Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and particularly to a blowing device. Background Art

[0002] Blowing devices such as bathroom heaters, warm air blowers, and dryers are usually provided with a strip-shaped air outlet and are equipped with a swing member extending along the opening length direction of the air outlet. The swing member rotates around a sweeping axis extending along the opening length direction of the air outlet to change the direction of the air flow bundle blown out of the air outlet. Traditional blowing devices can only adjust the direction and trajectory of the air flow bundle in a single dimension through the swing member, and the air outlet adjustment mode is single, which is not suitable for occasions where the object to be blown moves relative to the blowing device. Summary of the Invention

[0003] In view of this, the present invention provides a blowing device that can adjust the direction and trajectory of the air flow bundle in multiple dimensions to be suitable for occasions where the object to be blown moves.

[0004] The blowing device provided by the present invention includes a main body part, a blowing part, a control part, and a wind guiding part. The main body part is used to generate air flow. The blowing part is arranged on the main body part and has a cavity, and at least part of the cavity can form a wind storage cavity. The wind storage cavity can obtain the air flow generated by the main body part. The cavity penetrates through the blowing part and forms a blowing opening for the air flow generated by the main body part to be discharged and form an air flow bundle. The control part is movably arranged on the main body part and is used to change the distribution of the wind storage cavity in the first span direction of the main body part. The wind guiding part is arranged on the blowing part and is used to guide the air flow bundle.

[0005] Through the coordinated cooperation of the control part and the wind guiding part, the blowing device of the present invention can adjust the direction and / or trajectory of the air flow bundle in more dimensions, so as to be able to generate different blowing ranges. The control part expands the adjustable dimensions of the air flow bundle, so that the blowing device is suitable for the occasion where the object to be blown moves relative to itself, especially the occasion where the object to be blown moves relative to itself along the first span direction.

[0006] In one embodiment, the main body part has an air duct leading to the cavity. In a state where the air duct is communicated with at least part of the cavity, at least part of the cavity forms a wind storage cavity.

[0007] With such a setting, the air can flow concentratedly to the specified cavity under the guiding and constraining action of the air duct, so that these specified cavities can fully and sufficiently obtain these air flows, so that all these air flows become the air flow bundles, avoiding waste of air flows.

[0008] In one embodiment, the cavity at least includes a first cavity and a second cavity arranged along the first span direction. The first cavity and the second cavity penetrate through the blowing part to form a first blowing opening and a second blowing opening. The control part includes an on-off control part arranged in the air duct, and the on-off control part is used to switch the air duct to communicate with the first cavity and / or the second cavity.

[0009] With such a setting, the on-off control member can select at least one of the first chamber and the second chamber to communicate with the air duct and serve as the air storage chamber. Under different usage conditions, the blowing device can blow air through both the first air outlet and the second air outlet, or can blow air through the first air outlet or the second air outlet, so as to adjust the distribution and blowing range of the air flow in the first span direction.

[0010] In one embodiment, the air duct includes a main flow channel and a first branch channel. The main flow channel leads to the first chamber, and the first branch channel branches off from the main flow channel and leads to the second chamber. The main body portion further includes a wind driving portion for driving air to flow along the main flow channel;

[0011] When the on-off control member is in the first state, the first branch channel is blocked from the second chamber, and the main flow channel is unblocked from the first chamber; when the on-off control member is in the second state, the first branch channel is unblocked from the second chamber, and the main flow channel is blocked from the first chamber; when the on-off control member is in the third state, the first branch channel is unblocked from the second chamber, and the main flow channel is unblocked from the first chamber.

[0012] With such a setting, in the first state, the first chamber can receive the air flow of the air duct and blow air through the first air outlet; in the second state, the second chamber can receive the air flow of the air duct and blow air through the second air outlet; in the third state, both the first chamber and the second chamber can receive the air flow of the air duct and blow air through the first air outlet and the second air outlet.

[0013] In one embodiment, the blowing device further includes a ventilation portion provided on the main body portion and having a ventilation port. The air duct further includes a second branch channel that branches off from the main flow channel and leads to the ventilation port.

[0014] With such a setting, the blowing device is compatible with the ventilation function.

[0015] In one embodiment, the wind driving portion includes a centrifugal fan. The main flow channel surrounds the outer peripheral side of the centrifugal fan. The downstream end of the main flow channel penetrates through the first surface of the main body portion to communicate with the first chamber, and the first branch channel penetrates through the second surface of the main body portion to communicate with the second chamber.

[0016] With such a setting, the layout of the wind driving portion and the air duct is more compact and concentrated, which is beneficial to reducing the size of the main body portion and efficiently utilizing the internal space of the main body portion. The first chamber and the second chamber are respectively formed in two side regions of the main body portion, which is beneficial to expanding the maximum blowing range of the air flow blown by the blowing device.

[0017] In one embodiment, the blowing part is movably arranged on the main body part. The control part includes a pose adjusting part arranged on the main body part. The pose adjusting part is connected to the blowing part and is used to drive the blowing part to generate a configuration change at least in the first span direction, so that the air storage cavity generates a configuration change in the first span direction.

[0018] With such a setting, the pose adjusting part can drive the air outlet corresponding to the cavity communicated with the air duct to generate a configuration change in the first span direction. The shape and position of the air outlet will significantly affect the cross-section and position of the air outlet beam, so as to adjust the distribution and blowing range of the air outlet beam in the first span direction under different use conditions.

[0019] In one embodiment, the blowing part is rotatably arranged on the main body part and can rotate around a preset commutation axis. An inclined angle or a vertical angle is formed between the extending direction of the commutation axis and the first span direction.

[0020] With such a setting, it is ensured that the shape and position of the air outlet can generate changes in the first span direction, so as to ensure that the cross-section and position of the air outlet beam can generate changes in the first span direction.

[0021] In one embodiment, the pose adjusting part includes a telescopic driving part arranged on the main body part. The telescopic driving part is rotatably connected to the blowing part, and the telescopic driving part is used to adjust the pose of the blowing part through telescopic deformation.

[0022] With such a setting, the pose switching of the blowing part relative to the main body part is more convenient, the pose adjusting part is more reliable and durable, and the assembly connection between the pose adjusting part, the blowing part and the main body part is easy to achieve.

[0023] In one embodiment, the main body part has a reference center line. The blowing device includes a sensor communicatively connected to the pose adjusting part. The sensor is used to sense the position of the object to be blown relative to the reference center line. The pose adjusting part drives the air outlet to blow out the air outlet beam towards the object to be blown nearby according to the sensing result of the sensor.

[0024] With such a setting, the blowing device has the function of adaptively adjusting the flow velocity direction of the air outlet beam to follow the movement of the object to be blown, breaking through the condition limitation that the position of the object to be blown needs to be fixed in existing similar products, ensuring that the air outlet beam can blow directly on the objects to be blown located at different positions along a shorter flow trajectory to a greater extent under different use conditions, and maximizing the wind force effect of the air outlet beam.

[0025] In one embodiment, the pose adjusting part drives the blowing part to the following according to the sensing result of the sensor:

[0026] When the object to be blown and one of the blowing parts are on the same side or different sides of the diversion surface, and the distance from the object to be blown to the diversion surface is less than the first critical value, the blowing part is on the first side of the diversion surface, and the air outlet of the blowing part faces the second side of the diversion surface;

[0027] When the object to be blown and one of the blowing parts are on the same side of the diversion surface, and the distance from the object to be blown to the diversion surface is greater than or equal to the second critical value, the object to be blown and the blowing part are on the first side of the diversion surface, and the air outlet of the blowing part faces away from the second side of the diversion surface; where:

[0028] The absolute value of the second critical value is greater than the absolute value of the first critical value, the diversion surface includes the reference center line and is perpendicular to the first span direction.

[0029] With such a setting, the blowing device has the function of configuring different air outlet intervals for objects to be blown at different positions, so that the air outlet interval where the air outlet beam is located is adapted to the position of the object to be blown. The air outlet only needs to switch between two states of facing the second side of the diversion surface and facing away from the second side of the diversion surface at least, reducing the frequency of adjustment of the distribution and the blowing range of the air outlet beam in the first span direction, while taking into account the range of the air outlet beam covering the object to be blown and the blowing force on the object to be blown.

[0030] In one of the embodiments, the number of blowing parts is multiple, at least two blowing parts are respectively arranged on both sides of the diversion surface, and the pose adjusting part can alternatively drive two blowing parts on both sides of the diversion surface to blow out the air outlet beam towards the object to be blown nearby, or can also drive the two blowing parts to blow out the air outlet beam towards the object to be blown nearby at the same time.

[0031] With such a setting, the blowing device has the function of adjusting the wind force of the air outlet beam in multiple gears, and the user can choose to blow by two blowing parts at the same time or only by one blowing part according to their own needs.

[0032] In one of the embodiments, the main body part has a reference center line, the blowing parts are configured to be multiple and arranged around the reference center line, and each blowing part can rotate around its own commutation axis so that the angle between the air outlet direction of each air outlet and the reference center line can be changed.

[0033] With such a setting, the air outlet beams of multiple blowing parts can rotate around the reference center line, and the air outlet beam blown out by each air outlet can be independently adjusted in flow velocity direction, improving the use convenience of the blowing device and increasing the type of air outlet modes of the blowing device. It allows the user to flexibly adjust the air outlet beam direction of each air outlet according to their usage preferences, and also allows the blowing device to blow objects to be blown with greatly different sizes and randomly irregular shapes under different usage conditions.

[0034] In one embodiment, the number of pose adjusting members is multiple, and the pose adjusting members are respectively connected to the blowing parts one by one, and each pose adjusting member can independently drive the corresponding blowing part to rotate.

[0035] With such an arrangement, the flow velocity direction of the air flow bundle blown out from each air outlet can be independently adjusted, which improves the usability of the blowing device and increases the types of air outlet modes of the blowing device.

[0036] In one embodiment, each commutation axis is perpendicular to the reference center line, each blowing part is provided with an air outlet in the shape of a strip-shaped opening, and the extending direction of each air outlet is perpendicular to the commutation axis corresponding to the air outlet.

[0037] With such an arrangement, the air flow bundle blown out from the air outlet can flow along the plane formed by the air outlet and the reference center line.

[0038] In one embodiment, the two commutation axes of at least two blowing parts are symmetrically distributed about the reference center line, and the two blowing parts are symmetric about the reference center line.

[0039] With such an arrangement, the air flow bundles blown out from the two blowing parts are symmetric about the reference center line. When the object to be blown is located at the position passed by the reference center line, the object to be blown can simultaneously receive two air flow bundles flowing symmetrically about the reference center line, so that the air flow bundles are concentrated on blowing the object to be blown. In addition, the two symmetric air flow bundles can also blow to both sides of the reference center line, so that the air flow bundles are diffused over a larger range.

[0040] In one embodiment, the extending direction of the reference center line is perpendicular to the first span direction; and / or, the extending direction of the reference center line is perpendicular to the second span direction.

[0041] With such an arrangement, the combined arrangement of multiple blowing parts is more reasonable. Under the coordinated cooperation of the control member and the air guiding member, the air outlets of each blowing part can change their positions and shapes in the first span direction, and the air outlets of each blowing part can also change their positions and shapes in the second span direction.

[0042] In one embodiment, the air guiding member has an air guiding opening communicated with the air outlet. The air guiding opening is used for discharging the air flow bundle, and the air guiding member is used for changing the distribution of the air guiding opening in the second span direction by moving relative to the blowing part, where the first span direction and the second span direction are different directions.

[0043] With such an arrangement, the air guiding member can change the initial position where the air flow bundle blows away from the blowing device, so that the root of the air flow bundle changes its position in the second span direction, and further, the flow trajectory and flow direction of the air flow bundle can be changed accordingly.

[0044] In one embodiment, the air guiding member includes a swing leaf rotatably disposed in the blowing portion. An air guiding opening is formed in a side region of the swing leaf. The swing leaf is configured to change the inclination angle of the side region of the swing leaf by rotating relative to the blowing portion; and / or,

[0045] The air guiding member includes an exhaust member rotatably disposed in the blowing portion. The exhaust member is provided with an air guiding opening. The exhaust member is configured to change the opening orientation of the air guiding opening by rotating relative to the blowing portion.

[0046] Compared with the prior art, the blowing device of the present invention adjusts the spatial distribution of the air storage cavity in the first span direction through a control member, thereby completing the adjustment of the spatial distribution of the air outlet through which the air beam can be blown out in the first span direction. And the air guiding member completes the adjustment of the spatial distribution of the air beam in the second span direction. The control member and the air guiding member cooperate with each other to jointly achieve a large-range adjustment of the spatial distribution and blowing range of the air beam in the first span direction and the second span direction, and can meet the requirements of adjusting the air-receiving area range and air-receiving direction of the object to be blown in multiple spatial dimensions under different use conditions, as well as the blowing requirements for the object to be blown to move relative to the blowing device in multiple spatial dimensions.

[0067] The present invention provides a blowing device 100, and the blowing device 100 has different usage occasions and purposes in different embodiments. In some embodiments, the blowing device 100 is a heater. When the heater is installed in a bathroom to provide an air outlet air beam for the user or the bathroom, the heater is also called a ceiling heater. Of course, the heater can also be installed and applied in other occasions; in other embodiments, the blowing device 100 can also be a warm air blower, a dryer, a fresh air blower, etc. The following description of the structure, assembly, operating principle and use of the blowing device 100 will be exemplified by a ceiling heater applied in a bathroom.

[0068] Referring to Figure 1 , the blowing device 100 includes a main body portion 10 and a blowing portion 20. The main body portion 10 includes a chassis 12 and a wind driving portion 11. In some embodiments, an air duct 14 is arranged in the chassis 12, and the wind driving portion 11 is used to drive air to flow along the air duct 14 to form an air flow. The blowing portion 20 is provided on the main body portion 10 and has a cavity 211 that can communicate with the air duct 14. The cavity 211 penetrates through the blowing portion 20 and forms a blowing port 212. The blowing portion 20 can obtain the air flow in the air duct 14 and temporarily store these airs in the cavity 211. The blowing port 212 is used to release the air in the cavity 211 to form an air outlet air beam. After the air outlet air beam is discharged, it can either diffuse in the bathroom or blow towards the user or a specified object. Unless otherwise specified, hereinafter, the user and the specified object that can be blown by the air outlet air beam are defined as the objects to be blown, and the state in which the blowing device 100 is blowing out the air outlet air beam is called the blowing operation condition of the blowing device 100.

[0069] In other embodiments, the air duct 14 can also be omitted while the air driving part 11 is retained. After the air driving part 11 is started, it can directly drive the air flow to flow towards the cavity 211. Of course, the air driving part 11 can also be omitted. For example, when the air driving part 11 and the blowing device 100 are two product units that can be sold independently, the air driving part 11 may not be mounted in the main body part 10 of the blowing device 100. Instead, the main body part 10 and an external independent air driving part 11 are assembled and used. At this time, the main body part 10 serves as the place where the air flow is formed. After the air driving part 11 is installed behind the main body part 10, the air driving part 11 drives the air to flow in the main body part 10 to form an air flow. Whether the main body part 10 is equipped with the air driving part 11 or not, the main body part 10 is the place where the air flow is formed.

[0070] The ceiling lamp is installed in the ceiling space above the bathroom ceiling. The ceiling space is formed between the side of the ceiling board facing away from the ground and the indoor ceiling. In some embodiments, after the blowing device 100 serving as the ceiling lamp is installed in place in the ceiling space, the air outlet 212 is located on the side of the main body part 10 relatively close to the ground and faces the ground. The side of the main body part 10 relatively close to the ground is all located in the same plane parallel to the ceiling board. Optionally, the side of the main body part 10 close to the ground and the side of the ceiling board close to the ground are located in the same horizontal plane. The first span direction and the second span direction are two different horizontal directions respectively, that is, both the first span direction and the second span direction are parallel to the side of the ceiling board close to the ground. In other embodiments, after the blowing device 100 is installed in place in the ceiling space or other positions in the room, the first span direction and the second span direction do not have to be horizontal directions parallel to the ceiling board or the ceiling, as long as the first span direction and the second span direction are two different directions respectively.

[0071] Refer to Figures 2 to 3 、 Figures 4 to 8 In some embodiments, the air driving part 11 includes a centrifugal fan 111 installed in the chassis 12. The chassis 12 is in a cuboid shape and includes a first surface 121 and a second surface 122 arranged opposite to each other. The centrifugal fan 111 is arranged between the first surface 121 and the second surface 122. The number of the blowing parts 20 is multiple. The blowing parts 20 at least include a first blowing part 201 arranged outside the first surface 121 and a second blowing part 202 arranged outside the second surface 122. The air duct 14 is arranged in the internal space of the chassis 12 and includes a main flow channel 141 surrounding the outer peripheral side of the centrifugal fan 111, and also includes a first branch channel 142 bifurcated from the main flow channel 141. The downstream end of the main flow channel 141 penetrates through the first surface 121 to lead to the cavity 211 of the first blowing part 201, and one end of the first branch channel 142 far from the main flow channel 141 penetrates through the second surface 122 to lead to the cavity 211 of the second blowing part 202.

[0072] Further, in some embodiments, the blowing device 100 has a ventilation function and further includes a ventilation part 13 provided in the main body part 10 and having a ventilation opening 131. Refer to Figure 1 , Figures 4 to 8 , the ventilation part 13 is installed on the chassis 12, the ventilation opening 131 communicates with the internal space of the chassis 12, the air duct 14 further includes a second branch duct 143 branched from the main flow duct 141, and the position where the main flow branch duct communicates with the second branch duct 143 is downstream of the position where the main flow duct 141 communicates with the first branch duct 142, that is, when the air flows along the main flow duct 141, it first passes through the first branch duct 142 and then passes through the second branch duct 143. One end of the second branch duct 143 away from the main flow duct 141 penetrates through the chassis 12 to communicate with the ventilation opening 131, and the ventilation opening 131 communicates with the outdoor space. When the blowing device 100 operates the ventilation function, the blowing device 100 first inhales the indoor waste gas into the air duct 14, and then flows along the main flow duct 141 under the drive of the air driving part 11, and finally flows out of the ventilation opening 131 through the second branch duct 143 to be discharged outdoors.

[0073] For convenience of description, the cavity 211 of the first blowing part 201 will be referred to as the first cavity and the cavity 211 of the second blowing part 202 will be referred to as the second cavity hereinafter. The first cavity penetrates through the first blowing part 201 to form a first blowing port 2121, and the second cavity penetrates through the second blowing part 202 to form a second blowing port 2122. Figures 1 to 13 In the illustrated embodiment, the first surface 121 and the second surface 122 are parallel and spaced apart, the spacing direction between the first surface 121 and the second surface 122 is consistent with the first span direction of the main body part 10, the first span direction is the horizontal direction perpendicular to the first surface 121 and the second surface 122, the first blowing part 201 and the second blowing part 202 are arranged along the first span direction, and the first cavity and the second cavity are also arranged along the first span direction.

[0074] It can be understood that the first span direction does not necessarily have to be parallel to the horizontal direction; the first surface 121 and the second surface 122 do not necessarily have to be spaced apart along the first span direction; the air driving part 11 may further include other air source devices and is not limited to the centrifugal fan 111; the air driving part 11 does not necessarily have to be arranged between the first surface 121 and the second surface 122; the number of the blowing parts 20 and the number of the cavities 211 may also be respectively set to one only. When the number of the blowing parts 20 and the number of the cavities 211 are multiple, the queue direction formed by the multiple blowing parts 20 may also form a non-90° angle with the first span direction, as long as it is satisfied that the multiple cavities 211 are arranged in sequence in the first span direction. Of course, this limitation does not apply when the blowing device 100 has only one cavity 211.

[0075] Further, refer to Figures 2 to 3 , and at the same time refer to Figure 1 , Figures 9 to 13, in some embodiments, the main body portion 10 further includes a first side cavity 151 disposed outside the first surface 121 and a second side cavity 152 disposed outside the second surface 122. The first side cavity 151 and the second side cavity 152 are respectively formed by bending and twisting two plate-like elements. The first blowing portion 201 and the second blowing portion 202 are respectively disposed in the first side cavity 151 and the second side cavity 152. The first cavity communicates with the main flow channel 141 through the first side cavity 151, and the second cavity communicates with the first branch channel 142 through the second side cavity 152. The two plate-like elements for forming the first side cavity 151 and the second side cavity 152 can protect the blowing portion 20 and gather the air blown out from the air duct 14 to prevent the air from escaping and being unable to be fully obtained by the first blowing portion 201 and the second blowing portion 202.

[0076] In some embodiments, the blowing device 100 further includes a heater (not shown in the figure). The heater is used to increase the temperature of the air flow bundle of the blown air so that the blowing device 100 has the function of heating or maintaining warmth. The heater can be disposed in the air driving portion 11, or can be disposed in the air duct 14, or can also be disposed in the cavity 211 of the blowing portion 20 or at the air outlet 212. The type and structure of the heater are not limited.

[0077] It should be noted that the present invention does not limit the number of the blowing portions 20, nor does it particularly limit the number of the cavities 211 and the air outlets 212. In the case where the blowing device 100 has one or more blowing portions 20 and has a plurality of cavities 211 and air outlets 212, when the blowing device 100 operates in the blowing condition, the air duct 14 can communicate with all the cavities 211 so that all the air outlets 212 blow out the air flow bundle, or can selectively communicate with some of the cavities 211 so that the air outlets 212 formed by the cavities 211 connected to the air duct 14 blow out the air flow bundle.

[0078] For the convenience of description, hereinafter, the cavity 211 that can obtain the air flow generated by the main body portion 10 and can blow out the air flow bundle will be defined as the air storage cavity. In Figures 1 to 13 the illustrated embodiment, the air storage cavity specifically refers to: the part of the cavity 211 that is in a dredged state with the air duct 14 so as to be able to obtain the air flow in the air duct 14. Specifically, although the main flow channel 141 leads to the first cavity, only when the air duct 14 is in Figure 6 and Figure 7 the illustrated state, the main flow channel 141 and the first cavity are in a dredged state, and at this time the first cavity becomes the air storage cavity; similarly, although the first branch channel 142 leads to the second cavity, only when the air duct 14 is in Figure 5 , Figure 6 and Figure 8When in the state shown, the first branch 142 and the second cavity are in a communicating state, and at this time, the second cavity becomes the air storage cavity. The state transformation and function introduction of the air duct 14 will be elaborated in detail later, and will not be described here for the time being. It should also be added that the air storage cavity refers to the cavity 211 that is capable of obtaining the air flow generated by the main body 10 and thus blowing out the air beam, and should not be understood as the cavity 211 storing air.

[0079] The blowing device 100 of the present invention further includes a control member 30 and a wind guiding member 40. The control member 30 is movably provided on the main body 10 and is used to change the distribution state of the air storage cavity in the first span direction of the main body 10. Changing the distribution state of the air storage cavity in the first span direction will cause the distribution state of the part in the first span direction that communicates with the air storage cavity and can blow out the air beam in the air outlet 212 to change. The part in the air outlet 212 that communicates with the air storage cavity and can blow out the air beam is simply referred to as the air beam outlet; the wind guiding member 40 is provided on the blowing part 20 and has a wind guiding port 412, and can guide the air beam blown out from the air outlet 212 through the wind guiding port 412, and the air beam finally leaves the blowing device 100 from the wind guiding port 412.

[0080] Without considering the wind guiding member 40, as the distribution state of the air storage cavity in the first span direction is changed, the distribution state of the air beam outlet in the first span direction changes accordingly, and the change in the distribution state of the air beam in the first span direction is also completed.

[0081] In some embodiments, the wind guiding member 40 is movably provided on the blowing part 20, and can change the shape, size, quantity, position and opening orientation of the wind guiding port 412 by moving relative to the blowing part 20, so as to adjust and control the air beam blown out from the air outlet 212 through the wind guiding port 412, and further realize that the wind guiding member 40 changes the distribution state of the air beam in the second span direction of the main body 10.

[0082] The variables that affect the distribution state of the air storage cavity in the first span direction, that is, the variables that affect the distribution state of the air beam outlet in the first span direction include: the size, position, attitude and arrangement quantity of the air storage cavity in the first span direction. The size of the air storage cavity in the first span direction will directly determine the size of the air beam outlet in the first span direction. The position and attitude of the air storage cavity in the first span direction will directly determine the position and attitude of the air beam outlet in the first span direction. The arrangement quantity of the air storage cavity in the first span direction will directly determine the position and attitude of the air beam outlet in the first span direction. Changing any one of the size, position, attitude and arrangement quantity of the air beam outlet in the first span direction will cause a change in the distribution state of the air beam outlet in the first span direction.

[0083] The distribution state of the air outlet air beam in the second span direction is directly related to the distribution of the air guiding opening 412 in the second span direction. The variables that affect the distribution of the air guiding opening 412 in the second span direction, that is, the variables that affect the distribution state of the air outlet air beam in the second span direction, include: the size, position, attitude, and arrangement quantity of the air guiding opening 412 in the second span direction. The size of the air guiding opening 412 in the second span direction will directly determine the size of the space occupied by the air outlet air beam in the second span direction. The position and attitude of the air guiding opening 412 in the second span direction will directly determine the flow direction of the air outlet air beam and the position of the flow trajectory of the air outlet air beam in the second span direction. The arrangement quantity of the air guiding opening 412 in the second span direction will directly determine the arrangement quantity of the air outlet air beam in the second span direction.

[0084] In some embodiments, the number of the air guiding openings 412 is multiple. The air guiding member 40 selectively opens some or all of the air guiding openings 412 by moving relative to the blowing portion 20 to change the arrangement quantity of the air outlet air beam in the second span direction. In some other embodiments, the air guiding member 40 changes the opening size of the air guiding opening 412 by moving relative to the blowing portion 20 to change the size of the space occupied by the air outlet air beam in the second span direction. In still some other embodiments, the air guiding member 40 changes the position, attitude or orientation of the air guiding opening 412 by moving relative to the blowing portion 20 to change the flow direction of the air outlet air beam and change the position of the flow trajectory of the air outlet air beam in the second span direction.

[0085] Adjusting the spatial distribution of the air storage cavity in the first span direction can realize the adjustment of the spatial distribution of the air blowing openings 212 corresponding to the air storage cavity in the first span direction. The air blowing openings 212 corresponding to the air storage cavity are the parts of the air blowing openings 212 that can blow out the air outlet air beam. Combining with the adjustment of the spatial distribution of the air outlet air beam in the second span direction, finally, through the coordinated cooperation of the control member 30 and the air guiding member 40, a large-range adjustment of the spatial distribution and blowing range of the air outlet air beam in the first span direction and the second span direction is realized, so as to meet the requirements of adjusting the air receiving area and air receiving direction angle of the object to be blown receiving the air outlet air beam in multiple spatial dimensions under different use conditions, and meet the blowing requirements for the object to be blown to move relative to the blowing device 100 in multiple spatial dimensions.

[0086] Refer back to Figure 1 and at the same time refer to Figures 4 to 8, the control member 30 includes an on-off control member 32 movably disposed in the air duct 14. The on-off control member 32 selectively switches the air duct 14 to communicate with the first chamber and / or the second chamber by moving relative to the air duct 14, so as to selectively make the first chamber and / or the second chamber become an air storage chamber capable of blowing out an air beam. The on-off control member 32 includes a first air damper 321 and a second air damper 322. The first air damper 321 and the second air damper 322 are rotatably installed inside the chassis 12. The first air damper 321 has three stopping positions. The first stopping position of the first air damper 321 is as shown in Figure 4 , Figure 7 . The second stopping position of the first air damper 321 is as shown in Figure 5 , Figure 6 . The third stopping position of the first air damper 321 is as shown in Figure 8 . The second air damper 322 has two stopping positions. The first stopping position of the second air damper 322 is as shown in Figure 4 , Figure 5 . The second stopping position of the second air damper 322 is as shown in Figure 6 , Figure 7 and Figure 8 .

[0087] Specifically, when the on-off control member 32 is in the first state shown in Figure 7 , the main flow channel 141 is unblocked from the first chamber. The air driving part 11 can drive the air in the air duct 14 to flow along the main flow channel 141 to the first chamber, and the first chamber becomes an air storage chamber. The first air damper 321 closes one end of the first branch channel 142 relatively close to the main flow channel 141, so that the one end of the first branch channel 142 relatively close to the main flow channel 141 is blocked from the second chamber. The second air damper 322 closes one end of the second branch channel 143 relatively close to the main flow channel 141, so that the one end of the second branch channel 143 relatively close to the main flow channel 141 is blocked from the outdoor space, and no air will flow along the first branch channel 142 to the second chamber or along the second branch channel 143 to the outdoor;

[0088] When the on-off control member 32 is in the second state shown in Figure 8 , the first air damper 321 opens one end of the first branch channel 142 relatively close to the main flow channel 141, so that the main flow channel 141, the first branch channel 142 and the second chamber are unblocked. At the same time, the main flow channel 141 is blocked from the first chamber. The second air damper 322 closes one end of the second branch channel 143 relatively close to the main flow channel 141, so that the one end of the second branch channel 143 relatively close to the main flow channel 141 is blocked from the outdoor space. At this time, the air driving part 11 drives the air in the air duct 14 to flow along the main flow channel 141 first, and then all these air flows into the first branch channel 142 and enters the second chamber. The second chamber becomes an air storage chamber, and no air will flow into the first chamber or along the second branch channel 143 to the outdoor;

[0089] When the on-off control member 32 is in the Figure 6 third state shown in the figure, the first air door 321 opens one end of the first branch channel 142 relatively close to the main flow channel 141, so that the main flow channel 141, the first branch channel 142 and the second cavity are unblocked. At the same time, the main flow channel 141 and the first cavity are unblocked. The second air door 322 closes one end of the second branch channel 143 relatively close to the main flow channel 141, so that one end of the second branch channel 143 relatively close to the main flow channel 141 is blocked from the outdoor space. At this time, the air driving part 11 drives the air in the air duct 14 to flow along the main flow channel 141. Subsequently, a part of this air flows into the first branch channel 142 and enters the second cavity, and another part flows into the first cavity. Both the first cavity and the second cavity become air storage cavities, and no air will flow to the outdoor along the second branch channel 143;

[0090] When the on-off control member 32 is in the Figure 4 fourth state shown in the figure, the second air door 322 opens one end of the second branch channel 143 relatively close to the main flow channel 141, so that one end of the second branch channel 143 relatively close to the main flow channel 141 is unblocked from the outdoor space. At the same time, the second air door 322 blocks the main flow channel 141 and the first cavity. The first air door 321 closes one end of the first branch channel 142 relatively close to the main flow channel 141, so that one end of the first branch channel 142 relatively close to the main flow channel 141 is blocked from the second cavity. At this time, the air driving part 11 drives the air in the air duct 14 to flow along the main flow channel 141. Subsequently, all of it flows into the second branch channel 143 and is discharged to the outdoor, and no air will enter the first cavity or flow into the second cavity along the first branch channel 142;

[0091] When the on-off control member 32 is in the Figure 5 fifth state shown in the figure, the second air door 322 opens one end of the second branch channel 143 relatively close to the main flow channel 141, so that one end of the second branch channel 143 relatively close to the main flow channel 141 is unblocked from the outdoor space. At the same time, the second air door 322 blocks the main flow channel 141 and the first cavity. The first air door 321 opens one end of the first branch channel 142 relatively close to the main flow channel 141, so that one end of the first branch channel 142 relatively close to the main flow channel 141 is unblocked from the second cavity. The second cavity becomes an air storage cavity. At this time, under the drive of the air driving part 11, a part of the air in the main flow channel 141 flows into the first branch channel 142 and enters the second cavity, and another part flows into the second branch channel 143 to be discharged to the outdoor.

[0092] Obviously, the on-off control member 32 switches between the first state to the fifth state described above. Not only can it selectively make the first cavity and / or the second cavity into an air storage cavity to change the distribution of the air storage cavity in the first span direction, specifically, to change the arrangement number of the air storage cavities in the first span direction, but also it can start the ventilation function while the blowing device 100 pauses blowing air to the object to be blown or while the blowing device 100 blows air to the object to be blown through the air storage cavity formed by the second cavity, improving the convenience of the blowing device 100.

[0093] In some embodiments, the blowing part 20 is movably provided on the main body part 10. The control member 30 includes a posture adjusting member 31 provided on the main body part 10. The posture adjusting member 31 is connected to the blowing part 20 and can output power to the blowing part 20, for driving the blowing part 20 to move relative to the main body part 10 so that the blowing part 20 generates changes in shape, size or position at least in the first span direction, so that the cavity 211 of the driven blowing part 20 becomes an air storage cavity that can generate changes in shape, size or position in the first span direction, thereby changing the distribution of the air storage cavity in the first span direction. Refer to Figure 2 and Figure 3 , the first blowing part 201 and the second blowing part 202 are respectively provided in the first side cavity 151 and the second side cavity 152. Their structures, the connection methods with the main body part 10 respectively, and their movement modes relative to the main body part 10 are all the same. Next, the specific structure and movement mode of the blowing part 20 will be introduced taking the first blowing part 201 as an example.

[0094] Refer to Figures 9 to 10 、 Figure 12 , both the first blowing part 201 and the second blowing part 202 include a first pivoting part 221 and a second pivoting part 222. The posture adjusting member 31 includes a first posture adjusting member 311 and a second posture adjusting member 312 with the same structure. The first posture adjusting member 311 is used to drive the first blowing part 201, including a telescopic driving member 3101 installed in the first side cavity 151. The second posture adjusting member 312 is used to drive the second blowing part 202, including a telescopic driving member 3101 installed in the second side cavity 152. The first blowing part 201 and the second blowing part 202 are respectively rotatably installed on the first surface 121 and the second surface 122 through their respective first pivoting parts 221. The first pivoting part 221 forms a commutation axis for the blowing part 20 to rotate relative to the main body part 10. The telescopic driving member 3101 includes a telescopic output part rotatably connected to the second pivoting part 222. The telescopic driving member 3101 drives the blowing part 20 to rotate around the commutation axis by its own telescopic deformation, using the telescopic output part to change the posture of the first blowing part 201 and / or the second blowing part 202, so as to change the position and posture of the first cavity and / or the second cavity in the first span direction.

[0095] Regardless of the commutation axis of the first air blowing unit 201 or the second air blowing unit 202, or the commutation axes of more air blowing units 20, the extending direction of each commutation axis forms an angle with the first span direction. The formed angle can be an inclined angle other than 90°, or can be 90°, so as to ensure that the air blowing unit 20 can surely rotate around the commutation axis under the drive of the telescopic driving member 3101, so that the position and attitude of the cavity 211 in the first span direction are changed.

[0096] In Figures 1 to 3 、 Figures 10 to 13 In the illustrated embodiment, the first side cavity 151 and the second side cavity 152 are arranged along the first span direction. The commutation axis of the first air blowing unit 201 is parallel to the commutation axis of the second air blowing unit 202. The extending directions of both are perpendicular to the first span direction and are both consistent with the second span direction. After the first air blowing unit 201 and the second air blowing unit 202 rotate around their respective commutation axes, both the first cavity and the second cavity change their positions and attitudes in the first span direction, and do not change their positions and attitudes in the second span direction, so as to ensure that the first air blowing unit 201 and the second air blowing unit 202 can be smoothly moved out of or received into the first side cavity 151 and the second side cavity 152 respectively.

[0097] It can be understood that the pose adjustment member 31 is not limited to the telescopic driving member 3101. In other embodiments, other types of driving sources can also be used as the pose adjustment member 31 to connect and drive the air blowing unit 20 to rotate around the commutation axis.

[0098] Further, referring to Figures 9 to 13 , the direction indicated by the arrow K in the figure is the first span direction, and the second span direction is the direction of the straight line perpendicular to the plane of the drawing. The main body portion 10 has a reference center line, which is schematically shown by a dotted line S in the figure. The blowing device 100 further includes a sensor communicatively connected to the pose adjustment member 31. The sensor uses the reference center line as the coordinate origin for confirming the object to be sensed, and is used to sense the position of the object to be blown relative to the reference center line. The pose adjustment member 31 can obtain the sensing result of the sensor. The sensing result includes the coordinate information of the object to be blown, and drives the air outlet 212 of the air blowing unit 20 to blow out the air beam towards the object to be blown nearby according to the drive control algorithm corresponding to the sensing result. In other words, under the control of the drive control algorithm corresponding to the coordinate information of the object to be blown, the air outlet 212 of the air blowing unit 20 is driven to face the object to be blown, and the distance between the air outlet 212 and the object to be blown reaches the shortest, so that the air beam can reach the object to be blown with the least time consumption.

[0099] Optionally, the extending direction of the reference center line is perpendicular to the first span direction and also perpendicular to the second span direction. After the blowing device 100 is installed in place, for example, when the blowing device 100 of the integrated ceiling heater is installed in the ceiling space, the reference center line extends in the vertical direction, and the first span direction and the second span direction are two mutually perpendicular horizontal directions respectively.

[0100] Figures 9 to 13 In the illustrated embodiment, the first pivot portion 221 of the first blowing portion 201 and the first pivot portion 221 of the second blowing portion 202 are symmetrically arranged with respect to the reference center line, that is, the commutation axes of the first blowing portion 201 and the second blowing portion 202 are symmetrically distributed with respect to the reference center line; the air outlet 212 includes a strip-shaped first air outlet 2121 formed by the first cavity penetrating through the first blowing portion 201 and a strip-shaped second air outlet 2122 formed by the second cavity penetrating through the second blowing portion 202. The extending direction of the first air outlet 2121 is perpendicular to the commutation axis of the first blowing portion 201, and the extending direction of the second air outlet 2122 is perpendicular to the commutation axis of the second blowing portion 202; the first posture adjusting member 311 and the second posture adjusting member 312 are symmetrically installed on both sides of the main body portion 10 with respect to the reference center line. The first posture adjusting member 311 can independently drive the first blowing portion 201 to rotate around its commutation axis, and the second posture adjusting member 312 can independently drive the second blowing portion 202 to rotate around its commutation axis. Of course, it is not excluded that the first posture adjusting member 311 and the second posture adjusting member 312 act simultaneously and drive the first blowing portion 201 and the second blowing portion 202 to rotate simultaneously respectively.

[0101] Optionally, on the basis that the opening of the air outlet 212 is strip-shaped and the extending direction of the opening of the air outlet 212 is perpendicular to the commutation axis of the blowing portion 20 where it is located, regardless of whether the number of the blowing portions 20 is one or more, the commutation axes of each blowing portion 20 are perpendicular to the reference center line, so that when each blowing portion 20 rotates around its own commutation axis, the air outlet 212 of the blowing portion 20 always maintains a state of extending along the same radial direction of the reference center line.

[0102] For the convenience of description, a diversion surface is defined here. The diversion surface is an important basis for confirming the coordinate position information of the object to be blown. It not only includes the reference center line, but also the diversion surface is parallel to the second span direction and perpendicular to the first span direction, that is, the diversion surface is perpendicular to Figures 9 to 13The blowing device 100 is cut by the direction of the drawing plane where it is located. The first blowing part 201 and the second blowing part 202 are respectively located on both sides of the flow splitting surface. When the blowing device 100 operates in the blowing condition, either only the first pose adjusting member 311 can be activated to drive the first blowing port 2121 of the first blowing part 201 to blow the object to be blown nearby, or only the second pose adjusting member 312 can be activated to drive the second blowing port 2122 of the second blowing part 202 to blow the object to be blown nearby. It is also possible to activate the first pose adjusting member 311 and the second pose adjusting member 312 simultaneously to drive the first blowing port 2121 and the second blowing port 2122 to blow the object to be blown nearby respectively.

[0103] Taking the first pose adjusting member 311 and the first blowing part 201 as the research objects, several state modes in which the pose adjusting member 31 drives the blowing port 212 to blow the object to be blown nearby according to the sensing result of the sensor include:

[0104] 1) When the distance from the object to be blown to the flow splitting surface is less than the first critical value, if the first blowing part 201 is located on the first side of the flow splitting surface, then regardless of whether the object to be blown is on the first side or the second side opposite to the first side at this time, the opening of the first blowing port 2121 is inclined towards the second side of the flow splitting surface, and at the same time, the first blowing port 2121 is as much as possible directly facing the object to be blown. The outgoing air beam blown out from the first blowing port 2121 will intersect with the reference center line, as Figure 10 shown in Figure 13 Of course, when the object to be blown and the first blowing part 201 are respectively located on both sides of the flow splitting surface and on the same side of the flow splitting surface, the flow velocity directions of the outgoing air beams blown out from the first blowing port 2121 are different in these two cases;

[0105] 2) When the distance from the object to be blown to the flow splitting surface is greater than or equal to the second critical value (the absolute value of the second critical value is greater than the absolute value of the first critical value), if the first blowing part 201 is arranged on the first side of the flow splitting surface and the object to be blown is also on the first side of the flow splitting surface, then the opening of the first blowing port 2121 faces away from the second side of the flow splitting surface, and at the same time, it is as much as possible directly facing the object to be blown. At this time, the outgoing air beam blown out from the first blowing port 2121 gradually moves away from the reference center line, as Figure 12 shown in

[0106] Similarly, when the distance from the object to be blown to the flow splitting surface is greater than or equal to the second critical value and the second blowing part 202 and the object to be blown are both on the second side of the flow splitting surface, then the opening of the second blowing port 2122 faces away from the first side of the flow splitting surface, and at the same time, it is as much as possible directly facing the object to be blown;

[0106] 3) When the distance from the object to be blown to the flow surface is between the first critical value and the second critical value, if both the object to be blown and the first blowing part 201 are arranged on the first side of the flow splitting surface, the opening of the first blowing port 2121 is Figure 11The vertical opening faces downward. When the object to be blown and the second blowing part 202 are on the same side of the diversion surface, that is, both are on the second side of the diversion surface, the opening of the second air outlet 2122 faces vertically downward and is open.

[0107] For the blowing device 100 used as a bathroom heater, the object to be sensed tracked by the sensor can be parts of a user's body trunk, head, etc.; for blowing devices 100 for other purposes, the object to be sensed tracked by the sensor can also be clothes, materials, products, etc. to be dried or heated. It can be seen that after the blowing device 100 is equipped with a sensor, the blowing device 100 can provide more air outlet direction adjustment modes. It can not only achieve large-range and multi-angle air outlet direction adjustment, but also track the air outlet of the dynamic object to be blown. For the blowing device 100 used as a bathroom heater, it can follow the user with warm air.

[0108] In Figure 1 、 Figures 10 to 13 On the basis of the embodiment shown, the blowing device 100 can further include more blowing parts 20. These blowing parts 20 can be arranged around the reference center line. Each blowing part 20 can rotate relative to the main body part 10 around its respective commutation axis, so that the angle between the air outlet direction of the air outlet 212 of each blowing part 20 and the reference center line can be adjusted and changed, so as to adjust the distribution conditions of the cavities 211 of the respective blowing parts 20 in terms of shape, size, position, etc. along the first span direction.

[0109] Furthermore, the control part 30 can further include more pose adjustment parts 31. The multiple pose adjustment parts 31 are respectively connected to the multiple blowing parts 20 in a one-to-one correspondence. Each pose adjustment part 31 can independently drive the corresponding blowing part 20 to rotate relative to the main body part 10. The user can select one or some of the blowing parts 20 to blow air according to actual needs. Based on this, one or some of the pose adjustment parts 31 drive the corresponding blowing parts 20 to rotate, or all the blowing parts 20 can be selected to blow air simultaneously. Based on this, all the pose adjustment parts 31 drive the corresponding blowing parts 20 to rotate simultaneously.

[0110] In some embodiments, the control member 30 includes two or more pose adjustment members 31. At least two pose adjustment members 31 are respectively disposed on both sides of the flow splitting surface, namely, the first pose adjustment member 311 and the second pose adjustment member 312. The blowing part 20 includes two or more individuals. At least two blowing parts 20 are respectively disposed on both sides of the flow splitting surface, namely, the first blowing part 201 connected to the first pose adjustment member 311 and the second blowing part 202 connected to the second pose adjustment member 312. When the wind force required by the user is relatively small, one of the first blowing part 201 and the second blowing part 202 can be selected to blow. When the wind force required by the user is relatively large, the first blowing part 201 and the second blowing part 202 can be made to blow simultaneously. Refer to Figure 13 , Figure 13 In the state shown, the first blowing part 201 and the second blowing part 202 are symmetrical about the reference center line. The opening of the first air outlet 2121 is inclined towards the right side of the flow splitting surface, that is, the side where the second blowing part 202 is located. The opening of the second air outlet 2122 is inclined towards the left side of the flow splitting surface, that is, the side where the first blowing part 201 is located. The air flow bundles of the first air outlet 2121 and the air flow bundles of the second air outlet 2122 meet at the reference center line. The flow trajectories of the two air flow bundles are generally in a V shape and are symmetrical about the flow splitting surface.

[0111] Further, in a wind direction mode of large-range blowing not shown in the figure, the first blowing part 201 and the second blowing part 202 blow simultaneously. The first blowing part 201 and the second blowing part 202 are respectively located on the first side and the second side of the flow splitting surface. The opening of the first air outlet 2121 faces away from the second side, and the opening of the second air outlet 2122 faces away from the first side. The air flow bundles of the first air outlet 2121 and the air flow bundles of the second air outlet 2122 both gradually move away from the reference center line. The flow trajectories of the two air flow bundles are generally in a figure-eight shape and are symmetrical about the flow splitting surface.

[0112] With such a setting, the blowing device 100 can provide a richer air outlet wind direction mode. It can blow air concentratedly to a local area according to the Figure 13 state shown, or can discharge the air flow bundles dispersedly in a larger range according to the wind direction mode of large-range blowing described above, so as to preheat and dry places such as bathrooms.

[0113] In some embodiments, the air guiding member 40 includes a swinging member 41 movably disposed on the blowing portion 20. The swinging member 41 may be a single swinging blade 411 or multiple swinging blades 411 arranged side by side with intervals therebetween. The side region of the swinging member 41 includes the side region of the swinging blade 411. The side region of the swinging blade 411 is communicated with a part of the air outlet 212 that communicates with the air storage cavity. After the air in the air storage cavity flows out of the air outlet 212, it passes through the side region of the swinging blade 411, and then forms an air outlet beam occupying a certain space volume under the guidance and regulation of the swinging blade 411. The swinging blade 411 can move relative to the blowing portion 20 to change the distribution state of the side region of the swinging blade 411 in the second span direction, thereby changing the outlet direction of the air outlet beam.

[0114] Figures 2 to 3 In the illustrated embodiment, the swinging member 41 is rotatably mounted on the blowing portion 20 and includes at least two swinging blades 411 arranged side by side with intervals therebetween. The axis of rotation of the swinging member 41 relative to the blowing portion 20 is defined as the sweeping axis. The side regions of two adjacent swinging blades 411 form an air guiding opening 412 communicated with the air outlet 212. The swinging member 41 changes the orientation of the air guiding opening 412 by rotating relative to the blowing portion 20, thereby changing the size and attitude of the air guiding opening 412 in the second span direction. The size and attitude of the air guiding opening 412 will determine the flow velocity direction of the air outlet beam and the spatial shape occupied by the air outlet beam. Optionally, taking the blowing device 100 of the bathroom heater as an example, the swinging member 41 can reciprocally rotate relative to the blowing portion 20 around the sweeping axis to realize sweeping the user. When the opening of the air outlet 212 faces directly towards the ground, the extending direction of the sweeping axis is perpendicular to the second span direction and is consistent with the first span direction at the same time.

[0115] The variables affecting the distribution state of the side region of the swinging blade 411 in the second span direction include: the size, position and attitude of the side region in the second span direction, and the arrangement quantity of the side region in the second span direction. The size of the side region in the second span direction will determine the position and size of the air guiding opening 412 of the swinging blade 411 in the second span direction. The position and attitude of the side region in the second span direction will determine the position and attitude of the air guiding opening 412 of the swinging blade 411 in the second span direction, thereby determining the inclination angle of the side of the swinging blade 411. The arrangement quantity of the side region in the second span direction will determine the arrangement quantity of the air guiding opening 412 in the second span direction.

[0116] In some embodiments not shown in the figures, the air guide member 40 includes an exhaust member movably disposed in the blowing portion 20. The exhaust member is provided with an air guide opening, and the air guide opening is communicated with a portion of the air blowing opening 212 that communicates with the air storage cavity. After the air in the air storage cavity flows out of the air blowing opening 212, it will continue to flow and be discharged through the air guide opening to form an air outlet beam. The opening direction of the air guide opening will affect the flow velocity direction of the air outlet beam and the spatial shape occupied by the air outlet beam. The exhaust member changes the opening direction of the air guide opening by moving relative to the blowing portion 20, so as to achieve the purpose of changing the air outlet direction of the air outlet beam. Optionally, the blowing portion 20 has a cylindrical structure, the air blowing opening 212 penetrates through the side wall of the blowing portion 20, the exhaust member is rotatably disposed on the blowing portion 20, and the axis of rotation of the exhaust member relative to the blowing portion 20 is defined as the sweeping axis. The sweeping axis can be the axis of the blowing portion 20. When the opening of the air blowing opening 212 faces the ground, the extending direction of the sweeping axis is perpendicular to the second span direction and is consistent with the first span direction.

[0117] It can be understood that in other embodiments, the swinging member 41 or the exhaust member may not necessarily rotate reciprocally around the sweeping axis, and may also rotate in a single rotation direction around the sweeping axis, as long as the distribution of the air beam outlet in the second span direction can be changed.

[0118] In some embodiments not shown in the figures, the control member further includes an opening degree adjusting member movably connected to the blowing portion. The opening degree adjusting member can change the opening degree of the air blowing opening of the blowing portion in the first span direction by moving relative to the blowing portion, so that the shape and / or size of the air blowing opening in the first span direction is changed. For example, the opening degree adjusting member is movably disposed on the blowing portion and can cover at least a part of the air blowing opening, and can change the covering area of the air blowing opening by translating relative to the blowing portion; for another example, the opening degree adjusting member is movably disposed in the cavity and can occupy at least a part of the cavity, and can change the volume it occupies in the cavity by translating relative to the blowing portion. The cavity not occupied by the opening degree adjusting member forms an air storage cavity for receiving air. Correspondingly, the part of the air blowing opening that communicates with the cavity not occupied by the opening degree adjusting member realizes the opening degree change in the first span direction.

[0119] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
