Description

Filter connector improvement

This creation is about a "filter filter joint improvement", especially a filter filter joint structure that has a backstop effect.

According to the conventional filter connector of the water filter, as shown in the sixth and seventh figures, the filter connector (50) is mainly provided with a water inlet (51) at two opposite sides and a bottom end, a water outlet (52) and a screwing groove (53), wherein the opening groove (53) is separated by a ring wall (54) to form a water inlet flow channel (55) and a water outlet flow channel (56). And the inlet and outlet water passages (55) (56) are respectively connected to the inlet and outlet ports (51) (52); in use, the filter core joints are connected by a screwing groove (53) ( 50) Rotate the card at the top of the filter (60) (as shown in Figure 8), and connect the water source with the water inlet (51). The water outlet (52) is connected to the water equipment. When the water source uses the water inlet channel (55) The turning point is sent to the filter core (60), and the water source can be filtered into the filtered water by the filter core (60), and then discharged from the water outlet passage (56) through the water outlet (52). The outflow allows the user to complete the water withdrawal of the filtered water through the opening and closing of the water device switch.

However, the conventional structure as described above still has the following problems in practical applications: the water outlet (52) and the water outlet channel (56) of the filter connector (50) can only provide filtered filtration. Clean water The outflow, without the reverse function, causes the outflowing filtered water to flow back to the filter core (60), which causes the water quality to be unguaranteed.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional filter joints is a goal that the relevant industry needs to work hard to develop. This creator has the idea of thinking and creation, and has many years of experience. The design, the multi-party discussion and trial sample test, and many corrections and improvements, is the launch of this creation.

The water outlet and the water outlet channel of the conventional filter connector can only provide the filtered filtered water outflow without the reverse function, which is the technical problem to be solved.

The present invention provides a filter connector improvement of a water filter, comprising: a filter core connector, a check valve and a pipe joint set, wherein the filter core connector has a water inlet and a water outlet, and the bottom end is upward. a recessed groove is defined in the recess, and a water inlet flow passage is connected to the end of the water inlet, and a horizontal water outlet passage is connected to the end of the water outlet. The inlet flow passage and the outlet flow passage are provided with a ring wall connected to the bottom surface of the groove of the screwing groove, and the partition of the ring wall allows the inlet flow passage and the outlet passage to be sufficiently separated. The water outlet passage penetrates through the ring wall, and the filtered water can be smoothly transported to the water outlet direction, and the vehicle is stopped. The valve has a bottom ring portion and a water pipe connected to a center of one end of the bottom ring portion, the water pipe is formed by two opposite first faces and two opposite second faces, and the first faces of the two are The end of the bottom ring portion is inclined to the other end, so that the water pipe can be gradually flattened due to the close contact of the two first faces at the end, and the inner hole of the bottom ring portion And connecting to the inner tube portion of the water pipe as a water flow passage, and the water flow passage is formed on a side different from the bottom ring portion to fit the flat shape of the water pipe to form a water stop portion, and the The valve is disposed in the water outlet channel with the bottom ring portion facing the water outlet, and is used to remove the check valve by using the combination of the pipe joint group and the water outlet after being placed. The time limit is limited, and the check valve is made of a soft material such as rubber or silicone, so that the check valve can have the ability to be elastically deformed under pressure, thereby obtaining a filter of the water filter. Connector improver.

The present invention provides an improvement of the filter joint of the water filter, which can prevent the water filter from being reversed during use by the installation of the check valve, which can ensure the quality of water.
