[0003] In use, the user controls the water outlet device to open, allowing purified water to flow out and be supplied to the user for drinking. However, due to the distance between the filter assembly and the water outlet device, there is a certain delay in the purified water reaching the outlet device after the user opens it. That is, the purified water does not flow out immediately after the device is opened, requiring the user to wait for a period of time to obtain the purified water, thus reducing the user's willingness to use the device.

[0004] In view of this, it is necessary to provide a filtration device to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them.

Additionally, in this specification, unless explicitly stated otherwise, the word "comprising" will be understood to mean including the stated components but not excluding any other components.

[0028] Please refer to Figure 1 The diagram shows 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.

[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 and Figure 3The filtering device 3 includes a cylindrical body 31, a filtering assembly 32, a telescopic hose 33, and a cover 34. The cylindrical body 31 has an internal accommodating space 35. A base 36 divides the accommodating space 35 into a first subspace 35a and a second subspace 35b. In this embodiment, the first subspace 35a is used to accommodate the filtering assembly 32, and the second subspace 35b is used to accommodate the telescopic hose 33. The base 36 has a first connecting port 361 and a second connecting port 362 connecting the first subspace 35a and the second subspace 35b.

[0031] The cylinder 31 has a first water outlet H1 and a water inlet H2 that connect to the first subspace 35a, and a second water outlet H3 that connects 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 respectively connected to the water outlet device 2 via a first pipe p1 and a second pipe p2, and the water inlet H2 is connected to the water supply device 1 via a third pipe p3.

[0032] The filter assembly 32 is disposed in the first subspace 35a and has a water outlet 321. The water outlet 321 extends through the first connecting port 361 and blocks the first connecting port 361. In this embodiment, the filter assembly 32 is a filter cartridge with several filter media, used to filter the raw water from the water supply device 1 to produce pure water. The several filter media may include maifan stone, cation exchange 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 disposed in the second subspace 35b and fixed above the base 36. Therefore, the telescopic hose 33 and the base 36 together define a closed subspace 35c in the second subspace 35b, which is connected to the second water outlet H3, for pre-storing some pure water.

[0034] The cover 34 has an elastic component 37 inside, which is a compression spring in this embodiment. The cover 34 is sleeved on the cylinder 31, and the elastic component 37 extends into the second subspace 35b and abuts against the top surface of the telescopic hose 33.

[0035] Specifically, the outer wall of the end of the cylinder 31 that is closer to the second subspace 35b is provided with an external thread, and the inner wall of the cover 34 is provided with an internal thread corresponding to the external thread. The cover 34 is screwed to the end of the cylinder 31.

[0036] Preferably, the water purification device of the present invention may further include a control valve 4, disposed in the second pipeline p2, for opening or closing the connection between the enclosed 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 pure water located in the enclosed subspace 35c from flowing directly out of the water outlet device 2.

[0037] 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 subspace 35a from the inlet H2 via the third pipeline p3. The filter component 32 filters the raw water to form pure water. A portion of the pure water flows into the closed subspace 35c via the outlet 321, causing the telescopic hose 33 to be stretched from a compressed state, thereby compressing the elastic component 37 until pure water can no longer flow into the closed subspace 35c; the remaining pure water remains in the first subspace 35a.

[0038] 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 subspace 35a flows to the water outlet device 2 through the first outlet H1. At the same time, the control valve 4 changes from a closed state to an open state, allowing the pure water in the closed subspace 35c to flow to the water outlet device 2 along the second outlet H3. Furthermore, with the assistance of the force generated by the elastic component 37 changing from a compressed state to an uncompressed state, the telescopic hose 33 is compressed, causing the pure water in the closed subspace 35c to reach the water outlet device 2 before the pure water in the first subspace 35a. Therefore, after the user controls the water outlet device 2 to open, pure water will flow out of the water outlet device 2 in a very short time, or even without delay.

[0039] Please refer to Figure 4 and Figure 5 The figures are a schematic diagram of the second embodiment of the water purification equipment of the present invention and a cross-sectional view of the filtration device of the second embodiment. In this embodiment, the difference from the first embodiment is that the filtration component 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 wastewater. A portion of the pure water flows into the closed subspace 35c through the outlet 321, and the wastewater flows into a wastewater collection device C through the first outlet H1 along the first pipeline p1 to collect the wastewater produced by the reverse osmosis filter after filtering the raw water. In this embodiment, the wastewater collection device C is a box.

[0040] In this embodiment, when the water purification equipment is in use, the raw water supplied by the water supply device 1 flows into the first subspace 35a from the inlet H2 via the third pipeline p3; the filter assembly 32 filters the raw water to form pure water, a portion of which flows into the closed subspace 35c via the outlet 321, causing the telescopic hose 33 to be stretched from a compressed state, thereby compressing the elastic component 37 until pure water can no longer flow into the closed subspace 35c; the remaining pure water remains inside the filter assembly 32; on the other hand, the wastewater generated by the filter assembly 32 after filtering the raw water flows into the wastewater collection device C via the first outlet H1 along the first pipeline p1.

[0041] When the user controls the water outlet device 2 to open, the control valve 4 changes from a closed state to an open state, allowing the pure water in the enclosed subspace 35c to flow along the second water outlet H3 to the water outlet device 2. Furthermore, with the assistance of the force generated by the elastic component 37 changing from a compressed state back to an uncompressed state, the telescopic hose 33 is compressed, causing the pure water in the enclosed subspace 35c to reach the water outlet device 2 before the pure water in the filter assembly 32. Therefore, after the user controls the water outlet device 2 to open, pure water will flow directly from the water outlet device 2 with a very short time or even no delay.

[0042] Please refer to Figure 1 , Figure 4 and Figure 6 In this invention, a water purification system is also provided, comprising: the above-mentioned water purification equipment, a flow rate sensing unit 5 and a control device 6, wherein the flow rate sensing unit 5 is disposed 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.

[0043] The flow rate sensing unit 5 is located in the second pipeline p2 and is used to sense the maximum flow rate of pure water flowing through the second pipeline p2 in order to obtain a flow rate value. In this embodiment, the flow rate sensing unit 5 is a Hall effect water flow sensor used to detect water flow rate and water 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 with the microcontroller unit 61 and the wireless transmission unit 62. 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 used to control the opening and closing of the control valve 4, and to determine whether the flow rate value is lower than a flow rate threshold. 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 does not need to perform any additional actions. It is common knowledge in the technical field of this invention that the microcontroller unit 61 controls the control valve 4 to open when the water outlet device 2 is open, and controls the control valve 4 to close when the water outlet device 2 is closed, and will not be elaborated further here.

[0046] As described above, the telescopic hose 33 has an extension limit. When the telescopic hose 33 is extended to the extension limit, the elastic component 37 has a maximum compression. When the elastic component 37 changes from a compressed state back to an uncompressed state, the rebound force generated by the maximum compression will cause the pure water in the enclosed subspace 35c to flow towards the water outlet device 2 at the flow rate threshold value. When the flow rate of the pure water is lower than the flow rate threshold value, it indicates that the elastic component 37 has experienced elastic fatigue, and the rebound force generated by its change from a compressed state back to an uncompressed state is no longer sufficient to make the flow rate of the pure water reach the flow rate threshold value.

[0047] As described above, the filtration device of the present invention can retain a portion of pure water through the enclosed subspace and store most of the pure water in the first subspace. When the water outlet device is opened, the control valve is activated, causing the elastic component to change from a compressed state to an uncompressed state, thereby compressing the telescopic hose. This allows the pure water located in the enclosed subspace to flow along the second outlet to the water outlet device, and this process is faster than the flow of pure water stored in the first subspace to the water outlet device. Therefore, pure water will flow directly from the water outlet device without delay. The filtration device, water purification device, and water purification system of the present invention can enhance the user's willingness to use them.

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