Description

Technical Field

[0001] This utility model relates to the technical field of water outlet locking structures, and in particular to a water outlet locking structure for an electrical appliance. Background Technology

[0002] The water outlet structure is used in some household appliances to connect to a water source and supply water to the appliance when in use. Existing appliances such as garment steamers only control the water outlet structure to dispense water through a one-way valve. After use, the water outlet structure cannot be completely shut off. In addition, it usually uses a straight water outlet line, which may result in residue or leakage after use. Since the existing water outlet structure does not have a locking and limiting function, it may also cause safety hazards when using some appliances. Utility Model Content

[0031] See Figures 1-10This utility model provides a water outlet locking structure for an electrical appliance, including a first locking mechanism and a sealing mechanism. The first locking mechanism includes a knob 1 and a pressure rod 2. The sealing mechanism includes a first swing rod 3 and a sealing plug 4. The first swing rod 3 is oscillatingly installed inside an external first housing 5. The sealing plug 4 is located at one end of the first swing rod 3. The first housing 5 is provided with a first elastic element 6 and a water outlet 7. The first elastic element 6 abuts against the lower end of the first swing rod 3, and the water outlet 7 is located at the lower end of the sealing plug 4. The first elastic element 6 pushes against one end of the first swing rod 3 so that the sealing plug 4 at the other end blocks the water outlet 7 downward to achieve a seal. The bottom of the knob 1 is provided with a guide part. The top end of the pressure rod 2 abuts against the guide part, and the bottom end abuts against the first swing rod 3 at the upper end of the first elastic element 6. Rotating the knob 1 can drive the pressure rod 2 to press down the first swing rod 3 through the guide part, so that the sealing plug 4 at the other end of the first swing rod 3 rises and disengages from the water outlet 7 to achieve water outlet. The water outlet 7 can only be opened by rotating the knob 1, thereby improving the sealing performance.

[0032] In some embodiments, such as Figures 2-6 As shown, a second locking mechanism is also provided on one side of the knob 1. The second locking mechanism includes a second rocker arm 8 and a rotating handle 9. The end of the second rocker arm 8 is provided with a locking part 10. The knob 1 is provided with a locking groove 11 corresponding to the locking part 10. The bottom of the rotating handle 9 is provided with an inclined guide surface 12. The drive column 13 at the top of the second rocker arm 8 abuts against the lower end of the guide surface 12. The upper end of the first housing 5 is fixed with a second housing 14. The rotating handle 9 is hinged to the second housing 14. The second housing 14 is provided with a mounting base 15 and a second hinge base 16 inside. The knob 1 is located above the mounting base 15 and passes through the top of the second housing 14. The pressure rod 2 passes through the mounting base 15. The second rocker arm 8 is hinged to the second... On the hinge seat 16, the second housing 14 is located at the bottom of the drive column 13 and a second elastic element 17 is also installed. The second elastic element 17 pushes the second rocker arm 8 so that the locking part 10 is placed in the locking groove 11. In the locked state, the rotary handle 9 is in the retracted state. After the rotary handle 9 is opened, the drive column 13 can be pressed down through the guide surface 12, so that the second rocker arm 8 is pressed down at one end of the second elastic element 17. At this time, the locking part 10 at the other end rises and disengages from the locking groove 11, so that the knob 1 is unlocked. The second locking mechanism has a double locking effect. The knob 1 must be unlocked first before the first locking mechanism can be opened by the knob 1. That is, the rotary handle 9 must be opened first when using the equipment, which further improves the sealing and safety.

[0033] In some embodiments, such as Figures 2-4 , Figure 7As shown, the guide section includes a rotationally symmetrically arranged guide step 18. The guide step 18 is inclined and one end is bent to form a horizontal buffer section 19. The end of the guide step 18 is provided with a first locking surface 20, and the end of the buffer section 19 is provided with a second locking surface 21. The top of the pressure rod 2 is symmetrically provided with a drive section 22. The drive section 22 abuts against the guide step 18. When the knob 1 is rotated, the drive section 22 moves along the guide step 18 to the first locking surface 20 or the second locking surface 21 and stops positioning. When the drive section 22 is located at the first locking surface 20, the first swing rod 3 is in a locked state, and when it moves to the second locking surface 21, the first swing rod 3 is in an unlocked state.

[0034] In some embodiments, such as Figure 2 , Figure 9 and Figure 10 As shown, a third elastic element 23 is fitted onto the pressure rod 2. The third elastic element 23 is installed in the mounting base 15 and is used to push the pressure rod 2 upward so that the drive part 22 always abuts against the guide step 18. A first hinge seat 24 is provided on the first housing 5. The first swing rod 3 is hinged to the first hinge seat 24. The first swing rod 3 is bent downward along the connection of the first hinge seat 24 to form a connecting part 25. The connecting part 25 is connected to the sealing plug 4. The top end of the first swing rod 3 is provided with a force groove 26. The bottom of the pressure rod 2 is placed in the force groove 26. A first positioning post 27 is provided on the first housing 5. The first elastic element 6 is fitted onto the first positioning post 27. A second positioning post 28 is provided inside the second housing 14. The second elastic element 17 is fitted onto the second positioning post 28. The first elastic element 6, the second elastic element 17 and the third elastic element 23 are all springs.

[0035] This utility model provides a water outlet locking structure for an electrical appliance. The sealing plug in the sealing mechanism can be adjusted to seal or unlock the water outlet through the knob in the first locking mechanism, thereby making the water outlet structure of the electrical appliance adjustable. The second locking mechanism can lock the sealing mechanism a second time by rotating the handle to lock the knob, further improving the sealing performance and preventing liquid leakage caused by accidental contact during or after use, thus improving safety.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
