Description

[0001] The present application relates to the technical field of heating equipment, in particular to a multi-directional fan heater. BACKGROUND

[0002] In daily life, fan heaters as a common heating equipment are widely used in homes, offices and other places, but there are still many functional limitations and insufficient scene adaptability in the actual use process, which is difficult to meet the diversified and refined needs of users.

[0003] Traditional fan heaters mostly only have a single heating function, and the output direction of the warm air is fixed or the adjustment range is narrow, which leads to limited coverage of the warm air, and the blowing area cannot be flexibly adjusted according to different use scenarios. For example, when the user is in a sitting state, such as working at a desk or resting on a sofa, the warm air needs to be concentrated and cover the main activity area of the human body at a long distance, but the traditional fan heater often cannot achieve long-distance delivery of warm air due to insufficient coverage. When the user is in a lying state, such as sleeping, the head, upper body and lower body of the human body have different temperature requirements, usually 20-22℃ for the head, 22-24℃ for the upper body, and 23-25℃ for the lower body, but the traditional fan heater cannot output different temperature warm air for different parts of the human body, and cannot form a coverage area that conforms to the lying posture of the human body, which easily causes local overcooling or overheating, affecting the comfort of use. In addition, when multiple people are in the same space, the traditional fan heater cannot cover people at different positions at the same time, and it is difficult to meet the needs of multiple people taking a shower at the same time.

[0004] At the same time, the traditional fan heater lacks a comprehensive drying function for objects, and in humid weather, such as winter and plum rain season, users face the problem of difficult drying of wet clothes and shoes, and need to use additional drying equipment such as clothes hangers and dryers, which not only occupies space, but also increases the cost and inconvenience of use. Even if some fan heaters try to have a simple drying function, because the output direction of the warm air is fixed and unidirectional, and the coverage area is limited, they cannot form a comprehensive and uniform hot air coverage for the objects to be dried, resulting in low drying efficiency and failing to meet the user's demand for rapid drying of objects.

[0029] In this embodiment, it is given by Figures 1-7 a multi-directional warm air blower, which includes a frame 1, a bracket 2, an adjustment groove 31, a fixing mechanism 4, and a hot air blowing mechanism 5.

[0030] Referring to Figure 1 as shown, the frame 1 is formed by sequentially connecting the left side portion 101, the upper side portion 102, the right side portion 103, and the lower side portion 104 end to end, so that the frame 1 is in a "square" shape, and a hollow area 105 is formed at the middle position of the frame 1 for placing items to be dried; The bracket 2 is arranged between the upper side portion 102 and the lower side portion 104 to connect the upper side portion 102 and the lower side portion 104 together, and has the effect of connecting and supporting the upper side portion 102 and other components.

[0031] The number of the adjustment grooves 31 is two, and the two adjustment grooves 31 are respectively arranged at both ends of the upper side portion 102. These two ends refer to two opposite surfaces, and the adjustment groove 31 is also communicated with the side of the upper side portion 102 facing the lower side portion 104 (the side facing the ground). And at the ends of the left side portion 101 and the right side portion 103 far from the lower side portion 104, connecting members 32 rotatably connected to the adjustment groove 31 on the same side are arranged, so that the connecting members 32 can rotate around an axis perpendicular to the length direction of the upper side portion 102, and further enable the connecting members 32, the left side portion 101, and the right side portion 103 to have a horizontal state and a vertical state. Among them, the horizontal state is as Figure 3As shown, the vertical state is as Figure 2 As shown, the horizontal state and the vertical state are formed relative to the position of the multi-directional air heater of the present application, for example, relative to the ground, in the horizontal state, the left side 101, the upper side 102 and the right side 103 are in the "one" structure, in the vertical state, the left side 101, the upper side 102 and the right side 103 are in the "concave" structure, plus the lower side 104, in turn, the head and tail are connected, so that the frame 1 is in the "mouth" shape.

[0032] The fixing mechanism 4 is arranged in the inside of the adjusting groove 31, and is used for detachable fixing of the connecting piece 32 in the horizontal state, for example, in the form of clamping, buckling and extruding.

[0033] The number of the hot air blowing mechanism 5 is three, and is arranged in the left side 101, the upper side 102 and the right side 103 of the frame 1 in one-to-one correspondence. The three hot air blowing mechanisms 5 can respectively and independently blow air to three different positions, and each hot air blowing mechanism 5 can realize reciprocating rotation to respectively correspond to the temperature requirement of the head, the upper body and the lower body of the human body.

[0034] Among them, when the human body sleeps, the temperatures required by the head, the upper body and the lower body are different. Usually, the most comfortable temperatures of the three parts when the human body sleeps are: 20-22℃ for the head, 22-24℃ for the upper body and 23-25℃ for the lower body. Therefore, the three hot air blowing mechanisms 5 are combined together to form a "concave" shape, and can generate three different temperature warm air to blow the most comfortable temperature warm air to the head, the upper body and the lower body of the human body. At this time, the form of the multi-directional air heater is the contraction state different wind direction, as shown in Figure 1 .

[0035] It is mentioned above that the three hot air blowing mechanisms 5 are combined together to form a "concave" shape. When the three hot air blowing mechanisms 5 blow warm air in the same direction, a "concave" structure covering area is formed. When the three hot air blowing mechanisms 5 blow warm air in different directions, three covering areas are respectively formed. At this time, the form of the multi-directional air heater is the contraction state same wind direction, as shown in Figure 2 . Among them, the "concave" structure covering area can blow out a large range of warm air and blow warm air to a farther position, which is suitable for the case of blowing warm air to one direction, and has better practicability, for example, directly blowing warm air to a person sitting on a chair or blowing warm air to a certain middle position. Among them, the three covering areas are formed, which is suitable for the case of lying or more people. The three covering areas can cover three parts of the human body or blow up people in different positions. At this time, the form of the multi-directional air heater is the contraction state different wind direction mentioned above.

[0036] Referring to Figure 3As shown, although the three hot air blowing mechanisms 5 form three coverage areas respectively, and warm air at the most comfortable temperature can be blown to the head, upper body and lower body of the human body, the height of the hot air blowing mechanisms 5 on the left side 101 and the right side 103 is relatively low, and it is difficult to cover the human body when the bed is relatively high, and the wind blown by the hot air blowing mechanisms 5 on the left side 101 and the right side 103 has a vertical coverage range, which does not conform to the lying posture of the human body, for example Figure 1 As shown, for this purpose, during use, the left side 101 and the right side 103 can also be rotated, so that the connecting pieces 32 on the left side 101 and the right side 103 rotate around the adjusting grooves 31, and the left side 101 and the right side 103 are in the same axis direction as the upper side 102 in the length direction, that is, the horizontal state mentioned above, and then the connecting pieces 32 on the left side 101 and the right side 103 are detachably fixed by the fixing mechanism 4, so that the left side 101, the right side 103 and the upper side 102 form a coaxial state, at this time, the left side 101 and the right side 103 change from the vertical state to the horizontal state, so that the hot air blowing mechanisms 5 on the left side 101, the right side 103 and the upper side 102 are at the same height and blow warm air to the same side, and the whole forms a "one" shaped coverage area, which conforms to the lying state of the human body, for example, the human body lies on the bed to sleep, and the warm air blown by the three hot air blowing mechanisms 5 can directly blow to the head, upper body and lower body of the human body, so that the warm air in three directions can uniformly and curvedly cover the human body, at this time, the shape of the multi-directional warm air blower is an expanded state with the same wind direction, as shown in Figure 3

[0037] In order to further improve the coverage area of the hot air blowing mechanism 5, the hot air blowing mechanism 5 itself can also reciprocate and rotate, thereby improving the coverage area.

[0038] In addition, the traditional warm air blower only has a single heating function and does not have the effect of fully blowing dry objects, such as drying clothes or shoes, and the coverage range of the warm air blowing is limited, for this purpose, the frame 1 formed by the left side 101, the upper side 102, the right side 103 and the lower side 104 is connected in sequence and forms a "mouth" shaped whole, so as to form a hollow area 105 in the middle position, and the drying object can be placed in the hollow area 105, at this time, the hot air blowing mechanisms 5 on the left side 101, the upper side 102 and the right side 103 blow hot air to the hollow area 105 to dry the drying object, which is suitable for the case of quickly drying clothes, at this time, the shape of the multi-directional warm air blower is a contraction state towards the middle wind direction, as shown in Figure 4 ​As shown. In addition, the left side 101, right side 103 and upper side 102 of the coaxial state, the three hot air blowing mechanism 5 can also form a "one" shape of the warm air coverage area, to the object on the shelf drying process, for example, the clothes on the shelf hot air drying process, at this time, the multi-directional air heater form is the same direction as the expansion state, as Figure 3 And Figure 5 As shown. Among them, the clothes drying mentioned above, here the clothes refers to the winter clothes wet and not dripping, other objects to be dried as well, can not have the case of water dripping.

[0039] In summary, the multi-directional air heater can form a "concave" shape or three independent coverage areas by three hot air blowing mechanism 5, the "concave" shape of the coverage area can blow a wide range of long-distance warm air, suitable for blowing to a direction (such as blowing to the sitting person or the middle position), three independent coverage areas can be respectively to the head (20-22 ℃), the upper body (22-24 ℃), the lower body (23-25 ℃) of the human body blowing corresponding comfortable temperature of warm air, suitable for lying or multi-person scene; In addition, it can also rotate the left side 101 and the right side 103 and fixed by the fixed mechanism 4, so that the left side 101 and the right side 103 and the upper side 102 are coaxial horizontal state, so that the three hot air blowing mechanism 5 are at the same height and form a "one" shape of the coverage area, in line with the human body lying down form (such as sleep), to ensure that the warm air evenly covers the curved surface; The hot air blowing mechanism 5 itself can reciprocating rotation to further expand the coverage range; Secondly, the hollow area 105 formed by the frame 1 can place the drying objects, the three hot air blowing mechanism 5 blowing to the hollow area 105 can realize the drying of the objects, the three hot air blowing mechanism 5 in the coaxial state can also be used for hot air drying process to the objects on the shelf (such as clothes), solve the problem of the traditional air heater single function, limited coverage, no overall drying effect.

[0040] Referring to Figure 6As shown, in order to achieve the effect of detachable fixing of the horizontal connector 32 as described above, and also to consider that the connector 32 can rotate around an axis perpendicular to the length direction of the upper part 102, a groove-type extrusion structure is selected, namely the fixing mechanism 4 mentioned above. Specifically, the fixing mechanism 4 includes a connecting groove 41, a groove 42, a slider 43, and an extrusion part 44. The end of the connector 32 away from the lower part 104 extends into the interior of the adjustment groove 31 on the same side. The connecting groove 41 is located in the adjustment groove 31. 1. The inner wall opposite to the other adjustment groove 31, the connecting groove 41 matches the connecting member 32, there are two sliding grooves 42 and they are respectively set on the opposite inner wall of the adjustment groove 31, and the sliding grooves 42 extend along the length direction of the upper side 102 into the interior of the connecting groove 41, there are two sliders 43 and they are respectively installed on opposite sides of the connecting member 32, the end of the slider 43 away from the connecting member 32 extends into the interior of the sliding groove 42 on the same side, and the pressing part 44 is installed on the inner circumferential side of the connecting groove 41, and the pressing part 44 is made of elastic material.

[0041] For ease of understanding, assuming the multi-directional heater is placed on the ground, directly facing the "U"-shaped frame 1, there are two adjustment slots 31, each located at one end of the upper part 102. In this case, both adjustment slots 31 have open ends facing away from each other. However, the adjustment slots 31 on the upper part 102 are also connected to the side of the upper part 102 facing the lower part 104, meaning the end of the adjustment slot 31 facing the ground is also open. Therefore, the two opposing inner walls of the adjustment slots 31 are only front and rear inner walls, and both of these inner walls are at the same horizontal plane as the inner wall of the connecting groove 41. For example, at least one of the width or length of the adjustment slot 31 and the connecting groove 41 is the same. Figure 6 The state shown allows the slide 42 to extend along the length of the upper side 102 into the interior of the connecting groove 41.

[0042] Based on the foregoing, both the front and rear inner walls are at the same horizontal plane as the inner side wall of the connecting groove 41. Therefore, the sliding groove 42 is provided with the corresponding inner wall of the adjusting groove 31, and the sliding groove 42 extends along the length of the upper part 102 into the interior of the connecting groove 41. At the same time, the slider 43 on the connector 32 is adapted to the sliding groove 42 on the inner wall of the connecting groove 41. Therefore, the connector 32 can not only achieve the effect of rotating the slider 43 through the cooperation of the slider 43 and the connecting groove 41, but also, when the connector 32 is in a horizontal state, it can be pushed horizontally to make the slider 43 slide along the connecting groove 41, allowing the slider 43 and the connector 32 to enter the connecting groove 41. At this time, the pressing part 44 on the inner periphery of the connecting groove 41 is made of elastic material and will be squeezed and deformed by the connector 32. At the same time, it will also squeeze the connector 32, so that the connector 32 cannot be separated from the connecting groove 41 under the action of external force, so that the connector 32 and the left side part 101 and right side part 103 connected to the connector 32 remain in a horizontal state.

[0043] In order to improve the snap-fit ​​effect and prevent the connector 32 from rotating, the cross-section of the connector 32 and the interior of the connecting groove 41 are preferably rectangular, so that the connector 32 will not rotate after being inserted into the connecting groove 41. In addition, there are multiple pressing parts 44 installed on the four inner circumferential surfaces of the connecting groove 41, and the four peripheral surfaces of the connector 32 are also provided with snap-fit ​​grooves corresponding to the pressing parts 44, thereby improving the connection effect between the connector 32 and the connecting groove 41.

[0044] In summary, the fixing mechanism 4 adopts a sliding groove extrusion structure. The connecting member 32, through the cooperation of the slider 43 with the adjusting groove 31 and the sliding groove 42 on the connecting groove 41, can both rotate around the slider 43 as an axis and, when the connecting member 32 is in a horizontal state, horizontal pushing allows the slider 43 to slide along the sliding groove 42 into the connecting groove 41. Multiple elastic material extrusion portions 44 on the inner circumference of the connecting groove 41 are deformed by the connecting member 32. Simultaneously, the reverse extrusion of the connecting member 32, combined with the rectangular structure of the connecting member 32 and the connecting groove 41, and the corresponding slots on the peripheral side of the connecting member 32 and the extrusion portions 44, effectively prevents the connecting member 32 from detaching from the connecting groove 41 and from rotating, thus stably maintaining the horizontal state of the left side 101 and the right side 103. Therefore, it achieves both the rotation function of the connecting member 32 and reliable fixing in a horizontal state, improving the connection effect.

[0045] In addition, refer to Figure 6 As shown, in order to prevent the slider 43 from slipping inside the groove 42 when the connector 32, left side 101 and right side 103 change from a horizontal state to a vertical state, an arc-shaped groove 421 communicating with the inner wall of the adjustment groove 31 is provided on the side of the groove 42 opposite to the lower side 104. The slider 43 has a rod-shaped structure and matches the arc-shaped groove 421.

[0046] Specifically, when the connector 32 drives the slider 43 to rotate, the slider 43 will slide along the arc groove 421. The arc groove 421 provides a limiting effect for the rod-shaped slider 43, preventing the slider 43 from slipping in the groove 42 or from sliding during rotation, thus ensuring that the connector 32, the left side 101 and the right side 103 rotate stably when switching between horizontal and vertical states.

[0047] Based on the above, referring to Figure 3As shown, the connecting piece 32, the left side 101 and the right side 103 change from a horizontal state to a vertical state, in order to prevent the left side 101 and the right side 103 from swinging in the vertical state, a positioning groove 61 is formed on both sides of the lower side 104 in the length direction, and the left side 101 and the right side 103 are provided with a moving magnetic block 62 away from the upper side 102, and the opposite inner walls of the two positioning grooves 61 are provided with a fixed magnetic block 63, and the moving magnetic block 62 on the left side 101 and the right side 103 can be rotated to the inside of the same side positioning groove 61 through the cooperation of the arc-shaped groove 421 and the sliding block 43, so that the moving magnetic block 62 and the fixed magnetic block 63 are magnetically attracted and attached to each other.

[0048] Among them, positioning grooves 61 are formed on both sides of the lower side 104 in the length direction, and each positioning groove 61 is in communication with the side of the lower side 104 facing the upper side 102 of the frame 1, which can allow the moving magnetic block 62 on the left side 101 and the right side 103 to smoothly enter the groove during rotation.

[0049] Specifically, when the left side 101 and the right side 103 are rotated from a horizontal state to a vertical state around the connecting piece 32, the moving magnetic block 62 will rotate synchronously with the left side 101 and the right side 103, and finally accurately move to the inside of the positioning groove 61 on the corresponding side of the lower side 104, realizing preliminary position limiting. At this time, the moving magnetic block 62 and the fixed magnetic block 63 in the same positioning groove 61 and close to each other will immediately generate a magnetic attraction force, and then be closely magnetically attached. The double effect of "positioning groove 61 preliminary limiting + magnetic block magnetic attraction fixing" can form a stable constraint on the left side 101 and the right side 103 in the vertical state, effectively offsetting the shaking or swinging trend that may occur during use, and ensuring the stability of the overall structure.

[0050] In addition, referring to Figure 3 In order to expand the coverage range of the hot air blowing mechanism 5, a receiving groove 71 is formed on the same side of the left side 101, the upper side 102 and the right side 103 of the frame 1, and a plurality of hot air blowing mechanisms 5 are arranged one by one corresponding to a plurality of receiving grooves 71, and an angle adjusting driving piece 72 is arranged between the inner side wall of the receiving groove 71 and the hot air blowing mechanism 5, which is used to drive the hot air blowing mechanism 5 to rotate an angle around the receiving groove 71, and the adjustment range is 0°-180°.

[0051] Among them, the angle adjusting driving piece 72 can be selected as a motor, and the motor is embedded in the left side 101, the upper side 102 and the right side 103 to save space and facilitate the installation of the hot air blowing mechanism 5.

[0052] The accommodating groove 71 is communicated with the left side 101, the upper side 102 and the right side 103 in the width direction, so as to avoid hindering the rotation of the hot air blowing mechanism 5.

[0053] Specifically, the angle adjusting driving member 72 can drive the hot air blowing mechanism 5 to rotate around the accommodating groove 71 in the range of 0°-180°, and the axis around which the hot air blowing mechanism 5 rotates is parallel or coincides with the axis in the length direction of the left side 101 or the right side 103, so as to flexibly adjust the blowing direction to expand the coverage range of the hot air blowing mechanism 5.

[0054] And, referring to Figure 1 , in order to rotate the left side 101 and the right side 103 as a whole to improve the coverage range of the hot air blowing mechanism 5 on the left side 101 and the right side 103, the connection between the left side 101 and the right side 103 and the corresponding connecting member 32 is a damping rotation connection.

[0055] Specifically, the left side 101 and the right side 103 can rotate relative to the connecting member 32, and can be kept at any angle position by damping force when rotating, so as to adjust the orientation of the left side 101 and the right side 103 as a whole and improve the coverage range of the hot air blowing mechanism 5 thereon.

[0056] Among them, referring to Figure 3 and Figure 7 , the hot air blowing mechanism 5 comprises a shell 51, a blowing member 52 and a heating body 53, the shell 51 is arranged in the accommodating groove 71, both ends of the shell 51 are open and are respectively an air inlet and an air outlet, the blowing member 52 and the heating body 53 are arranged in the shell 51 in a spaced manner, the air outlet of the blowing member 52 faces the heating body 53, and the outer side of the shell 51 is connected with the angle adjusting driving member 72.

[0057] Optionally, the blowing member 52 is a fan, and the blowing direction of the fan faces the heating body 53 and the air outlet of the shell 51.

[0058] Specifically, the two ends of the shell 51 are open and are respectively an air inlet and an air outlet, wherein the air inlet faces the accommodating groove 71, and the air outlet faces away from the accommodating groove 71.

[0059] More specifically, the blowing member 52 and the heating body 53 arranged in the shell 51 in a spaced manner are respectively located at the air inlet and the air outlet, and the air outlet of the blowing member 52 faces the heating body 53, and in operation, the blowing member 52 inhales air from the air inlet and blows the air to the heating body 53, the air is heated by the heating body 53 to form warm air, and then the warm air is blown out from the air outlet, and the outer side of the shell 51 is connected with the angle adjusting driving member 72, so that the shell 51 and the blowing member 52 and the heating body 53 inside the shell 51 can be rotated together by the driving member, and the adjustment of the blowing direction of the warm air is realized.

[0060] In addition, in order to make the shell 51 rotate more smoothly, a rotating shaft is also installed on the side opposite to the side connected with the angle adjusting driving element 72 of the shell 51, and the other end of the rotating shaft is also connected with the inner side wall of the accommodating groove 71 in a rotating manner, thereby providing double-side support for the shell 51, avoiding the shell 51 from shaking and deviating due to unbalanced force when being connected with the angle adjusting driving element 72 on one side, and enabling the shell 51 to rotate stably around the double-side fulcrum under the driving of the angle adjusting driving element 72.

[0061] In addition, as shown in Figure 7 , the inner side wall of the accommodating groove 71 is provided with a plurality of ventilation holes 711, so as to accelerate the circulation of air and enable the air to be quickly sucked into the shell 51 by the air blowing element 52.

[0062] In addition, as shown in Figure 7 , the two openings of the shell 51 are respectively provided with a filter screen 81 and a grille 82.

[0063] Specifically, the filter screen 81 is arranged at the air inlet of the shell 51, which is used to filter the impurities and dust in the sucked air, so as to avoid the impurities and dust from entering the shell 51 to pollute the air blowing element 52 and the heating body 53 or affect the operation of the components; the grille 82 is arranged at the air outlet of the shell 51, which can not only comb the heated warm air to make the air outlet more uniform, but also can play a protection role to prevent external foreign matters from entering the shell 51 or avoid the internal components from being touched by mistake.

[0064] Specifically, the filter screen 81 is arranged at the air inlet of the shell 51, which is used to filter the impurities and dust in the sucked air, so as to avoid the impurities and dust from entering the shell 51 to pollute the air blowing element 52 and the heating body 53 or affect the operation of the components; the grille 82 is arranged at the air outlet of the shell 51, which can not only comb the heated warm air to make the air outlet more uniform, but also can play a protection role to prevent external foreign matters from entering the shell 51 or avoid the internal components from being touched by mistake. Figure 7

[0065] Specifically, the ion generator 54 is arranged at one side of the air outlet of the air blowing element 52, and a large number of positive and negative ions are generated when the ion generator 54 works. The air blowing element 52 sucks air from the outside of the shell 51 and blows the air into the shell 51, and at the same time, blows the ions forward, and then the ions are blown out together with the warm air blown out by the air blowing element 52 and the heating body 53, and acts on the clothes that are dry or have odor. The ions can chemically react with odor molecules (such as organic acids, amines and the like generated by sweat decomposition) on the clothes, destroy the chemical structure of the odor molecules, decompose the odor molecules into odorless small molecular substances (such as carbon dioxide, water and the like), thereby realizing the deodorization effect on the clothes.

[0066] Specifically, the left side 101, the upper side 102, the right side 103 and the lower side 104 of the frame 1 are all cavity structures, which provide space for accommodating electronic components and lines.

[0067] In addition, as shown in Figure 7 , in order to detect and control the temperature of the warm air blown out by the hot air blowing mechanism 5, a controller is arranged in the frame 1, and a temperature sensor 9 is arranged at the air outlet of the shell 51.​

[0068] The controller is connected with the heating body 53 and the temperature sensor 9.

[0069] Specifically, the range of the blowing warm air temperature can be set by the controller. During operation, the temperature sensor 9 can detect the temperature of the blowing warm air of the blowing warm air mechanism 5 in real time and transmit the temperature signal to the controller. After receiving the signal, the controller compares the preset temperature range. If the actual temperature is lower than the preset value, the heating power of the heating body 53 is increased. If the actual temperature is higher than the preset value, the heating power of the heating body 53 is decreased.

[0070] In addition, a display screen is installed on the frame 1. The controller is further connected with the display screen, the air blowing member 52 and the ion generator 54. A plurality of adjusting buttons are installed on the frame 1. The adjusting buttons are connected with the controller, so as to control the start and stop of the air blowing member 52, the heating body 53 and the ion generator 54 and adjust the temperature of the blowing warm air of the blowing warm air mechanism 5. The display screen is used for displaying the temperature of the blowing warm air of the three blowing warm air mechanisms 5, so that the user can intuitively know the actual temperature.

[0071] In summary, the multi-directional warm air blower has rich functions and high practicability. The frame 1 is in the shape of a mouth and forms a hollow area 105, in which the drying objects can be placed. The three blowing warm air mechanisms 5 of the left side 101, the upper side 102 and the right side 103 can blow warm air to the hollow area 105, so as to dry the objects. In the coaxial state, the objects on the shelf can also be hot-blow dried, which solves the problem that the traditional warm air blower has no overall drying effect. In addition, the three blowing warm air mechanisms 5 can form a “concave” shape or three independent coverage areas. The “concave” shape can blow warm air in a large range and at a long distance, which is suitable for blowing warm air to people who sit or to the middle open position. The three independent coverage areas can blow corresponding comfortable temperature warm air to the head (20-22℃), the upper body (22-24℃) and the lower body (23-25℃) of the human body, respectively, which is suitable for people who lie or for a multi-person scene. The left side 101 and the right side 103 can rotate around the connecting member 32, which can be in the coaxial horizontal state with the upper side 102 in cooperation with the fixing mechanism 4, so that the three blowing warm air mechanisms 5 are at the same height and form a “one” shaped coverage area, which conforms to the lying posture of the human body and ensures that the warm air uniformly covers the curved surface. The fixing mechanism 4 realizes the rotation of the connecting member 32 and the stable fixation in the horizontal state through the connecting groove 41, the sliding groove 42, the sliding block 43 and the extrusion part 44. The arc-shaped groove 421 cooperates with the rod-shaped sliding block 43 to avoid rotation slip. The magnetic attraction cooperation of the positioning groove 61 of the lower side 104, the moving magnetic block 62 and the fixed magnetic block 63 can prevent the left side 101 and the right side 103 from swinging in the vertical state. The blowing warm air mechanism 5 can rotate in the range of 0°-180° around the accommodating groove 71 through the angle adjusting driving member 72. The ions generated by the ion generator 54 in the blowing warm air mechanism 5 act on the clothes with odor along with the warm air, so as to decompose odor molecules and achieve deodorization.
