Description

Technical Field

[0001] The utility model belongs to the technical field of coffee machine water pumps, in particular to a coffee machine water pump. Background Art

[0002] Coffee machine water pumps are typically electric pumps, driven by a motor to extract and deliver water. The working principle of a water pump can be simply understood as the motor driving the impeller inside the pump body to rotate, thereby generating a certain negative pressure, drawing water from the water tank and delivering it through pipes to the required location.

[0003] Existing water pumps used in small appliances such as coffee machines have limited installation locations and the angle of the water outlet or water inlet of the water pump cannot be adjusted. When installing the pipeline, there are different direction requirements. Therefore, some connectors need to be added for conversion. This not only makes the parts in the machine redundant, but also increases some safety hazards. Utility Model Content

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] Example

[0018] like Figure 1 and Figure 2 As shown, the coffee machine water pump includes a water pump body 1, which is provided with a water inlet joint 11 and a water outlet joint 13. The water outlet joint 13 is rotatably connected to a rotary joint 2 at one end away from the water pump body 1. An adjustment mechanism 3 is installed on the outer wall of the rotary joint 2. A positioning slider 14 is fixedly connected to the outer wall of the water outlet joint 13. The positioning slider 14 is plugged into and matched with the adjustment mechanism 3 to limit the rotation of the rotary joint 2.

[0019] It should be noted that an anti-seepage portion 12 is provided on the outer wall of the end of the water inlet joint 11 away from the water pump body 1, and an anti-seepage portion 23 is provided on the outer wall of the end of the rotary joint 2 away from the water pump body 1. The anti-seepage portion 12 and the anti-seepage portion 23 are both conical, and the side close to the end is lower than the side away from the end, so that the hose is not prone to leakage when connected to the water inlet joint 11 and the rotary joint 2.

[0020] Specifically, by pulling the adjustment mechanism 3 to disengage it from the positioning slider 14, the rotation angle of the rotary joint 2 can be adjusted, so that there is no need to use connectors for connection when installing the pipeline, which not only reduces the use of parts but also reduces the failure rate.

[0021] like Figure 1 and Figure 2 As shown, the adjustment mechanism 3 includes an angle adjustment sleeve 31, which is movably mounted on the outer ring of the rotary joint 2, and a plurality of positioning grooves 32 are provided on the inner wall of the angle adjustment sleeve 31. A plurality of guide sliders 21 are fixedly connected to the outer wall of the rotary joint 2, and the guide slider 21 and the positioning slider 14 both slide in cooperation with the positioning grooves 32.

[0022] Specifically, the number of positioning grooves 32 is the same as that of the guide slider 21. Through the sliding cooperation between the positioning grooves 32 and the guide slider 21, the angle adjustment sleeve 31 can only move on the outer ring of the rotating joint 2 and cannot rotate. When the positioning grooves 32 opened on the inner wall of the angle adjustment sleeve 31 are completely disengaged from the positioning slider 14 fixed on the outer wall of the water outlet joint 13, the rotating joint 2 can be rotated and adjusted.

[0023] like Figure 2 As shown, the outer ring fixed sleeve of the angle adjustment sleeve 31 is provided with a push-pull plate 33 , the outer ring fixed sleeve of the rotary joint 2 is provided with a baffle 22 , and an elastic member 34 is fixedly connected between the baffle 22 and the push-pull plate 33 .

[0024] It should be noted that the elastic member 34 is a spring. Through the force of the elastic member 34, the push-pull plate 33 will push the angle adjustment sleeve 31 away from the baffle 22 without any external force, so that the positioning slider 14 remains plugged into the positioning groove 32, limiting the rotation of the rotating joint 2.

[0025] like Figure 2 As shown, the outer wall of the angle adjustment sleeve 31 is provided with a plurality of marking lines, and the marking lines correspond to the positioning grooves 32 one by one.

[0026] Specifically, after the rotary joint 2 is rotated and adjusted, one of the marking lines is aligned with any one of the positioning sliders 14 , and then the positioning groove 32 of the angle adjustment sleeve 31 can be plugged into the positioning slider 14 .

[0027] like Figure 2 As shown, a groove 1 is provided on the outer wall of the water outlet joint 13, a groove 2 is provided on the inner wall of the rotary joint 2, and a sealing ring 4 is provided between the groove 1 and the groove 2.

[0028] It should be noted that the provision of the sealing ring 4 can prevent liquid from leaking from the rotary joint 2 and the water outlet joint 13 .

[0029] Working principle: First, pull the push-pull plate 33 to make it close to the baffle 22. Through the sliding cooperation between the positioning groove 32 and the guide slider 21, the angle adjustment sleeve 31 can only move on the outer ring of the rotary joint 2 and cannot rotate. When the positioning groove 32 opened on the inner wall of the angle adjustment sleeve 31 is completely disengaged from the positioning slider 14 fixed on the outer wall of the water outlet joint 13, the rotary joint 2 can be rotated and adjusted. After the rotary joint 2 is rotated and adjusted, align one of the marking lines with any one of the positioning sliders 14, and then release the push-pull plate 33. Through the elastic member 34, the angle adjustment sleeve 31 can be rotated and adjusted. The force causes the push-pull plate 33 to push the angle adjustment sleeve 31 away from the baffle 22 without any external force, so that the positioning slider 14 remains plugged into the positioning groove 32, limiting the rotation of the rotary joint 2, thereby completing the angle adjustment of the rotary joint 2, so that there is no need to use connectors for transfer when installing the pipeline, while reducing the use of parts and reducing the failure rate. At the same time, the anti-seepage part 12 and the anti-seepage part 2 23 are both conical, and the side close to the end is lower than the side away from the end, so that the hose is not prone to leakage when connected to the water inlet joint 11 and the rotary joint 2.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
