Please refer to Figure 1, which is a schematic diagram of the structure of the first embodiment of the water purification equipment of the present invention, which includes: a water supply device 1, a water outlet device 2 and a filter device 3, wherein the filter device 3 is connected to the water supply device 1 and the water outlet device 2.

The water supply device 1 is used to provide raw water, and the water outlet device 2 is used to provide pure water. In this embodiment, the water outlet device 2 is a faucet.

Please refer to Figures 2 and 3. The filter device 3 includes a cylinder 31, a filter element 32, a telescopic hose 33 and a cover 34. The cylinder 31 has a accommodating space 35 inside. The cylinder 35 is divided into a first subspace 35a and a second subspace 35b by a connecting seat 36. In this embodiment, the first subspace 35a is used to accommodate the filter element 32, and the second subspace 35b is used to accommodate the telescopic hose 33. The connecting seat 36 has a first connecting port 361 and a second connecting port 362 that connect the first subspace 35a and the second subspace 35b.

The cylinder 31 is provided with a first water outlet H1 and a water inlet H2 connected to the first subspace 35a, and a second water outlet H3 connected to the second subspace 35b via the second connecting port 362. In this embodiment, the first water outlet H1 and the second water outlet H3 are connected to the water outlet device 2 via a first pipe p1 and a second pipe p2 respectively, and the water inlet H2 is connected to the water supply device 1 via a third pipe p3.

The filter element 32 is disposed in the first subspace 35a and has a water outlet 321, which extends through the first communication port 361 and blocks the first communication port 361. In this embodiment, the filter element 32 is a filter core having a plurality of filter materials, which is used to filter the raw water from the water supply device 1 to produce pure water. The plurality of filter materials may include maltstone, cationic resin, activated carbon and far infrared raw materials to filter the raw water to produce pure water with better taste and different functional effects.

The telescopic hose 33 is disposed in the second sub-space 35b and fixed above the connecting seat 36, whereby the telescopic hose 33 and the connecting seat 36 jointly define a closed sub-space 35c in the second sub-space 35b that is connected to the second water outlet 38 for pre-storing some pure water.

The cover 34 is provided with an elastic element 37 inside. In this embodiment, the elastic element 37 is a compression spring. The cover 34 is sleeved on the cylinder 31, and the elastic element 37 extends into the second sub-space 35b and abuts against the top surface of the telescopic hose 33.

Specifically, the outer wall of one end of the cylinder 31 closer to the second sub-space 35b is provided with an external thread, the inner wall of the cover 34 is provided with an internal thread corresponding to the external thread, and the cover 34 is screwed to the end of the cylinder 31.

Preferably, the water purification device of the present invention may also have a control valve 4, which is arranged in the second pipeline p2, for opening or closing the connection between the closed sub-space 35c and the water outlet device 2. In this embodiment, the control valve 4 is an electromagnetic valve. In detail, the control valve 4 is used to prevent the pure water in the closed sub-space 35c from flowing directly out of the water outlet device 2.

In this embodiment, when the water purification equipment is in use, the raw water provided by the water supply device 1 flows into the first sub-space 35a from the water inlet H2 through the third pipeline p3, and the filter element 32 filters the raw water to form pure water, a part of which flows into the closed sub-space 35c through the water outlet 321, so that the telescopic hose 33 is stretched from the compressed state, thereby compressing the elastic element 37, until the pure water can no longer flow into the closed sub-space 35c; the remaining part of the pure water remains in the first sub-space 35a.

When the diameter and length of the first pipe p1 and the second pipe p2 are equal, when the user controls the water outlet device 2 to open, the pure water remaining in the first sub-space 35a flows to the water outlet device 2 through the first water outlet H1; at the same time, the control valve 4 changes from the closed state to the open state, so that the water in the closed sub-space The pure water in 35c flows along the second water outlet H3 to the water outlet device 2, and with the assistance of the force generated by the elastic element 37 changing from a compressed state to an uncompressed state, the telescopic hose 33 is further compressed, so that the pure water in the closed sub-space 35c reaches the water outlet device 2 before the pure water in the first sub-space 35a. In this way, after the user controls the water outlet device 2 to open, the pure water will flow directly from the water outlet device 2 in a very short time or even without delay.

Please refer to Figures 4 and 5, which are respectively a schematic diagram of the structure of the second embodiment of the water purification equipment of the present invention and a cross-sectional view of the filter device of the second embodiment. In this embodiment, the difference from the first embodiment is that the filter element 32 is a reverse osmosis filter, which is used to filter the raw water from the water supply device 1 to produce pure water and waste water, wherein a portion of the pure water flows into the closed sub-space 35c through the water outlet 321, and the waste water flows into a waste water collection device C through the first water outlet H1 along the first pipeline p1, which is used to collect the waste water generated after the reverse osmosis filter filters the raw water. In this embodiment, the waste water collection device C is a box.

In this embodiment, when the water treatment equipment is in use, the raw water provided by the water supply device 1 flows into the first sub-space 35a from the water inlet H2 via the third pipe p3; the filter element 32 filters the raw water to form pure water, a portion of which flows into the closed sub-space 35c via the water outlet 321, so that the telescopic hose 33 is compressed from the pressure The elastic element 37 is stretched out in a compressed state, thereby compressing the elastic element 37 until pure water can no longer flow into the closed sub-space 35c; the remaining pure water is still in the filter element 32. On the other hand, the waste water generated by the filter element 32 after filtering the raw water flows into the waste water collection device C through the first water outlet H1 along the first pipe p1.

When the user controls the water outlet device 2 to open, the control valve 4 changes from a closed state to an open state, so that the pure water in the closed sub-space 35c flows along the second water outlet H3 to the water outlet device 2, and with the assistance of the force generated by the elastic element 37 changing from a compressed state to an uncompressed state, the telescopic hose 33 is further compressed, so that the pure water in the closed sub-space 35c reaches the water outlet device 2 before the pure water in the filter element 32. In this way, after the user controls the water outlet device 2 to open, the pure water will flow directly from the water outlet device 2 in a very short time or even without delay.

Please refer to Figures 1, 4 and 6. In the present invention, a water purification system is also provided, which includes: the above-mentioned water purification equipment, a flow rate sensing unit 5 and a control device 6. The flow rate sensing unit 5 is arranged in the water purification equipment, and the control device 6 is electrically connected to the control valve 4 and the flow rate sensing unit 5.

The flow rate sensing unit 5 is located in the second pipe p2 and is used to sense the maximum flow rate of pure water flowing through the second pipe p2 to obtain a flow rate value. In this embodiment, the flow rate sensing unit 5 is a Hall water flow sensor for detecting water flow and water flow rate.

The control device 6 has a microcontroller unit 61 and a wireless transmission unit 62. In this embodiment, the control device 6 is a circuit board, which is provided with the microcontroller unit 61 and the wireless transmission unit 62, wherein the microcontroller unit 61 is a microcontroller (MCU), and the wireless transmission unit 62 is a Bluetooth wireless transmission module.

The microcontroller unit 61 is electrically connected to the control valve 4, the flow rate sensing unit 5 and the wireless transmission unit 62, and is used to control the control valve 4 to open or close, and to determine whether the flow rate value is lower than a flow rate threshold value. If the determination result is yes, the microcontroller unit 61 controls the wireless transmission unit 62 to send a notification signal to remind the user that the elastic element 37 needs to be replaced; if the determination result is no, the microcontroller unit 61 does not need to perform additional actions. Among them, when the water outlet device 2 is turned on, the microcontroller unit 61 controls the control valve 4 to open, and when the water outlet device 2 is turned off, the microcontroller unit 61 controls the control valve 4 to close, which belongs to the common knowledge in the technical field of the present invention and will not be elaborated here.

As mentioned above, the telescopic hose 33 has an extension limit. When the telescopic hose 33 is extended to the extension limit, the elastic element 37 has a maximum compression amount. When the elastic element 37 changes from a compressed state to an uncompressed state, the rebound force generated by the maximum compression amount will cause the closed sub-space to 35c of pure water flows to the water outlet device 2 at the flow rate threshold value; when the flow rate value of the pure water is lower than the flow rate threshold value, it means that the elastic element 37 has elastic fatigue, and the rebound force generated by the change from the compressed state to the uncompressed state can no longer make the flow rate value of the pure water reach the flow rate threshold value.

As mentioned above, the filter device of the present invention can retain part of the pure water through the closed sub-space and store most of the pure water in the first sub-space, and open the control valve when the water outlet device is opened, so that the elastic element changes from a compressed state to an uncompressed state, and then compresses the telescopic hose, so that the pure water in the closed sub-space flows along the second water outlet to the water outlet device, and flows to the water outlet device faster than the pure water stored in the first sub-space. In this way, the pure water will flow out directly from the water outlet device without delay. The filter device, water purification device and water purification system of the present invention can achieve the effect of enhancing the user's willingness to use.

The above disclosed implementation forms are only exemplary of the principles, features and effects of the present invention, and are not intended to limit the scope of implementation of the present invention. Anyone familiar with this technology can modify and change the above implementation forms without violating the spirit and scope of the present invention. Any equivalent changes and modifications completed by using the content disclosed in the present invention should still be covered by the scope of the patent application below.
