Easy to operate water purifier

The invention relates to a manual water purifier, and in particular to a water purifier with high water production efficiency, simple structure combination and good sealing performance.

Taiwan's Announcement No. I3181128, "Water Purifier for Operational Use" invention patent, is a patent case that the applicant has previously applied to the bureau and has been approved. The patent discloses a water purifier that can be operated and carried without power, and includes a base, a fixing sleeve fixed on the base and having a first shaft hole, and a shaft is disposed on the first a water production pipe in the shaft hole, a filter unit, a compression sleeve, a pre-filtration unit located above the filter unit, an exhaust unit and a top cover. The filter unit has a plurality of filter bags which are watertightly laminated on the water production pipe, and each filter bag has a drain port communicating with the water production pipe, so that the water body passing through the filter film of the filter bag can be self-contained. The drain port is sent out into the production water pipe. The compression sleeve is movably sleeved on the top end of the fixing sleeve and has a flexing wall defining a second shaft hole, the flexing wall can be freely stretched and compressed, thereby changing the flexing wall The length of the first shaft hole and the second shaft hole define a water-receiving space for accommodating raw water when the compression sleeve is in the stretched state. The exhaust unit is a set of telescopic tube structures and is connected between the water production pipe and the top cover to exclude air inside the water purifier.

In this way, the user pulls out the cap on the top cover and simultaneously presses the manual pressure valve to release the gas existing in the water receiving space, so that the raw water can be poured from the upper water inlet. When filling the water space. When the filtering water is used, the top cover is pressed to urge the flexible wall of the compression sleeve to condense downward to be in a compressed state, so as to exert a pressing force on the raw water in the water-receiving space, thereby causing the water body to pass the pre-heating The filter unit and the filter unit are screened to remove impurities in the water and obtain clean drainage water.

Although the above water purifier can be operated without electric power, there are still some shortcomings:

First, the rate of water production by the water purifier depends entirely on the liquid level of the water-contained space. As a result, the user must continuously supplement the raw water manually, which is inconvenient and passive in water production efficiency. It is only suitable for the operation of low water demand and a few people.

Second, the previous water purifier must use the exhaust unit to discharge the residual air in the production water pipe and the filter bag, resulting in a slightly complicated overall structure, increasing the difficulty of assembly, and because the exhaust unit is a multi-section Telescopic tube structure, so the upper end of the tube body will have a smaller diameter and weaker structural strength. In addition, the compression sleeve adopts a serpentine tube structure, which is easy to produce a yaw due to uneven force application. When the cover condenses the compression sleeve, the skewed compression sleeve will induce the skew of the entire exhaust pipe, so after a period of use, the exhaust pipe may not be smooth in stretching or contracting action. In severe cases, there are many leaks.

3. In the past, the design of the water purifier in the water flow channel is a mode in which the raw water is added above and the filtrate is discharged below. Therefore, before each raw water is replenished, the user must first exhaust the water space. The operation is quite inconvenient, and the gas originally retained in the filter bag and the production pipe still forms a relatively large resistance. The opposite operator must apply more force to overcome the gas resistance and make the residual gas The top of the exhaust unit is discharged, and in addition, the process of producing liquid is inevitable It will make the filtrate directly ejected from the exhaust port at the top of the exhaust pipe, which is not beautiful.

Therefore, the water purifier provided by the invention has the advantages of high water production efficiency, simple structure combination and good sealing performance.

Therefore, the present invention provides a convenient operation water purifier comprising a cylindrical tank, a pre-filtration unit, a membrane filtration unit, a top cover and a manual sputum unit. The trough has a water-receiving chamber formed by a wall, an upper opening opened at the top of the wall to open the water-receiving chamber, and a deep opening from the bottom of the wall A water inlet hole in the water chamber. The pre-filtration unit is detachably mounted in the water-receiving chamber and has a water inlet hole. The pre-filtration unit has at least one box body which forms a watertight function with the inner wall surface of the tube wall, and at least one of the boxes is installed in the box. The filter body in the body comprises at least one spacer net at the top and a plurality of water permeable holes distributed on the spacer net, and the box body can communicate with the water receiving chamber through the water permeable hole. The membrane filtration unit is detachably disposed in the water-receiving chamber and located above the pre-filtration unit, the membrane filtration unit has a bottom-end closed water production pipe and a plurality of water-tight laminated filters disposed on the water production pipe a bag, and the filter bag is disposed perpendicular to an axis of the water production pipe, and each of the filter bag has a liquid production passage communicating with the water production pipe, so that the filtrate after the dialysis filter bag film can be pumped Collected into the production water pipe. The top cover is detachably mounted on the top of the slot to seal the upper opening of the slot, the top cover has a body that is watertightly coupled to the wall, and is disposed in the body The water outlet joint has one end connected to the top end of the water production pipe, and the other end of the water outlet joint extends out of the body to guide the filtrate in the water production pipe to the outside. The manual sputum unit is detachably connected to the water inlet hole of the cylinder groove, and has a water supply tank formed by a flexible wall for temporary storage of raw water, and is oppositely disposed on the sway wall and The sink connection a water nozzle and a pump nozzle, and a water conduit connected to the water outlet and connected to a raw water source, the flexible wall has the ability to move between a compressed state and a stretched state, thereby changing the supplement The water capacity of the water tank, and when the flexing wall is in the extended state, the raw water is driven to be introduced into the water supply tank from the water sump, and when the swaying wall is in the compressed state, the water supply tank is The raw water is pumped into the casing through the pump nozzle, filtered through the membrane filtration unit membrane, and finally the clean filtrate is released from the outlet joint.

It can be seen from the above that when the manual sputum unit is operated, the external raw water can be automatically taken into the sink, and no additional time is needed to supplement the raw water and manual exhaust, so the efficiency of water production. Can be greatly improved, and it is faster and more convenient to use. Since the flow of the water body is a bottom-up mode, the gas remaining in the water-receiving chamber, the production water pipe and the filter bag can be directly and easily discharged from the upper side of the cylindrical tank, so the present invention does not need to provide the conventional exhaust gas. The unit, the overall structure and the assembly are more simplified and convenient. Since the present invention does not need to provide an exhaust unit, and the entire manual sputum unit is separately assembled on the outside of the slot, there is no direct linkage structure between the two, so even if the slanting wall of the manual sputum unit is yawed, It will not affect its operability and the tightness of the groove, and it will not cause leakage.

Shifting (as indicated by the arrow B in Fig. 4) causes the flexing wall 51 to assume the extended state (when the check valve 561 on the pump port 55 of the manual sputum unit 50 is in the closed state), at this time The water supply tank 52 in the movable wall 51 will form a negative pressure suction force due to an increase in volume, and this negative pressure suction force will drive external raw water into the water supply tank 52 from the water discharge port 54. As shown in the first and fifth figures, when the raw water in the fill water tank 52 is filled up to the quantitative amount, the operator pushes the outer pull sleeve 53 inwardly to reverse the displacement (as indicated by the arrow C in FIG. 5). The deflecting wall 51 is brought into the compressed state (at this time, the check valve 56 on the water sluice 54 of the manual sputum unit 50 is in a closed state), by pushing the pressure of the water body of the sleeve 53 The raw water in the water supply tank 52 enters the water-receiving chamber 12 of the cylindrical tank 10 through the pumping port 55, and is pumped into the casing 21 through the water-permeable hole 212 at the bottom of the casing 21, and the casing 21 is utilized. The filter medium 22 is pre-filtered, and then filtered through the membrane of the membrane filtration unit 30, and finally the clean filtrate is released from the outlet joint 42. In this way, the operator can obtain a sufficient filtrate very quickly by performing the reciprocating operation in the above manner.

As shown in Fig. 6, the second embodiment of the convenient operation water purifier of the present invention has the same main structure as the previous embodiment, except that the water inlet 15 of the cylindrical tank 10 is disposed at the wall of the cylinder. The bottom of the pre-filter unit 30 has a double-slot structure. At this time, the manual sputum unit 50 in FIG. 2 is directly screwed onto the water inlet 15 below the cylinder 10. In addition, the top cover 40 can also be pivotally connected to the handle 44, and the user can directly extract the handle 44 to move or carry the entire water purifier.

In summary, the convenient water purifier of the present invention has the following effects and advantages:
