Description

Technical Field

[0001] The utility model relates to the technical field of hot water kettles, in particular to a liquid heater device without residual water. Background Art

[0002] The electric kettle comprises a kettle body and a power socket. Some feature-rich electric kettles will be equipped with a micro water pump on the power socket to realize the function of automatic water discharge, without having to take out the kettle to pour water. In order to prevent tea, wolfberry, red dates and other brewing products in the kettle from clogging the water pump, a filter will be set at the bottom of the kettle, but the setting of the filter will form a step-like protrusion upward inside the kettle body, blocking part of the water flow. When the water pump draws water, there will be residual water in the kettle that cannot be pumped out. Utility Model Content

[0003] The purpose of the utility model is to provide a liquid heater without residual water device to solve the problems raised in the above background technology.

[0004] To achieve the above object, the utility model provides the following technical solution: a liquid heater device without residual water, comprising an inner tank, a bottom cover welded to the lower end of the inner tank, a concave portion provided on the edge of the surface of the bottom cover, a filter mesh hole provided on the surface of the concave portion, and the concave portion is used to guide the water in the inner tank to flow out through the filter mesh hole;

[0005] The inner tank and the bottom cover are first connected and then welded to avoid gaps between the inner tank and the bottom cover, which prevents some tiny substances from being hidden in the inner tank and facilitates cleaning of the inner tank.

[0006] A water guide ring is placed in the inner tank and connected to the upper surface of the bottom cover. A drain port is provided on the surface of the water guide ring, and a recessed portion is located inside the drain port. The thickness of the water guide ring decreases gradually along the direction of its axis to the drain port, so that the water in the inner tank can be guided to the drain port to avoid residual water in the inner tank.

[0007] Furthermore, a neck is provided at the upper end of the inner liner, and a folded edge is provided at the upper end of the neck, which is connected to the outer shell of the kettle via the folded edge, thereby improving the stability of the connection, and the outer shell of the kettle and the inner liner are not easy to loosen.

[0008] Furthermore, a raised portion is provided in the middle of the bottom cover surface, and the raised portion is inclined, and the inclination of the raised portion corresponds to the concave portion. When the water in the inner tank reaches the bottom, all the water flows toward the concave portion.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] (1) By providing a concave portion on the bottom cover, water can flow into the water outlet pipe without hindrance. The water guide ring and the raised portion cooperate to guide the water at the bottom of the inner tank into the concave portion, thereby reducing the residual water in the kettle, preventing the kettle from being in a warm and humid environment, and reducing the risk of bacterial growth.

[0011] (2) The water is filtered through the filter holes. The micro water pump can pump water after being connected to the water outlet pipe. The water in the kettle can be pumped out by the suction force of the micro water pump. The outer shell of the kettle is clamped by the folded edge. When the kettle is used for a long time, the outer shell and the inner liner are not easy to loosen, and the kettle is more durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example:

[0020] See also Figure 1-5 The utility model provides a technical solution: a liquid heater without residual water device, comprising an inner tank 1, a bottom cover 5 is welded at the lower end of the inner tank 1, a concave portion 6 is provided on the surface edge of the bottom cover 5, a filter mesh hole 7 is provided on the surface of the concave portion 6, and the concave portion 6 is used to guide the water in the inner tank 1 to flow out through the filter mesh hole 7;

[0021] The inner tank 1 and the bottom cover 5 have the same diameter and can be aligned and welded to avoid a gap at the joint between the inner tank 1 and the bottom cover 5, thereby preventing water from remaining. The filter holes 7 on the surface of the lower concave portion 6 are formed when the bottom cover 5 is stamped, and no bulge is formed on the bottom cover 5, which is conducive to water flowing in and out of the water pipe 4;

[0022] The water guide ring 9 is placed in the inner tank 1 and connected to the upper surface of the bottom cover 5. The surface of the water guide ring 9 is provided with a drain port 10, and the lower concave portion 6 is located inside the drain port 10. The thickness of the water guide ring 9 along the direction of its axis to the drain port 10 decreases successively. Figure 3 and Figure 4 As shown, the thicker part of the water guide ring 9 is far away from the lower recess 6 , and the thinner part of the water guide ring 9 is close to the lower recess 6 , guiding the water to flow to the lower recess 6 .

[0023] In this embodiment, if Figure 1 As shown, a neck 2 is provided at the upper end of the inner liner 1, and a folded edge 3 is provided at the upper end of the neck 2. The neck 2 and the inner liner 1 are integrally formed, and the folded edge 3 is used to connect with the kettle shell to avoid looseness between the kettle shell and the inner liner 1.

[0024] In this embodiment, if Figure 1 and Figure 2 As shown, a raised portion 8 is provided in the middle of the surface of the bottom cover 5, and the raised portion 8 is inclined. The inclination of the raised portion 8 corresponds to the recessed portion 6. The raised portion 8 is formed by stamping on the bottom cover 5, which can avoid water remaining on the raised portion 8 and facilitate water to flow to the recessed portion 6.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, a water outlet pipe 4 is welded on the lower surface of the bottom cover 5, and the water outlet pipe 4 covers the filter mesh hole 7. The water outlet pipe 4 is used to discharge the water in the inner tank 1 and is conveniently connected to the micro water pump.

[0026] Specifically, when in use, the water guide ring 9 is inclined toward the recessed portion 6, and the raised portion 8 of the bottom cover 5 is also inclined toward the recessed portion 6, so that the inner tank 1 is in an inclined state. When the water in the inner tank 1 is about to reach the bottom, the water guide ring 9 and the raised portion 8 guide the water to the location of the drain port 10, and then the water flows into the water outlet pipe 4 after being filtered by the filter mesh 7, thereby reducing the residual water in the kettle.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
