning member 156 is located in the transmission groove 154. That is, the positioning member 156 is located in the transmission groove 154 and the guide groove 115 at the same time.

[0133] Since the transmission member 153 can rotate relative to the body 110, that is, the transmission groove 154 can rotate relative to the body 110, and a part of the positioning member 156 is located in the transmission groove 154, under the action of the transmission groove 154, the positioning member 156 can drive the movable member 120 to move within the range defined by the guide groove 115, so as to change the flow cross-sectional area of ​​the exhaust channel 130, thereby realizing the adjustment of the flow rate and flow direction of the exhaust air flow of the exhaust device 100.

[0134] Optionally, there are multiple transmission grooves 154, and the multiple transmission grooves 154 are arranged at intervals along the circumference of the movable member 120. The positioning members 156 correspond to the transmission grooves 154 one by one.

[0135] like Figure 3 and Figure 6 As shown, in some embodiments, optionally, at least a portion of the transmission groove 154 extends along the circumference of the movable part 120, and the transmission groove 154 includes a first end 160 and a second end 170 opposite to each other, and along the height direction of the body 110, the first end 160 and the second end 170 have a height difference.

[0136] In this embodiment, the transmission groove 154 is defined to include a first end 160 and a second end 170 . Specifically, the first end 160 and the second end 170 are opposite to each other. At least a portion of the transmission groove 154 extends along the circumference of the movable member 120 .

[0137] The first end 160 and the second end 170 have a height difference along the height direction of the body 110. Specifically, along the height direction of the body 110, the first end 160 is higher than the second end 170. Alternatively, along the height direction of the body 110, the second end 170 is higher than the first end 160. The specific setting can be made according to actual needs.

[0138] Since there is a height difference between the first end 160 of the transmission groove 154 and the second end 170 of the transmission groove 154, when the transmission groove 154 rotates relative to the body 110, the positioning member 156 can have a height displacement in the guide groove 115, thereby driving the movable member 120 to move along the height direction of the body 110 to change the flow cross-sectional area of ​​the exhaust channel 130.

[0139] It can be understood that when the transmission groove 154 rotates relative to the body 110, a portion of the positioning member 156 can move in the transmission groove 154. Since there is a height difference between the first end 160 of the transmission groove 154 and the second end 170 of the transmission groove 154, and at least a portion of the transmission groove 154 extends along the circumference of the movable member 120, that is, at least a portion of the transmission groove 154 extends at an angle, part of the positioning member 156 can generate a height displacement when moving in the transmission groove 154.

[0140] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the movable member 120 is further provided with a reinforcing rib 123 , the reinforcing rib 123 is provided with a connecting hole 124 , and the positioning member 156 passes through the transmission groove 154 and the guide groove 115 in sequence and then is connected to the connecting hole 124 .

[0141] In this embodiment, the movable part 120 is provided with reinforcing ribs 123 , so that the structural strength of the movable part 120 can be improved, and the movable part 120 can be prevented from being deformed during the reciprocating motion, which is beneficial to prolonging the service life of the exhaust device 100 .

[0142] The reinforcing rib 123 is provided with a connecting hole 124 , and the positioning member 156 passes through the transmission groove 154 and the guide groove 115 in sequence and is connected to the connecting hole 124 , thereby achieving a fixed connection between the positioning member 156 and the movable member 120 .

[0143] Optionally, one end of the positioning member 156 is provided with an external thread, and the inner wall of the connecting hole 124 is provided with an internal thread, that is, one end of the positioning member 156 is threadedly matched with the connecting hole 124, which is conducive to ensuring the connection strength between the positioning member 156 and the movable member 120.

[0144] Optionally, there are multiple reinforcing ribs 123, and the multiple reinforcing ribs 123 are arranged at intervals along the circumference of the movable member 120. The connecting holes 124 correspond to the reinforcing ribs 123 one by one. The positioning members 156 correspond to the connecting holes 124 one by one.

[0145] like Figure 3 and Figure 4As shown, in some embodiments, optionally, the gear set 155 includes a gear 157 and a rack 158, wherein the gear 157 is connected to the driving member 151, the rack 158 is provided on the transmission member 153 and extends along the circumference of the movable member 120, and the rack 158 is meshed with the gear 157.

[0146] In this embodiment, it is defined that the gear set 155 includes a gear 157 and a rack 158. Specifically, the gear 157 is connected to the driving member 151. Optionally, the driving member 151 includes a motor and an output shaft, the motor is connected to the output shaft, and the output shaft is connected to the gear 157. That is, under the drive of the motor, the output shaft drives the gear 157 to rotate.

[0147] The rack 158 is meshed with the gear 157 , and the rack 158 is arranged on the transmission member 153 along the circumference of the movable member 120 . That is, during the rotation of the gear 157 , the transmission member 153 is driven to rotate relative to the body 110 by the rack 158 .

[0148] Since the transmission member 153 is provided with a transmission groove 154, one end of the positioning member 156 passes through the transmission groove 154 and the guide groove 115 in sequence to connect with the movable member 120, and the other end of the positioning member 156 is located in the transmission groove 154. Therefore, when the transmission member 153 rotates, the transmission groove 154 can provide power to the positioning member 156. At the same time, under the action of the guide groove 115, the positioning member 156 drives the movable member 120 to move along the guide groove 115, so as to change the flow cross-sectional area of ​​the exhaust channel 130, and realize the adjustment of the wind direction and wind speed of the exhaust device 100.

[0149] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, optionally, the body 110 includes a main body 116 and a fixing member 117, wherein the main body 116 is provided with an air outlet 111, the fixing member 117 is provided on the main body 116, the movable member 120 is movably provided on the fixing member 117, and is enclosed with the fixing member 117 to form an exhaust passage 130, the fixing member 117 is provided with an air outlet 118, and the air outlet 111 is connected to the exhaust passage 130 through the air outlet 118; at least a portion of the air outlet 118 is opposite to the air outlet 111.

[0150] In this embodiment, the machine body 110 is defined to include a main body 116 and a fixing member 117. Specifically, the main body 116 is provided with an air outlet 111, and the fixing member 117 is provided on the main body 116. The movable member 120 and the fixing member 117 are combined to form an exhaust passage 130, wherein the fixing member 117 is provided with a second air guide surface 112.

[0151] The fixing member 117 is provided with an air outlet 118 , that is, the airflow flowing out from the air outlet 111 enters the exhaust passage 130 through the air outlet 118 and is exhausted through the exhaust passage 130 .

[0152] At least part of the air vents 118 are opposite to the air outlet 111, so that all or most of the air flow from the air outlet 111 can flow into the exhaust passage 130 through the air vents 118 and be discharged through the exhaust passage 130, thereby improving the air outlet efficiency, facilitating rapid adjustment of the indoor temperature, and improving the user's comfort. Optionally, along the height direction of the body 110, at least part of the air vents 118 are opposite to the air outlet 111.

[0153] Optionally, the shape of the air port 118 is the same as that of the air outlet 111 , and the flow cross-sectional area of ​​the air port 118 is the same as that of the air outlet 111 , which is beneficial to further improve the air outlet efficiency of the exhaust device 100 .

[0154] Optionally, the machine body 110 further includes a panel assembly, and the panel assembly is provided with a flow opening 113 and a second appearance surface 114 .

[0155] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the body 110 is further provided with a first wire passing hole 119 ; the movable member 120 is further provided with a second wire passing hole 125 , and the first wire passing hole 119 is connected to the second wire passing hole 125 .

[0156] In this embodiment, it is defined that the body 110 is further provided with a first wire hole 119, and the movable member 120 is provided with a second wire hole 125, wherein the first wire hole 119 and the second wire hole 125 are connected. Specifically, the first wire hole 119 and the second wire hole 125 are used for wire passing, that is, the wires connecting the electrical components in the body 110 are routed through the first wire hole 119 and the second wire hole 125, so as to avoid the problem of the exhaust device 100 malfunctioning due to the disorderly distribution of the wires, or affecting the appearance of the product.

[0157] Optionally, the second wire passing hole 125 is provided on the reinforcing rib 123 .

[0158] According to the second aspect of the utility model, a heating device is provided, comprising the exhaust device 100 provided in any of the above embodiments, and thus having all the beneficial technical effects of the exhaust device 100, which will not be described in detail herein.

[0159] Optionally, the heating device includes an indoor electric heating device, such as a bathroom heater.

[0160] Specifically, the heating device includes a heating element, which is arranged in the body 110 and located on the flow path of the air flow. That is, the air flow flowing out from the air outlet 111 is a hot air flow, which heats the indoor space, increases the indoor temperature, and thus improves the user's comfort.

[0161] A portion of the movable member 120 and a portion of the body 110 are enclosed to form an exhaust passage 130 , and the exhaust passage 130 is connected to the air outlet 111 , that is, the hot air flow from the air outlet 111 can be discharged through the exhaust passage 130 .

[0162] The movable part 120 can move relative to the machine body 110 to change the flow cross-sectional area of ​​the exhaust passage 130, that is, the movable part 120 can change the size of the distance between the movable part 120 and the machine body 110 during the movement relative to the machine body 110. It can be understood that when the flow cross-sectional area of ​​the exhaust passage 130 changes, the pressure of the hot air flow when it flows out of the exhaust passage 130 will also change, that is, the wind pressure changes, thereby changing the flow rate of the hot air flow. In other words, by controlling the movement of the movable part 120 relative to the machine body 110, the flow rate of the hot air flow flowing out of the exhaust passage 130 can be adjusted. Moreover, due to the change in the flow rate of the hot air flow, the flow direction of the hot air flow flowing out of the exhaust passage 130 will also change to a certain extent, thereby achieving the adjustment of the wind direction.

[0163] By controlling the movement of the movable part 120 relative to the body 110, the flow direction and flow rate of the air flow of the exhaust device 100 can be adjusted, so that the movement position of the movable part 120 can be adjusted according to the actual needs of the user, thereby providing the user with a more comfortable hot air flow, enriching the use functions of the exhaust device 100, and improving the user experience.

[0164] Moreover, compared with the related art in which no swing blades are provided at the air outlet, the wind direction and wind speed can be adjusted, thereby improving the applicability of the exhaust device 100.

[0165] In a specific embodiment, Figure 8 As shown, the box assembly (main body 116) is installed inside the ceiling, the lifting assembly is fixedly installed at the box air outlet 111, and the panel assembly is sleeved on the outside of the lifting assembly.

[0166] like Figure 3 and Figure 4As shown, the lifting assembly includes a fixed air guide member (fixed member 117), a movable air guide member (movable member 120), a rotating guide sleeve (transmission member 153), a positioning pin (positioning member 156), a stepping motor (driving member 151), and a gear 157. The fixed air guide member is fixedly mounted on the box assembly (body 116), and is provided with an air hole (air outlet 118) having the same shape as the air outlet on the box assembly, and a fixed guide groove (guide groove 115) having the same number as the positioning pin.

[0167] The movable air guide member (movable member 120) is provided with positioning pin mounting holes (connecting holes 124) whose number is the same as the positioning pins. The rotating guide sleeve (transmission member 153) is sleeved on the fixed air guide member (fixed member 117) and can rotate relative to the fixed air guide member. The rotating guide sleeve is provided with a gear area (rack 158) that can mesh with the gear and movable guide grooves (transmission grooves 154) whose number is the same as the positioning pins. The positioning pins pass through the fixed guide grooves (guide grooves 115) and the rotating guide grooves (transmission grooves 154) at the same time and are fixedly installed on the positioning pin mounting holes (connecting holes 124), so that the movable air guide member can only reciprocate up and down relative to the fixed air guide member, and its reciprocating motion is controlled by the rotation of the rotating guide sleeve.

[0168] The stepper motor (driving member 151) is fixedly mounted on the fixed air guide member (fixed member 117), and the gear 157 is fixedly mounted on the motor shaft of the stepper motor and meshes with the gear area (rack 158) on the rotating guide sleeve (transmission member 153).

[0169] like Figure 2 As shown, driving the stepper motor (driving member 151) can drive the rotating guide sleeve (transmission member 153) to rotate, and after the movable air guide member (movable member 120) is lowered, the gap between the fixed air guide member (fixed member 117) and the movable air guide member (movable member 120) forms an air outlet channel (exhaust channel 130), and the wind generated by the box assembly enters the air outlet channel from the air hole (air outlet 118) and is blown out from the outlet at the end of the gap (gap 140).

[0170] Since the size of the air outlet passage changes, the wind speed will change due to the change in pressure when the wind is blown out from the outlet of the air outlet passage. Therefore, the wind speed can be adjusted by raising and lowering the movable air guide member (movable member 120).

[0171] The size of the outlet of the air outlet channel also changes, and the outlet is set to be oblique. When the outlet sizes are inconsistent, the angles of the wind blowing out from the outlet are different, and under the combined effect of the wind speed difference, the influence of the oblique surface on the wind direction is inconsistent, so that the wind direction can also be achieved by lifting the movable air guide member (movable member 120). When the gap 140 between the movable air guide member and the fixed air guide member is adjusted to the minimum, the outlet of the air outlet channel (exhaust channel 130) is closed.

[0172] like Figure 7 As shown, when the blowing function is not needed, the air outlet (flow port 113) is closed, and the air outlet is hidden in appearance, making the product appearance simple.
