Embodiment 1

[0060] In the scheme of embodiment one, such as Figure 5 to Figure 8 As shown, the inner wall of the vent pipe 5 is provided with a first step portion 501, and the inner diameter of the vent pipe 5 becomes smaller from the cup cover 3 to the bottom of the cup, that is, the inner diameter of the pipe above the first step portion 501 is larger than the first step portion 501 The inner diameter of the lower pipe, the ventilation switch device includes a first sealing plug 51 that can move along the axial direction of the ventilation pipe 5 to block the first step 501. When the filter cup is placed upright, the first sealing plug 51 is blocked under its own gravity. The first step part 501, the first sealing plug 51 is separated from the first step part 501 when the filter water cup is turned upside down, and the end of the vent tube 5 facing the cup cover 3 is provided with a first stop that restricts the first sealing plug 51 from coming out of the vent tube 5 Structure 502. W...

Embodiment 2

[0065] Please refer to Figure 9 and Figure 10 , in the second embodiment, the ventilation switch device includes a second sealing plug 52 and an elastic member 53 arranged inside the upper nozzle of the ventilation pipe 5, and the elastic member 53 acts on the second sealing plug 52 and when the filter cup is placed upright Drive the second sealing plug 52 to block the upper nozzle of the vent pipe 5, the cup cover 3 is provided with a movable rod 34 that can stretch into and withdraw from the vent pipe 5, and the movable rod 34 acts on the second sealing plug 52 when the filter water cup is inverted and Drive the second sealing plug 52 to open the upper nozzle of the vent pipe 5 .

[0066] Wherein, the movable rod 34 can be arranged on the cup cover 3 in a variety of ways, for example, a through hole is opened on the cup cover 3 to slide through the movable rod 34, or the movable rod 34 is connected to the cup cover 3 through a flexible connector, preferably ,Such as Fi...

Embodiment 3

[0071] Please refer to Figure 11 and Figure 12 , in the third embodiment, the ventilation switch device includes a hollow valve body 505 connected to the lower end nozzle of the ventilation pipe 5, the upper end opening of the hollow valve body 505 communicates with the lower end nozzle of the ventilation pipe 5 and the lower end opening of the hollow valve body 505 Arranged toward the bottom of the cup, the inner cavity of the hollow valve body 505 contains a third sealing plug 54, when the filter water cup is upright, the third sealing plug 54 blocks the lower end opening of the hollow valve body 505 under its own gravity, and when the filter water cup is inverted When the third sealing plug 54 breaks away from the lower end opening of the hollow valve body 505, the hollow valve body 505 is internally provided with a support portion 506 that supports the third sealing plug 54 when the filter water cup is inverted, and the support portion is provided with a communication ve...

Abstract

The invention discloses a filtering water cup which comprises a cup body, a filter element, a water storage shell and a cup lid. The lower end of the water storage shell and the cup body are connected in a detachable and sealed mode, and the upper end of the water storage shell and the cup lid are connected in a detachable and sealed mode. The inner wall of the water storage shell and the periphery of the filter element are in sealed connection. A water storage cavity is formed among the filter element, the cup lid and the water storage shell. A vent pipe communicated with the water storage cavity and an inner cavity of the cup body is arranged on the filter element in a penetrating mode. A ventilation switching device is arranged inside the vent pipe. The ventilation switching device blocks the vent pipe when the filtering water cup is installed forward, and is communicated with the vent pipe when the filtering water cup is installed reversely. When the water cup contains water, the water storage shell and the cup lid are taken down, water is directly added into the cup body, and the water storage shell and the cup lid are fixed to a cup opening; during filtering, the water cup is installed reversely, gas inside the water storage cavity enters the cup body through the vent pipe, and water inside the cup body flows into the water storage cavity through the filter element, so that filtering is achieved. According to the filtering water cup, the water containing operation is quite convenient, the filtering mode is simple and easy to implement, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of filter water cups, in particular to a filter water cup. Background technique [0002] The filter water cup utilizes the filter element to purify the drinking water, thereby providing consumers with clean drinking water that is easy to carry with them, which is beneficial to human health. At present, the existing filter cups on the market can be roughly divided into the following types according to their different filtering methods: [0003] 1) Gravity filtration when filling water, the filter element module is installed under the cup mouth, a water storage area is formed between the filter element and the cup mouth, and there is a ventilation pipe in the middle of the filter element that connects the water storage area and the inner cavity of the cup under the filter element. Pour water into the water storage area at the same time, and then use the gravity of the water to pass through the filter element ...
