Background

This section provides only background information related to the present utility model so as to enable those skilled in the art to more thoroughly and accurately understand the present utility model, and is not necessarily prior art.

At present, the electric coupler is widely applied to an electric heating thermos bottle and comprises an upper coupler and a lower coupler, wherein a plurality of annular metal electrodes are uniformly distributed on the upper coupler and the lower coupler, and the upper coupler is inserted into the lower coupler and is in electric communication by the contact of the corresponding metal electrodes. The electric coupler not only can separate the upper coupler from the lower coupler to realize the separation of the kettle body and the base, but also can be inserted from any direction at the bottom of the kettle body and is matched with the base, and the electric coupler is very convenient to use.

With the continuous improvement of the living standard of people, consumers put higher demands on the electric thermos bottle, and people hope to realize automatic control of the water outlet of the electric thermos bottle. For this purpose, some merchants have an upper water inlet pipe arranged in a central opening of the upper coupler, an upper valve core connected with a spring arranged in the upper water inlet pipe, a lower water inlet pipe arranged in a central opening of the lower coupler, and a lower valve core connected with the spring arranged in the lower water inlet pipe. Therefore, when the upper coupler and the lower coupler are coupled and connected, the upper valve core and the lower valve core are mutually propped so that the upper water inlet channel and the lower water inlet channel are communicated, and water outlet can be realized; when the upper coupler and the lower coupler are separated, the upper valve core and the lower valve core are reset and move through springs to seal the upper water inlet channel and the lower water inlet channel respectively. However, the following problems still remain with the above arrangement: firstly, the upper valve core realizes the on-off of an upper water inlet channel through the spring reset movement, and the difficulty is increased for the installation of the upper valve core; secondly, the upper valve core and the lower valve core are mutually propped to enable the upper water inlet channel to be communicated with the lower water inlet channel, so that the control of the elastic force and the stress direction of the two springs is difficult, and the springs are easy to twist or deform to cause elastic failure; finally, the sealing between the upper valve core and the upper water inlet pipe and the sealing between the lower valve core and the lower water inlet pipe are difficult to control, and if the sealing is not tight, the problem of water leakage is caused, and even the electrical components are burnt out.

Therefore, how to provide an electrothermal thermos with a simple water outlet structure and convenient control operation is a technical problem to be solved by the technicians in the field.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Example 1

Referring to fig. 1 to 8, the present utility model firstly provides a water connector, comprising an upper water inlet assembly 1 and a lower water inlet assembly 2, wherein the upper water inlet assembly 1 comprises an upper water inlet pipe 11 formed with an upper water inlet channel, a first sealing ring 12 arranged at the bottom of the upper water inlet channel and an upper valve core 13 movably arranged in the upper water inlet channel, and the upper valve core 13 moves downwards under the action of gravity and abuts against a port of the first sealing ring 12 to seal the upper water inlet channel; preferably, the upper valve core 13 is a steel ball. The lower water inlet assembly 2 at least comprises a lower water inlet pipe 21 formed with a lower water inlet channel and a shaft body 22 arranged in the lower water inlet channel, when the upper water inlet pipe 11 extends into the lower water inlet channel and reaches a certain position, the upper valve core 13 is jacked by the shaft body 22 to open the upper water inlet channel, as shown in fig. 7.

Thus, when the upper water inlet pipe 11 is separated from the lower water inlet pipe 21, the port of the first sealing ring 12 can be blocked by the natural gravity of the upper valve core 13 to seal the upper water inlet channel, so that the residual water in the upper water inlet channel is prevented from overflowing and dripping down. In addition, due to the fact that the mode of matching the spring with the upper valve core 13 is omitted, the use of the spring is reduced, structural arrangement of the upper water inlet pipe 11 and the upper valve core 13 for installing the spring is avoided, and fitting cost and production cost are greatly reduced. In addition, the upper valve core 13 is jacked up by the shaft body 22 arranged in the lower water inlet pipe 21 to open the upper water inlet channel, so that the operation is simple and the control is easy.

Referring to fig. 2-3, specifically, the top and bottom of the upper water inlet pipe 11 are respectively provided with a first water inlet 111 and a first water outlet 112 which are communicated with the upper water inlet channel, and the first sealing ring 12 is arranged in the upper water inlet channel and is close to the first water outlet 112; the filter screen 14 is further disposed above the first water inlet 111, the filter screen 14 includes a circular plate portion 141 and a surrounding portion 142 disposed around the bottom of the outer edge of the circular plate portion 141, a plurality of small holes 1411 are formed in the circular plate portion 141, and a plurality of large holes 1421 are disposed around the junction of the circular plate portion 141 and the surrounding portion 142.

Therefore, when the upper water inlet assembly 1 is arranged at the bottom of the inner container 7 of the electric heating thermos flask, the circular plate part 141 of the filter screen 14 is provided with a plurality of small holes 1411, so that larger scale or solid particles remained in the water of the inner container 7 can be filtered out, and the water can be prevented from entering the upper water inlet pipe 11 or the lower water inlet pipe 21 to cause blockage. Because the diameter of the small holes 1411 is small, water at the bottom of the inner container 7 easily forms a water film on the small holes 1411, and when the water level at the bottom of the inner container 7 is low, water at the bottom of the inner container 7 cannot smoothly flow into the upper water inlet passage through the small holes 1411. Therefore, the connection between the circular plate 141 and the enclosure 142 is provided with a plurality of large holes 1421, so that the water at the bottom of the liner 7 can smoothly flow into the upper water inlet pipe 11 through the large holes 1421. In addition, when the water at the bottom of the inner container 7 is heated to a boiling state, a plurality of bubbles generated by the water can be smoothly discharged through a plurality of large holes 1421.

Referring to fig. 4-5, the lower inlet assembly 2 further includes a second sealing ring 23 disposed at the top of the lower inlet passage and a first lower valve core 24 movably disposed in the lower inlet passage. Specifically, the top of the lower water inlet pipe 21 is provided with a second water inlet 212 communicated with the lower water inlet channel, and the second sealing ring 23 is sleeved on the second water inlet 212; a partition plate 211 is arranged in the middle part of the lower water inlet pipe 21, and a plurality of second water outlets 2111 communicated with the lower water inlet channel are annularly arranged on the partition plate 211. In addition, a first elastic member 25 is further disposed in the lower water inlet channel, a protruding edge 241 extends downward from the top of the first lower valve core 24, the first elastic member 25 is sleeved on the protruding edge 241, the top of the first elastic member abuts against the first lower valve core 24, and the bottom of the first elastic member abuts against the partition 211. Therefore, under the elastic force of the first elastic member 25, the first lower valve core 24 can be driven to abut against the port of the second sealing ring 23 so as to seal the second water inlet 212 of the lower water inlet channel. Preferably, the first elastic member 25 is a spring.

In this embodiment, the middle part of the first lower valve core 24 is provided with a avoiding hole through which the shaft body 22 can pass.

Thus, when the upper water inlet pipe 11 extends into the lower water inlet channel, the upper water inlet pipe 11 abuts against the first lower valve core 24 and drives the lower water inlet pipe to move downwards against the elastic action of the first elastic piece 25 so as to open the lower water inlet channel, as shown in fig. 6; until the upper spool 13 is lifted up by the shaft body 22, the upper water inlet passage communicates with the lower water inlet passage, as shown in fig. 7. When the upper water inlet pipe 11 extends into the lower water inlet channel, the outer side wall of the upper water inlet pipe 11 is abutted against the inner side wall of the second sealing ring 23 to form a waterproof seal.

Therefore, when the lower water inlet assembly 2 is arranged on the base 5 of the electric heating thermos bottle and the upper water inlet pipe 11 is separated from the lower water inlet pipe 21, the first lower valve core 24 can be driven to abut against the port of the second sealing ring 23 under the elastic action of the first elastic piece 25 so as to seal the second water inlet 212 of the lower water inlet channel, so that residual water in the lower water inlet channel is prevented from overflowing and dripping into the base 5, and the water is prevented from invading the electrode to cause leakage danger. In addition, when the upper water inlet pipe 11 stretches into the lower water inlet channel, the outer side wall of the upper water inlet pipe 11 is in contact with the inner side wall of the second sealing ring 23 to form a waterproof seal, so that the water leakage phenomenon is prevented when the upper water inlet pipe 11 stretches into the lower water inlet channel, and the tightness is further improved.

Specifically, the shaft body 22 is further provided with a collar 221 to form a step surface, and a groove 2112 is further protruding in the middle of the partition 211; the shaft body 22 is further provided with a second elastic member 29, and one end of the second elastic member 29 is abutted against the bottom of the collar 221, and the other end is abutted against the bottom of the groove 2112 of the spacer 211. Preferably, the second elastic member 29 is also a spring.

Therefore, under the elastic force of the second elastic member 29, the movable shaft 22 moves upward to drive the second lower valve core 27 to move upward, so that the third sealing ring 28 blocks the second water outlets 2111 to form a seal. When the upper water inlet pipe 11 extends into the lower water inlet channel and drives the first lower valve core 24 to move downwards to a certain position, the first lower valve core 24 abuts against the top of the collar 221 and drives the shaft body 22 to move downwards against the elastic force of the second elastic member 29, so as to drive the second lower valve core 27 and the third sealing ring 28 to move downwards to open the second water outlet 2111, as shown in fig. 8.

Therefore, when the lower water inlet assembly 2 is arranged on the base 5 of the electric heating thermos flask and the upper water inlet pipe 11 is separated from the lower water inlet pipe 21, under the elastic force of the second elastic piece 29, the movable shaft 22 is driven to move upwards so as to drive the second lower valve core 27 to move upwards, so that the third sealing ring 28 blocks the second water outlet 2111 to form a seal, water in a water pipe connected with the water outlet end of the water pump 9 is prevented from flowing back into the lower water inlet channel, the sealing effect is further improved, and the probability of water leakage of the lower water inlet assembly 2 is reduced.

When the upper coupler 3 and the lower coupler 4 are coupled, as shown in fig. 6-8, the upper water inlet pipe 11 of the upper water inlet assembly 1 extends into the lower water inlet channel of the lower water inlet assembly 2, and the operation process thereof can be described in the first embodiment and will not be repeated here.
