Description

Technical Field

[0001] The present invention relates to the technical field of intelligent bathroom technology, and in particular to a telescopic drying device for an intelligent toilet cover and an intelligent toilet cover having the telescopic drying device. Background Art

[0002] Traditional smart toilet lids usually have only one air outlet, for example, only one rear air outlet or only one front air outlet. If one air outlet is used to dry the middle and both sides of the buttocks at the same time, the air outlet area is large, the wind speed is low, the drying time is correspondingly increased, the drying efficiency is low, and the effect is poor.

[0003] In order to improve the drying efficiency, the conventional double-air outlet drying device mainly adopts:

[0004] 1. Install two heaters, each with an outlet. Specifically, the outlets of the left and right heaters are oriented toward the center and tilted upward. The two heaters blow air simultaneously, generating combined wind force that rotates, accelerating the removal of water droplets and improving drying efficiency. This solution requires two sets of heaters, resulting in high hardware costs, bulk, and weight. Furthermore, while this solution increases wind force after combined warm air, it lacks effective design considerations for the human buttocks, limiting the drying area.

[0005] 2. Install a heater that simultaneously discharges air through two fixed outlets. For example, two outlets are fixed on the end face of the drying tube. This solution makes it impossible to adjust the outlet position or move it to sweep air, as the two outlets are fixed. Furthermore, the outlet cannot be extended or discharged from bottom to top, limiting the drying area. Summary of the Invention

[0051] like Figure 1 As shown, the drying duct 20 can telescope between an extended position and a retracted position, and the drying duct 20 can extend and retract in an arc shape. The first air outlet 212 is oriented forward, for drying the body from the rear. The first air outlet 212 can be adjusted vertically during the extension and retraction of the drying duct 20, enabling vertical drying. The second air outlet 222 is oriented upward or tilted upward, for blowing and sweeping air from the bottom up. The second air outlet 222 can be adjusted front-to-back during the extension and retraction of the drying duct, enabling vertical drying.

[0052] The drying pipe 20 has a first air outlet 212 and a second air outlet 222 that are connected or disconnected with the main air outlet channel 11; when the drying pipe 20 is in the retracted position, the main air outlet channel 11 is connected to the first air outlet 212; when the drying pipe 20 is in the extended position, the main air outlet channel 11 is connected to the second air outlet 222. Figure 6As shown, in this embodiment, the first air outlet 212 is opened on the front end surface of the drying tube 20 , and the second air outlet 222 is opened on the top surface of the front portion of the drying tube 20 .

[0053] The first branch air duct 21 and the second branch air duct 22 are arranged in the drying pipe 20. When the drying pipe 20 is in the retracted position, the main air outlet channel 11 is connected to the first air outlet 212 through the first branch air duct 21; when the drying pipe 20 is in the extended position, the main air outlet channel 11 is connected to the second air outlet 222 through the second branch air duct 22.

[0054] The first branch air duct 21 is provided with a first air inlet 211, and the second branch air duct 22 is provided with a second air inlet 221. When the drying duct 20 is in the retracted position, the outlet of the main air outlet duct 11 is connected to the first air inlet 211. When the drying duct 20 is in the extended position, the outlet of the main air outlet duct 11 is connected to the second air inlet 221. In this embodiment, the first air inlet 211 and the second air inlet 221 are spaced apart in front and back along the extension direction of the drying duct 20.

[0055] like Figure 6 As shown, the bracket 10 or a component fixed relative to the bracket 10 is provided with a first guide structure, along which the drying tube 20 moves between an extended position and a retracted position. The first guide structure utilizes an arcuate guide rail 12. The arcuate guide rail 12 can utilize an arcuate guide groove or an arcuate rib. Furthermore, the fan unit 50 is provided with an induced draft duct 51, and the main air outlet channel 11 is connected to the induced draft duct 51. Furthermore, a heating group 70 is provided within the induced draft duct 51 or the main air outlet channel 11 to increase the air temperature.

[0056] The driving mechanism includes a driving motor 60 and a driving gear 61, and the center hole of the driving gear 61 is drivingly connected to the output shaft of the driving motor 60; the outer wall of the drying tube 20 is provided with a row of driven teeth 23 along the extension direction, and preferably, the driven teeth 23 are arranged on the top wall or bottom wall of the drying tube 20; the driving gear 61 is engaged with the driven teeth 23, and drives the drying tube 20 to extend and retract back and forth under the drive of the driving motor 60.

[0057] like Figure 2 and Figure 3 As shown, when the drying tube 20 is in the contracted state: the outlet of the main air outlet channel 11 is connected to the first air inlet 211, and then connected to the first air outlet 212 through the first branch air duct 21 to discharge air from the first air outlet 212, so that air can be discharged from the back to the front and the air outlet position can be adjusted from top to bottom to sweep the air up and down.

[0058] like Figure 4 and Figure 5 As shown, when the drying pipe 20 is in the extended position: the outlet of the main air outlet channel 11 is connected with the second air inlet 221, and then connected with the second air outlet 222 through the second branch air duct 22 to discharge air from the second air outlet 222, so that air can be discharged from the second air outlet 222, and the air can be discharged from the bottom to the top and the air outlet position can be adjusted forward and backward.

[0059] Second embodiment (the main air outlet channel is set in the drying tube and is switched to the first branch air channel or the second branch air channel by a switching member)

[0060] like Figures 7 to 14 As shown, the main difference between this embodiment and the first embodiment is that in this embodiment, the main air outlet channel 11 is provided on the drying duct 20, and a switching member 30 is movably mounted within the main air outlet channel 11. The drying duct 20 is telescopically mounted on the bracket 10, and the switching member 30 cooperates with the telescopic movement of the drying duct 20. Alternatively, the switching member 30 can be directly driven by a motor.

[0061] The first air inlet 211 and the second air inlet 221 are arranged side by side along the radial direction of the drying duct 20. The first air inlet 211 or the second air inlet 221 can be switched open by a switching member 30. The first air outlet 212 of the drying duct 20 can discharge air from the rear end and can be adjusted vertically; the second air outlet 222 of the drying duct 20 can discharge air upward and can be adjusted front-to-back.

[0062] In this embodiment, a guide structure is provided on the bracket 10 or a component fixed relatively to the bracket 10, and the switching member 30 is driven by the drying pipe 20 to move along the guide structure between a position where the first air inlet 211 is opened and a position where the second air inlet 221 is opened; Figure 7 and Figure 8 As shown, in this embodiment, the guide structure adopts a direction-changing guide rail 13 , and the switching member 30 adopts a baffle. The baffle has a guide shaft 31 , and the guide shaft 31 cooperates with the direction-changing guide rail 13 in a guiding manner.

[0063] like Figure 10 、 12As shown in Figures 14 and 14, the changing guide rail 13 includes a first guide section L1, a changing arc section L2 and a second guide section L3. When the switching member 30 cooperates with the first guide section L1, the switching member 30 is located at a position for opening the first air inlet 211, and the total air outlet channel 11 is connected to the first air outlet 212; when the switching member 30 cooperates with the second guide section L3, the switching member 30 is located at a position for opening the second air inlet 221, and the total air outlet channel 11 is connected to the second air outlet 222; under the action of the changing arc section L2, the switching member 30 moves between a position for opening the first air inlet 211 and a position for opening the second air inlet 221.

[0064] like Figure 9 and Figure 10 As shown, when the drying duct 20 is in a retracted state, that is, the baffle guide shaft 31 is in the rear end arc section (first guide section L1), and the drying duct 20 is extended and retracted in the arc direction of the rear end arc section; at this time, the baffle (switching member 30) blocks the second air outlet 222, and the first air outlet 212 is open, and the fan unit 50 can discharge air from the back to the front. At the same time, as the drying duct 20 is extended and retracted in the arc direction, the first air outlet 212 can discharge air from the rear end and adjust the air position up and down.

[0065] like Figure 11 and Figure 12 As shown, when the baffle guide shaft 31 is in the direction-changing arc section, the baffle rotates clockwise from the second air outlet 222 to the first air outlet 212 as the drying tube 20 extends.

[0066] like Figure 13 and Figure 14 As shown, when the baffle guide shaft 31 passes the redirecting arc segment L2, the drying tube 20 expands and contracts in the arc direction at the front arc segment (the second guide segment L3). At this time, the baffle rotates to block the first air outlet 212. Under the action of gravity and wind force, the baffle always keeps blocking the first air outlet 212, and the second air outlet 222 is opened to discharge air. At the same time, during the expansion and contraction process of the drying tube 20, the second air outlet 222 can realize the discharge of air from bottom to top and the adjustment of the front and back air outlet positions.

[0067] In addition, the present invention further provides an intelligent toilet seat, which includes the telescopic drying device described in any one of the first and second embodiments.

[0068] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
