[0002] Direct drinking water refers to drinking water that has undergone deep purification treatment to meet the standards for direct consumption. Common sources of direct drinking water include piped drinking water, household water purifiers, and direct drinking water machines. Direct drinking water is pure, convenient, and safe, but it has a low mineral content. Therefore, mineralization filters are usually installed in direct drinking water equipment, and essential minerals (such as calcium, magnesium, potassium, and sodium) are artificially added.
[0003] Because the mineralization filter cartridge of household direct drinking water equipment has a long replacement cycle, usually between 6 months and 2 years, when residents are away for a period of time and the household direct drinking water equipment is not used for several weeks, the mineralization filter cartridge is in a damp state, and bacteria multiply rapidly. When residents return home, since it is not yet time for the mineralization filter cartridge to be replaced, it is very easy for them to drink direct drinking water containing a lot of bacteria, which is not good for their health. Utility Model Content
[0004] The purpose of this invention is to solve the problem that bacteria easily grow in the mineralized filter element of household direct drinking water equipment when it is not used for a long time, and to propose a direct drinking water mineralized bidirectional filter element assembly.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A direct drinking water mineralization bidirectional filter cartridge assembly includes a direct drinking water device body, a water pipe for inputting direct drinking water is provided inside the direct drinking water device body, a mineralization filter cartridge for mineralizing direct drinking water is installed inside the direct drinking water device body, and a filter cartridge mechanism is provided between the direct drinking water device body and the mineralization filter cartridge;
[0007] The filter element mechanism includes a servo motor connected to the main body of the direct drinking water device. The output end of the servo motor is connected to a conversion plate. Two mounting cavities are symmetrically arranged in the conversion plate. Both mounting cavities are slidably connected to the mineralized filter element. Two trapezoidal blocks are symmetrically slidably connected in the mounting cavities. A first spring is provided in the trapezoidal blocks and the mounting cavities.

The inner side of the circular groove is provided with a plurality of first water passage holes, which are slidably connected to the sealing plate.
[0009] Preferably, the width of the first water passage hole is smaller than the width of the sealing plate, and a plurality of plastic support rods are provided between the sealing plate and the bottom of the circular groove.
[0010] Preferably, the connecting assembly includes a water delivery end connected to one end of a water pipe, the water delivery end having a connector and a plurality of first pipes connected to the connector and the plurality of first pipes, the first pipes having a conical groove, a blocking plate slidably connected in the conical groove, a second spring and a piezoelectric ceramic trigger being provided between the blocking plate and the conical groove, the piezoelectric ceramic trigger being electrically connected to a servo motor, and the water delivery end having a circular groove, a concave rod slidably connected in the circular groove.
[0011] Preferably, a second conical block is slidably connected within the interface, the second conical block is slidably connected to the first conical block, and a third spring is provided within the interface between the second conical block and the interface.

[0014] Preferably, both ends of the mineralized filter element and the lower end of the water supply end are provided with guide grooves, and the guide groove at the lower end of the water supply end is slidably connected to the first conical block.
[0015] Compared with the prior art, this utility model provides a direct drinking water mineralization bidirectional filter cartridge assembly, which has the following beneficial effects:
[0016] 1. This direct drinking water mineralization bidirectional filter element assembly, during the use of the main body of the direct drinking water equipment, the blocking plate moves in the conical groove and repeatedly contacts the piezoelectric ceramic trigger for timing. When the timing time exceeds one week, the servo motor is triggered to rotate and replace the mineralization filter element. This makes it convenient for residents to drink sterile mineralized direct drinking water after being away from home for a long time, which helps protect the drinking water safety of residents.
[0017] 2.

[0026] Reference Figure 1-5A direct drinking water mineralization bidirectional filter cartridge assembly includes a direct drinking water device body 1. After deep purification of residents' domestic water to a level suitable for direct consumption, the drinking water is then passed through a mineralization filter cartridge 3, resulting in water containing minerals. The direct drinking water device body 1 has a water pipe 2 for inputting the drinking water, guiding the purified water into the water inlet 501 and the mineralization filter cartridge 3. The mineralization filter cartridge 3, containing natural minerals and mineral extracts, is installed within the direct drinking water device body 1, ensuring the drinking water contains minerals. A filter cartridge mechanism 4 is located between the direct drinking water device body 1 and the mineralization filter cartridge 3, which can record the unused time of the direct drinking water device body 1 in segments. If the direct drinking water device body 1 has been unused for more than a week, the mineralization filter cartridge 3 is automatically replaced, improving the ability of residents to drink healthy, unpolluted water after long periods of absence, thus protecting residents' daily drinking water safety.
[0027] The filter element mechanism 4 includes a servo motor 401 connected to the main body 1 of the direct drinking water equipment. When the blocking plate 505 is attached to one side of the conical groove 504 under the action of the second spring 506, it applies pressure to the piezoelectric ceramic trigger 507, causing the piezoelectric ceramic trigger 507 to start timing. After the timing reaches one cycle, it outputs an electrical signal to the servo motor 401. After being triggered once, the servo motor 401 drives its output shaft to rotate 180 degrees with the conversion plate 402, replacing the spare mineralized filter element 3 at the other end of the conversion plate 402 to the water supply end 501, ensuring that the direct drinking water passes through the sterile mineralized filter element 3. The output end of the servo motor 401 is connected to the conversion plate 402. The middle part of 402 is connected to the output end of servo motor 401, so that the conversion plate 402 rotates around the middle part. Two installation cavities 403 are symmetrically arranged inside the conversion plate 402. Residents can put two sterile mineralized filter cartridges 3 into the installation cavities 403 at one time. While using one, they can keep the other as a backup in case of emergency to ensure their drinking water safety. Both installation cavities 403 are slidably connected to the mineralized filter cartridges 3. Two trapezoidal blocks 404 are symmetrically slidably connected inside the installation cavities 403. The two sides of the trapezoidal blocks 404 are inclined. The trapezoidal blocks 404 and the installation cavities 403 are provided with a first spring 405. The main body 1 of the direct drinking water equipment is provided with a connecting component 5, which can replace the mineralized filter cartridges 3 that are connected to the water supply end 501.
[0028] The surface of the mineralizing filter element 3 is symmetrically provided with two arc grooves 301. The two ends of the arc grooves are inclined, which press against the inclined surfaces at both ends of the trapezoidal block 404, promoting the trapezoidal block 404 to press the first spring 405 into the mounting cavity 403, thereby releasing the fixing restriction of the mounting cavity 403 on the mineralizing filter element 3. The arc grooves 301 and the trapezoidal block 404 are slidably connected. The upper end surface of the mineralizing filter element 3 is provided with a circular groove 302. A rubber gasket is provided between the circular groove 302 and the interface 502 to increase the sealing performance and prevent water leakage between the water supply end 501 and the mineralizing filter element 3. 02 is the same size as the interface 502. A sealing plate 303 is slidably connected inside the circular groove 302. The circular groove 302 has a certain depth. When the mineralizing filter element 3 is not in use, the sealing plate 303 is located at the position of the first water passage hole 305 inside the circular groove 302 and completely blocks the first water passage hole 305. At this time, the sealing plate 303 and the disposable plastic support rod 306 at the bottom of the circular groove 302 can support the sealing plate 303. The height position of the first conical block 304 at the upper end of the sealing plate 303 is above the mineralizing filter element 3. The upper end of the sealing plate 303 is connected to the first conical block 304. The first conical block 304 has a circular inclined surface on its surface. Multiple first water passage holes 305 are provided inside the circular groove 302 to introduce drinking water from the water supply end 501 into the mineralizing filter element 3. The first water passage holes 305 are slidably connected to the sealing plate 303. The width of the first water passage hole 305 is smaller than the width of the sealing plate 303. Multiple plastic support rods 306 are provided between the sealing plate 303 and the bottom of the circular groove 302. Guide grooves 512 are provided at both ends of the mineralizing filter element 3 and at the lower end of the water supply end 501. When the unused mineralizing filter element 3 is replaced with water from the water supply end... When 501 is connected, the first conical block 304 above the mineralizing filter element 3 contacts the guide groove 512 at the lower end of the water supply end 501 first, pressing the first conical block 304 and the sealing plate 303 to stand still at the bottom of the circular groove 302. At this time, the plastic support rod 306 breaks and the first water passage 305 is fully open, so that the spare mineralizing filter element 3 can remain sterile and clean when not in use. During the replacement of the spare mineralizing filter element 3, the unopened mineralizing filter element 3 is opened, and the guide groove 512 at the lower end of the water supply end 501 is slidably connected to the first conical block 304.
[0029] The connecting component 5 includes a water inlet 501 connected to one end of the water pipe 2. The water inlet 501 is made entirely of antibacterial material, and both its interior and outlet are sealed to prevent leakage. The water inlet 501 contains a connector 502 and multiple first pipes 503. The first pipes 503 are connected to the water pipe 2 of the water inlet 501, introducing drinking water into the mineralizing filter element 3. A second conical block 510 is slidably connected inside the connector 502. Under the action of a third spring 511, one end of the second conical block 510 extends beyond the horizontal height of the connector 502. When the spare mineralizing filter element 3 rotates and accurately aligns with the connector 502, the stationary first conical block 304 presses against the second conical block 510, compressing the third spring 511 and causing it to move into the circular groove 302, thereby driving the concave rod 509. One end separates from the blocking plate 505, releasing the movement restriction on the blocking plate 505. At this time, the main body 1 of the direct drinking water equipment can be used normally. The second conical block 510 is slidably connected to the first conical block 304. The second conical block 510 and the interface 502 are provided with a third spring 511. The interface 502 is connected to multiple first pipes 503. The first pipes 503 are provided with conical grooves 504. The blocking plate 505 is slidably connected in the conical grooves 504. When the main body 1 of the direct drinking water equipment has not been used for a long time, the servo motor 401 is triggered to work. During the process of separating the mineralized filter element 3 being used from the interface 502, the second conical block 510 separates from the first conical block 304. Under the action of the third spring 511, the second conical block 510 drives the concave rod 509 to move. This causes one end of the concave rod 509 to press against one side of the blocking plate 505, thereby sealing the first pipeline 503 and preventing the direct drinking water in the first pipeline 503 from leaking and being wasted during the automatic replacement of the mineralized filter element 3. A second spring 506 and a piezoelectric ceramic trigger 507 are provided between the blocking plate 505 and the conical groove 504. The piezoelectric ceramic in the piezoelectric ceramic trigger 507 generates an electrical signal under pressure, thereby triggering the piezoelectric ceramic trigger 507 to start timing. After the timing limit is manually set to one week, an electrical signal is transmitted to the servo motor 401 after the timing limit is reached, thereby triggering the servo motor 401 to work. The piezoelectric ceramic trigger 507 is electrically connected to the servo motor 401. A circular groove 508 is provided in the water delivery end 501, and the concave rod... The two ends of the concave rod 509 are round rods that slide linearly in the round rod groove inside the water supply end 501. Rubber pads are placed between the round rods at both ends of the concave rod 509 and the round groove 302 inside the water supply end 501 to prevent drinking water from entering the round groove 508 through the round rod groove. The concave rod 509 moves linearly within the round groove 508 along the direction of its two ends, causing one end of the concave rod 509 to contact or separate from the blockage plate 505. The width of the round groove 508 is greater than the width of the crossbar of the concave rod 509. The concave rod 509 is slidably connected within the round groove 508. The two ends of the concave rod 509 pass through the conical groove 504 and the interface 502, respectively. When the mineralizing filter element 3 is connected to the interface 502, the second conical block 510 causes one end of the concave rod 509 to separate from the blockage plate 505.When replacing the mineralizing filter element 3, the second conical block 510, under the action of the third spring 511, drives the concave rod 509 and one end thereto contact the blocking plate 505. This restricts the movement of the blocking plate 505 within the conical groove 504 due to water pressure, thus reducing the occurrence of drinking water leakage between the first pipeline 503 and the interface 502 during automatic replacement of the mineralizing filter element 3, reducing the waste of drinking water. Furthermore, one end of the concave rod 509 is connected to the second conical block 510, and the end of the concave rod 509 away from the second conical block 510 is slidably connected to the blocking plate 505.
[0030] In this invention, two brand-new mineralized filter elements 3 are placed into the two mounting cavities 403 within the conversion plate 402. The blocking plate 505 reciprocates within the conical groove 504, triggering the piezoelectric ceramic trigger 507 for timing at any time. When the blocking plate 505 is in contact with the piezoelectric ceramic trigger 507 for an extended period and the timing exceeds one week, the contaminated mineralized filter element 3 is replaced with a brand-new one. This helps protect the safety of drinking water for residents. At this time, the servo motor 401 drives the conversion plate 402 and the mineralized filter element 3 to rotate, separating the contaminated mineralized filter element 3 from the rotating interface 502. The second conical block 510, under the action of the third spring 511, drives the concave rod 509, causing one end of the concave rod 509 to press against one side of the blocking plate 505, preventing the blocking plate 505 from moving. At this time, there is no drinking water in the interface 502. When the brand-new mineralized filter element 3 rotates... When the interface 502 comes into contact with the connecting port 502, the guide groove 512 at the lower end of the water supply end 501 squeezes the first conical block 304 above the mineralization filter element 3, causing multiple plastic support rods 306 to break. The sealing plate 303 moves towards the bottom of the circular groove 302 and opens the first water passage 305, which helps to keep the spare mineralization filter element 3 in a sterile state before use. When the connecting port 502 is connected to the circular groove 302, the first conical block 304 squeezes the second conical block 510 and compresses the third spring 511, causing one end of the concave rod 509 to separate from the blocking plate 505. At this time, the drinking water in the first pipeline 503 can push the blocking plate 505 to move in the conical groove 504 under water pressure, which helps to keep the main body 1 of the drinking water equipment working normally after the mineralization filter element 3 is replaced. This makes it convenient for residents to drink sterile mineralized drinking water after being away from home for a long time and returning home, which helps to protect the drinking water safety of residents.
