Abstract

An anticorrosion component of a liquid detergent dispensing apparatus. A retrievable detergent container (1) is arranged within a washing machine body (5). A check valve (2) is provided at a through hole (1-11) corresponding to where a recessed opening (1-1) of the detergent container (1) is located. A wall part of the washing machine body (5) is in communication with a liquid inlet adapter (4). The adapter (4) corresponds to the recessed opening (1-1). A protruding top (4-1) of the adapter (4) corresponds to the check valve (2). A sleeve pipe (1-2) extending downwards is connected to where the recessed opening (1-1) of the detergent container (1) is located. When the recessed opening (1-1) is sleeved on the adapter (4), the sleeve pipe (1-2) is sleeved by the adapter (4). This is applicable in the liquid detergent dispensing apparatus, prevents a sealing element from being corroded, and ensures sealing.

Description

Antiseptic component of liquid detergent dispensing device

Technical field

The invention relates to a liquid detergent dispensing device for a washing machine, in particular to a liquid detergent dispensing device with an anticorrosive and sealing function for interface parts.

Background technique

The CN 10631975 patent in the prior art discloses a detergent storage and dispensing device with a detection function for a drum washing machine. A box (which may be a washing machine body) of the device is provided with a conversion connector for inputting liquid detergent. The detergent The through hole of the recess of the container is provided with a one-way valve. The detergent container is pushed into the washing machine body, and 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 Enter the washing machine body through the adapter. In addition to the detergent, various preparations such as softener and bleach can be added to the device in practical applications. A problem that occurs after the device is used is that the corresponding parts of the leakproof seal are corroded. The outer wall of the conversion joint of the device is provided with a rubber seal ring, which is in contact with the recess of the washing machine body and is sealed to prevent leakage during the delivery of the detergent. When the detergent is input into the washing machine body and the detergent is filled in the washing machine body, the detergent will fill the adapter and leak out from the mouth. The spilled detergent will corrode the rubber seal on the outer wall of the adapter. If the seal is damaged, the detergent will leak out.

Summary of the Invention

The present invention is to solve the problem that the related sealing parts of the detergent dispensing device in the prior art are easily corroded and the detergent overflows. Therefore, the anticorrosive component of the liquid detergent dispensing device of the present invention is provided. The relevant seals are eroded to prevent detergent leakage.

In order to solve the above problem, the technical solution adopted by the present invention is that a removable detergent container is arranged in the washing machine body, a check valve is provided at a through hole corresponding to the recess of the detergent container, and one wall of the washing machine body is provided. A liquid inlet conversion joint is connected to the part, and the conversion joint corresponds to the recess. The convex top of the conversion joint corresponds to the check valve. The feature is that the recess of the detergent container is connected with a downward extension. When the notch is sheathed on the conversion joint, the sleeve is sleeved on the conversion joint.

Alternatively, a plastic protection ring is provided near the top of the outer wall of the conversion joint.

The invention is further described below with reference to the drawings and specific embodiments.

detailed description

Example one

The anticorrosive component of the liquid detergent dispensing device. A removable detergent container 1 is disposed in the washing machine body 5, and a one-way valve 2 is provided at the through hole 1-11 corresponding to the recess 1-1 of the detergent container 1, A liquid inlet adapter 4 is connected to a wall portion of the washing machine body 5, and the adapter 4 corresponds to the notch 1-1. The convex top 4-1 of the adapter corresponds to the check valve 2. The detergent container The notch 1-1 of 1 is connected with a sleeve 1-2 which is coaxial with the notch and extends downward. When the notch 1-1 is sheathed on the adapter 4, the sleeve 1-2 is sleeved on the adapter 4 See Figure 4.

The detergent container 1 is pushed into the washing machine body 5, and the recess 1-1 of the detergent container 1 is sleeved into the adapter 4. The outer wall of the adapter 4 is fitted with a V-shaped rubber seal 3, which is sealed by the V-shaped rubber seal 3 It touches the inner wall of the notch 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 opens the check valve 22, and the liquid detergent in the detergent container 1 It is then input to the washing machine body 5 and then output from the washing machine body 5. The detergent container 1 may be withdrawn 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 overflowed from the mouth of the adapter 4. See FIG. 1, the liquid detergent is filled in the recess 1 -1, the V-shaped rubber seal 3 of the adapter is corroded and the sealing effect is lost, and detergent will leak from the adapter. In the present invention, the sleeve 1-2 is provided at the recess 1-1 of the detergent container 1. 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 filling with detergent, the air 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, this air will not flow to the lumen 1-21 of the sleeve Therefore, the air is compressed, and the compressed air prevents the liquid detergent from entering the notch 1-1, so the V-shaped rubber seal 3 on the adapter 4 will not be corroded, the seal is guaranteed, and the liquid detergent will not leak. .

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

Example two

The anticorrosive component of the liquid detergent dispenser of this example is shown in FIG. 5. A plastic protection ring 7 is provided near the top of the outer wall of the conversion joint 4. This is because once a small amount of liquid detergent enters the notch 1-1, the plastic protection ring 7 can provide avant-garde protection to protect the V-shaped rubber seal 3 from corrosion and ensure sealing.
