TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a wind guide structure, a control method thereof and an air outlet device. BACKGROUND

[0002] At present, the kickboard heater is a heater placed on the ground, which heats air through the internal heating body, and the air is heated near the heating body and then rises to achieve the effect of heating the space.

[0003] The kickboard heater in the related art is generally single-sided air outlet, and air is blown at a fixed angle, which cannot realize the adjustment of the wind direction. SUMMARY

[0004] Embodiments of the present application aim to at least solve one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of embodiments of the present application provides a wind guide structure.

[0006] A second aspect of embodiments of the present application provides an air outlet device.

[0007] A third aspect of embodiments of the present application provides a control method of a wind guide structure.

[0008] Therefore, according to the first aspect of embodiments of the present application, a wind guide structure is provided, which is used in an air outlet device, the air outlet device comprising a shell, the shell being provided with an air outlet, the wind guide structure comprising: a machine body, the machine body being provided with a limiting groove; a limiting piece, the limiting piece being arranged on the machine body and being at least partially movably located in the limiting groove; a trigger assembly, the trigger assembly being movably arranged on the machine body and being connected with the limiting piece; and a wind guide part, the wind guide part being connected with the trigger assembly, under the condition that the trigger assembly is triggered, the trigger assembly can drive at least part of the limiting piece to move in the limiting groove, and can drive the wind guide part to move relative to the machine body, for changing the flow direction of the gas at the air outlet.

[0009] The wind guide structure provided by the embodiments of the present application comprises a machine body, a limiting piece, a trigger assembly and a wind guide part, specifically, the machine body is provided with a limiting groove, the trigger assembly is connected with the limiting piece and the wind guide part, that is, when the trigger assembly is triggered, at least part of the limiting piece will move in the limiting groove in the process of at least part of the wind guide part moving relative to the machine body.

[0010] Since the trigger assembly drives the wind guide part to move relative to the machine body, the flow direction of the gas at the air outlet can be changed, so that the user can adjust the air blowing angle or direction according to the actual needs, which is beneficial to improve the flexibility and comfort of the user using the air outlet device, and further improve the user experience.

[0011] Moreover, as the at least partial limiting member moves in the limiting groove, the movement range of the triggering assembly can be limited, thereby limiting the movement range of the air guiding part, and further enabling the air outlet device to blow air at a set air outlet angle, simplifying the operation process, realizing quick adjustment of the air outlet angle or air outlet direction, and ensuring air outlet effect.

[0012] Optionally, the air guiding part comprises an air guiding plate arranged at the air outlet, and in the case that the triggering assembly is triggered, the air guiding plate moves relative to the machine body, thereby adjusting the air outlet angle at the air outlet.

[0013] Optionally, the air guiding part comprises a volute, the volute has an air outlet part, the air outlet comprises a first air outlet and a second air outlet, and by moving the volute relative to the machine body, the air outlet part can be communicated with the first air outlet or the second air outlet, that is, a suitable air outlet can be selected to blow air according to actual needs, so as to adjust the air outlet direction.

[0014] In addition, the air guiding structure provided by the above technical scheme of the present application also has the following additional technical features:

[0015] In some technical schemes, the limiting member is provided with a first arm, the first arm is movably arranged in the limiting groove and connected with the triggering assembly, the machine body is further provided with a first limiting wall and a second limiting wall in the limiting groove, and along the movement direction of the first arm in the limiting groove, the first limiting wall and the second limiting wall are respectively located on the two sides of the first arm.

[0016] In this technical scheme, the limiting member comprises the first arm, specifically, the first arm is arranged in the limiting groove, and the first arm is connected with the triggering assembly, that is, when the triggering assembly is triggered, the triggering assembly drives the first arm to move in the limiting groove.

[0017] The machine body further comprises a first limiting wall and a second limiting wall, wherein the first limiting wall and the second limiting wall are located in the limiting groove, and along the movement direction of the first arm in the limiting groove, the first limiting wall and the second limiting wall are respectively located on the two sides of the first arm, thereby indirectly limiting the movement range of the air guiding part through the triggering assembly, simplifying the operation process, realizing quick adjustment of the air outlet angle or air outlet direction, and ensuring air outlet effect.

[0018] Specifically, when the triggering assembly is triggered, the triggering assembly drives the first arm to move in the limiting groove along a first direction, at the same time, the triggering assembly drives the air guiding part to move along the first direction, when the first arm abuts against the first limiting wall, the triggering assembly cannot continue to move, so that the air guiding part cannot continue to move, thereby indirectly prompting the user to move into position.

[0019] When the trigger assembly is triggered reversely, the trigger assembly drives the first arm to move in the second direction in the limiting groove, and at the same time, the trigger assembly drives the air guide part to move in the second direction. When the first arm abuts against the second limiting wall, the trigger assembly cannot continue to move, so that the air guide part cannot continue to move, thereby indirectly prompting the user to move to the position, and improving the user operation experience.

[0020] The first direction is opposite to the second direction.

[0021] In some technical solutions, optionally, the limiting piece includes a first elastic piece, the first elastic piece is provided with the first arm, the trigger assembly can move between the first position and the second position; based on the trigger assembly being located at the first position, the first elastic piece has a deformation to make the first arm abut against the first limiting wall; and / or based on the trigger assembly being located at the second position, the first elastic piece has a deformation to make the first arm abut against the second limiting wall.

[0022] In this technical solution, the limiting piece is limited to be the first elastic piece. Specifically, when the trigger assembly moves to the first position, the air guide part is located at the first target position, the first elastic piece has a deformation to make the first arm abut against the first limiting wall, that is, the first elastic piece has a certain pre-tightening force, so that the first arm can abut against the first limiting wall, thereby making the air guide part can be temporarily fixed at the first target position, ensuring that the air outlet device can stably blow air according to the adjusted set air supply angle or air supply direction, improving the air supply effect, and being beneficial to improving the comfort of the user using the air outlet device.

[0023] And / or, when the trigger assembly is located at the second position, the air guide part is located at the second target position, the first elastic piece has a deformation to make the first arm abut against the second limiting wall, that is, the first elastic piece has a certain pre-tightening force, so that the first arm can abut against the second limiting wall, thereby making the air guide part can be temporarily fixed at the second target position, ensuring that the air outlet device can stably blow air according to the adjusted set air supply angle or air supply direction.

[0024] Moreover, when the trigger assembly moves to the first position or the second position, it is not necessary to additionally set a fixing device for fixing the trigger assembly or the air guide part, which is beneficial to simplifying the structure of the air outlet device, optimizing the overall layout of the air outlet device, reducing the number of parts, and further reducing the production cost of the air outlet device.

[0025] In some technical solutions, optionally, in the case that the trigger assembly is located at the first position and the first elastic piece has a deformation to make the first arm abut against the first limiting wall, the first elastic piece has a first deformation amount; in the case that the trigger assembly is located at the second position, the first elastic piece has a second deformation amount, the second deformation amount is greater than the first deformation amount.

[0026] In the technical scheme, when the trigger assembly is located at the first position, the first elastic member has a certain deformation amount, so that the trigger assembly can be temporarily fixed at the first position without other fixing devices, thereby temporarily fixing the air guide part at the first target position, and ensuring that the air supply direction or the air supply angle can be stably set.

[0027] When it is necessary to adjust the air supply angle or the air supply direction, the trigger assembly is triggered, the trigger assembly moves from the first position to the second position, and when the trigger assembly moves to the second position, the deformation amount of the first elastic member increases, so that when it is necessary to adjust the air supply angle or the air supply direction again, the elastic force of the first elastic member can drive the trigger assembly to automatically reset from the second position to the first position, further simplifying the operation process when the air supply angle or the air supply direction is adjusted, and improving the operation experience of the user.

[0028] In some technical schemes, optionally, the body is further provided with a first mounting groove; the first elastic member further comprises a second arm, the second arm and the first arm are respectively located at two ends of the first elastic member, and the second arm is arranged in the first mounting groove.

[0029] In the technical scheme, it is defined that the first elastic member further comprises a second arm, and specifically, the second arm and the first arm are respectively located at two ends of the first elastic member.

[0030] The body is further provided with a first mounting groove, and the second arm is arranged in the first mounting groove, that is, the second arm is fixed in the first mounting groove, so that when the trigger assembly drives the first arm to move in the limiting groove, the deformation amount of the first elastic member can be changed.

[0031] Optionally, the first elastic member comprises a torsion spring.

[0032] Optionally, the length of the first arm is greater than the length of the second arm, that is, the first arm is a long arm, and the second arm is a short arm.

[0033] In some technical schemes, optionally, the body is further provided with a mounting shaft, the mounting shaft is rotationally connected with the trigger assembly, and the trigger assembly can rotate relative to the mounting shaft when the trigger assembly is triggered; wherein an outer wall of the mounting shaft is provided with a second mounting groove, the second mounting groove is communicated with the limiting groove, the first elastic member is sleeved on the mounting shaft and at least partially embedded in the second mounting groove.

[0034] In the technical scheme, it is defined that the body is further provided with a mounting shaft, and specifically, the mounting shaft is rotationally connected with the trigger assembly, that is, when the trigger assembly is triggered, the trigger assembly drives the first arm and the air guide part to rotate relative to the mounting shaft.

[0035] The outer wall of the mounting shaft is provided with a second mounting groove in communication with the limiting groove, the first elastic member is sleeved on the mounting shaft, and at least a portion of the first elastic member is embedded in the second mounting groove, so that the mounting stability and reliability of the first elastic member can be improved, and smooth and stable adjustment of the air supply angle or air supply direction is ensured.

[0036] In addition, since at least a portion of the first elastic member is embedded in the second mounting groove, the thickness of the air guide structure in the axial direction of the mounting shaft is reduced, the occupied space of the air guide structure in the air supply device is reduced, and miniaturization of the air supply device is facilitated.

[0037] Optionally, the second mounting groove is in communication with the first mounting groove.

[0038] In some technical solutions, the trigger assembly is provided with a clamping groove, and a portion of the first arm is embedded in the clamping groove to connect the first arm with the trigger assembly.

[0039] In this technical solution, the trigger assembly is provided with a clamping groove, specifically, the clamping groove is located on the side of the trigger assembly facing the first elastic member. A portion of the first arm is embedded in the clamping groove to connect the first arm with the trigger assembly, so that when the trigger assembly is triggered, the trigger assembly can drive the first arm to move in the limiting groove, to limit the movement range of the trigger assembly, and further limit the movement range of the air guide part, so that the air supply device can supply air at a set air supply angle, simplify the operation process, realize rapid adjustment of the air supply angle or air supply direction, and ensure the air supply effect.

[0040] In some technical solutions, the air guide structure further comprises a limiting assembly arranged on at least one of the body and the trigger assembly; wherein, based on the trigger assembly being located at the first position, the limiting assembly can limit the trigger assembly in the movement direction of the trigger assembly; and / or based on the trigger assembly being located at the second position, the limiting assembly can limit the trigger assembly in the movement direction of the trigger assembly.

[0041] In this technical solution, the air guide structure further comprises a limiting assembly, specifically, the limiting assembly is arranged on at least one of the body and the trigger assembly. Specifically, the limiting assembly is arranged on the body. Alternatively, the limiting assembly is arranged on the trigger assembly. Alternatively, a portion of the limiting assembly is arranged on the body, and another portion of the limiting assembly is arranged on the trigger assembly. The arrangement can be made according to actual needs.

[0042] When the trigger assembly moves to the first position, the air guide part moves to the first target position driven by the trigger assembly, and the limiting assembly can limit the trigger assembly in the movement direction of the trigger assembly, that is, the limiting assembly can keep the trigger assembly in the first position, thereby indirectly keeping the air guide part in the first target position, which is beneficial to ensure that the air outlet device can stably discharge air according to the adjusted air supply angle or air supply direction.

[0043] And / or, when the trigger assembly moves to the second position, the air guide part moves to the second target position driven by the trigger assembly, and the limiting assembly can limit the trigger assembly in the movement direction of the trigger assembly, that is, the limiting assembly can keep the trigger assembly in the second position, thereby indirectly keeping the air guide part in the second target position, which is beneficial to ensure that the air outlet device can stably discharge air according to the adjusted air supply angle or air supply direction.

[0044] In some technical solutions, optionally, the body is further provided with a mounting hole, the trigger assembly is provided with a groove, and the limiting assembly includes a second elastic member and a positioning portion, wherein the second elastic member is provided in the mounting hole, the positioning portion is connected to the second elastic member and is at least partially exposed in the mounting hole, and the positioning portion can move in the mounting hole to move in or out of the groove.

[0045] In this technical solution, the limiting assembly is defined to include a second elastic member and a positioning portion. Specifically, the body is also provided with a mounting hole, the second elastic member is arranged in the mounting hole, the positioning portion is connected to the second elastic member, and at least a portion of the positioning portion is exposed from the mounting hole.

[0046] The positioning portion is capable of moving within the mounting hole to move into or out of the groove. Specifically, when the trigger assembly drives the air guide portion to move from the first position to the second position, or when the trigger assembly drives the air guide portion to move from the second position to the first position, the portion of the positioning portion exposed outside the mounting hole contacts the position where the groove is located, and the positioning portion is forced to move into the mounting hole, causing the second elastic member to deform. When the groove and the positioning portion are opposite to each other, the positioning portion is inserted into the groove under the action of the elastic force of the second elastic member, thereby fixing the trigger assembly in the second position or the first position, and further fixing the air guide portion in the second target position or the first target position.

[0047] It is understandable that when the air supply angle or air supply direction needs to be adjusted, the trigger assembly is triggered again and the positioning portion moves out of the groove to release the movement restriction on the trigger assembly.

[0048] Optionally, when the trigger assembly is in the first position, the first elastic member is deformed so that the first arm rests against the first limiting wall, thereby maintaining the trigger assembly in the first position, and further maintaining the air guide portion in the first target position, thereby fixing one of the air supply angles or air supply directions, and ensuring stable air output at this air supply angle or air supply direction.

[0049] When it is necessary to adjust the air supply angle or the air supply direction, the trigger assembly is triggered and moves from the first position to the second position, the deformation amount of the first elastic member increases, the positioning part is inserted into the groove of the trigger assembly to limit the movement of the trigger assembly, so that the trigger assembly is kept in the second position, and the air guide part is kept in the second target position, so as to realize the fixation of another air supply angle or air supply direction and ensure stable air outlet under the air supply angle or air supply direction.

[0050] That is, the pre-tightening force of the first elastic member is used to realize the fixation of one state, and the limiting assembly is used to realize the fixation of another state, that is, one limiting assembly and the first elastic member can realize the fixation of two states, which is beneficial to simplify the structure of the air outlet device.

[0051] Moreover, compared with the related art that uses a micro switch to control whether the heating element generates heat in two states and then senses whether the trigger assembly is moved to the position, that is, one limiting assembly and the first elastic member can realize the sensing of two states, and the micro switch structure is omitted, which is beneficial to further simplify the structure of the air outlet device and reduce the production cost of the air outlet device.

[0052] Optionally, the number of limiting assemblies is two, when the trigger assembly is located at the first position, the positioning part is inserted into the groove of the trigger assembly to limit the movement of the trigger assembly, so that the trigger assembly is kept in the first position.

[0053] When it is necessary to adjust the air supply angle or the air supply direction, the trigger assembly is triggered again, and the positioning part is moved out of the groove, when the trigger assembly moves to the second position, another positioning part is inserted into another groove of the trigger assembly to limit the movement of the trigger assembly, so that the trigger assembly is kept in the second position.

[0054] It can be understood that when the positioning part is inserted into the groove, a "click" sound is generated, so that the user can intuitively feel the two states of the movement of the trigger assembly, and then indirectly know whether the air guide part is moved to the position, thereby improving the operation experience of the user.

[0055] Optionally, the second elastic member includes a spring.

[0056] In some technical solutions, optionally, when the trigger assembly is triggered, the trigger assembly can rotate relative to the body; wherein the number of limiting assemblies is multiple, and the multiple limiting assemblies are centrally symmetric about the rotation axis of the trigger assembly.

[0057] In this technical solution, the number of limiting assemblies is limited to multiple, and since the limiting assemblies are arranged in the mounting holes, that is, the number of mounting holes is multiple.

[0058] Optionally, when the trigger assembly moves to the first position, at least one of the plurality of limiting assemblies limits the movement of the trigger assembly, so that the trigger assembly is fixed at the first position, and the air guide part is fixed at the first target position.

[0059] When the trigger assembly moves to the second position, at least one of the plurality of limiting assemblies limits the movement of the trigger assembly, so that the trigger assembly is fixed at the second position, and the air guide part is fixed at the second target position.

[0060] That is, when the trigger assembly moves to the first position and the second position, the limiting assembly limits the movement of the trigger assembly.

[0061] Optionally, when the trigger assembly moves to the first position, under the action of the pre-tightening force of the first elastic member, the first arm abuts against the first limiting wall, so that the trigger assembly is fixed at the first position, and the air guide part is fixed at the first target position.

[0062] When the trigger assembly moves to the second position, the plurality of limiting assemblies limit the movement of the trigger assembly, so that the trigger assembly can resist the elastic force of the first elastic member and be fixed at the second position, and the air guide part is fixed at the second target position.

[0063] The plurality of limiting assemblies are centrally symmetric about the rotation axis of the trigger assembly, so that when the trigger assembly is located at the second position and the plurality of limiting assemblies limit the movement of the trigger assembly, the trigger assembly can be balanced under force and keep the balance of force, so that the trigger assembly can resist the elastic force of the first elastic member, improve the limiting effect when the trigger assembly is located at the second position, and prolong the service life of the trigger assembly.

[0064] Optionally, the number of the grooves is also a plurality, and the plurality of grooves are arranged one-to-one corresponding to the plurality of limiting assemblies.

[0068] Optionally, a part of the first trigger is exposed outside the shell. That is, the first trigger is a rotary knob partially exposed outside the shell. In detail, when the user wants to change the blowing angle or blowing direction, the rotary knob is manually rotated, the rotary knob drives the second trigger to rotate, and the second trigger drives the air guide part to rotate to the first position.

[0069] When the user wants to change the blowing angle or blowing direction again, the rotary knob is manually reversely rotated, the rotary knob drives the second trigger to rotate, and the second trigger drives the air guide part to rotate to the second position.

[0070] Optionally, the trigger assembly further comprises a decorative cover connected to the end of the first trigger exposed outside the shell, so as to play a decorative role and improve the aesthetic property of the air outlet device.

[0072] Optionally, when the first trigger is triggered, the first trigger drives the second trigger to rotate by 90°, that is, drives the air guide part to rotate by 90° relative to the machine body to realize switching between the first position and the second position.

[0106] Moreover, by arranging the airflow generator in the air outlet device, the airflow speed can be accelerated, in the case that the air outlet device has a heating member, the heat generated by the heating member can be dissipated, the airflow speed can be effectively accelerated, the heat on the surface of the air outlet device can be quickly taken away, the temperature of the space to be heated can be quickly raised, and the comfort of the user in the space to be heated can be improved.

[0107] In addition, the air flow generator is arranged to accelerate the air flow, so that the heat on the surface of the air outlet device can be quickly taken away, the surface temperature of the air outlet device is effectively reduced, the linear power density of the heating element can be increased, and the heating efficiency and heating effect of the air outlet device are further improved.

[0108] In addition, by taking in air through one of the first air inlet and the second air inlet and taking out air through the other one, the structure of the air outlet device can be effectively simplified, the problem of excessive holes on the shell reducing the structural strength of the shell can be avoided, and the service life of the air outlet device can be ensured.

[0109] Optionally, the first air inlet is located on the side of the shell, and the second air inlet is located on the top of the shell. By moving the air guide part in the working cavity, the position of the air outlet part of the air guide part can be changed, and the air outlet of the side air inlet or the top air inlet can be controlled.

[0110] Optionally, when the trigger assembly is located at the first position, the air outlet part is opposite to the first air inlet, so that most of the air flow from the air outlet part flows out through the first air inlet, and the air outlet efficiency of the air flow is improved.

[0111] When the trigger assembly is located at the second position, the air outlet part is opposite to the second air inlet, so that most of the air flow from the air outlet part flows out through the second air inlet, and the air outlet efficiency of the air flow is improved.

[0115] In some technical solutions, the air outlet device further comprises a heating element. When the air guide part is arranged in the working cavity, at least a part of the heating element is located between the first air inlet and the air guide part, or at least a part of the heating element is located between the second air inlet and the air guide part. When the air guide part is arranged at the air outlet, the heating element is arranged between the first air inlet and the second air inlet; and / or the first air inlet and the second air inlet are respectively located on two sides of the working cavity.

[0116] In the technical solution, the air outlet device further comprises a heating element, and specifically, when the air guide part is arranged in the working cavity, i.e., the air guide part is a volute, at least a part of the heating element is located between the first air port and the air guide part, or at least a part of the heating element is located between the second air port and the air guide part. That is, at least a part of the heating element is located on the flow path of the air flow, so that the air flow generated by the air flow generating element can be fully heated before flowing out of the first air port or the second air port, thereby realizing the heating function of the air outlet device.

[0117] Specifically, at least a part of the heating element is located between the first air port and the air guide part, when the trigger assembly is located at the first position, the air outlet part is in communication with the first air port, the heating element is located between the air outlet part and the first air port, and the air inlet part is in communication with the second air port. The air flow enters the air duct in sequence through the second air port and the air inlet part, flows out through the air outlet part, and flows out through the first air port after being heated by the heating element.

[0118] When the trigger assembly is located at the second position, the air outlet part is in communication with the second air port, the heating element is located between the air inlet part and the first air port, and the air inlet part is in communication with the first air port. After the air flow enters the working cavity through the first air port, it flows through the heating element, enters the air duct through the air inlet part, flows out through the air outlet part, and then flows out through the second air port.

[0119] Alternatively, at least a part of the heating element is located between the second air port and the air guide part, when the trigger assembly is located at the first position, the air outlet part is in communication with the first air port, the heating element is located between the air inlet part and the second air port, and the air inlet part is in communication with the second air port. After the air flow enters the working cavity through the second air port, it flows through the heating element, enters the air duct through the air inlet part, flows out through the air outlet part, and then flows out through the first air port.

[0120] When the trigger assembly is located at the second position, the air outlet part is in communication with the second air port, the heating element is located between the air outlet part and the second air port, and the air inlet part is in communication with the first air port. The air flow enters the air duct in sequence through the first air port and the air inlet part, flows out through the air outlet part, and flows out through the second air port after being heated by the heating element.

[0121] In the case where the air guide part is arranged at the air outlet, i.e., the air guide part is an air guide plate, the air guide plate is arranged on the air port for air outlet among the first air port and the second air port, and by driving the air guide part to move through the trigger assembly, the air outlet angle can be changed.

[0122] The heating element is arranged between the first air port and the second air port, and it can be understood that one of the first air port and the second air port is used for air inlet, and the other is used for air outlet. The air flow is heated when flowing through the heating element, and then flows out through the air port for air outlet.

[0123] The first air outlet and the second air outlet are respectively located at two sides of the working cavity, so that the air outlet direction of the hot air flow can be changed by changing the position of the air outlet part of the air guide part, and a suitable air outlet of the air outlet can be selected according to the actual needs of the user, the flexibility and comfort of the user in using the air outlet device are improved, and the use experience of the user is improved.

[0124] Optionally, the first air outlet and the second air outlet are respectively located at two adjacent sides of the working cavity.

[0126] In this technical solution, the shell further comprises a third air outlet, specifically, the third air outlet is in communication with the working cavity, and the first air outlet and the third air outlet are located at two opposite sides of the working cavity, it can be understood that, in the case that the first air outlet is located at the front side of the shell, the third air outlet is located at the back side of the shell.

[0127] The shell further comprises a first edge and a second edge, wherein the first edge and the second edge are both located at the third air outlet, and the first edge is higher than the second edge in the height direction of the shell, that is, the first edge is a top edge, and the second edge is a bottom edge.

[0128] In the case that the air outlet part is in communication with the first air outlet, that is, in the case that the first air outlet is in air outlet, the edge of the air guide part at the air inlet part is higher than the first edge, so that air inlet at the third air outlet can be avoided, which is beneficial to ensure the heating effect of the air outlet device.

[0129] It can be understood that, since the heating element is arranged between the second air outlet and the air guide part, in the case that the first air outlet is in air outlet, if the air flow directly enters the air inlet part of the air guide part through the third air outlet and flows out through the air outlet part and the first air outlet, since the air flow entering the third air outlet is not heated by the heating element, the heating efficiency and heating effect of the air outlet device will be affected.

[0130] In the case that the air outlet part is in communication with the second air outlet, that is, in the case that the second air outlet is in air outlet, the third air outlet is in communication with the air inlet part, so that the air inlet amount of the air flow can be increased, and the heating efficiency and heating effect of the air outlet device can be improved.

[0138] In some embodiments, the distance d between the edge of the air inlet portion and the first edge of the air guide portion is 2mm≤d≤5mm when the air outlet portion is in communication with the first air port.

[0139] Optionally, in the case that the first air inlet and the second air outlet, the air inlet of the fourth air inlet is greater than the air inlet of the third air inlet, that is, the air inlet of the bottom is greater than the air inlet of the back, that is, the third air inlet is set to be smaller, so as to avoid the problem that the third air inlet is set to be larger, so that when the trigger assembly is located at the first position, the first edge is higher than the edge of the air inlet part of the air guide part, and then the third air inlet is inhaled, which further ensures the heating effect of the air outlet device.

[0140] Optionally, in the case that the first air inlet and the second air outlet, the air inlet of the first air inlet is smaller than the air inlet of the third air inlet due to the fact that the first air inlet is opposite to the outer wall of part of the air guide part.

[0141] In some technical solutions, the air outlet device further comprises a switch structure electrically connected with the heating element; wherein, based on the trigger assembly being located at the first position, the switch structure is turned on or off, and the heating element generates heat; and / or based on the trigger assembly being located at the second position, the switch structure is turned on or off, and the heating element generates heat.

[0142] In this technical solution, it is defined that the air outlet device further comprises a switch structure, and specifically, the switch structure is electrically connected with the heating element, when the trigger assembly is located at the first position, that is, the trigger assembly drives the air guide part to move, so that the air guide part moves to the first target position, the air outlet part is communicated with the first air inlet, the switch structure is turned on or off, and the heating element generates heat. And / or, when the trigger assembly is located at the second position, that is, the trigger assembly drives the air guide part to move, so that the air guide part moves to the second target position, the air outlet part is communicated with the second air inlet, the switch structure is turned on or off, and the heating element generates heat.

[0143] That is, when the trigger assembly drives the air guide part to move to change the position of the air outlet part, in the case that the air outlet part is not communicated or opposite to the first air inlet or the second air inlet, the state of the switch structure is controlled to make the heating element not work. And in the case that the trigger assembly drives the air guide part to move to the position, the heating element will start to work, so as to prevent the airflow from flowing disorderly, ensure the air outlet efficiency, and further improve the heat dissipation effect of the air outlet device.

[0146] That is, when the trigger assembly is triggered, the trigger assembly drives the air guide portion to rotate relative to the shell, and the rotating shaft rotates in the wear-resistant sleeve to adjust the position of the air outlet of the air guide portion, thereby controlling the air outlet direction.

[0147] By arranging the wear-resistant sleeve, the wear during rotation of the rotating shaft can be reduced, and the service life of the air outlet device is prolonged.

[0151] The control method of the air guide structure provided by the present application, in particular, the air guide structure comprises a limiting piece, a limiting groove, a trigger assembly and an air guide portion, the trigger assembly is connected with the limiting piece and the air guide portion, that is, when the trigger assembly is triggered, the trigger assembly drives at least part of the air guide portion to move relative to the shell, and at least part of the limiting piece also moves in the limiting groove.

[0152] Since the trigger assembly drives the air guide portion to move relative to the shell, the flow direction of the gas at the air outlet can be changed, so that the user can adjust the air supply angle or air supply direction according to actual needs, which is beneficial to improve the flexibility and comfort of the user in using the air outlet device, and thus improve the user experience.

[0153] Moreover, since at least part of the limiting piece moves in the limiting groove, the movement range of the trigger assembly can be limited, thereby limiting the movement range of the air guide portion, and thus the air outlet device can supply air at a set air supply angle, the control process is simplified, the air supply angle or air supply direction is accurately adjusted, and the air outlet effect is ensured.

[0154] Optionally, the air guide portion comprises an air guide plate arranged at the air outlet, and in the case that the trigger assembly is triggered, the air supply angle at the air outlet can be adjusted by moving the air guide plate relative to the shell.

[0155] Optionally, the air guide part comprises a volute, the volute has an air outlet part, the air outlet comprises a first air outlet and a second air outlet, and the air outlet part can be communicated with the first air outlet or the second air outlet by moving the volute relative to the shell, that is, the air outlet of the suitable air outlet can be selected according to actual needs to adjust the air supply direction.

[0156] In addition, the control method of the air guide structure provided by the above technical scheme of the application also has the following additional technical features:

[0157] In some technical solutions, the air outlet comprises a first air outlet and a second air outlet, the air guide part is provided with an air outlet part, and the control trigger assembly is triggered, specifically including: rotating the control trigger assembly in a first direction, and in the case that the trigger assembly is located at a first position, the air outlet part is communicated with the first air outlet; or rotating the control trigger assembly in a second direction, and in the case that the trigger assembly is located at a second position, the air outlet part is communicated with the second air outlet, and the second direction is different from the first direction.

[0158] In this technical solution, the air outlet comprises a first air outlet and a second air outlet, and optionally, the first air outlet and the second air outlet are located on both sides of the working cavity. Optionally, the first air outlet and the second air outlet are located on two adjacent sides of the working cavity.

[0159] Specifically, when the trigger assembly is rotated to the first position, the trigger assembly drives the air guide part to rotate to a first target position, and the air outlet part is communicated with the first air outlet, that is, the first air outlet is out of air.

[0160] When the trigger assembly is reversely rotated to the second position, the trigger assembly drives the air guide part to rotate to a second target position, and the air outlet part is communicated with the second air outlet, that is, the second air outlet is out of air.

[0161] That is, by controlling the forward or reverse movement of the trigger assembly, the position of the air outlet part of the air guide part can be changed, and then the first air outlet or the second air outlet can be controlled to be out of air, that is, the air outlet direction can be controlled, so that the suitable air outlet can be selected according to the actual needs of the user, the flexibility and comfort of the user in using the air outlet device are improved, and the user experience is improved.

[0163] In the technical solution, when the trigger assembly is located at the first position, the first elastic member is deformed, so that the first arm abuts against the first limiting wall, thereby keeping the trigger assembly at the first position, and further keeping the air guide part at the first target position, to realize fixation of one of the air supply angles or air supply directions, and to ensure stable air outflow in the air supply angle or air supply direction.

[0164] When it is necessary to adjust the air supply angle or air supply direction, the trigger assembly is triggered and moves from the first position to the second position, the deformation amount of the first elastic member is increased, the positioning part is inserted into the groove of the trigger assembly to limit movement of the trigger assembly, so that the trigger assembly is kept at the second position, and further keeps the air guide part at the second target position, to realize fixation of the other air supply angle or air supply direction, and to ensure stable air outflow in the air supply angle or air supply direction.

[0165] That is, the pre-tightening force of the first elastic member is used to realize fixation of one state, and the limiting assembly is used to realize fixation of the other state, that is, one limiting assembly and the first elastic member can realize fixation of two states, which is beneficial to simplify the structure of the air outflow device.

[0196] The body 110 further includes the first limiting wall 112 and the second limiting wall 113, wherein the first limiting wall 112 and the second limiting wall 113 are located in the limiting slot 111, and along the movement direction of the first arm 122 in the limiting slot 111, the first limiting wall 112 and the second limiting wall 113 are respectively located on both sides of the first arm 122, thereby indirectly limiting the movement range of the air guide part 140 through the trigger assembly 130, simplifying the operation process, realizing the rapid adjustment of the air supply angle or the air supply direction, and ensuring the air outlet effect.

[0197] Specifically, when the trigger assembly 130 is triggered, the trigger assembly 130 drives the first arm 122 to move in the limiting slot 111 along a first direction, at the same time, the trigger assembly 130 drives the air guide part 140 to move along the first direction, when the first arm 122 abuts against the first limiting wall 112, the trigger assembly 130 cannot continue to move, so that the air guide part 140 cannot continue to move, thereby indirectly prompting the user to move to the position.

[0198] When the trigger assembly 130 is triggered in reverse, the trigger assembly 130 drives the first arm 122 to move in the limiting slot 111 along a second direction, at the same time, the trigger assembly 130 drives the air guide part 140 to move along the second direction, when the first arm 122 abuts against the second limiting wall 113, the trigger assembly 130 cannot continue to move, so that the air guide part 140 cannot continue to move, thereby indirectly prompting the user to move to the position, and improving the user operation experience.

[0199] Wherein, the first direction is opposite to the second direction.

[0200] As Figure 1 andFigure 2 As shown, in some embodiments, optionally, the limiting piece 120 comprises a first elastic piece 121 provided with a first arm 122, the trigger assembly 130 is capable of moving between the first position and the second position; based on the trigger assembly 130 being located at the first position, the first elastic piece 121 has a deformation to make the first arm 122 abut against the first limiting wall 112; and / or based on the trigger assembly 130 being located at the second position, the first elastic piece 121 has a deformation to make the first arm 122 abut against the second limiting wall 113.

[0201] In this embodiment, the limiting piece 120 is defined as the first elastic piece 121, specifically, when the trigger assembly 130 moves to the first position, the air guide part 140 is located at the first target position, the first elastic piece 121 has a deformation to make the first arm 122 abut against the first limiting wall 112, that is to say, the first elastic piece 121 has a certain pre-tightening force, so that the first arm 122 can abut against the first limiting wall 112, so that the air guide part 140 can be temporarily fixed at the first target position, ensuring that the air outlet device 200 can stably blow air according to the adjusted set air supply angle or air supply direction, improving the air supply effect, and being beneficial to improving the comfort of the user using the air outlet device 200.

[0202] And / or, when the trigger assembly 130 is located at the second position, the air guide part 140 is located at the second target position, the first elastic piece 121 has a deformation to make the first arm 122 abut against the second limiting wall 113, that is to say, the first elastic piece 121 has a certain pre-tightening force, so that the first arm 122 can abut against the second limiting wall 113, so that the air guide part 140 can be temporarily fixed at the second target position, ensuring that the air outlet device 200 can stably blow air according to the adjusted set air supply angle or air supply direction.

[0203] Moreover, when the trigger assembly 130 moves to the first position or the second position, no additional fixing device is needed to fix the trigger assembly 130 or the air guide part 140, which is beneficial to simplify the structure of the air outlet device 200, optimize the overall layout of the air outlet device 200, reduce the number of parts, and further reduce the production cost of the air outlet device 200.

[0204] In some embodiments, optionally, when the trigger assembly 130 is located at the first position and the first elastic piece 121 has a deformation to make the first arm 122 abut against the first limiting wall 112, the first elastic piece 121 has a first deformation amount; when the trigger assembly 130 is located at the second position, the first elastic piece 121 has a second deformation amount, the second deformation amount being greater than the first deformation amount.

[0205] In this embodiment, when the trigger assembly 130 is located at the first position, the first elastic member 121 has a certain deformation amount, so that the trigger assembly 130 can be temporarily fixed at the first position without other fixing devices, thereby temporarily fixing the air guide part 140 at the first target position, ensuring that the air supply direction or the air supply angle can be stably set.

[0206] When it is necessary to adjust the air supply angle or the air supply direction, the trigger assembly 130 is triggered, the trigger assembly 130 moves from the first position to the second position, and when the trigger assembly 130 moves to the second position, the deformation amount of the first elastic member 121 increases, so that when it is necessary to adjust the air supply angle or the air supply direction again, the elastic force of the first elastic member 121 can drive the trigger assembly 130 to automatically reset from the second position to the first position, further simplifying the operation process when adjusting the air supply angle or the air supply direction, and improving the operation experience of the user.

[0207] As shown in Figure 4 In some embodiments, optionally, the body 110 is further provided with a first mounting groove 114; the first elastic member 121 further includes a second arm 123, the second arm 123 and the first arm 122 are respectively located at two ends of the first elastic member 121, and the second arm 123 is arranged in the first mounting groove 114.

[0208] In this embodiment, it is limited that the first elastic member 121 further includes the second arm 123, specifically, the second arm 123 and the first arm 122 are respectively located at two ends of the first elastic member 121.

[0209] The body 110 is further provided with the first mounting groove 114, and the second arm 123 is arranged in the first mounting groove 114, that is, the second arm 123 is fixed in the first mounting groove 114, so that when the trigger assembly 130 drives the first arm 122 to move in the limiting groove 111, the deformation amount of the first elastic member 121 can be changed.

[0210] Optionally, the first elastic member 121 includes a torsion spring.

[0211] Optionally, the length of the first arm 122 is greater than the length of the second arm 123, that is, the first arm 122 is a long arm, and the second arm 123 is a short arm.

[0212] As shown in Figure 1 and Figure 4As shown in some embodiments, the body 110 is optionally provided with a mounting shaft 115, which is rotationally connected with the trigger assembly 130, and the trigger assembly 130 is capable of rotating relative to the mounting shaft 115 when the trigger assembly 130 is triggered; wherein an outer wall of the mounting shaft 115 is provided with a second mounting groove 116, which is in communication with the limiting groove 111, and the first elastic member 121 is sleeved on the mounting shaft 115 and at least partially embedded in the second mounting groove 116.

[0213] In this embodiment, it is defined that the body 110 is further provided with a mounting shaft 115, specifically, the mounting shaft 115 is rotationally connected with the trigger assembly 130, that is, when the trigger assembly 130 is triggered, the trigger assembly 130 drives the first arm 122 and the air guide part 140 to rotate relative to the mounting shaft 115.

[0214] The outer wall of the mounting shaft 115 is provided with a second mounting groove 116, which is in communication with the limiting groove 111, and the first elastic member 121 is sleeved on the mounting shaft 115, and at least a part of the first elastic member 121 is embedded in the second mounting groove 116, so as to improve the installation stability and reliability of the first elastic member 121, and further ensure the smooth and stable adjustment of the air supply angle or air supply direction.

[0215] In addition, since at least a part of the first elastic member 121 is embedded in the second mounting groove 116, it is beneficial to reduce the thickness of the air guide structure 100 in the axial direction of the mounting shaft 115, and further reduce the occupied space of the air guide structure 100 in the air outlet device 200, which is beneficial to realize the miniaturization of the air outlet device 200.

[0216] Optionally, the second mounting groove 116 is in communication with the first mounting groove 114.

[0217] As shown in some embodiments, the body 110 is optionally provided with a mounting shaft 115, which is rotationally connected with the trigger assembly 130, and the trigger assembly 130 is capable of rotating relative to the mounting shaft 115 when the trigger assembly 130 is triggered; wherein an outer wall of the mounting shaft 115 is provided with a second mounting groove 116, which is in communication with the limiting groove 111, and the first elastic member 121 is sleeved on the mounting shaft 115 and at least partially embedded in the second mounting groove 116. Figure 2 、 Figure 3 and Figure 6 As shown in some embodiments, the trigger assembly 130 is provided with a clamping groove 131, and a part of the first arm 122 is embedded in the clamping groove 131, so as to connect the first arm 122 with the trigger assembly 130.

[0218] In this embodiment, the trigger assembly 130 is provided with a clamping groove 131, specifically, the clamping groove 131 is located on the side of the trigger assembly 130 facing the first elastic member 121. A part of the first arm 122 is embedded in the clamping groove 131, so that the first arm 122 is connected with the trigger assembly 130, so that when the trigger assembly 130 is triggered, the trigger assembly 130 can drive the first arm 122 to move in the limiting groove 111, so as to limit the movement range of the trigger assembly 130, and further limit the movement range of the air guide part 140, so that the air outlet device 200 can blow air according to the set air outlet angle, simplify the operation process, realize the rapid adjustment of the air outlet angle or the air outlet direction, and ensure the air outlet effect.

[0219] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , in some embodiments, optionally, the air guide structure 100 further comprises a limiting assembly 150, which is arranged on at least one of the body 110 and the trigger assembly 130; wherein, based on the trigger assembly 130 being located at the first position, the limiting assembly 150 can limit the trigger assembly 130 in the movement direction of the trigger assembly 130; and / or based on the trigger assembly 130 being located at the second position, the limiting assembly 150 can limit the trigger assembly 130 in the movement direction of the trigger assembly 130.

[0220] In this embodiment, the air guide structure 100 further comprises a limiting assembly 150, specifically, the limiting assembly 150 is arranged on at least one of the body 110 and the trigger assembly 130. Specifically, the limiting assembly 150 is arranged on the body 110. Alternatively, the limiting assembly 150 is arranged on the trigger assembly 130. Alternatively, part of the limiting assembly 150 is arranged on the body 110, and the other part is arranged on the trigger assembly 130. Specifically, it can be arranged according to actual needs.

[0221] When the trigger assembly 130 moves to the first position, the air guide part 140 moves to the first target position under the driving of the trigger assembly 130, and the limiting assembly 150 can limit the trigger assembly 130 in the movement direction of the trigger assembly 130, that is, the limiting assembly 150 can keep the trigger assembly 130 at the first position, thereby indirectly keeping the air guide part 140 at the first target position, which is beneficial to ensure that the air outlet device 200 can stably blow air according to the adjusted air outlet angle or air outlet direction.

[0222] When the trigger assembly 130 is moved to the second position, the air guide part 140 is moved to the second target position under the action of the trigger assembly 130, and the limiting assembly 150 can limit the movement of the trigger assembly 130 in the movement direction of the trigger assembly 130, i.e., the limiting assembly 150 can keep the trigger assembly 130 in the second position, thereby indirectly keeping the air guide part 140 in the second target position, which is beneficial to ensuring that the air outlet device 200 can stably blow air according to the adjusted blowing angle or blowing direction.

[0223] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , in some embodiments, the body 110 is further provided with a mounting hole 117, the trigger assembly 130 is provided with a groove 132, and the limiting assembly 150 comprises a second elastic member 151 and a positioning part 152, wherein the second elastic member 151 is arranged in the mounting hole 117, the positioning part 152 is connected with the second elastic member 151 and at least partially exposed outside the mounting hole 117, and the positioning part 152 can move in the mounting hole 117 to move into or out of the groove 132.

[0224] In this embodiment, it is defined that the limiting assembly 150 comprises the second elastic member 151 and the positioning part 152, specifically, the body 110 is further provided with the mounting hole 117, the second elastic member 151 is arranged in the mounting hole 117, and the positioning part 152 is connected with the second elastic member 151 and at least partially exposed outside the mounting hole 117.

[0225] The positioning part 152 can move in the mounting hole 117 to move into or out of the groove 132. Specifically, when the trigger assembly 130 drives the air guide part 140 to move from the first position to the second position, or when the trigger assembly 130 drives the air guide part 140 to move from the second position to the first position, the part of the positioning part 152 exposed outside the mounting hole 117 is in contact with the position where the groove 132 is located, the positioning part 152 is forced to move into the mounting hole 117, and the second elastic member 151 is deformed, when the groove 132 is opposite to the positioning part 152, the positioning part 152 is inserted into the groove 132 under the action of the elastic force of the second elastic member 151, so that the trigger assembly 130 is fixed in the second position or the first position, thereby making the air guide part 140 fixed in the second target position or the first target position.

[0226] It can be understood that when it is necessary to adjust the blowing angle or blowing direction, the trigger assembly 130 is triggered again, and the positioning part 152 is moved out of the groove 132 to release the movement limitation of the trigger assembly 130.

[0227] Optionally, when the trigger assembly 130 is located at the first position, the first elastic member 121 is deformed so that the first arm 122 abuts against the first limiting wall 112, thereby keeping the trigger assembly 130 at the first position, and further keeping the air guide portion 140 at the first target position, so as to fix one of the blowing angles or directions and ensure stable air outflow in the blowing angle or direction.

[0228] When it is necessary to adjust the blowing angle or direction, the trigger assembly 130 is triggered and moves from the first position to the second position, the deformation amount of the first elastic member 121 is increased, the positioning portion 152 is inserted into the groove 132 of the trigger assembly 130 to limit the movement of the trigger assembly 130, so as to keep the trigger assembly 130 at the second position, and further keep the air guide portion 140 at the second target position, so as to fix the other blowing angle or direction and ensure stable air outflow in the blowing angle or direction.

[0229] That is, the pre-tightening force of the first elastic member 121 is used to fix one state, and the limiting assembly 150 is used to fix the other state, that is, one limiting assembly 150 and the first elastic member 121 can be used to fix two states, which is conducive to simplifying the structure of the air outflow device 200.

[0230] Moreover, compared with the related art in which a micro switch is used to control whether the heating element 230 generates heat in the two states, and further to perceive whether the trigger assembly 130 is moved to the position, that is, one limiting assembly 150 and the first elastic member 121 can be used to perceive two states, and the micro switch structure 240 is omitted, which is conducive to further simplifying the structure of the air outflow device 200 and reducing the production cost of the air outflow device 200.

[0231] Optionally, the number of the limiting assemblies 150 is two, when the trigger assembly 130 is located at the first position, the positioning portion 152 is inserted into the groove 132 of the trigger assembly 130 to limit the movement of the trigger assembly 130, so as to keep the trigger assembly 130 at the first position.

[0232] When it is necessary to adjust the blowing angle or direction, the trigger assembly 130 is triggered again, the positioning portion 152 is moved out of the groove 132, and when the trigger assembly 130 moves to the second position, the other positioning portion 152 is inserted into the other groove 132 of the trigger assembly 130 to limit the movement of the trigger assembly 130, so as to keep the trigger assembly 130 at the second position.

[0233] It can be understood that when the positioning portion 152 is inserted into the groove 132, a "tick" sound is generated, so that the user can intuitively perceive the two states of the movement of the trigger assembly 130, and further indirectly know whether the air guide portion 140 is moved to the position, thereby improving the operation experience of the user.

[0234] Optionally, the second elastic member 151 includes a spring.

[0235] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, optionally, when the trigger assembly 130 is triggered, the trigger assembly 130 can rotate relative to the body 110; wherein, there are multiple limit assemblies 150, and the multiple limit assemblies 150 are symmetrical about the rotation axis of the trigger assembly 130.

[0236] In this embodiment, the number of the limiting components 150 is limited to plural, because the limiting components 150 are arranged in the mounting holes 117, that is, the number of the mounting holes 117 is plural.

[0237] Optionally, when the trigger assembly 130 moves to the first position, at least one of the plurality of limiting assemblies 150 limits the movement of the trigger assembly 130 so that the trigger assembly 130 is fixed in the first position, thereby fixing the air guide portion 140 in the first target position.

[0238] When the trigger assembly 130 moves to the second position, at least one of the plurality of limiting assemblies 150 limits the movement of the trigger assembly 130 so that the trigger assembly 130 is fixed at the second position, thereby fixing the air guide portion 140 at the second target position.

[0239] That is, when the trigger assembly 130 moves to the first position and the second position, the limiting assembly 150 is provided to limit the movement of the trigger assembly 130 .

[0240] Optionally, when the trigger assembly 130 moves to the first position, under the action of the preload force of the first elastic member 121, the first arm 122 abuts against the first limiting wall 112, thereby fixing the trigger assembly 130 in the first position, and further fixing the air guide portion 140 in the first target position.

[0241] When the trigger assembly 130 moves to the second position, multiple limit assemblies 150 limit the movement of the trigger assembly 130, so that the trigger assembly 130 can resist the elastic force of the first elastic member 121 and be fixed in the second position, thereby fixing the air guide portion 140 at the second target position.

[0242] The plurality of limiting assemblies 150 are centrally symmetric about the rotation axis of the trigger assembly 130, so that when the plurality of limiting assemblies 150 limit the movement of the trigger assembly 130 when the trigger assembly 130 is in the second position, the trigger assembly 130 can be balanced and the balance of force can be maintained, so that the trigger assembly 130 can resist the elastic force of the first elastic member 121, improve the limiting effect when the trigger assembly 130 is in the second position, and prolong the service life of the trigger assembly 130.

[0243] Optionally, the number of the grooves 132 is also a plurality, and the plurality of grooves 132 are arranged one-to-one with the plurality of limiting assemblies 150.

[0245] In this embodiment, it is defined that the trigger assembly 130 further includes the first trigger member 133 and the second trigger member 134, specifically, the second trigger member 134 is located on the side of the first trigger member 133 close to the machine body 110, and the second trigger member 134 is connected with the limiting member 120 and the first trigger member 133.

[0246] Specifically, when the first trigger member 133 is triggered, the first trigger member 133 drives the second trigger member 134 to rotate, the second trigger member 134 drives at least part of the limiting member 120 to move in the limiting groove 111, and at the same time, the second trigger member 134 drives the air guide part 140 to rotate relative to the machine body 110, so as to change the blowing angle or blowing direction of the air supply device 200.

[0247] Optionally, a part of the first trigger member 133 is exposed outside the shell 210. That is, the first trigger member 133 is a knob partially exposed outside the shell 210. In detail, when the user wants to change the blowing angle or blowing direction, the knob is manually rotated, the knob drives the second trigger member 134 to rotate, and the second trigger member 134 drives the air guide part 140 to rotate to the first position.

[0248] When the user wants to change the blowing angle or blowing direction again, the knob is manually rotated in the reverse direction, the knob drives the second trigger member 134 to rotate, and the second trigger member 134 drives the air guide part 140 to rotate to the second position.

[0249] Optionally, the triggering assembly 130 further comprises a decorative cover connected to the end of the first triggering piece 133 exposed from the shell 210, so as to play a decorative role and improve the appearance of the air outlet device 200.

[0250] It can be understood that the recess 132 and the clamping slot 131 are arranged on the side of the second triggering piece 134 facing the machine body 110.

[0251] Optionally, when the first triggering piece 133 is triggered, the first triggering piece 133 drives the second triggering piece 134 to rotate by 90°, i.e. drives the air guide part 140 to rotate by 90° relative to the machine body 110, so as to realize switching between the first position and the second position.

[0253] In this embodiment, it is defined that the machine body 110 comprises the support frame 118 and the mounting seat 119, specifically, the air guide part 140 and the triggering assembly 130 are respectively located on two sides of the support frame 118, and the support frame 118 is provided with the avoiding opening 160.

[0254] The air guide part 140 is provided with the first connecting column 141, and the triggering assembly 130 is provided with the second connecting column 135, specifically, the first connecting column 141 passes through the avoiding opening 160 and is connected with the second connecting column 135, so that the triggering assembly 130 can drive the air guide part 140 to move in the case of being triggered.

[0255] Alternatively, the second connecting column 135 passes through the avoiding opening 160 and is connected with the first connecting column 141, so that the triggering assembly 130 can drive the air guide part 140 to move in the case of being triggered. Specifically, it can be arranged according to actual needs.

[0256] Optionally, the support frame 118 is fixed on the inner wall of the shell 210.

That is to say, when the triggering assembly 130 is triggered, the triggering assembly 130 can move relative to the mounting seat 119.

[0259] It can be understood that the mounting hole 117 is arranged on the mounting seat 119. The mounting shaft 115, the first mounting groove 114 and the second mounting groove 116 are all arranged on the mounting seat 119.

[0260] Optionally, the second triggering member 134 is provided with a rotating hole, and the mounting shaft 115 on the mounting seat 119 penetrates through the rotating hole and is rotationally connected with the second triggering member 134, so that when the first triggering member 133 is triggered, the first triggering member 133 drives the second triggering member 134 to rotate relative to the mounting seat 119, and at the same time, the second triggering member 134 drives the air guiding part 140 to rotate relative to the machine body 110.

That is to say, the air guide part 140 is a volute.

[0276] Optionally, the airflow generating member 220 comprises a fan wheel 222 and a driving member 221, the fan wheel 222 is connected with the driving member 221, that is to say, under the driving of the driving member 221, the fan wheel 222 rotates in the air duct 142 to generate airflow, after the airflow passes through the air duct 142, it flows out through the air outlet part 144, the air guide part 140 is moved in the working cavity 212 by the trigger assembly 130 to change the position of the air outlet part 144, thereby realizing the change of the flowing direction of the air outlet airflow.

[0277] Optionally, the driving member 221 is arranged on the support frame 118 and connected with the fan wheel 222 through the avoiding opening 160 of the support frame 118.

Optionally, the first air outlet 213 and the second air outlet 214 are located on two adjacent sides of the working cavity 212.

[0280] Since the air flow generator 220 is arranged in the air duct 142, it can be understood that the air flow generator 220 can generate air flow in working condition. Optionally, the air outlet device 200 further comprises a heating element 230 arranged in the working cavity 212, that is, the air flow generated by the air flow generator 220 is heated by the heating element 230 after flowing out of the air outlet part 144 and then flows out through the first air port 213 or the second air port 214.

[0281] Specifically, when the trigger assembly 130 is located at the first position, the trigger assembly 130 drives the air guide part 140 to move to the first target position, the air outlet part 144 is in communication with the first air port 213, and the air inlet part 143 is in communication with the second air port 214, that is, the first air port 213 is in air outlet condition, and the second air port 214 is in air inlet condition.

[0284] Moreover, by arranging the air flow generator 220 in the air outlet device 200, the air flow speed can be accelerated, and in the case that the air outlet device 200 has the heating element 230, the heat generated by the heating element 230 can be dissipated, which can effectively accelerate the air flow speed, quickly remove the heat on the surface of the air outlet device 200, and rapidly increase the temperature of the space to be heated, thereby improving the comfort of the user in the space to be heated.

[0285] In addition, since the air flow generator 220 is arranged to accelerate the air flow, the heat on the surface of the air outlet device 200 can be quickly removed, thereby effectively reducing the surface temperature of the air outlet device 200, so that the line power density of the heating element 230 can be improved, and the heating efficiency and heating effect of the air outlet device 200 can be further improved.

[0286] In addition, by making one of the first air port 213 and the second air port 214 in air inlet condition and the other in air outlet condition, the structure of the air outlet device 200 can be effectively simplified, and the problem of reducing the structural strength of the shell 210 due to too many holes in the shell 210 can be avoided, thereby ensuring the service life of the air outlet device 200.

[0289] When the trigger assembly 130 is located at the second position, the air outlet part 144 is opposite to the second air outlet 214, so that most of the air flow from the air outlet part 144 flows out through the second air outlet 214, and the air outlet efficiency of the air flow is improved.

[0290] Optionally, the air outlet device 200 further comprises a touch control panel, which is arranged on the housing 210 and partially exposed to the outside of the housing 210.

The first end plate is mounted on the motor mounting bracket by the gland, and the first end plate can rotate relative to the motor mounting bracket.

[0293] As shown in FIGS. Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , in some embodiments, the air outlet device 200 further comprises a heating part 230. When the air guide part 140 is arranged in the working cavity 212, at least a part of the heating part 230 is located between the first air outlet 213 and the air guide part 140, or at least a part of the heating part 230 is located between the second air outlet 214 and the air guide part 140. When the air guide part 140 is arranged at the air outlet 211, the heating part 230 is arranged between the first air outlet 213 and the second air outlet 214; and / or the first air outlet 213 and the second air outlet 214 are respectively located at two sides of the working cavity 212.

[0294] In this embodiment, the air outlet device 200 further comprises a heating element 230, and specifically, at least a portion of the heating element 230 is located between the first air outlet 213 and the air guide portion 140 when the air guide portion 140 is arranged in the working cavity 212, i.e., the air guide portion 140 is a volute, or at least a portion of the heating element 230 is located between the second air outlet 214 and the air guide portion 140. That is, at least a portion of the heating element 230 is located on the flow path of the airflow, so that the airflow generated by the airflow generating element 220 can be sufficiently heated before flowing out of the first air outlet 213 or the second air outlet 214, thereby realizing the heating function of the air outlet device 200.

[0295] Specifically, at least a portion of the heating element 230 is located between the first air outlet 213 and the air guide portion 140, when the trigger assembly 130 is located at the first position, the air outlet portion 144 is in communication with the first air outlet 213, the heating element 230 is located between the air outlet portion 144 and the first air outlet 213, and the air inlet portion 143 is in communication with the second air outlet 214. The airflow enters the air duct 142 in sequence through the second air outlet 214 and the air inlet portion 143, flows out through the air outlet portion 144, and is heated by flowing through the heating element 230 before flowing out through the first air outlet 213.

[0296] When the trigger assembly is located at the second position, the air outlet portion 144 is in communication with the second air outlet 214, the heating element 230 is located between the air inlet portion 143 and the first air outlet 213, and the air inlet portion 143 is in communication with the first air outlet 213. After the airflow enters the working cavity 212 through the first air outlet 213, it is heated by flowing through the heating element 230 before entering the air duct 142 through the air inlet portion 143, and then flows out through the second air outlet 214 after flowing out through the air outlet portion 144.

[0297] Alternatively, at least a portion of the heating element 230 is located between the second air outlet 214 and the air guide portion 140, when the trigger assembly 130 is located at the first position, the air outlet portion 144 is in communication with the first air outlet 213, the heating element 230 is located between the air inlet portion 143 and the second air outlet 214, and the air inlet portion 143 is in communication with the second air outlet 214. After the airflow enters the working cavity 212 through the second air outlet 214, it is heated by flowing through the heating element 230 before entering the air duct 142 through the air inlet portion 143, and then flows out through the first air outlet 213 after flowing out through the air outlet portion 144.

[0298] When the trigger assembly 130 is located at the second position, the air outlet portion 144 is in communication with the second air outlet 214, the heating element 230 is located between the air outlet portion 144 and the second air outlet 214, and the air inlet portion 143 is in communication with the first air outlet 213. The airflow enters the air duct 142 in sequence through the first air outlet 213 and the air inlet portion 143, flows out through the air outlet portion 144, and is heated by flowing through the heating element 230 before flowing out through the second air outlet 214.

[0299] In the case that the air guide part 140 is arranged at the air outlet 211, that is, the air guide part 140 is an air guide plate, the air guide plate is arranged on the air outlet for air outlet among the first air outlet 213 and the second air outlet 214, and the air guide part 140 is driven to move by the triggering assembly 130, so that the air outlet angle can be changed.

[0300] The heating element 230 is arranged between the first air outlet 213 and the second air outlet 214. It can be understood that one of the first air outlet 213 and the second air outlet 214 is used for air inlet, and the other is used for air outlet. The airflow is heated when flowing through the heating element 230 and flows out through the air outlet for air outlet.

[0301] The first air outlet 213 and the second air outlet 214 are respectively located on two sides of the working cavity 212, so that the air outlet direction of the hot airflow can be changed by changing the position of the air outlet part 144 of the air guide part 140. The user can select a suitable air outlet according to the actual needs, improve the flexibility and comfort of the user in using the air outlet device 200, and further improve the user experience.

[0302] Optionally, the first air outlet 213 and the second air outlet 214 are respectively located on two adjacent sides of the working cavity 212.

[0303] As shown in Figure 11 and Figure 12 In some embodiments, optionally, in the case that at least a part of the heating element 230 is located between the second air outlet 214 and the air guide part 140, the shell 210 further comprises a third air outlet 215, the third air outlet 215 is in communication with the working cavity 212, and the first air outlet 213 and the third air outlet 215 are respectively located on two opposite sides of the working cavity 212; the shell 210 further comprises a first edge 217 and a second edge 218 located at the third air outlet 215 and opposite to each other, the first edge 217 is closer to the top of the shell 210 than the second edge 218 in the height direction of the shell 210; wherein, in the case that the air outlet part is in communication with the first air outlet 213, the edge of the air guide part 140 located at the air inlet part is higher than the first edge 217; in the case that the air outlet part is in communication with the second air outlet 214, the third air outlet 215 is in communication with the air inlet part.

[0304] In this embodiment, it is defined that the shell 210 further comprises a third air outlet 215, specifically, the third air outlet 215 is in communication with the working cavity 212, and the first air outlet 213 and the third air outlet 215 are respectively located on two opposite sides of the working cavity 212. It can be understood that in the case that the first air outlet 213 is located on the front side of the shell 210, the third air outlet 215 is located on the back side of the shell 210.

[0305] The shell 210 also includes a first edge 217 and a second edge 218, wherein the first edge 217 and the second edge 218 are both located at the third air outlet 215, and along the height direction of the shell 210, the first edge 217 is higher than the second edge 218, that is, the first edge 217 is the top edge and the second edge 218 is the bottom edge.

[0306] When the air outlet is connected to the first air port 213, that is, when air is discharged from the first air port 213, the edge of the air guide portion 140 at the air inlet is higher than the first edge 217, thereby avoiding air from entering the third air port 215, which is beneficial to ensuring the heating effect of the air outlet device 200.

[0307] It can be understood that since the heating element 230 is arranged between the second air outlet 214 and the air guide portion 140, when air is discharged from the first air outlet 213, if the air flow directly enters the air inlet of the air guide portion 140 through the third air outlet 215, and flows out through the air outlet and the first air outlet 213, since the air flow entering from the third air outlet 215 is not heated by the heating element 230, it will affect the heating efficiency and heating effect of the air outlet device 200.

[0308] When the air outlet is connected to the second air port 214 , that is, when the second air port 214 is discharging air, the third air port 215 is connected to the air inlet, thereby increasing the air intake volume and improving the heating efficiency and heating effect of the air outlet device 200 .

[0309] like Figure 11 As shown, in some embodiments, optionally, when the air outlet is connected to the first air port 213, the distance d between the edge of the air guide 140 located at the air inlet and the first edge 217 satisfies 2mm≤d≤5mm.

[0310] In this embodiment, when the air outlet is connected to the first air port 213, that is, when air is discharged from the first air port 213, the distance between the edge of the air guide portion 140 at the air inlet and the first edge 217 is between 2 mm and 5 mm, which can be determined based on the processing accuracy and deformation degree of the components.

[0311] That is to say, since the heating element 230 is arranged between the second air outlet 214 and the air guide portion 140, when the trigger assembly 130 is in the first position, the distance between the edge of the air guide portion 140 at the air inlet and the first edge 217 is small, so that when air is discharged from the first air outlet 213, the air intake at the third air outlet 215 is further reduced, thereby ensuring the heating effect of the air outlet device 200.

[0312] like Figure 11 and Figure 12As shown, in some embodiments, optionally, in the case that at least a part of the heating element 230 is located between the second air outlet 214 and the air guide portion 140, the shell 210 is further provided with a fourth air outlet 216, which is in communication with the working cavity 212 and is located on the opposite side of the working cavity 212 from the second air outlet 214; wherein, in the case that the air outlet portion is in communication with the first air outlet 213, the fourth air outlet 216 is opposite to the outer wall of the air guide portion 140 in the height direction of the shell 210; in the case that the air outlet portion is in communication with the second air outlet 214, the fourth air outlet 216 is in communication with the air inlet portion.

[0313] In this embodiment, it is defined that the shell 210 is further provided with a fourth air outlet 216, specifically, the fourth air outlet 216 is in communication with the working cavity 212, and the fourth air outlet 216 and the second air outlet 214 are located on opposite sides of the working cavity 212, respectively. It can be understood that, in the case that the second air outlet 214 is located at the top of the shell 210, the fourth air outlet 216 is located at the bottom of the shell 210.

[0314] Since at least a part of the heating element 230 is located between the second air outlet 214 and the air guide portion 140, in the case that the air outlet portion is in communication with the first air outlet 213, i.e. in the case that the first air outlet 213 is air outlet, the fourth air outlet 216 is opposite to the outer wall of the air guide portion 140 in the height direction of the shell 210, so that air inlet at the fourth air outlet 216 can be avoided, further ensuring the heating effect of the air outlet device 200.

[0315] In detail, in the case that the first air outlet 213 is air outlet, if the airflow enters the air duct 142 through the fourth air outlet 216, or the airflow enters the working cavity 212 through the fourth air outlet 216 and then directly flows out through the first air outlet 213, since the airflow entering through the fourth air outlet 216 is not heated by the heating element 230, it will affect the heating efficiency and heating effect of the air outlet device 200.

[0316] In the case that the air outlet portion is in communication with the second air outlet 214, i.e. in the case that the second air outlet 214 is air outlet, the fourth air outlet 216 is in communication with the air inlet portion, so that the air inlet amount of the airflow can be increased, further improving the heating efficiency and heating effect of the air outlet device 200.

[0317] Optionally, in the case that the first air outlet 213 is air inlet and the second air outlet 214 is air outlet, the air inlet amount of the fourth air outlet 216 is greater than the air inlet amount of the third air outlet 215, i.e. the air inlet amount at the bottom is greater than the air inlet amount at the back, that is, the ventilation area of the third air outlet 215 is set to be smaller, so that the problem that the third air outlet 215 is air inlet due to the ventilation area of the third air outlet 215 being set to be larger when the trigger assembly 130 is located at the first position, the first edge 217 is higher than the edge of the air inlet portion of the air guide portion 140, and then the third air outlet 215 is air inlet can be avoided, further ensuring the heating effect of the air outlet device 200.

[0318] Optionally, when the first air outlet 213 takes in air and the second air outlet 214 discharges air, since the first air outlet 213 is opposite to the outer wall of part of the air guide portion 140, the air intake at the first air outlet 213 is smaller than the air intake at the third air outlet 215.

[0319] like Figure 13 As shown, in some embodiments, optionally, the air outlet device 200 further includes a switch structure 240, which is electrically connected to the heating element 230; wherein, based on the trigger component 130 being in the first position, the switch structure 240 is turned on or off, and the heating element 230 generates heat; and / or based on the trigger component 130 being in the second position, the switch structure 240 is turned on or off, and the heating element 230 generates heat.

[0320] In this embodiment, it is defined that the air outlet device 200 further includes a switch structure 240. Specifically, the switch structure 240 is electrically connected to the heating element 230. When the trigger assembly 130 is in the first position, that is, when the trigger assembly 130 drives the air guide 140 to move, so that the air guide 140 moves to the first target position, the air outlet 144 is connected to the first air outlet 213, the switch structure 240 is turned on or off, and the heating element 230 generates heat. And / or when the trigger assembly 130 is in the second position, that is, when the trigger assembly 130 drives the air guide 140 to move, so that the air guide 140 moves to the second target position, the air outlet 144 is connected to the second air outlet 214, the switch structure 240 is turned on or off, and the heating element 230 generates heat.

[0321] That is, when the trigger assembly 130 drives the air guide 140 to move to change the position of the air outlet 144, if the air outlet 144 is not connected to or opposite to the first air outlet 213 or the second air outlet 214, the state of the switch structure 240 is controlled to prevent the heating element 230 from operating. Only when the trigger assembly 130 drives the air guide 140 to move to the correct position will the heating element 230 start operating. This prevents airflow disturbances, ensures air outlet efficiency, and further improves the heat dissipation effect of the air outlet device 200.

[0322] like Figure 10 As shown, in some embodiments, optionally, the air outlet device 200 further includes a rotating shaft 250 and a wear-resistant sleeve 260, wherein the rotating shaft 250 is arranged on the side of the air guide portion 140 away from the trigger assembly 130, and the wear-resistant sleeve 260 is arranged on the shell 210, and the end of the rotating shaft 250 away from the air guide portion 140 is rotatably arranged in the wear-resistant sleeve 260.

[0323] In this embodiment, it is defined that the air outlet device 200 also includes a rotating shaft 250 and a wear-resistant sleeve 260. Specifically, the rotating shaft 250 is arranged on the side of the air guide portion 140 away from the trigger assembly 130, the wear-resistant sleeve 260 is arranged on the shell 210, and the end of the rotating shaft 250 away from the air guide portion 140 is arranged in the wear-resistant sleeve 260, and the rotating shaft 250 can rotate relative to the wear-resistant sleeve 260.

[0324] That is, when the trigger assembly 130 is triggered, the trigger assembly 130 drives the air guide part 140 to rotate relative to the shell 210, and the rotating shaft 250 rotates in the wear-resistant sleeve 260 to adjust the position of the air outlet of the air guide part 140, thereby controlling the air outlet direction.

[0325] By providing the wear-resistant sleeve 260 , the wear that occurs when the rotating shaft 250 rotates can be reduced, thereby extending the service life of the air outlet device 200 .

[0326] Optionally, the air guide portion 140 further includes a second end plate, and the second end plate is connected to the rotating shaft 250 .

[0327] Optionally, the housing 210 further includes a bracket, which is disposed in the working chamber 212 , and the wear-resistant sleeve 260 is fixedly mounted on the bracket.

[0328] In a specific embodiment, the baseboard heater (air outlet device 200) optionally has two air outlets (a first air outlet 213 and a second air outlet 214), a top air outlet (the second air outlet 214) and a front air outlet (the first air outlet 213). When the air is blown out from the top, the front air outlet becomes an air inlet, and when the air is blown out from the front, the top air outlet also becomes an air inlet. The fan (airflow generating element 220) is a cross-flow fan and is located below the heating element (heating element 230).

[0329] like Figure 11 As shown, it is the front air outlet state (air outlet from the first air outlet 213), the volute opening (air outlet portion 144) faces the front, the air flow enters from the top, passes through the heating element, and then passes through the cross-flow wind wheel (wind wheel 222), and is blown out from the front air outlet (first air outlet 213).

[0330] like Figure 12As shown, in the top air outlet state (second air outlet 214), the volute (air outlet part 144) is directed upward, the air flow enters from the bottom (fourth air outlet 216) and the front (first air outlet 213), passes through the fan wheel 222, then passes through the heating body, and is blown out from the top air outlet (second air outlet 214). At this time, the external air flow entering the toe kick heater includes three parts, one is from the front air outlet (first air outlet 213), the second is from the bottom air inlet (fourth air outlet 216), and the third is from the back air inlet (third air outlet 215). The amount of air flow is bottom > back > front. Because the back is provided with an air inlet, in the front air outlet state, in order to let the air flow enter from the top, pass through the heating body, the fan wheel, the front air outlet in turn, and avoid the air flow from the back air outlet, the edge of the front air inlet volute needs to be set higher than the edge of the back air inlet (first edge 217). The gap d between the two needs to be as small as possible, which can be determined according to the machining precision and deformation degree of the parts, generally 2-5 mm.

[0331] Specifically, the direction of the air flow is changed by rotating the volute (air guide part 140). The left volute end plate (second end plate) is provided with a rotating shaft 250 which can freely rotate in a rotating shaft sleeve (wear-resistant sleeve 260), and the rotating shaft sleeve is fixed on the support frame (support); the right volute end plate (first end plate) is installed on the motor mounting frame by a gland, and the motor mounting frame is fixed on the support plate (support frame 118), and the right volute end plate and the motor mounting frame can freely rotate. The right side of the motor mounting frame is fixed with a spring seat (mounting seat 119), and the right side of the spring seat is a spring cover (second trigger 134), which can rotate a certain angle (90° in this example) with the spring seat, and a torsional spring (first elastic member 121) is installed between the two. The spring cover is connected with the rotating shaft (mounting shaft 115), and the right side of the knob (first trigger 133) is a knob decoration cover. When the knob is rotated, the spring cover, the right volute end plate, and the volute (air guide part 140) are rotated in turn. The knob cover plays a decorative role.

[0332] The motor mounting frame, the motor, and the spring seat are all fixedly installed on the right support frame, and the support frame 118 has an avoidance slot (avoidance opening 160), and the connecting column (first connecting column 141) on the right volute end plate can pass through the avoidance slot and rotate in the avoidance slot. The connecting sleeve (second connecting column 135) on the spring cover is rigidly connected with the connecting column on the right volute end plate, and the knob is also rigidly connected with the spring cover. The spring seat is provided with a positioning head (positioning part 152), and the bottom of the positioning head is lifted by a cylindrical spring (second elastic member 151).

[0333] The spring seat has two positioning head installation holes 117, which are centrally symmetrically distributed. The positioning head and the positioning head cylindrical spring are installed in the two holes, and the head of the positioning head is exposed from the hole. The center of the spring seat protrudes a cylinder, which serves as an optional shaft (installation shaft 115) of the spring cover. There is a groove (second installation groove 116) around the cylinder for installing the torsion spring. The short arm (second arm 123) of the torsion spring is placed in the short arm groove (first installation groove 114) of the spring seat, and is fixed and immovable. The long arm (first arm 122) of the torsion spring is placed in the long arm limiting groove (limiting groove 111). After the torsion spring is installed, the long arm of the torsion spring is tightly attached to the left wall (first limiting wall 112) of the long arm limiting groove. In this state, the torsion spring has a pre-tightening force, and the positioning head is not stressed at this time. When the torsion knob is turned to drive the spring cover to rotate, the long arm of the torsion spring approaches the right limiting wall (second limiting wall 113), and the positioning head is just located in the spring cover groove 132, thereby fixing the relative position of the spring seat and the spring cover.

[0334] The long arm of the torsion spring is clamped in the long arm clamping groove 131 of the spring cover, the positioning head does not contact the inner wall of the spring cover, and the torsion spring fixes the position of the spring cover through the long arm by the pre-tightening force.

[0335] The knob drives the spring cover to rotate by a certain angle, and the volute (air guide part 140) is turned to another air outlet state. The torsion spring rotates in a tighter direction, and the positioning head changes from a state of not contacting the inner wall of the spring cover to being located in the positioning groove (groove 132) in the spring cover, thereby fixing the relative position between the spring seat and the spring cover. The torsion spring is located at positions of Figure 2 and Figure 3 , corresponding to the front air outlet and the top air outlet states.

[0336] The toe-kick line heater includes a shell (housing 210), a heating body (heating element 230), an air wheel air duct, a knob, etc. It has two states of front air outlet and top air outlet, and the air outlet direction is controlled by controlling the rotation direction of the air duct volute (air guide part 140). The rotation positioning of the volute is completed by a set of combined mechanisms, including a spring seat, a spring cover, a torsion spring, a positioning head, a positioning head spring, and a positioning groove. One arm of the torsion spring tightly abuts against a retaining wall (first limiting wall 112) to determine one position of the spring cover and the spring seat; and the positioning groove of the positioning head is directly opposite to determine another position of the spring seat and the spring cover.

[0337] The positioning head is stressed only in the vicinity of the direct opposite position of the positioning groove, and in other states, the positioning head is suspended and not stressed. The number of the positioning head and the positioning spring is greater than or equal to 2, so as to maintain the balance of the force.

[0339] In step 102, the trigger assembly is controlled to be triggered, and in the case that the trigger assembly is triggered, the trigger assembly can drive at least part of the limiting piece to move in the limiting groove and drive the air guide part to move relative to the shell to change the flow direction of the gas at the air outlet.

[0340] The control method of the air guide structure provided by the application, in particular, the air guide structure comprises a limiting piece, a limiting groove, a trigger assembly and an air guide part, the trigger assembly is connected with the limiting piece and the air guide part, that is, when the trigger assembly is triggered, at least part of the limiting piece will move in the limiting groove in the process of driving at least part of the air guide part to move relative to the shell.

[0341] Since the trigger assembly drives the air guide part to move relative to the shell, the flow direction of the gas at the air outlet can be changed, so that the user can adjust the air supply angle or air supply direction according to actual needs, which is beneficial to improve the flexibility and comfort of the user in using the air outlet device, and thus improve the user experience.

[0342] Moreover, since at least part of the limiting piece moves in the limiting groove, the movement range of the trigger assembly can be limited, thereby limiting the movement range of the air guide part, and thus the air outlet device can supply air at a set air supply angle, simplifying the control process, realizing accurate adjustment of the air supply angle or air supply direction, and ensuring the air outlet effect.

[0343] Optionally, the air guide part comprises an air guide plate arranged at the air outlet, and in the case that the trigger assembly is triggered, the air supply angle at the air outlet can be adjusted by moving the air guide plate relative to the shell.

[0344] Optionally, the air guide part comprises a volute, the volute has an air outlet part, the air outlet comprises a first air outlet and a second air outlet, and by moving the volute relative to the shell, the air outlet part can be communicated with the first air outlet or the second air outlet, that is, a suitable air outlet can be selected to supply air according to actual needs, so as to adjust the air supply direction.

[0348] When the trigger assembly reversely rotates to the second position, the trigger assembly drives the air guide part to rotate to the second target position, and the air outlet part is in communication with the second air outlet, that is, the second air outlet blows air.

[0349] That is, by controlling the forward or reverse movement of the trigger assembly, the position of the air outlet part of the air guide part can be changed, and then the first air outlet or the second air outlet can be controlled to blow air, that is, the air outlet direction can be controlled, so that the user can select the appropriate air outlet according to the actual needs, improve the flexibility and comfort of the user in using the air outlet device, and then improve the user experience.

[0351] In this embodiment, when the trigger assembly is located at the first position, the first elastic member has a deformation, so that the first arm abuts against the first limiting wall, thereby keeping the trigger assembly at the first position, and further keeping the air guide part at the first target position, thereby realizing the fixation of one kind of air supply angle or air supply direction, and ensuring the stable air blowing in this air supply angle or air supply direction.

[0352] When it is necessary to adjust the air supply angle or air supply direction, the trigger assembly is triggered and moves from the first position to the second position, the deformation amount of the first elastic member increases, and the positioning part is inserted into the groove of the trigger assembly to limit the movement of the trigger assembly, so that the trigger assembly is kept at the second position, and further keeps the air guide part at the second target position, thereby realizing the fixation of another kind of air supply angle or air supply direction, and ensuring the stable air blowing in this air supply angle or air supply direction.
