[0036] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention is further explained below in conjunction with the accompanying drawings and embodiments. At the same time, it is stated that the embodiments described below are only used to explain the present invention and are not used to limit the present invention.

[0037] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0038] The directions or positions indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top”, “bottom”, “inside” and “outside” are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and are not to be construed as limitations on the present technical solution.

[0039] The terms "first" and "second" are only used for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0040] like Figure 1 and Figure 2 As shown, a heating mechanism of a drip coffee machine includes a control host 12, a heating component and a water diversion component. The control host 12 is provided with a power supply and a start switch 1201. The upper and lower ends of the control host 12 are each provided with a bracket, including an upper bracket 4 and a lower bracket 7. The heating component and the water diversion component are fixedly connected to the side of the control host 12 through the two brackets. The start switch 1201 is located at the top of the control host 12. The start switch 1201 is electrically connected to the power supply and the working mainboard, so that the user can press and turn on the power supply to provide working voltage for the heating component.

[0041] like Figure 3As shown, the heating assembly includes a coated glass bottle 1, an upper conductive copper hoop 2 and a lower conductive copper hoop 5. The upper end of the outer side of the bottle body of the coated glass bottle 1 is connected to the upper conductive copper hoop 2, and the lower end of the outer side of the bottle body is connected to the lower conductive copper hoop 5. In the area between the upper conductive copper hoop 2 and the lower conductive copper hoop 5, the outer wall surface of the coated glass bottle 1 is plated with a layer of transparent resistance coating. When the resistance coating is applied, it is necessary to cover the wall surface position where the two conductive copper hoops are located, so that the resistance coating connects the upper conductive copper hoop 2 and the lower conductive copper hoop 5.

[0042] The upper conductive copper hoop 2 and the lower conductive copper hoop 5 are connected to the power supply in the control host 12, and one is connected to the positive pole and the other is connected to the negative pole. When the start switch 1201 is pressed to turn on the power, the power supply, the upper conductive copper hoop 2, the resistance coating and the lower conductive copper hoop 5 form a loop, the resistance coating is energized to generate heat, and the water in the coated glass bottle 1 is heated until the water boils. The present invention uses the resistance coating to generate heat, and the preheating time is shorter than that of the traditional electric heating tube. Since the resistance coating wraps the coated glass bottle, its heating area is large, the heat conversion efficiency is high, and the power consumption is reduced.

[0043] In a preferred embodiment, both ends of the coated glass bottle 1 protrude from the conductive copper hoops on both sides, that is, the conductive copper hoops at both ends of the coated glass bottle 1 leave a certain distance from the edge of the bottle, so that the conductive copper hoops can better contact with the coated glass bottle 1, thereby ensuring both conductivity and sealing.

[0044] like Figure 3 and Figure 4 As shown, the heating assembly further includes a transparent heat-insulating cover 10, which is arranged outside the coated glass bottle 1, and a gap is left between the heat-insulating cover 10 and the coated glass bottle 1. The upper end of the heat-insulating cover 10 is connected to the upper bracket 4, and the lower end of the heat-insulating cover 10 is connected to the lower bracket 7. Specifically, the inner wall surfaces of the upper bracket 4 and the lower bracket 7 are provided with a snap-on groove 401, and the heat-insulating cover 10 is in a hollow cylindrical shape, and plug-in ports are provided at both ends thereof, and a snap-on convex ring 1001 is provided on the outer wall surface of the plug-in port, so that the two ends of the heat-insulating cover 10 can be respectively inserted into the upper bracket 4 and the lower bracket 7, and fixed by the snap-on groove 401 and the snap-on convex ring 1001.

[0045] The use of a transparent heat shield can ensure that the heat shield does not affect the visualization of the heating process inside the heating mechanism. The heat shield can also prevent the heat generated by the resistance coating from diffusing outward, limit the heat within a certain range, and increase the heating rate of the resistance coating, thereby further shortening the preheating time and greatly increasing the heating rate; at the same time, the heat shield also increases the upper temperature limit that the resistance coating can reach, generating more heat, and the water in the coated glass bottle is more likely to boil.

[0046] The upper bracket 4 and the upper conductive copper hoop 2 are at the same level, the lower bracket 7 and the lower conductive copper hoop 5 are at the same level, the first silicone ring 3 is filled between the upper bracket 4 and the coated glass bottle 1, the first silicone ring 3 wraps the upper end of the coated glass bottle 1, and realizes the fixed connection between the upper conductive copper hoop 2 and the coated glass bottle 1. Similarly, the second silicone ring 6 is filled between the lower bracket 7 and the coated glass bottle 1, and the lower conductive copper hoop 5 is fixed to the bottle body of the coated glass bottle 1 through the second silicone ring 6. In this embodiment, the inner sides of the first silicone ring 3 and the second silicone ring 6 are both provided with mounting grooves for fixing the conductive copper hoop.

[0047] The plug-in ports at both ends of the heat insulation cover 10 are located between the silicone ring and the bracket, for example, the upper plug-in port of the heat insulation cover 10 is located between the upper bracket 4 and the first silicone ring 3, and the lower plug-in port of the heat insulation cover 10 is located between the lower bracket 7 and the second silicone ring 6. Therefore, the first silicone ring and the second silicone ring also play a role in sealing the two ends of the heat insulation cover, reducing heat loss, thereby further improving the heat conversion efficiency of the heating mechanism.

[0048] The material of the heat insulation cover has poor thermal conductivity and has a certain wall thickness. When the resistance coating is powered on and heated, the outer wall temperature of the heat insulation cover is not high. Therefore, the setting of the heat insulation cover is also beneficial to protect users and prevent users from accidentally touching the high-temperature resistance coating and getting burned.

[0049] The water diversion and outlet assembly of the present invention comprises a silicone plunger 8, a diversion tube 9 and a drip shower head 11. The silicone plunger 8 is arranged at the opening of the coated glass bottle 1. The silicone plunger 8 seals the opening of the coated glass bottle 1, leaving only a through hole at the center of the silicone plunger 8, which is used to pass through the diversion tube 9. One end of the diversion tube 9 passes through the silicone plunger 8 and is inserted into the coated glass bottle 1, and the other end is located outside the coated glass bottle 1, with the nozzle of this end facing downward, so that the water in the coated glass bottle 1 can flow out of the coated glass bottle 1 through the diversion tube 9.

[0050] The opening of the coated glass bottle 1 is trumpet-shaped, which is convenient for the user to insert or remove the silicone plunger 8. After the silicone plunger 8 is inserted, it is tight and firm, which greatly increases the air tightness inside the coated glass bottle 1 and facilitates the boiling water inside to flow out from the guide tube 9.

[0051] The flow guide tube 9 is U-shaped, and the length of the glass tube on one side of the U-shaped flow guide tube 9 is longer than that of the glass tube on the other side. The longer glass tube is inserted into the coated glass bottle 1 through the through hole of the silicone plunger 8, and the shorter glass tube is connected to the drip shower 11.

[0052] When the water in the coated glass bottle 1 boils, the pressure in the coated glass bottle 1 increases, and the boiling water enters from the longer glass tube opening under the pressure, flows out from the other glass tube, and passes through the drip shower 11. The drip shower 11 is provided with a plurality of drip holes, and the boiling water forms a plurality of uniform dripping water columns after passing through the drip shower 11.

[0053] In the present invention, the resistance film layer of the coated glass bottle is transparent, ensuring that the coated glass bottle is transparent, and the guide tube is also transparent, so the entire heating process and boiling process of the water inside the coated glass bottle are visible. The user can directly observe the gradual boiling of the water and the entire process of hot water dripping, and better grasp the time when the heating mechanism discharges water, thereby improving the user experience.

[0054] The silicone plunger 8 is also provided with one or more air guide holes 801 for taking in air and pressing the water in the coated glass bottle out of the guide tube.

[0055] On the other hand, the heating mechanism of the present invention completes filling and boiling water through the coated glass bottle 1. The coated glass bottle 1 has a large bottle mouth and bottle body, a simple structure, and is very easy to disassemble and clean. It can prevent the coated glass bottle 1 from generating scale on the bottle wall after long-term use, thereby affecting the visualization effect.

[0056] In a preferred embodiment, the inner diameter of the flow guide tube 9 is one eighth to one fifth of the inner diameter of the coated glass bottle 1 , which not only ensures the water outlet speed and efficiency of the flow guide tube 9 , but also makes the inside of the flow guide tube 9 easy to clean.

[0057] like Figure 5 As shown, the present invention also provides a visual drip coffee machine, including a base 13, a coffee cup 14 and a funnel 15, and also includes the heating mechanism of the above scheme, the heating mechanism and the coffee cup 14 are arranged on the base 13, and the coffee cup 14, the funnel 15 and the drip shower 11 of the heating mechanism are aligned from bottom to top.

[0058] In an optional embodiment, the base 13 includes a cup seat and a host seat. The coffee cup 14 is placed on the cup seat. The control host 12 of the heating mechanism is set on the host seat. A cylindrical fixing rod 16 is provided on the host seat. The control host 12 is connected to the fixing rod 16, thereby raising the height of the entire heating mechanism.

[0059] A funnel bracket is provided on the fixing rod 16, and the angle of the funnel bracket on the fixing rod 16 is adjustable. The position of the funnel bracket is higher than the height of the coffee cup 14, and the funnel 15 is installed on the funnel bracket, so that the drip shower head 11 of the heating mechanism is located above the funnel 15, and the funnel 15 is located above the coffee cup 14. By rotating and adjusting the funnel bracket, it is convenient to take and put the coffee cup.

[0060] When using the visual drip coffee machine of the present invention, first open the silicone plunger 8 of the coated glass bottle 1, fill a proper amount of water into the coated glass bottle 1, and plug the silicone plunger 8; first place the coffee cup 14, and then install and adjust the height of the funnel 15; put filter paper in the funnel 15, and pour in coffee powder; rotate the guide tube 9 on the coated glass bottle 1 to align the guide tube 9 with the funnel 15; press the start switch 1201 to turn on the power for heating.

[0061] It can be observed that the water in the coated glass bottle gradually boils. As the temperature rises, when a certain pressure is reached in the coated glass bottle, water flows out from the guide tube, drips into the coffee powder in the funnel through the drip shower head, and the funnel drips coffee. It can be seen that the entire working process of the coffee machine of the present invention, such as the gradual boiling of water, the outflow of water, and finally the dripping of coffee from the funnel, is visualized, which greatly improves the user experience.

[0062] On the other hand, the drip coffee maker of the present invention has a visualization effect by setting the heating mechanism of the above scheme, and is different from the visualization of the existing coffee maker. The visualization of the existing coffee maker only observes the solution in the water tank, while the visualization of the present invention, because the coated glass bottle integrates water filling and water boiling, includes visualization of water inventory, visualization of the entire water heating process, and visualization of the water discharge process after boiling.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
