DETAILED DESCRIPTION

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The utility model relates to a drying device, which comprises an air duct component 100, an air guide component 200, a reversing sleeve 300, a driving mechanism 400 and an air supply component 500.

[0038] The air duct assembly 100 is provided with at least two air outlets 101, and the number of air outlets 101 can be two, three or even more. The air guide assembly 200 is installed in at least one air outlet 101, that is, one air outlet 101 in the air duct assembly 100 is installed with the air guide assembly 200, or multiple or all air outlets 101 are installed with the air guide assembly 200. As shown in Figures 1, 2 and 3, this embodiment is described by taking the air duct assembly 100 as an example to install two air outlets 101. The two air outlets 101 are defined as the first air outlet 130 and the second air outlet 140 respectively. The first air outlet 130 and the second air outlet 140 have different orientations on the air duct assembly 100. The air guide assembly 200 is installed in the second air outlet 140. Among them, the second air outlet 140 can be set to be fan-shaped and expanded, and the air guide assembly 200 swings along the fan-shaped opening direction of the second air outlet 140, thereby effectively increasing the blowing range. The reversing sleeve 300 is installed in the air duct assembly 100, and the driving mechanism 400 is connected to the reversing sleeve 300. The driving mechanism 400 uses a motor, and the driving shaft of the motor can be directly connected to the reversing sleeve 300, or can be connected to the reversing sleeve 300 through a transmission component such as a gear set or a connecting rod set. The driving mechanism 400 drives the reversing sleeve 300 to rotate in the air duct assembly 100, and the rotation mode of the reversing sleeve 300 can be set to unidirectional rotation or bidirectional reciprocating rotation. When the reversing sleeve 300 rotates, it can be connected with each air outlet 101 in sequence, switch between the first air outlet 130 and the second air outlet 140, and connect with the first air outlet 130 or the second air outlet 140. The air supply assembly 500 uses a fan, and the fan can be used in conjunction with the heating component to selectively blow out cold air or hot air. The air supply component 500 is connected to the reversing sleeve 300, and the wind blown out by the air supply component 500 passes through the reversing sleeve 300 and blows out from the first air outlet 130 or the second air outlet 140. Among them, a linkage structure is provided between the reversing sleeve 300 and the air guide component 200. The reversing sleeve 300 drives the air guide component 200 to swing through the linkage structure, and the linkage structure will enter the working state only when the reversing sleeve 300 is switched to be connected to the air outlet 101 on which the air guide component 200 is installed. In this embodiment, the air guide component 200 is installed in the second air outlet 140. As shown in Figure 7, when the reversing sleeve 300 is switched to be connected to the first air outlet 130, the wind is blown out from the first air outlet 130 through the reversing sleeve 300, and at this time, the second air outlet 140 is in a closed state and does not emit air, and the linkage structure is in a non-working state. The driving mechanism 400 is started, as shown in Figure 8, and the reversing sleeve 300 is rotated to be connected with the second air outlet 140, and the first air outlet 130 is closed. At this time, the linkage structure enters the working state, and during the rotation of the reversing sleeve 300, the air guide assembly 200 is synchronously driven to swing in the second air outlet 140, thereby changing the direction of the wind when it is blown out from the second air outlet 101, so as to increase the coverage area of ​​the wind.When the driving mechanism 400 drives the reversing sleeve 300 to rotate only in one direction, the rotation speed of the driving mechanism 400 can be set to control the swing speed of the air guide assembly 200. Preferably, the driving mechanism 400 of this embodiment uses a motor that can rotate forward and reverse, and the driving mechanism 400 can be connected to an external control system, and the speed and forward and reverse stroke of the driving mechanism 400 are controlled by the control system. After the reversing sleeve 300 rotates to align with the second air outlet 140, within the rotation range where the reversing sleeve 300 is connected to the second air outlet 140, the driving mechanism 400 drives the reversing sleeve 300 to rotate forward and reverse, and then drives the air guide assembly 200 to swing back and forth through the linkage mechanism, so that the wind is blown out from the second air outlet 140 in a large fan shape. The linkage component cleverly links the reversing sleeve 300 and the air guide component 200, and only the same driving mechanism 400 is required to realize the position switching of the reversing sleeve 300 and different air outlets 101 to provide different blowing and drying modes, and utilize the linkage structure to drive the air guide component 200 to swing to increase the blowing area.

[0039] In actual use, the drying device can be applied to various products that need to be dried in different modes. In this embodiment, the drying device is applied to the smart cover. As shown in Figure 5, the smart cover also includes a spray gun assembly 700, which is installed on the cover seat. The smart cover is applied to the smart toilet. The spray gun assembly 700 is used to spray water to clean the user's buttocks. One of the air outlets 101 of the drying device is used to blow air to dry the buttocks after spraying water. The spray gun assembly 700 is located on one side of at least one of the air outlets 101 on which the air guide assembly 200 is installed. In the figure, the spray gun assembly 700 is installed in the air outlet direction of the second air outlet 140. The first air outlet 130 is facing the position of the buttocks. After using the cleaning function, the reversing sleeve 300 rotates to the first air outlet 130, and the air supply assembly 500 blows air to dry the buttocks through the reversing sleeve 300 and the first air outlet 130. Then the reversing sleeve 300 rotates to the second air outlet 140, and the reversing sleeve 300 and the air guide assembly 200 cooperate to blow air toward the spray gun assembly 700, drying the spray gun assembly 700 and its surrounding environment, effectively reducing bacterial growth, and at the same time making the internal environment of the smart cover dry, which is beneficial to extending the service life of internal components.

[0040] The linkage structure may be, but is not limited to, a push rod is provided on the reversing sleeve 300, and the push rod swings with the rotation of the reversing sleeve 300. When the push rod swings to align with the air guide assembly 200, the air guide assembly 200 can swing through the push rod wave. In some specific embodiments of the utility model, as shown in FIG3, the linkage structure includes a transmission member 600 and an incomplete gear 310. The transmission member 600 may be a plate member, and the transmission member 600 may be rotatably mounted on the air duct assembly 100 through a rotating shaft or the like. The axial direction of the transmission member 600 is parallel to the axial direction of the reversing sleeve 300. The incomplete gear 310 is coaxially arranged on the reversing sleeve 300. The incomplete gear 310 may be installed on the reversing sleeve 300 as an independent part, or may be integrally formed on the reversing sleeve 300. The incomplete gear 310 is that a part of the gear teeth is provided on the side wall of the wheel body, and the other part is a smooth surface. A tooth portion 610 is also provided on the transmission member 600. The tooth portion 610 on the transmission member 600 can be a complete tooth surface or an incomplete tooth surface. In the figure, three gear teeth are arranged on the incomplete gear 310, and three gear teeth are arranged on the transmission member 600 accordingly. The transmission member 600 and the air guide assembly 200 can be connected by a transmission structure such as a connecting rod group, and the air guide assembly 200 is driven to swing by the transmission member 600. When in use, when the reversing sleeve 300 is aligned with the first air outlet 130, the smooth surface on the incomplete gear 310 is opposite to the transmission member 600, and the gear teeth on the incomplete gear 310 do not mesh with the gear portion 610 of the transmission member 600, and the air guide assembly 200 does not swing at this time. When the reversing sleeve 300 rotates to align with the second air outlet 140, the incomplete gear 310 rotates until its gear teeth mesh with the gear portion 610 on the transmission member 600, and drives the transmission member 600 to rotate during the meshing process, thereby driving the air guide assembly 200 to swing relative to the second air outlet 140. The overall structure is simple, and through the cooperation between the incomplete gear 310 and the transmission member 600, the steering process of the reversing sleeve 300 and the air guide assembly 200 can be precisely linked without the need for another motor to drive.

[0041] Furthermore, an elastic member 620 is installed on the transmission member 600. The elastic member 620 can be a spring, a torsion spring, a tension spring, etc. In this embodiment, as shown in Figures 3, 7 and 8, the elastic member 620 uses a tension spring, one end of which is connected to the transmission member 600, and the other end is connected to the air duct assembly 100. The elastic member 620 has an elastic force on the transmission member 600, and the elastic force pulls the transmission member 600 to rotate in the first direction. When the incomplete gear 310 is engaged with the transmission member 600, the incomplete gear 310 drives the transmission member 600 to rotate in the second direction. The first direction and the second direction are opposite directions. In the direction shown in the figure, the direction in which the elastic force pulls the transmission member 600 to rotate is counterclockwise (first direction), and the direction in which the reversing sleeve 300 rotates from the first air outlet 130 to the second air outlet 140 is counterclockwise. When the reversing sleeve 300 rotates counterclockwise, the incomplete gear 310 meshes with the transmission member 600, driving the transmission member 600 to overcome the elastic force of the elastic member 620 and rotate clockwise (the second direction), and the first direction is opposite to the second direction. When the reversing sleeve 300 rotates clockwise, the transmission member 600 is driven to rotate counterclockwise by the incomplete gear 310. When the reversing sleeve 300 rotates clockwise from the second air outlet 140 to the first air outlet 130, the gear teeth on the incomplete gear 310 disengage from the tooth portion 610 of the transmission member 600, and the transmission member 600 is reset to the initial position under the elastic force and waits for the next meshing, thereby determining the meshing initial position and initial swinging position of the transmission member 600 each time, and avoiding the deviation or over-travel of the swinging direction of the air guide assembly 200 driven by the transmission member 600.

[0042] In some specific embodiments of the present invention, as shown in FIG. 3 , the transmission member 600 is rotatably installed in the air duct assembly 100 by means of a pin 630. A hole may be opened at the rotation center of the transmission member 600, and the pin 630 is inserted through the rotation center of the transmission member 600, and then the end of the pin 630 is buckled on the inner wall of the air duct assembly 100. The transmission member 600 is limited relative to the air duct assembly 100 in the axial direction by the pin 630, and rotates around the pin 630 at the same time. The transmission member 600 extends a guide bar portion 640, and the guide bar portion 640 extends from the side wall of the transmission member 600 perpendicular to the axial direction of the transmission member 600. As shown in FIG. 4 , a guide groove 641 is opened on the guide bar portion 640, and the guide groove 641 is linearly extended, and may be perpendicular to the axial extension of the transmission member 600. The air guide assembly 200 is rotatably mounted in the air outlet 101, and a connecting rod or a connecting shaft can be provided on the air guide assembly 200 to be slidably connected to the guide groove 641. When the transmission member 600 rotates, the guide bar portion 640 swings along with the transmission member 600, and the air guide assembly 200 is driven to swing through the guide groove 641, and the connecting rod or the connecting shaft on the air guide assembly 200 slides relative to the guide groove 641.

[0043] Further, as shown in FIG. 7 and FIG. 8 , the air duct assembly 100 is provided with a first limit block 110 and a second limit block 120, and the first limit block 110 and the second limit block 120 can be protruded from the inside of the air duct assembly 100. The first limit block 110 and the second limit block 120 are respectively located on the forward and reverse paths of the transmission member 600. When the transmission member 600 rotates counterclockwise to a certain position, it can abut against the first limit block 110, and the guide bar portion 640 on the transmission member 600 can abut against the first limit block 110, thereby limiting the travel position of the transmission member 600 rotating counterclockwise. When the transmission member 600 rotates clockwise to the first position, it can abut against the second limit block 120, and the guide bar portion 640 on the transmission member 600 can abut against the second limit block 120, thereby limiting the travel position of the transmission member 600 rotating clockwise. The first limit block 110 and the second limit block 120 are used to limit the rotation position of the transmission member 600, thereby controlling the swing amplitude of the air guide assembly 200 and determining the blowing range of the air guide assembly 200.

[0044] The air guide assembly 200 may use a fan blade component, and the fan blade component is rotatably installed in the air outlet 101 through a rotating shaft to swing. In some specific embodiments of the utility model, as shown in Figure 3, the air guide assembly 200 includes a main air guide blade 210, an auxiliary air guide blade 220 and a connecting plate 230. The main air guide blade 210 and the auxiliary air guide blade 220 are plate-shaped, and a rotating shaft can be set at both ends of the main air guide blade 210 and the auxiliary air guide blade 220, and they are rotatably installed on the side wall of the air outlet 101 through the rotating shaft. One main air guide blade 210 can be provided, and multiple auxiliary air guide blades 220 can be provided. The main air guide blade 210 and each auxiliary air guide blade 220 are arranged in the air outlet 101 in sequence and spaced apart, and are placed parallel to each other.

The main air guide blade 210 and the auxiliary air guide blade 220 are both provided with convex shafts, which extend parallel to the axial direction of the main air guide blade 210 and the auxiliary air guide blade 220. The connecting plate 230 can be provided as a long strip structure, and the convex shafts on the main air guide blade 210 and the auxiliary air guide blade 220 are connected to the connecting plate 230.
