DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] The water purifier with anti-detachment joint of the present invention is as follows Figures 1 to 4 As shown, the water purifier body 1 includes a water inlet connector 2 for connecting to a faucet. The water purifier body 1 is provided with a water passage cavity 100 for accommodating the filter element assembly 6. The water inlet connector 2 is connected to the water passage cavity 100. In other words, tap water can flow into the water passage cavity 100 through the water inlet connector 2, and the water flow then passes through the filter element assembly 6. The water purifier body 1 is provided with a screw button block 137, as shown in FIG. Fig. 9 and Fig.10 As shown, a screw groove 211 is provided on the outer side of one end of the water inlet joint 2, and the screw groove 211 is buckled with the corresponding screw block 137, as shown in FIG. Figure 3 and Figure 5 As shown, the water purifier body 1 is provided with a slide groove 101. Figure 4 As shown, a locking block 3 is slidably arranged in the slide groove 101. Fig. 9 As shown, the water inlet joint 2 is provided with a circumferential positioning groove 201. Figure 4 As shown, one end of the locking block 3 is placed in the circumferential positioning groove 201, specifically, the end of the locking block 3 away from the center of the water purifier body 1 is placed in the circumferential positioning groove 201, the locking block 3 can slide away from the circumferential positioning groove 201, and the water inlet connector 2 can be detached from the water purifier body 1.

[0030] like Figure 4As shown, one end of the hose 99 is connected to the kitchen faucet, and the other end of the hose 99 is connected to the support tube portion 22 of the water inlet connector 2. Specifically, the hose 99 is sleeved outside the support tube portion 22, and the support tube portion 22 makes the hose 99 partially bulge. The clamping screw cover 23 of the water inlet connector 2 has an inner conical surface, and the inner conical surface of the clamping screw cover 23 is pressed on the bulging part of the hose 99, so that the inner wall of the hose 99 is tightly attached to the support tube portion 22 to achieve a sealed connection. Figure 4 As shown, since the locking block 3 is slidably arranged in the slide groove 101, and one end of the locking block 3 is placed in the circumferential positioning groove 201, when the water inlet connector 2 is rotated, the locking block 3 will block the water inlet connector 2, preventing the water inlet connector 2 from being rotated and causing the screw groove 211 to be disengaged from the corresponding screw block 137, thereby preventing the water inlet connector 2 from rotating due to misoperation or collision, resulting in an unstable connection between the water inlet connector 2 and the water purifier body 1 and water leakage; when the water purifier of the present invention needs to be moved away, first remove the water inlet connector 2, then remove the water inlet connector 2, and then remove the water purifier body 1. The lock block 3 is pushed inwards to disengage the outer end of the lock block 3 from the circumferential positioning groove 201 of the water inlet connector 2, thereby unlocking the water inlet connector 2. The water inlet connector 2 is then rotated counterclockwise by hand to disengage the screw groove 211 from the screw block 137, and the water inlet connector 2 is then pulled outwards away from the water purifier body 1. In other words, the water purifier body 1 is completely separated from the hose 99 and the kitchen faucet, so that the water purifier body 1 can be moved to a corner of a cabinet countertop or stored away. When the water purifier of the present invention is needed, Fig.10 As shown, an avoidance position 213 is formed on the outer side of the water inlet connector 2, and the notch 2111 of the screw groove 211 is connected to the avoidance position 213, so the avoidance position 213 of the water inlet connector 2 is aligned with the screw block 137, and then the water inlet connector 2 is moved toward the water purifier body 1, so that the screw block 137 is aligned with the notch 2111 of the screw groove 211, and then the water inlet connector 2 is rotated clockwise to make the screw block 137 relatively screwed into the corresponding screw groove 211, so at this time, pulling the water inlet connector 2 outward will be blocked by the screw block 137, and then the locking block 3 is pulled outward so that the outer end of the locking block 3 slides into the circumferential positioning groove 201 of the water inlet connector 2, so that the water inlet connector 2 is locked. As can be seen from the above, the water purifier of the present invention can be easily separated from or connected to the hose 99 (and the faucet), and when the water purifier is connected to the hose 99, the connection between the water inlet connector 2 and the water purifier body 1 is reliable, which can prevent the water inlet connector 2 from loosening and leaking. Therefore, the water purifier of the present invention is easy to use and has good reliability.

[0031] Furthermore, if Figures 1 to 5 As shown, the water purifier body 1 includes a sleeve 13 and a base 11 for being placed on a cabinet countertop. The water purifier body 1 also includes a cover 12. The lower end of the cover 12 is connected to the upper end of the base 11. The cover 12 and the base 11 enclose the above-mentioned water passage cavity 100. Figure 3As shown, the filter element assembly 6 is disposed in the water passage cavity 100, the lower end of the filter element assembly 6 is connected to one end of the water outlet pipe disposed in the base 11, and the other end of the water outlet pipe is connected to the water outlet faucet 5. Figure 5 As shown, the base 11 is formed with a mounting cavity 103, and the mounting cavity 103 is a cylindrical cavity. Figure 6 and Figure 7 As shown, one end of the sleeve 13 is formed with a sleeve portion 131, and the sleeve portion 131 is cylindrical. Figure 4 As shown, the housing portion 131 is adapted to be disposed in the mounting cavity 103. Figure 6 As shown, the screw-in block 137 is formed on the inner wall of the housing portion 131. Fig. 9 As shown, the water inlet joint 2 is formed with a connecting pipe portion 21, a screw groove 211 is formed on the outer wall of the connecting pipe portion 21, and one end of the water channel 202 inside the water inlet joint 2 is located at the center of the connecting pipe portion 21, as shown in FIG. Figure 4 As shown, the other end of the water channel 202 is located at the center of the supporting pipe portion 22, and the connecting pipe portion 21 is perpendicular to the supporting pipe portion 22, so the water channel 202 is in a right angle shape; Figure 4 As shown, the connecting pipe portion 21 is disposed in the casing portion 131. Figure 1 and Figure 2 As shown, the buckle structure of the combination of the screw groove 211 and the screw block 137 is a built-in structure, which is conducive to making the appearance of the water purifier simple. By providing the sleeve 13, it is avoided that the screw block 137 needs to be formed on the base 11, which makes mold manufacturing difficult and increases costs. Figure 5 As shown, the slide groove 101 can be formed on the base 11 , and the opening of the slide groove 101 is connected to the installation cavity 103 . The simple structure enables the locking block 3 to be connected to the circumferential positioning groove 201 .

[0032] Furthermore, if Figure 7 As shown, the other end of the sleeve 13 is formed with an inserting portion 132. Figure 5 As shown, the base 11 is formed with a water inlet pipe shell 102, and the water inlet pipe shell 102 is connected to the installation cavity 103. Specifically, a water through hole is formed in the water inlet pipe shell 102, and the water through hole is coaxially arranged with the inner wall of the installation cavity 103. Figure 4 As shown, the inserting pipe portion 132 is inserted into the water inlet pipe shell portion 102, as shown in FIG. Figure 7 As shown, an elastic buckle 133 is formed at the end of the inserting tube portion 132, and a notch 134 is formed on the inserting tube portion 132. The notch 134 penetrates the elastic buckle 133. Figure 4As shown, the elastic buckle 133 is buckled with the inner end of the water inlet pipe shell 102; in the process of assembling the sleeve 13, the pipe insertion part 132 is inserted into the water inlet pipe shell 102, so that the outer end opening of the above-mentioned water through hole of the water inlet pipe shell 102 squeezes the elastic buckle 133, and due to the provision of the notch 134, the elastic buckle 133 is easy to elastically shrink toward the center of the pipe insertion part 132, so that the elastic buckle 133 can slide into and pass through the water inlet pipe shell 102, so that the sleeve part 131 is inserted into the installation cavity 103 at the same time, when the elastic buckle 133 passes over the inner end of the above-mentioned water through hole of the water inlet pipe shell 102, the elastic buckle 133 elastically recovers and opens, so that the elastic buckle 133 is buckled with the inner end of the water inlet pipe shell 102, and at this time, the sleeve 13 pulled outward will be blocked by the inner end of the water inlet pipe shell 102, so that the sleeve 13 and the base 11 are simply and conveniently assembled.

[0033] Furthermore, if Figure 5 As shown, the installation cavity 103 is formed with a cavity bottom 104, and the cavity bottom 104 is formed with a positioning groove 1041. Figure 7 As shown, the sleeve 13 is formed with a positioning protrusion 135. Specifically, a step plate portion 138 is formed between the sleeve shell portion 131 and the insertion tube portion 132, and the positioning protrusion 135 is formed on the back of the step plate portion 138; Figure 4 As shown, the back side of the step plate portion 138 is abutted against the cavity bottom 104, and the positioning protrusion 135 is arranged in the positioning groove 1041, so that the sleeve 13 and the base 11 can be positioned in the circumferential direction around the axis of the shell portion 131, and the positioning protrusion 135 can be symmetrically distributed on both sides of the axis of the shell portion 131, thereby preventing the sleeve 13 from being rotated and causing the position of the spin block 137 to change, so that after the water inlet connector 2 is separated from the water purifier body 1, the spin block 137 can be stabilized at a circumferential position, avoiding the difficulty of alignment when the water inlet connector 2 needs to be connected to the water purifier body 1.

[0034] Furthermore, if Figure 6 As shown, a guide protrusion 136 is formed on the outer side of the casing portion 131. Figure 8 As shown, the locking block 3 is formed with a guide groove 321. Figure 4 and Fig.11 As shown, the guide protrusion 136 is arranged in the guide groove 321. Specifically, the locking block 3 is arranged to slide along a direction parallel to the axis of the connecting pipe portion 21. Figure 8 As shown, the locking block 3 includes a sliding plate portion 31 and a locking plate portion 32. Fig.11 As shown, the slide plate portion 31 is specifically arranged in the slide groove 101, the lock plate portion 32 is arranged in the circumferential positioning groove 201, and the guide groove 321 is specifically formed on the lock plate portion 32; by setting the guide protrusion 136, the sliding guide effect on the lock block 3 is enhanced, so that the lock block 3 can be locked or unlocked flexibly for easy operation.

[0035] Furthermore, if Figure 8 As shown, the outer end of the locking block 3 is formed with a handle piece 33 (the "outer end" mentioned here refers to the end of the locking block 3 away from the center of the base 11), as shown in FIG. Figure 4 As shown, the handle piece 33 is arranged outside the slide groove 101, so that the user can use the fingernail to push the handle piece 33 to lock or unlock the lock block 3. Specifically, the handle piece 33 can be perpendicular to the slide plate part 31 and the handle piece 33 is arranged downward.

[0036] In some embodiments, Figure 6 As shown, a blocking slot 1371 is formed on the rotary buckle block 137. Fig. 9 As shown, a block 2112 is formed in the screw groove 211. Fig.11 As shown, the block 2112 is arranged in the blocking slot 1371. Therefore, when the lock block 3 is unlocked, when the water inlet connector 2 is rotated counterclockwise to disengage the spin buckle slot 211 from the spin buckle block 137, the human hand also needs to overcome the obstruction of the blocking slot 1371 to the block 2112, so that the connecting pipe part 21 is elastically concave and deformed to enable the block 2112 to slide off the blocking slot 1371. In other words, by providing the blocking slot 1371, the connection between the water inlet connector 2 and the water purifier body 1 is made more firm and reliable.

[0037] Furthermore, if Fig. 9 Combination Fig.10 As shown, one end of the screw groove 211 forms a notch 2111, and the other end of the screw groove 211 corresponding to the screw groove 211 forms a groove end slope 2113, as shown in FIG. Figure 6 As shown, the head end of the spin block 137 is formed with a block end slope 1373 (the "head end" mentioned here refers to the end that first enters the spin groove 211 during the process of the spin block 137 relatively rotating into the spin groove 211). Fig.11 As shown, the block end slope 1373 and the groove end slope 2113 are adapted to be closely connected, so when the screw-in block 137 is relatively screwed into the screw-in groove 211, the clamping block 2112 can slide onto the screw-in block 137 along the block end slope 1373, and then the clamping block 2112 slides into the blocking clamping groove 1371. After the clamping block 2112 slides into the blocking clamping groove 1371, the groove end slope 2113 and the block end slope 1373 are closely connected to support each other.

[0038] Furthermore, if Figure 6 As shown, the rear end of the spin buckle block 137 is formed with a reverse thrust portion 1372 (the "rear end" is relative to the "head end" mentioned above). Fig. 9 and Fig.10As shown, the water inlet connector 2 is formed with a guide slope 212 for relatively guiding the reverse thrust portion 1372, and the avoidance position 213 is located between the guide slope 212 and the notch 2111. The reverse thrust portion 1372 can slide relatively along the guide slope 212 through the rotation movement of the water inlet connector 2 to move the water inlet connector 2 outward. Specifically, when the water inlet connector 2 is rotated counterclockwise to disengage the screw groove 211 from the screw block 137, the water inlet connector 2 continues to be rotated counterclockwise, and the guide slope 212 will hit the reverse thrust portion 1372, as shown in FIG. Fig.10 As shown, since the guide slope 212 forms an angle with the axis of the connecting pipe portion 21, the reaction force of the reverse thrust portion 1372 on the guide slope 212 has an outward component along the axial direction of the connecting pipe portion 21, so that the reverse thrust portion 1372 climbs relatively along the guide slope 212, resulting in the water inlet connector 2 moving outward and away from the water purifier body 1. In other words, as long as the water inlet connector 2 is rotated counterclockwise after the locking block 3 is unlocked, the water inlet connector 2 can be disengaged and slide outward, making it convenient to disassemble the water inlet connector 2.

[0039] Furthermore, if Figure 6 As shown, the number of the spin buckle blocks 137 is set to two, and the two spin buckle blocks 137 are circumferentially distributed. Specifically, the two spin buckle blocks 137 can be distributed 180° apart. In other words, the spin buckle grooves 211 are also distributed 180° apart, which is beneficial to balance the force on the water inlet connector 2 and to ensure a reliable connection between the water inlet connector 2 and the water purifier body 1.

[0040] like Figure 3 and Figure 4 As shown, tap water enters the supporting pipe portion 22 from the hose 99, flows through the water passage 202 and is then discharged from the connecting pipe portion 21 to the insert pipe portion 132, enters the base 11, fills the water passage cavity 100 and then passes through the filter element assembly 6, and the clean water filtered by the filter element assembly 6 is discharged from the water outlet faucet 5.
