Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a steam pipe component with adjustable rotation force and a coffee machine. Background Art

[0002] Pressure coffee machines are usually equipped with a steam pipe device for producing steam and hot water. Currently, the steam pipe devices on the market are usually composed of a universal joint and a gland; the steam pipe device can rotate, but too much rotation may cause internal pipe breakage or accidental injury to customers, so the steam pipe device is equipped with a limit plate, and its general rotation angle is 45 degrees.

[0003] For example, a Chinese utility model patent with the authorization announcement number CN219353619U discloses a movable device for a steam pipe, which is used on a coffee machine. The movable device includes a fixed seat, which is fixed on the coffee machine; a pipe seat, which is arranged on the fixed seat and connected to the steam pipe, and when the steam pipe rotates, it can drive the pipe seat to rotate synchronously relative to the fixed seat, and a limiting bone is provided on the pipe seat; two limiting parts, which are respectively arranged on the fixed seat and are arranged at intervals along the rotation direction of the pipe seat, and when the pipe seat rotates in the clockwise direction or the counterclockwise direction, the limiting bone can abut against one of the limiting parts to limit the pipe seat from continuing to rotate. This prior art drives the pipe seat to rotate synchronously on the fixed seat while the steam pipe rotates, and limits the rotation of the pipe seat by the two limiting parts on the fixed seat, which can prevent the connection pipe connected to the steam pipe on the coffee machine from being bent after the steam pipe rotates more than 360 degrees, thereby avoiding functional and safety problems caused by the coffee machine not producing steam. However, the rotation force between the steam pipe and the fixed seat in the prior art is fixed and cannot be adjusted. When customers need different rotation forces, no quick and effective solution can be obtained, and customer needs cannot be met.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0005] In view of the problems in the prior art, the utility model provides a steam pipe assembly with adjustable rotation force. By tightening or loosening the position of the nut relative to the fixed seat, the compression degree of the elastic component is controlled, and then the extrusion force of the elastic component relative to the bracket is adjusted, so that the bracket and the steam pipe are tightly or loosely matched, thereby adjusting the rotation force of the steam pipe. When customers need different rotation forces, the utility model can quickly and effectively meet customer needs. It has a simple structure and is easy to assemble.

[0006] In order to achieve the above purpose, the technical solution applied by the utility model is as follows:

In this way, by tightening or loosening the position of the nut relative to the fixing seat, the compression degree of the elastic component is controlled, and then the extrusion force of the elastic component relative to the bracket is adjusted, so that the bracket and the steam pipe are tightly or loosely matched, so as to adjust the rotation force of the steam pipe; when customers need different hand-feel rotation forces, the customer needs can be met quickly and effectively; it has a simple structure and is easy to assemble.

In practical applications, the limiting hemispherical head is arranged on the upper side of the first end of the steam pipe; and the clamping block is arranged on the upper side in the fixing seat.

[0010] According to the above scheme, a limiting plane is provided on the steam pipe, and a limiting bone is provided in the fixed seat, and the limiting plane and the limiting bone are correspondingly limited.

In practical applications, the limiting plane is set on the lower side of the first end of the steam pipe; the limiting bone is set on the lower side in the fixed seat.

[0011] According to the above solution, a steam through hole is provided in the bracket, and one end of the steam through hole near the steam pipe is a trumpet-shaped opening. In this way, the trumpet-shaped opening can be interference-fitted with the first end of the steam pipe to prevent steam leakage.

This arrangement makes it easy to load and unload.

[0015] According to the above solution, a bending portion is provided between the first end and the second end of the steam pipe. With this arrangement, the first end of the steam pipe can be rotated relative to the fixing seat by moving the second end of the steam pipe, which makes the steam pipe rotation more convenient; and the steam nozzle of the second end of the steam pipe can be opened downward and not facing the user, which makes it safer to use.
