Description

Technical Field

[0001] The utility model relates to the technical field of household products, in particular to a pressing device. Background Art

[0002] Since washing machines with automatic detergent addition function are relatively expensive, most washing machines currently sold on the market do not have the function of automatically adding detergent. The washing machines currently on the market are mainly divided into two types: pulsator type and drum type. When pouring detergent into a pulsator type washing machine, the detergent bottle is generally lifted directly and poured into the washing tub; when pouring detergent into a drum type washing machine, the detergent is generally poured into the detergent tank, and then flows into the drum through the detergent tank; in addition, in order to master the amount of detergent to be poured, the detergent can also be poured into the measuring cup cover to measure, and then poured into the washing machine. The detergent sold on the market is generally in two ways: bagged and bottled. Common detergents are generally 0.5 kg, 1 kg, 2 kg, 2.5 kg, 3 kg, etc. This way of pouring detergent is difficult to control the amount of detergent poured when using a heavier detergent bottle of 1 kg or more, which can easily cause too much detergent to be poured; in addition, the newly opened bottled detergent is full of detergent and the liquid level is close to the bottle mouth, which is more likely to cause too much detergent to be poured, resulting in waste. When using a measuring cup lid, it is also easy to pour too much, and the laundry detergent can easily overflow and get on your hands or drip onto the floor, which also causes waste.

[0003] A Chinese patent with a publication (announcement) number of CN204803618U discloses a washing machine with a device for adding laundry detergent, comprising a washing machine body, a laundry detergent adding device installed on the upper part of the washing machine body through a support rod, the laundry detergent adding device comprising a laundry detergent bottle and an outer shell, the laundry detergent bottle is arranged in the outer shell, the outer shell is composed of a front shell and a rear shell, the bottom of the front shell is connected to the bottom of the rear shell by a rotating shaft, a liquid injection port is opened on the top of the laundry detergent bottle, a press-type liquid pump is installed at the bottom of the laundry detergent bottle, a liquid outlet hole is opened at the bottom of the front shell, a liquid outlet pipe on the press-type liquid pump extends from the liquid outlet hole, and the front shell A pressing plate is installed on the upper shell through a rotating shaft, and the pressing plate is pressed on the pressing rod on the pressing liquid pump. A fixing hole is opened on the top of the front shell, and an elastic protrusion for being inserted into the fixing hole is arranged on the top of the rear shell. Although the above-mentioned washing machine with a laundry detergent delivery device solves the problem of needing to lift a heavy laundry detergent bottle to pour the laundry detergent into the washing machine every time, a large installation space needs to be reserved above the washing machine, and the device is inconvenient to install, which affects the operation and use of the washing machine. At the same time, it is not suitable for a drum washing machine, and when the laundry detergent is poured into the above-mentioned device, there will also be the problem that the aforementioned laundry detergent is easy to get on the hands or drip on the floor, causing waste.
