Description

Technical Field

[0001] The present invention relates to the field of sanitary wares, in particular to an automatically telescopic drying device and a toilet bowl. Background Art

[0002] Currently, the intelligent toilet drying technology mainly includes the following several types: 1. Using a blower and a drying heating wire, the wind speed of the blower is limited and the distance from the buttocks is relatively far, so the drying effect is not good; 2. Using a blower, a drying heating wire, a moving rod and a motor, the motor drives the moving rod to move a certain distance, making the distance closer to the buttocks. However, the motor occupies part of the volume, resulting in a limited cross-sectional area of the air duct and a limited drying area. The wind speed of the blower is low and it is difficult to achieve the effect of rapid drying.

[0003] Therefore, the existing intelligent toilet drying has the following problems: 1. The wind speed and wind pressure are low, and the transmission distance of the wind is short. Even with a telescopic rod, the amount of wind reaching the buttocks is very limited; 2. The distance from the buttocks is far and the drying efficiency is low; 3. It is impossible to dry within a short time (for example, 3 minutes). Summary of the Invention

[0004] The main purpose of the present invention is to overcome the defects in the existing drying technology, such as the need for a motor to drive the telescopic rod to move, low wind speed and low air pressure, large volume and poor drying effect, and to propose an automatically telescopic drying device and a toilet bowl, which have a simple structure, low cost and high drying efficiency.

[0005] The present invention adopts the following technical solutions:

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments Specific embodiments

[0044] The present invention will be further described below through specific embodiments

[0045] Refer to Figures 1 to 18 , an automatically telescopic drying device, including a bracket 10, a fan 20, a heating unit 30, a telescopic rod group 40, etc. The fan 20 and the heating unit 30 are installed in the bracket 10. The fan 20 is located at the air inlet 11 of the bracket 10, and the heating unit 30 is located at the air outlet 51 of the fan 20; the telescopic rod group 40 is sleeved between the bracket 10 and the heating unit 30, and one end thereof is provided with an air outlet head 50; the air outlet head 50 is provided with an air outlet 51, and at least one pushing area 52 is provided on the inner wall of the air outlet head 50 near the air outlet 51 to drive the telescopic rod group 40 to move and extend under the action of wind force

[0046] In the present invention, the pushing area 52 forms an angle with the air outlet direction of the heating unit 30, and the angle is an obtuse angle or an acute angle. Refer to Figure 1 for the included angles a and b, when the hot air blown by the heating unit 30 reaches the pushing area 52, it encounters resistance, thereby generating a thrust on the air outlet head 50. In addition, the orientation of the air outlet 51 also forms an angle with the air outlet direction of the heating unit 30. Refer to Figure 1 , the orientation of the air outlet 51 can be inclined upward, and its shape can be circular, oval, rectangular or other special shapes, preferably oval

[0047] Further, the pushing area 52 is located around or at least on one side of the air outlet 51. The area of the pushing area 52 can be larger than, smaller than, or equal to the area of the air outlet 51, as long as it can generate sufficient driving force, and preferably it is larger than the area of the air outlet 51. The number, position, shape, etc. of the pushing areas 52 can be set as needed, where at least one side means that at least one pushing area 52 is arranged at intervals on the outer periphery of the air outlet 51 and is located on different sides.

[0048] Preferably, referring to Figure 4 , the pushing area 52 is arranged in a ring around the outer periphery of the air outlet 51, similar to a ring shape, and the center of the pushing area 52 does not coincide with the center of the air outlet 51. The width of the pushing area 52 in the circumferential direction can gradually increase first and then decrease or decrease first and then increase. The air passing area is large at the place with a larger width, and the air passing area is small at the place where the width decreases.

[0049] In the present invention, the pushing area 52 can be one or both of a plane or an arc surface, and the inner wall of the air outlet is an inclined surface, an arc surface, or a plane. For example, referring to Figures 11 to 13 is a cross-sectional view in the second direction. On this cross-section, the pushing area 52 is a plane, and the inner wall of the air outlet 51 is similar to an inclined surface 53, and this inclined surface 53 is inclined outward along the air outlet direction, similar to a horn shape. Referring to Figures 14 to 18 is a cross-sectional view in the third direction. The pushing area 52 is an arc surface, and the inner wall of the air outlet 51 is also an arc surface 54.

[0050] In this embodiment, by adjusting the installation direction of the drying device, when the wind force of the fan 20 disappears, the telescopic rod group 40 and the air outlet head 50 can return to their original positions under the action of gravity. For example, the telescopic rod group � can be set to be inclined or perpendicular to the horizontal plane.

[0051] Preferably, a return member 60 can be provided and installed between the bracket 10 and the telescopic rod group 40, and is used to drive the telescopic rod group 40 to return when the wind force disappears. The return member 60 can be a spring. The number and position of the return member 60 can be set as needed and are not limited. In this embodiment, the return member 60 is located on the side of the telescopic rod group 40, and the number is two. Under normal conditions, under the action of the return member 60, the telescopic rod group 40 is in a contracted state; when the telescopic rod group 40 extends under the action of wind force, the telescopic rod group 40 compresses the return member 60 to store energy.

[0052] To ensure that the telescopic movement is smoother and more reliable, at least one slider 41 is provided on the telescopic rod group 40, and at least one guide groove 12 is correspondingly provided on the bracket 10. The slider 41 and the guide groove 12 are in sliding fit, and the return member 60 is installed between the slider 41 and the inner wall of the guide groove 12. The guide groove 12 can be parallel to the telescopic direction of the telescopic rod group 40. The number of the sliders 41 and the guide grooves 12 can respectively correspond to the number of the return members 60.

[0053] The telescopic rod group 40 of the present invention includes a fixed sleeve 42, a first telescopic rod 43, a second telescopic rod 44, etc. The fixed sleeve 42 is fixed relative to the bracket 10. The first telescopic rod 43 is slidably sleeved outside the fixed sleeve 42, and the second telescopic rod 44 is slidably sleeved outside the first telescopic rod 43; the air outlet 50 is fixedly connected to the second telescopic rod 44. Among them, the heating unit 30 can be installed inside the fixed sleeve 42, and the slider 41 can be arranged on the second telescopic rod 44.

[0054] Further, a first limiting protrusion 45 is provided between the first telescopic rod 43 and the fixed sleeve 42, and a second limiting protrusion 46 is provided between the second telescopic rod 44 and the first telescopic rod 43. Through the first limiting protrusion 45 and the second limiting protrusion 46, the telescopic displacements of the first telescopic rod 43 and the second telescopic rod 44 are limited, respectively avoiding the first telescopic rod 43 and the second telescopic rod 44 from detaching from the fixed sleeve 42 and the first telescopic rod 43.

[0055] Specifically, the second limiting protrusion 46 is located at one end of the second telescopic rod 44 away from the air outlet 50. One end of the first telescopic rod 43 is provided with the second limiting protrusion 46, and the other end is provided with the first limiting protrusion 45. The fixed sleeve 42 is correspondingly provided with the first limiting protrusion 45.

[0056] For the telescopic rod group 40 of the present invention, its maximum telescopic length can be set as needed, which is achieved by adjusting the number of telescopic rods or the length of each telescopic rod, without limitation. The air outlet can be integrally formed with or separately arranged from the telescopic rod group 40.

[0057] The present invention can also be provided with a fan sleeve 21, which is installed inside the bracket 10 and used to fix the fan 20. The fan sleeve 21 and the bracket 10 can be locked by bolts. A silica gel sleeve 22 can also be provided between the fan sleeve 21 and the fan 20 to play a role in buffering and noise reduction. The fan 20 can adopt a high-speed fan to achieve high wind speed and high wind pressure, and the heating unit 30 can adopt a heating wire. The fixed sleeve 42 of the telescopic rod group 40 can be detachably connected to the fan sleeve 21 for easy assembly, such as snap fit.

[0058] The present invention also proposes an intelligent toilet, which includes a toilet body and the above-mentioned automatic telescopic drying device. The toilet body can be provided with a seat body, a flushing component, a cover plate, a control device, etc. The automatic telescopic drying device can be installed on the cover plate or the seat body and is controlled by the control device to turn on or off the drying function.

[0059] [[ID=,18]]Under normal conditions, the telescopic rod group 40 is in a contracted state and the drying function is turned off. When the drying function is controlled to be turned on, the working principle is as follows:

[0060] The fan 20 and the heating unit 30 are started, and the high-speed fan begins to operate, extracting a large amount of air from the air inlet 11 and entering the heating unit 30. The air temperature is raised to a preset temperature and then enters the air outlet head 50 through the telescopic rod group 40. Since the area of the pushing area 52 is larger than that of the air outlet 51, most of the hot air is blown to the pushing area 52 to generate a thrust force, causing the air outlet head 50 to drive the second telescopic rod 44 to move outwards and extend. The hot air is ejected through the air outlet 51.

[0061] When it moves until its second limit projection 46 abuts against the second limit projection 46 of the first telescopic rod 43, the second telescopic rod 44 drives the first telescopic rod 43 to continue to move outwards and extend until the first limit projection 45 of the first telescopic rod 43 contacts and limits with the first limit projection 45 of the fixed sleeve 42.

[0062] During the movement of the telescopic rod group 40, the return member 60 is compressed. When it is fully extended, due to the sufficient length of the telescopic rod, the preheating is fast, and the air outlet 51 is closer to the buttocks. The hot air ejected through the air outlet 51 has a high wind speed and can quickly dry the buttocks.

[0063] When the drying is completed, the fan 20 and the heating unit 30 are turned off, and the thrust force generated by the wind pressure disappears. Under the action of the return member 60, the air outlet head 50 drives the second telescopic rod 44 to first retract outside the first telescopic rod 43, and the first telescopic rod 43 and the second telescopic rod 44 move synchronously and retract outside the fixed sleeve 42, and the drying is completed.

[0064] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification made to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
