Description

Technical Field

[0001] The utility model relates to the technical field of heating appliances, in particular to a flushable portable liquid heating appliance. Background Art

[0002] Portable liquid heating appliances on the market, especially portable electric milk frothers and portable hot water cups, have a traditional structure including a cup shell, a cup liner arranged in the cup shell, and a heating component for heating the cup liner, and the heating component is installed at the bottom of the cup shell. Due to mandatory safety regulations, portable heating appliances need to have a hole at the bottom to facilitate liquid drainage in order to pass safety regulations. This hole is usually in a normally open state. For this reason, if you want to clean the outer surface of the host, you can only wipe it with a cloth, and you cannot wash it with water under the faucet. If you wash it with water, water will flow into the inside of the host, causing electric shock or machine damage. Utility Model Content

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] According to the attached Figures 1 to 5As shown, the portable flushable liquid heating device of the utility model can be selected as an electric milk frother, a hot water cup and other liquid heating devices, which includes a cup shell 1 and a cup liner 2 arranged in the cup shell 1, and a heating component 3 for heating the cup liner 2. The heating component 3 is installed at the bottom of the cup shell 1, and the bottom of the cup shell 1 is provided with a through hole 4 for easy liquid discharge. Among them, the cup shell 1 is provided with an automatic opening and closing protection device that can automatically close or open the through hole 4. The automatic opening and closing protection device includes a telescopic push part 5 and a sealing member 6. The telescopic push part 5 is telescopically connected to the bottom of the cup shell 1, and the sealing member 6 is arranged at the lower part of the telescopic push part 5 and can be sealed and connected to the through hole 4 or separated from the through hole 4 as the telescopic push part 5 is telescopic.

[0018] Reference Figures 1 to 5 As shown, in further detail, the telescopic push part 5 includes a push rod 51, a spring 52, and a fixed cover 53. The fixed cover 53 is fixedly installed above the through hole 4, the upper part of the push rod 51 is slidably connected to the fixed cover 53, and the seal 6 is installed at the lower part of the push rod 51. The spring 52 is sleeved on the push rod 51, and the two elastic ends of the spring 52 are respectively pressed and connected to the fixed cover 53 and the seal 6, so that the elastic force of the spring 52 acts on the seal 6 to press downward and seal the through hole 4, or the external reaction force acts on the push rod 51 to move upward to compress the spring 52 and separate the seal 6 from the through hole 4.

[0019] The end of the push rod 51 passes through the through hole 4 and extends out of the bottom of the cup body 1 under the elastic action of the spring 52, or the end of the push rod 51 compresses the spring 52 under the action of the external reaction force to retract into the through hole 4.

[0020] That is, when the heating device is placed on a table for use, the end of the push rod 51 touches the table. At this time, the gravity of the heating device and the reaction force of the table act on the push rod 51, overcoming the elastic force of the spring 52 and compressing the spring 52 to push the push rod 51 upward, so that the end of the push rod 51 retracts into the through hole 4, thereby driving the seal 6 to disengage from the through hole 4, realizing automatic opening of the through hole 4, facilitating drainage when the heating device is in use, ensuring normal use of the heating device, and complying with industry regulations.

[0021] When the flushing state is lifted up, the elastic force of the spring 52 pushes the seal 6 downward, so that the seal 6 is pressed against the through hole 4 and sealed with the through hole 4, so that the through hole 4 is automatically closed, so that when the user lifts up the flushing, water will not flow into the inside of the machine, and no safety problem will be caused. The product is reliable and practical, ensuring the quality of use of the product.

[0022] Reference Figures 1 to 5As shown, in the optimized solution, the fixed cover 53 is provided with a guide hole 54 for facilitating the upper portion of the push rod 51 to slide up and down. Under the action of the guide hole 54, the push rod 51 is effectively directed to extend upward or downward from the through hole 4 or retract into the through hole 4, thereby improving the stability of the structural operation and ensuring the normal use of the product.

[0023] Furthermore, a fixing portion 55 for preventing the seal 6 from being separated is provided at the lower portion of the push rod 51 , and the seal 6 is mounted on the fixing portion 55 .

[0024] The sealing member 6 is provided with inclined surfaces 61 on both sides thereof, and the inclined surfaces 61 are gradually pressed downwards and sealed at the end of the through hole 4 under the elastic action of the sealing member 6 .

[0025] The cooperation between the sealing member 6 and the fixing portion 55 of the present structure can facilitate the disassembly and assembly of the sealing member 6, and is easy to maintain and replace, thereby further improving the sealing performance of the device.

[0026] The above-mentioned specific embodiments are only specific implementation methods with better effects of the present utility model. Any structure that is the same or equivalent to the flushable portable liquid heating device of the present utility model is within the protection scope of the present utility model.
