The spout in this case is made of ceramics, and in the drainage zone interval, avoid glazing to increase capillary action.

Regarding the structure and function of the boost structure of the present invention, please refer to the illustrations as follows:

First, please refer to Figure 1. The pot body 10 is a device for dispensing drinks, such as a teapot or a coffee pot. A spout 20 is diagonally provided on one side of the pot body 10, and the end of the spout 20 is a spout. 21. The lower edge of the spout 21 is the incised lip 22. The center of the spout 20 when viewed from the front is a midline S. The lower edge of the incisal lip 22 is the chin 230. The lower end of the chin 230 is connected to a defined throat 23. On the chin A drainage structure 60 is implemented at the position of 230 and the throat 23. The drainage structure 60 includes a drainage belt 61 connected to the lower edge of the cutting lip 22, and a drainage slot 62 leading to the inside of the spout 20. The drainage belt 61 and the drainage belt 62 The recessed holes 62 are arranged directly up and down along the center of the center line S.

The draw-back slot hole 62 can be a single hole or a double hole arranged on the left and right, and the opening structure of the draw-back slot hole 62 is an upright slot shape or a hole shape.

The surface of the drainage belt 61 is provided with a rough surface structure. During production, it can be made into a roughened surface or a glaze with a rough surface is applied, so that the surface of the drainage belt 61 can provide water droplets to adhere to the water-liquid surface. For the adhesion function, the surface of the drainage belt 61 and the chin 230 are of the same body, or the spout 20 is made of ceramic material. Glazing can be avoided in the area of the drainage belt 61 to expose the rough surface of the clay and increase the capillary function, which can provide water droplets with a better adhesion effect.

The above-mentioned drainage belt 61 is a strip-shaped area, the upper end is connected to the lower edge of the incision lip 22, and the lower end is connected to the return slot 62. Its area shape can be a strip shape or an inverted triangle area shape, and the bottom edge of the triangle is connected. To the cutting lip 22, the top corner connects to the location of the drawback slot 62.

Please refer to Figure 2 again. The pot 100 is composed of a pot body 10 with a spout 20 on one side and a spout 20 on the other. There is a handle 40 on the side, and the lid 30 can be used to seal the pot above. By lifting the handle 40, the tea inside is dispensed into the teacup 200, and the tea is discharged through the spout 21.

Please refer to Figure 3 again. After the tea soup is dispensed, the user uses the handle 40 to place the pot 100 on the table 300 so that the bottom 25 of the pot 100 rests on the table, which is defined as a horizontal seat. Due to the cohesion and adhesion of the water droplets, after the dispensed water column is cut through the incision lip 22, there will be a residual droplet 50 of the dispensed water attached to the chin 230. The residual droplet 50 is located on the chin as shown in Figure 1. In the interval of 230, the surface of the drainage belt 61 has a rough surface structure and is temporarily adsorbed. The residual droplets 50 will fall downward under the action of gravity and form a spreading flow. The residual droplets 50 will spread downward to the lifting structure 60. The outer port of the suck-back slot hole 62 is provided, and the suck-back slot hole 62 is pore or slot-shaped to produce capillary action, so as to suck in the residual drops 50 flowing down and flow back into the inner tube body 26 in the opposite direction. Stored in the kettle body 10, the direction of the return flow is also pulled by the angle of the groove bottom 600. The groove bottom 600 is located at the lower edge of the return slot hole 62, and is at least horizontal when the kettle 100 is aligned, and the inner There will be a layer of water film remaining on the inner surface of the pipe body 26 due to the previous dispensing. This water film will intersect with the water sucked in from the return slot 62 due to cohesion, and then the surface of the inner pipe body 26 will tilt downward. Then a sliding effect is produced, allowing the residual drops 50 to flow into the inner tube body 26 through the adsorption of the suck-back slot hole 62 and flow back into the interior of the pot body 10, thereby preventing the residual drops 50 from being contaminated with the belly 24.

If the kettle 100 is a ceramic product and the inside of the inner tube body 26 is not glazed in some implementations, the water film will form a larger rough surface, providing a larger thickness or volume of the abrasive layer of the water film that will remain after dispensing. , and there is enough volume to interact with the water sucked in from the suction slot 62. After the water is accumulated through the cohesion and interaction of the water body, the force of gravity traction occurs, and the residual drops 50 of this part are reflected back to the inside of the pot body 10. Return to Ji.

Please refer to Figures 4 and 5 again. Please refer to Figure 4 first. The lifting structure 60 is located at the lower surface position of the lower edge of the lip 22 of the mouth 21 of the spout 20. This position includes a chin. 230 and a throat 23. Based on the midline S, an upper and lower belt-shaped drainage belt 61 is provided parallel to the chin 230. The bottom edge 610 of the drainage belt 61 includes the bottom edge 620 of the suck-back slot 62. In this way, the water dripping down from the incision lip 22 will move downward through the adsorption effect of the drainage belt 61 and the gravity of the center of gravity. The flow spreads to the opening of the suck-back slot hole 62, and is sucked back toward the inside of the spout 20 by the capillary action formed by the opening space of the suck-back slot hole 62.

Please refer to Figure 5 again. The bottom of the drainage belt 61 is a bottom edge 610, and the bottom of the drain hole 62 is a bottom edge 620. The two penetrate inward to form a complete groove bottom 600.

The horizontal line L is defined as when the pot 100 (as shown in Figure 3) is placed on the table 300, the angle of the groove bottom 600 formed by the bottom of the slot hole 62 is at least the same as the horizontal line L. Or tilt it at an angle below the inner bottom of the inner tube body 26, so that the residual droplets 50 temporarily collected on the chin 230 can easily form a directivity due to the inclination of the groove bottom 600, and then be sucked back down in the opposite direction. Enter the inner bottom of the inner tube body 26, where the groove bottom 600 is formed by opening the pull-back slot hole 62. If it is processed manually, there will be deviations due to the operation, so the groove bottom 600 is not a standard straight line, but With the overall average being a straight line, the water liquid can also be provided to fall downward inside the inner tube body 26, and the bottom of the tank 600 can also form a downward slope curve groove W with a large slope inward, and a downward slope curve groove W. It may also be curved due to processing deviation or intentional production.

Please refer to Figure 6 again. The pull-back slot 62 leads inward to one end of the inner tube body 26. An outer inclined groove 64 and an inner inclined groove 63 can be provided up and down respectively. The function of the inner inclined groove 63 can provide The residual droplets 50 reach the outer port of the pump-back slot 62 from the position of the drainage belt 61 by gravity, and are affected by the capillary adsorption of the pump-back slot 62 and the interaction of the water film remaining on the inner surface of the inner tube body 26. The inner bottom of the inner tube body 26 is retracted in the opposite direction, and the inner inclined groove 63 is turned into a large slope, and the thickness T of the pipe wall of the spout 20 located in the retraction slot hole 62 is reduced, so that the remaining drops 50 can easily cross the short slot. The inner bottom of the inner tube body 26 can be easily drawn back to the bottom 600 in the reverse direction.

Please refer to Figure 7 again. The outer inclined groove 64 provided in the suction slot hole 62 allows the liquid to be released from the inner tube body 26 to the direction of the tube opening 21 during dispensing. A first force F is generated through the action of the water flow. This flow After the force F impacts the surface of the outer inclined groove 64, an oblique force will be formed, that is, the flow force F will produce a component force F1 in the direction of drawing back the slot hole 62, and a similar siphon effect, so The water flow released from the inside of the inner tube body 26 is not easy to leak out from the direction of the return slot hole 62 .

Please refer to Figure 8 again. In another embodiment of the present invention, the drainage belt 61 of the lifting structure 60 is opened in a concave manner. The groove surface from the front angle can be an upright or V-shaped groove surface. According to the center line S, The center is concave from the lower edge of the cutting lip 22 downward to the bottom of the throat 23, and is connected to the bottom edge 620 of the return slot 62. The bottom edge 610 and the bottom edge 620 penetrate inwards to form a groove bottom 600. The drainage belt 61 and the suck-back slot 62 can be further configured as two flat channels on the left and right (not shown in the figure) to increase the capacity for reverse absorption of water liquid.

Please refer to Figure 9 again (please cooperate with Figure 8). The drainage belt 61 is in the shape of a groove. The front can be an upright or V-shaped groove. The top of the side section is pointed and the bottom is a bottom edge 610. , the bottom edge 610 and the bottom edge 620 of the opened drain hole 62 together form a groove bottom 600. The groove bottom 600 can be at least horizontal, or inclined downward toward the bottom of the inner tube body 26. In the drain groove The hole 62 is opened inward to connect one end of the inner tube body 26, and an outer inclined groove 64 and an inner inclined groove 63 are respectively provided up and down. The outer inclined groove 64 and the inner inclined groove 63 have the operating functions as shown in Figures 6 and 7 respectively.

The drainage belt 61 is formed into a groove shape, and the bottom edge 610 occupies the outer opening of the suction slot 62, so that the depth of the suction slot 62 is shortened, and the tank space of the drainage belt 61 can accommodate a larger amount of water temporarily attached to the chin 230. liquid, so that the remaining drops 50 can be quickly and massively collected in the space of the drainage belt 61, and are reversely drawn back into the inner bottom of the inner tube body 26 by the action of the draw-back slot hole 62, and then the remaining drops 50 can be collected by the slope of the inner inclined groove 63. 50 can slide down quickly, so that the residual drop 50 can increase the front and rear traction force, wherein the bottom 600 of the groove can be horizontal, or can be opened with a slope toward the inner bottom of the inner tube body 26 .

Please refer to Figure 10 again (this figure is a cross-sectional view of the relevant lifting structure 60 in Figure 8). The outer end of the lifting slot 62 is connected to the drainage belt 61, which is straight groove-shaped and has two sides. It can be parallel or tapered inward, so the pull-back slot 62 opens wide to the outside, increasing the volume space for temporarily accumulating water. The position of the pull-back slot 62 is parallel and centered along the center line S. And the establishment of the drainage belt 61 can be processed twice or formed simultaneously during the production process of the spout 20. The surface of the drainage belt 61 can also be glazed to make the appearance of the spout 20 more integrated.

Please refer to Figure 11 again. Another embodiment of the lifting structure 60 of the present invention is a trumpet-shaped trough structure. The position of the throat 23 of the spout 20 is based on the center line S, and a center is provided toward the spout 20. The inner tapered eccentric tapered suck-back slot hole 62 is located at the throat 23. The upper edge of the suck-back slot hole 62 is upward relative to the chin 230 position of the incisal lip 22 area, and is provided with an eccentric inclined opening. The drainage belt 61 is in the shape of an elliptical bellmouth. The drainage belt 61 is connected to the pull-back slot 62. The cross-sectional shape of the pull-back slot 62 may be round hole-shaped or upright slot-shaped.

Please refer to Figure 12 again. The pull-back slot hole 62 is in the shape of a tapered cone hole. In addition to the circular cone hole, the cross section of the cone hole can also be an upright oval cone hole, with its long axis parallel to the kettle. The center line of the mouth 20, the bottom of the suck-back slot 62 is a groove bottom 600, the groove bottom 600 is at least flush with the horizontal line L, or inclined downward toward the inner bottom of the inner tube body 26, outside the suck-back slot 62 The end is toward the chin 230 direction of the incisal lip 22, and is connected to a trumpet-shaped drainage belt 61 with an eccentric cone. The two surfaces of the drainage belt 61 and the pull-back slot 62 are connected in a curve, and the bottoms of the drainage belt 61 and the pull-back slot 62 are curved. A groove bottom 600 is constructed, and the water droplets are formed into a ball shape by the cohesion of the water droplets. The drainage belt 61 and the return slot hole 62 designed in this way can cope with the appearance of ball-shaped water droplets, and can easily accept the water droplets flowing down from the cutting lip 22. 50 remaining drops.

The groove bottom 600 of the pull-back groove hole 62 may also form a curved downward-inclined curved groove W with a large slope toward the bottom of the inner tube body 26 .

Please refer to Figure 13 again. The pull-back slot hole 62 is a tapered hole that tapers toward the inner tube body 26. The inner end is connected to the inner surface of the inner tube body 26 at one end. The upper and lower ends can be selected or provided separately. There are an outer inclined groove 64 and an inner inclined groove 63. The functions of the outer inclined groove 64 and the inner inclined groove 63 are the same as those in Figures 6 and 7.

In the present invention, a drainage belt is planned in the mandibular interval between the incised lip and the throat.
