Description

Anti-corrosion components for liquid detergent dispensers

technical field

The invention relates to a liquid detergent dispensing device for washing machines, in particular to a liquid detergent dispensing device with the function of anti-corrosion and sealing of interface parts.

Background technique

In the prior art, the CN 10631975 B patent discloses a detergent storage and delivery device with a detection function for a drum washing machine. There is a one-way valve at the through hole of the recess of the container, the detergent container is pushed into the washing machine body, the upper recess is sleeved into the conversion joint, the convex top of the conversion joint opens the one-way valve, and the liquid detergent in the detergent container Input the washing machine body through the adapter. In the practical application of the device, in addition to detergents, various preparations such as softeners and bleaches can also be put in. The problem that occurs after the device is used is that the corresponding parts of the seal and leak-proof are corroded. The outer wall of the conversion joint of the device is provided with a rubber sealing ring, which is contacted and sealed with the notch of the detergent washing machine body to prevent leakage when the detergent is delivered. When the detergent is input into the washing machine body and the washing machine body is filled with detergent, the detergent will fill the adapter and overflow from the mouth. The spilled detergent will corrode the rubber sealing ring on the outer wall of the adapter. Damaged and the seal is lost, the detergent will leak out.

SUMMARY OF THE INVENTION

The present invention aims to solve the problem that the relevant sealing parts of the detergent dispensing device are easily corroded and cause detergent to overflow in the prior art. Therefore, the anti-corrosion component of the liquid detergent dispensing device of the present invention is provided, and the anti-corrosion component can prevent the detergent dispensing device. Corroded seals to avoid detergent spillage.

In order to solve the above-mentioned problems, the technical solution adopted in the present invention is that a removable detergent container is arranged in the washing machine body, a one-way valve is provided at the through hole corresponding to the recess of the detergent container, and a wall of the washing machine body is provided. A liquid inlet conversion joint is communicated with each other, the conversion joint corresponds to the notch, the convex top of the conversion joint corresponds to the one-way valve, and it is characterized in that the notch of the detergent container is connected with a downward extension When the notch is sleeved on the adapter, the sleeve is sleeved on the adapter.

An optional way is that a plastic protection ring is provided near the top of the outer wall of the conversion joint.

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Detailed ways

Example 1

The anti-corrosion component of the liquid detergent dispensing device, the washing machine body 5 is provided with a removable detergent container 1, and the through hole 1-11 corresponding to the recess 1-1 of the detergent container 1 is provided with a one-way valve 2, A wall of the washing machine body 5 is communicated with a liquid inlet adapter 4, the adapter 4 corresponds to the recess 1-1, the convex top 4-1 of the adapter corresponds to the one-way valve 2, and the detergent container The notch 1-1 of 1 is connected with a downwardly extending sleeve 1-2 coaxial with the notch. When the notch 1-1 is sleeved on the adapter 4, the sleeve 1-2 is sleeved on the adapter 4. , see Figure 4.

Push the detergent container 1 into the washing machine body 5, the notch 1-1 of the detergent container 1 is then sleeved into the adapter 4, and the outer wall of the adapter 4 is embedded with a V-shaped rubber sealing ring 3, and the V-shaped rubber sealing ring 3 seals contact with the inner wall of the recess 1-1, the inner sleeve of the sleeve 1-2 is sleeved on the adapter 4, the convex top 4-1 of the adapter 4 pushes the one-way valve 22, and the liquid detergent in the detergent container 1 It is input into the washing machine body 5, and then output from the washing machine body 5. The detergent container 1 can also be pulled out from the washing machine body 5 . After the liquid detergent is input into the washing machine body 5, the adapter 4 is filled with liquid detergent. In the past, a small amount of the liquid detergent would overflow from the port of the adapter 4. Referring to Figure 1, the liquid detergent is filled in the notch 1. -1, the V-shaped rubber sealing ring 3 of the adapter will be corroded, and the sealing effect will be lost, and the detergent will leak from the adapter. In the present invention, because the recess 1-1 of the detergent container 1 is provided with a sleeve 1-2, when the recess 1-1 is sleeved with the conversion joint 4, the sleeve 1-2 is sleeved inside the conversion joint 4, and the conversion joint 4 When the detergent is filled, the gap 6 between the adapter 4 and the sleeve 1-2 and the air in the notch 1-1 are liquid-sealed, see Figure 4, the air will not flow to the lumen 1-21 of the sleeve , so the air is compressed, the compressed air prevents the liquid detergent from entering the notch 1-1, so the V-shaped rubber sealing ring 3 on the adapter 4 will not be corroded, the sealing is guaranteed, and the liquid detergent will not leak .

The invention has the characteristics of simple structure, good effect and low cost.

Example 2

For the anti-corrosion component of the liquid detergent dispensing device in this example, see FIG. 5 , a plastic protection ring 7 is provided on the outer wall of the adapter 4 near the top. This is that once a small amount of liquid detergent enters the notch 1-1, the plastic protection ring 7 can act as an avant-garde protection, protect the V-shaped rubber sealing ring 3 from corrosion, and ensure the sealing.

Claims (2)
