Description

Technical Field

[0001] The utility model relates to a quick-sealing water-passing coupler and a tea bar machine. Background Art

[0002] In the prior art, couplers are widely used. For example, electric kettles, electric hot pots, electric coffee pots, etc., which are closely related to our lives, are usually electrically connected by setting couplers. For example, a tea bar machine with a heating function is usually provided with a lower connector that is coupled with an upper connector set on the electric kettle to boil water. In order to improve the convenience of using appliances such as kettles, a water supply device is arranged on the coupler to guide liquid into the kettle body. The water supply device includes an upper water inlet assembly arranged in the upper connector and a lower water inlet assembly arranged in the lower connector. As the upper connector is plugged in and disconnected from the lower connector, the upper water inlet assembly and the lower water inlet assembly are connected and disconnected. In the existing lower water inlet coupler structure, the upper valve core and the lower valve core are mainly moved by spring reset to realize the connection and disconnection of the upper water inlet sleeve and the lower water inlet sleeve. The elastic force and force direction of the two springs are difficult to control and are greatly affected by the water flow force. The spring is prone to twisting and bending, resulting in elastic force failure, which will not only cause the seal between the valve core and the sleeve to be loose and cause water leakage, but also affect the normal water inlet of the electric kettle and reduce the user experience.

The upper part of the upper sealing column 5 is of a two-stage stepped shaft structure and the connection is transitioned through an inclined surface 53. An upper return spring 52 is arranged in cooperation with the upper sealing column 5. A guide sleeve 51 is integrally arranged in the middle of the upper sealing column 5 and forms a sliding fit with the upper water inlet sleeve 6. An upper return spring 52 is arranged above the guide sleeve 51 and on the upper sealing column 5. The upper return spring 52 forces the upper sealing ring 55 to abut against the top of the upper water inlet sleeve 6 to close the water outlet 61. An upper water flow channel 56 is axially machined on the outer peripheral surface of the upper sealing column 5 below the circular sealing groove I 54 and penetrates to the bottom of the upper sealing column 5 (see Figure 4 );

[0026] The coupler base includes a lower water inlet sleeve 3 arranged on the upper part of the placement platform 8. The outer diameter of the upper part of the lower water inlet sleeve 3 matches the inner diameter of the upper water inlet sleeve 6. Two groups of sealing rings I 36 are embedded on the outer peripheral surface of the upper part of the lower water inlet sleeve 3 along the axial direction of the lower water inlet sleeve 3. The lower part of the lower water inlet sleeve 3 passes through the placement platform 8 and is connected and positioned with a lower positioning sleeve 2. The middle part of the inner cavity of the lower water inlet sleeve 3 contracts to form a diversion port 32. The diversion port 32 divides the inner cavity of the lower water inlet sleeve 3 into a lower chamber 31 and an upper chamber 33. A lower sealing column 4 is slidably installed in the lower water inlet sleeve 3. The lower sealing column 4 is of a conical structure with a gradually decreasing diameter from top to bottom. The upper part of the lower sealing column 4 is placed in the upper chamber 33 and a lower return spring 42 is arranged. The upper end of the lower sealing column 4 radially extends to form a circular convex edge I 41. A lower return spring 42 is arranged below the circular convex edge I 41 and on the lower sealing column 4. The elastic force of the upper return spring 52 is greater than that of the lower return spring 42. The lower part of the lower sealing column 4 is placed in the lower chamber 31 and the end is machined with a circular sealing groove 43. A lower sealing ring 44 is installed in the circular sealing groove 43. The lower return spring 42 forces the lower sealing ring 44 to abut against the top wall of the lower chamber 31 to close the diversion port 32. An inlet connection sleeve 1 is fixedly arranged in the lower positioning sleeve 2 and is communicated with the lower chamber 31. A lower water flow channel 45 is axially machined on the outer peripheral surface of the lower sealing column 4 above the circular sealing groove 43 to the top of the lower sealing column 4 (see Figure 3) The upper water flow channels 56 are evenly arranged along the circumferential direction of the upper sealing column 5, and the lower water flow channels 45 are evenly arranged along the circumferential direction of the lower sealing column 4.

The lower water inlet sleeve extends into the upper water inlet sleeve, and at the same time, the lower part of the upper sealing column extends into the lower water inlet sleeve. Since the elastic force of the upper return spring is greater than that of the lower return spring, the upper sealing column presses down the lower sealing column until the lower part of the guide sleeve outside the upper sealing column abuts against the lower water inlet sleeve. The lower sealing column slides down relative to the lower water inlet sleeve, and the lower sealing ring disengages from the diversion port, and the diversion port opens. The lower water inlet sleeve jacks up the guide sleeve and the upper sealing column until the circular convex edge in the middle of the lower water inlet sleeve fits into the groove at the lower opening of the upper water inlet sleeve, and the upper sealing ring disengages from the water outlet, and the water outlet opens; inside the coupler, the water inlet connecting sleeve - the lower chamber in the lower water inlet sleeve, the diversion port, the upper chamber - the lower diversion channel on the lower sealing column - the upper diversion channel on the upper sealing column - the water outlet at the upper part of the upper water inlet sleeve are sequentially conducted. The lower end of the water inlet connecting sleeve is connected to the water inlet pipe. The water flow enters the lower chamber along the water inlet connecting sleeve, then is dispersed on the lower diversion channel on the lower sealing column and enters the water receiving container through the water outlet along the upper diversion channel on the upper sealing column; after receiving water, the water receiving container is removed, the lower water inlet sleeve withdraws from the upper water inlet sleeve, and the upper sealing column and the lower sealing column are reset by the upper return spring and the lower return spring respectively, and the diversion port and the water outlet are automatically closed respectively.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
