[0003] In use, the user controls the water outlet device to be opened, so that the pure water flows out from the water outlet device and is supplied to the user for drinking. However, since there is a certain water outlet distance between the filtering component and the water outlet device, when the user controls the water outlet device to be opened, there is a certain degree of delay for the pure water to reach the water outlet device from the filtering component. That is to say, after the water outlet device is opened, the pure water will not immediately flow out from the water outlet device, causing the user to have to wait for a period of time before obtaining the pure water, thereby reducing the user's willingness to use.

In addition, in the specification, unless explicitly described to the contrary, the word "comprising" will be understood to mean including the components described, but not excluding any other components.

[0028] Please refer to Figure 1 , which is a schematic structural diagram of the first embodiment of the water purification treatment device of the present invention, including: a water supply device 1, a water outlet device 2 and a filtering device 3, wherein the filtering device 3 is connected to the water supply device 1 and the water outlet device 2.

[0029] 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.

[0030] Please refer to Figure 2 , 3, the filtering device 3 includes a cylinder body 31, a filtering component 32, a telescopic hose 33 and a cover body 34. Among them, an accommodation space 35 is provided inside the cylinder body 31. The cylinder body 35 uses a base 36 to divide the accommodation space 35 into a first sub-space 35a and a second sub-space 35b. In this embodiment, the first sub-space 35a is used to accommodate the filtering component 32, and the second sub-space 35b is used to accommodate the telescopic hose 33. The base 36 has a first communication port 361 and a second communication port 362 that communicate the first sub-space 35a and the second sub-space 35b.

[0031] The cylinder body 31 is provided with a first water outlet H1 and a water inlet H2 that communicate with the first sub-space 35a, and a second water outlet H3 that communicates with the second sub-space 35b via the second communication port 362. In this embodiment, the first water outlet H1 and the second water outlet H3 are respectively connected to the water outlet device 2 via a first pipeline p1 and a second pipeline p2, and the water inlet H2 is connected to the water supply device 1 via a third pipeline p3.

[0032] The filtering component 32 is arranged in the first sub-space 35a and has a water outlet end 321. The water outlet end 321 penetrates through the first communication port 361 and blocks the first communication port 361. In this embodiment, the filtering component 32 is a filter element with several filter materials, which is used to filter the raw water from the water supply device 1 to produce pure water. Among them, the several filter materials may include medical stone, cation resin, activated carbon and far-infrared raw materials to filter the raw water into pure water with better taste and different functional effects.

[0033] The telescopic hose 33 is arranged in the second sub-space 35b and fixed above the base 36. Thereby, the telescopic hose 33 and the base 36 jointly define a closed sub-space 35c communicating with the second water outlet 38 in the second sub-space 35b, which is used to store a part of pure water.

[0034] An elastic component 37 is arranged inside the cover body 34. In this embodiment, the elastic component 37 is a compression spring. The cover body 34 is sleeved on the cylinder body 31, and the elastic component 37 extends into the second sub-space 35b and abuts above the top surface of the telescopic hose 33.

[0035] Specifically, an external thread is provided on the outer wall of one end of the cylinder body 31 closer to the second sub-space 35b, and an internal thread corresponding to the external thread is provided on the inner wall of the cover body 34. The cover body 34 is screwed to the end of the cylinder body 31.

[0036] Preferably, the water purification treatment device of the present invention may further include a control valve 4 disposed in the second pipeline p2 for opening or closing the communication between the closed subspace 35c and the water outlet device 2. In this embodiment, the control valve 4 is a solenoid valve. Specifically, the control valve 4 is used to prevent the pure water located in the closed subspace 35c from directly flowing out through the water outlet device 2.

[0037] In this embodiment, when the water purification treatment device is in use, the raw water provided by the water supply device 1 flows into the first subspace 35a from the water inlet H2 through the third pipeline p3. The filtration assembly 32 filters the raw water to form pure water. A part of the pure water flows into the closed subspace 35c through the water outlet end 321, causing the telescopic hose 33 to be stretched from the compressed state, thereby compressing the elastic assembly 37 until the pure water can no longer flow into the closed subspace 35c; the remaining pure water remains in the first subspace 35a.

[0038] When the diameters and lengths of the first pipeline p1 and the second pipeline p2 are equal, when the user controls the water outlet device 2 to open, the pure water remaining in the first subspace 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 pure water located in the closed subspace 35c flows to the water outlet device 2 along the second water outlet H3, and with the assistance of the force generated when the elastic assembly 37 changes back from the compressed state to the uncompressed state, the telescopic hose 33 is further compressed, so that the pure water located in the closed subspace 35c reaches the water outlet device 2 earlier than the pure water located in the first subspace 35a. Thereby, after the user controls the water outlet device 2 to open, the pure water will flow out directly from the water outlet device 2 very quickly or even without delay.

[0039] Please refer to Figure 4 、 5 , which are respectively the structural schematic diagram of the second embodiment of the water purification treatment device of the present invention and the cross-sectional view of the filtration device of the second embodiment. In this embodiment, the difference compared with the first embodiment is that: the filtration assembly 32 is a reverse osmosis filter for filtering the raw water from the water supply device 1 to produce pure water and waste water. A part of the pure water flows into the closed subspace 35c through the water outlet end 321, and the waste water flows into a waste water collection device C along the first pipeline p1 through the first water outlet H1 for collecting 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.

[0040] In this embodiment, when the water purification treatment device 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 pipeline p3; the filtration component 32 filters the raw water to form pure water, and a part of the pure water flows into the closed sub-space 35c via the water outlet end 321, so that the telescopic hose 33 is stretched from the compressed state, and then compresses the elastic component 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 filtration component 32; on the other hand, the wastewater generated after the filtration component 32 filters the raw water flows into the wastewater collection device C along the first pipeline p1 via the first water outlet H1.

[0041] When the user controls the water outlet device 2 to open, the control valve 4 changes from the closed state to the 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 when the elastic component 37 changes back from the compressed state to the 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 earlier than the pure water in the filtration component 32. Thereby, after the user controls the water outlet device 2 to open, the pure water will flow out directly from the water outlet device 2 with a very short or even no delay.

[0042] Please refer to Figure 1 、 4 And FIGS. 6, in the present invention, a water purification treatment system is further provided, including: the above-mentioned water purification treatment device, a flow rate sensing unit 5 and a control device 6, the flow rate sensing unit 5 is arranged on the water purification treatment device, and the control device 6 is electrically connected to the control valve 4 and the flow rate sensing unit 5.

[0043] The flow rate sensing unit 5 is located in the second pipeline p2 and is used to sense the maximum flow rate of the pure water flowing through the second pipeline p2 to obtain a flow rate value. In this embodiment, the flow rate sensing unit 5 is a Hall water flow sensor used to detect the water flow rate and the water flow velocity.

[0044] 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 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.

[0045] 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 configured to control the opening or closing of the control valve 4, 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 component 37 needs to be replaced; if the determination result is no, the microcontroller unit 61 may 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 is common knowledge in the technical field of the present invention and will not be elaborated here.

[0046] As described above, the telescopic hose 33 has an extension limit. When the telescopic hose 33 extends to the extension limit, the elastic component 37 has a maximum compression amount; when the elastic component 37 changes from the compressed state back to the uncompressed state, the resilience generated by the maximum compression amount will cause the pure water in the closed subspace 35c to flow towards 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 component 37 has experienced elastic fatigue, and the resilience generated when it changes from the compressed state back to the uncompressed state is no longer able to make the flow rate value of the pure water reach the flow rate threshold value.

[0047] As described above, the filtering device of the present invention can retain part of the pure water through the closed subspace, and store most of the pure water in the first subspace. When the water outlet device is turned on, the control valve is opened, so that the elastic component changes from the compressed state back to the uncompressed state, thereby compressing the telescopic hose, and causing the pure water in the closed subspace to flow to the water outlet device along the second water outlet, and faster than the pure water stored in the first subspace flows to the water outlet device. Thereby, the pure water will flow out directly from the water outlet device without delay. The filtering device, the water purification treatment device, and the water purification treatment system of the present invention can achieve the effect of enhancing the user's willingness to use.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
