[0021] Referring to Figures 1, 2, and 3, a lead-removing water purifier for pregnant women includes a kettle body, which includes a body 2 and a lid 1. The lid 1 has a first opening, into which a straw 4 is inserted. The straw 4 is preferably a flexible tube to facilitate drinking for pregnant women, especially while lying in the delivery room. The lead-removing water purifier also includes a filter cartridge 6 containing a lead-removing filter module. A first water outlet is defined at the top of the filter cartridge 6, and a first water inlet is defined on the sidewall of the filter cartridge 6. The lead-removing water purifier also includes a storage box 5 containing minerals 9. A second water inlet is defined at the bottom of the storage box 5, and a second water outlet is defined at the top of the storage box 5. The filter cartridge 6 is detachably connected to the bottom of the storage box 5, connecting the first water outlet and the second water inlet. The storage box 5 is fixedly connected to the straw, connecting the second water outlet and the straw.

[0022] The present invention fixes the filter element 6 below the straw, which has the following advantages compared to the design in which the filter element 6 is fixed below the pot lid 1: 1. It allows the filter element 6 to be easily disassembled and cleaned by adjusting its position; 2. It has no restrictions on the design of the pot lid 1, that is, it allows it to be used on small water purifiers for outdoor use and large water purifiers for home use; 3. It allows the selection of more types of filter elements 6 (especially larger sizes); 4. It changes the filtering during water filling to filtering during water drinking, so that the water can be filtered and drunk at any time, avoiding the secondary pollution that may be caused by not drinking the water for a long time after filling and filtering; 4. The filter element 6 can be kept below the water purifier, so that the filter material used for filtering can be kept moist for a long time, avoiding the problems of cracking of the filter material caused by drying and wetting, shortening of the filter life, weakening of the filtration effect, and entry of filter material particles into the straw. The present invention adds a storage box 5 and optimizes the position of the storage box 5 so that minerals 9 can be added to the filtered water, solving the problem of mineral 9 deficiency in pregnant women.

[0023] About Storage Box 5

[0024] The storage box 5 comprises a tubular inner wall 8, a tubular outer wall 7, an annular top cover, and an annular bottom cover. The inner edge of the top cover connects to the upper portion of the inner wall 8, exposing the top portion of the inner wall 8 to form the second water outlet of the storage box 5. The bottom edge of the inner wall 8 connects to the inner edge of the bottom cover. The outer edge of the top cover connects to the top edge of the outer wall 7, and the outer edge of the bottom cover connects to the lower portion of the outer wall 7, exposing the lower portion of the outer wall 7 to form the second water inlet of the storage box 5. The inner wall 8, outer wall 7, top cover, and bottom cover form a storage bin, in which the minerals 9 are stored. The outer sidewall of the second water outlet is provided with an outwardly protruding annular protrusion 10, and the bottom of the straw is sleeved outside the second water outlet. Threads 11 are provided on either the outer or inner sidewall of the second water inlet, and the filter element 6 is threadedly connected to the second water inlet of the storage box 5.

[0025] Preferably, the inner diameter of the portion of the inner wall 8 below the top cover gradually increases from top to bottom. A first through hole is provided on the portion of the inner wall 8 below the top cover, and a second through hole is provided on the bottom cover. Advantages: 1. Water passes through the second through hole on the bottom cover or the first through hole on the inner wall 8 and enters the storage bin, so that the minerals 9 in the storage bin are dissolved in water and flow out, thereby adding minerals 9 to the water. 2. The inner diameter of the inner wall 8 gradually increases from top to bottom, so that the water in the storage bin is naturally discharged under the action of gravity, avoiding long-term contact of water with the minerals 9 in the storage bin, causing the minerals 9 to be dissolved prematurely or excessively, resulting in a short service life of the storage box 5. 3. Allowing part of the water to be directly sucked out through the straw without passing through the storage bin, thereby reducing the resistance of the water passing through the filter element 6 and the storage box 5 in sequence, avoiding difficulty in sucking.

[0026] The outer wall 7 may be provided with an openable feeding window, through which minerals 9 are added to the storage bin. Preferably, the top cover and the outer wall 7 and the inner wall 8 are detachably connected (threaded, snap-on, etc.), so that materials can be added to the storage bin by opening the top cover. At this time, the outer diameter of the portion of the inner wall 8 located above the top cover preferably remains unchanged from top to bottom, so as to facilitate the insertion of the top cover. The outer diameter of the portion of the inner wall 8 located below the top cover gradually increases from top to bottom. The portion of the inner wall 8 located below the top cover is used to limit the top cover. The upper end face of the top cover is preferably provided with a strip-shaped protrusion, which extends radially along the top cover, and the strip protrusions are evenly distributed around the central axis of the top cover and form a ring. The strip protrusions can thereby be used to more easily rotate the top cover.

[0027] About filter element 6

[0028] The filter element 6 contains a filter module for lead removal. The filter module is preferably a tubular activated carbon filter rod 13. A first water outlet is provided at the top of the filter element 6, and a first water inlet is provided on the side wall of the filter element 6. The present invention adopts a side-inlet and top-outlet water outlet method, which has a large water inlet area and can be combined with a method of filtering while drinking through a straw. Preferably, a filter screen or ultrafiltration module is sandwiched between the activated carbon filter rod 13 and the first water outlet. The filter screen is thereby used to prevent particles that fall from the activated carbon filter rod 13 from entering the straw.

[0029] The top of the filter element 6 is provided with an upward extension, and the extension is provided with a thread matching the second water inlet of the storage box 5, so that the storage box 5 is threadedly connected, making the two detachable, thereby solving the problem that the one with longer life cannot be effectively utilized when the two are fixedly connected due to their different lifespans.

[0030] Preferably, a gap is provided between the first water outlet and the second water inlet to temporarily store filtered water or the minerals 9 that have flowed out. More importantly, the water in the storage box 5 is allowed to drain completely, thus preventing the minerals 9 from being soaked in water for a long time. An upward extension 12 is provided at the first water outlet, forming a weir to limit the amount of minerals 9 that flow back from the first water outlet into the filter element 6.

[0031] About the pot body 2, the pot lid 1

[0032] A pot bottom 3 is provided below the pot body 2. A first magnetic sheet in the form of a disc is preferably fixed below the pot bottom 3. A second magnetic sheet in the form of a ring is preferably provided at the bottom of the filter element 6. The magnetism of the first magnetic sheet is opposite to that of the second magnetic sheet. This solution selects the position and shape of the magnetic sheet, which has the following advantages: 1. The bottom of the filter element 6 is magnetically attracted to the bottom of the pot body 2, which can alleviate the shaking and displacement of the filter element 6; 2. The magnetic sheet at the bottom of the filter element 6 is ring-shaped. On the one hand, it can balance the magnetic force on the filter element 6 and alleviate the shaking and displacement of the filter element 6. On the other hand, it can reduce the weight of the filter element 6 and facilitate the removal or cleaning of the filter element 6; 3. The filter element 6 can be adsorbed on the bottom of the pot body 2, so that the filter element 6 is more easily and longer in contact with water. 4. The magnetic sheet can be used to assist the water in the water purification pot in absorbing metal ions and magnetizing the water source.

[0033] Preferably, an annular notch is provided at the outer edge of the bottom of the filter element 6, and the second magnetic sheet 14 is snapped into the annular notch. This allows the area of ​​the second magnetic sheet 14 to be larger. To prevent the filter element 6 from rotating, a third magnetic sheet 15 can be added to the bottom of the filter element 6. The magnetic properties of the third magnetic sheet 15 are the same as those of the second magnetic sheet. Preferably, there are two third magnetic sheets 15, both cylindrical in shape. The cylindrical third magnetic sheets are partially embedded in the filter element 6 and partially inserted into a limit recess with an upward opening on the bottom of the pot. Both third magnetic sheets are preferably located inside the second magnetic sheet, with a gap between them.

[0034] The lid 1 is preferably threadedly connected to the body 2, so as to facilitate disassembly between the two. The present invention does not provide an additional opening on the lid 1, and directly uses the mouth of the body 2 as the water inlet, which has a larger water injection area.
