Water purifier with anti-dripping function and use method thereof

Abstract

The present application relates to the technical field of water purifiers, and particularly relates to a water purifier with a drip-proof function and a use method thereof. When a filter core is installed in an integrated water channel mechanism, a small cylindrical protrusion can be in contact with a stop valve opening and closing structure and press down a stop valve piston rod, so that the stop valve opening and closing structure and the stop valve are in an open state. Meanwhile, a filter core water outlet push rod is inserted into the small cylindrical protrusion to open a stop valve in a protrusion in a cylinder. When the filter core is disassembled from the integrated water channel mechanism, the stop valve piston rod loses pressure from the filter core, and the stop valve piston rod is reset under the action of a reset spring, so that the stop valve and the stop valve opening and closing structure return to a closed state. Meanwhile, the stop valve in the protrusion in the cylinder loses the pressure from the filter core water outlet push rod, and the stop valve is closed. Therefore, even if the water inlet is not closed, the phenomenon that a large amount of water drops into the water purifier or onto the ground when the filter core is disassembled is prevented, the automatic water stopping and drip-proof function of the water purifier is improved, and the convenience of disassembling and maintaining the water purifier is improved.

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application, and will be explained in detail below.

[0059] Example 1

[0060] like Figures 1 to 31 As shown, in this embodiment, the front end of the water purifier is provided with a decorative cover 1 that serves both decorative and dustproof functions. A through-type light guide hole 11 is provided at the upper center of the decorative cover 1. After installing a conventional light guide at the light guide hole 11, no wiring is required, allowing the outer side of the decorative cover 1 to synchronously display the lighting effect of the indicator lights on the main control board. The decorative cover 1 is fixed with magnets, offering advantages such as convenient installation and disassembly. Multiple magnet mounting slots 12 are provided on the side of the decorative cover 1, with magnets installed within each slot. To reduce deformation of the decorative cover 1 after injection molding, multiple reinforcing ribs 13 are also provided on its inner side. For ease of opening the decorative cover 1, an arc-shaped handle 14 is provided on the inner side of its lower edge.

[0061] As a specific embodiment of the improvement, the outermost layer of the filter element 2 is the filter barrel 21 and the filter barrel cover 22, which can be connected by conventional threads or welding. The upper part of the filter barrel 21 is a cylindrical filter barrel cylinder 2101, the internal cavity of which is a cylindrical inner cavity 2105 for placing the filter element. The middle part of the lower end surface of the filter barrel cylinder 2101 extends downward coaxially to a large cylindrical protrusion 2102, a medium cylindrical protrusion 2103, and a small cylindrical protrusion 2104, which have diameters decreasing in turn. The upper end surface of the filter barrel cylinder 2101 also extends upward coaxially to an annular connecting bone 2106 for connecting the filter barrel cover 22.

[0062] Further, two connecting clamping positions 2107 for clamping the filter element fixing seat 43 and a positioning clamping point 2108 are arranged radially on the lower part of the outer wall of the large cylindrical protrusion 2102. The two connecting clamping positions 2107 are distributed at 180 degrees. The arrangement of the positioning clamping point 2108 allows the user to not deliberately align when installing the filter element 2. The filter element 2 can be inserted into the filter element installation cylinder 302 and rotated clockwise after the filter element 2 abuts against the upper plane of the filter element fixing seat 43. After the positioning clamping point 2108 automatically coincides with the installation directional clamping hole 4312, the filter element 2 can be quickly clamped on the filter element fixing seat 43 by rotating it once again, thereby improving the installation efficiency of the filter element.

[0063] Further, a plurality of radial cylindrical reinforcing ribs 2111 are arranged at the inner plane where the filter barrel cylinder 2101 and the large cylindrical protrusion 2102 are connected. The cylindrical reinforcing ribs 2111 can increase the strength of the filter barrel 21 and support the accessories inside the filter barrel 21, preventing the accessories from sinking to the bottom plane of the filter barrel cylinder 2101 and thereby hindering the flow of tap water into the filter element.

[0064] Further, a plurality of medium protrusion sealing ring grooves 2109 are arranged at the outer wall of the medium cylindrical protrusion 2103. A filter cover connecting hole 2113 and a water stop valve installation hole 2114 are arranged in the inner cavity plane of the medium cylindrical protrusion 2103 from top to bottom in turn. In order to introduce tap water into the inside of the filter element 2, a plurality of penetrating filter element water inlet holes 2115 are arranged at the bottom plane of the medium cylindrical protrusion 2103, which connect the cylindrical inner cavity 2105 and the external space of the filter element 2,

[0065] Further, a plurality of filter cover connecting hole reinforcing ribs 2116 are radially arranged between the inner wall of the medium cylindrical protrusion 2103 and the outer wall of the filter cover connecting hole 2113.

[0066] Further, the outer wall of the cylindrical small protruding column 2104 is provided with a plurality of small protruding column sealing ring grooves 2110, and the center of the cylindrical small protruding column 2104 is further provided with a penetrating filter core water outlet hole 2117, which is in communication with the water stop valve mounting hole 2114, the filter cover connecting hole 2113 and the cylindrical inner cavity 2105 in sequence. The tap water flowing into the filter core is purified by the filter core 2 and then flows out from the filter core water outlet hole 2117.

[0067] As an improved specific embodiment, the lower end of the filter bucket cover 22 is a cylindrical filter bucket cover body 221, one end of which is closed and the other end is open. A track-shaped filter bucket cover handle 222 extends outward from the plane of the closed end. A connecting groove 223 for connecting the filter bucket 21 is arranged on the side wall of the open end. A plurality of filter bucket cover reinforcing ribs 224 are further arranged in the inner cavity of the filter bucket cover 22.

[0068] As an improved specific embodiment, the filter bucket partition plate 24 is arranged in a hollow cylindrical shape, and the middle hole is a penetrating partition plate middle hole 241. When assembled, the water outlet cover small protruding column 254 on the filter core water outlet cover 25 passes through the partition plate middle hole 241 and is sealingly connected with the inner wall of the partition plate middle hole 241 through the sealing ring at the inner sealing ring groove 255. A water stop valve fixing hole 242 is further arranged between the partition plate middle hole 241 and the inner wall of the filter bucket partition plate 24. Further, a plurality of partition plate sealing ring grooves 243 are arranged on the outer wall of the filter bucket partition plate 24. When assembled, the filter bucket partition plate 24 is sealingly connected with the side wall of the partition plate mounting groove 2112 through the sealing ring on the partition plate sealing ring groove 243. Through the sealing effect of the sealing ring on the partition plate sealing ring groove 243, the sealing ring on the inner sealing ring groove 255 and the water stop valve on the water stop valve fixing hole 242, the water droplets left between the outer wall of the filter core cylindrical body 261 and the inner wall of the filter bucket 21 when the used filter core is disassembled can be effectively prevented from falling to the ground, thereby reducing unnecessary trouble.

[0069] Further, a C-shaped blocking ring 244 extends axially downward from the lower end surface of the filter bucket partition plate 24. The opening of the C-shaped blocking ring 244 is a blocking ring water collecting port 245, which is arranged on the side close to the water stop valve fixing hole 242. The blocking ring water collecting port 245 plays a role of collecting water flow, that is, when the tap water enters the lower part of the filter core from the filter core water inlet hole 2115, it is all collected after encountering the C-shaped blocking ring 244 and then flows out from the blocking ring water collecting port 245. The concentrated water flow is more conducive to flushing away the water stop valve installed on the filter bucket partition plate 24, and finally flows into the cylindrical inner cavity 2105 after passing through the water stop valve.

[0070] As a specific embodiment of the improvement, the large-end of the filter core outlet cover 25 is a cylindrical outlet cover body 251, and a large outlet cover protrusion 252 extends axially outward from one side of the large plane of the outlet cover body 251. A plurality of protrusion reinforcing ribs 253 are also radially provided on the side wall of the large outlet cover protrusion 252. A small outlet cover protrusion 254 extends axially outward from the outer side plane of the large outlet cover protrusion 252. Further, an inner sealing ring groove 255 and an outer sealing ring groove 256 are respectively provided on the outer wall of the small outlet cover protrusion 254 from the inner end to the outer end. The inner cavities of the filter core outlet cover 25, the large outlet cover protrusion 252, and the small outlet cover protrusion 254 are connected to form an outlet cover outlet hole 257. The water purified by the filter core 2 flows out from the outlet cover outlet hole 257.

[0071] Further, an annular outlet cover positioning ring 258 extends inwardly from the inner side of the middle part of the large plane of the filter core outlet cover 25. The positioning ring 258 can position the rod-shaped filter material 27 installed in the filter core outlet cover 25 at the center position of the filter core shell 26, thereby improving the reliability of the filter core during operation. An outlet cover connecting thread 259 is also provided on the inner wall of the filter core outlet cover 25 to connect with the thread at the end of the filter core shell 26.

[0073] As a specific embodiment of the improvement, the rod-shaped filter material 27 is generally a hollow rod-shaped body composed of one or more filtering materials and processed by conventional processes. The outer part is a filter material body 271, and a filter material inner hole 272 is provided in the middle of the filter material body 271. The impurities in the water flowing from the outer wall to the inner wall of the filter material body 271 are adsorbed or intercepted by the filter material body 271, thereby purifying the tap water. The purified tap water collects in the filter material inner hole 272 and then flows out from the outlet cover outlet hole 257 of the filter core outlet cover 25.

[0074] As a specific embodiment of the improvement, the filter core plug 28 is designed like a flange and made of ordinary plastic to seal the open end of the rod-shaped filter material 27. A plug recess 281 is designed in the middle of the filter core plug 28.

[0075] As an embodiment of the improvement, the filter core water inlet cover 29 is in a cylindrical shape, and a water inlet cover main plane 291 is arranged at one end of the filter core water inlet cover 29.

Directly below the 7-shaped upper edge 292, a plurality of penetrating fan-shaped water inlet grooves 293 and a plurality of upper edge reinforcing ribs 294 are arranged. In operation, tap water enters the gap between the inner wall of the filter core shell 26 and the outer wall of the rod-shaped filter material 27 through the fan-shaped water inlet grooves 293, is filtered through the rod-shaped filter material 27, is collected at the filter material inner hole 272 in the middle of the rod-shaped filter material 27, and finally flows out from the water outlet hole 257 of the filter core water outlet cover 25. Further, an intermediate boss 295 is arranged axially inwardly on the inner side of the water inlet cover main plane 291. During assembly, the intermediate boss 295 is inserted into the boss recess 281 in the middle of the filter core plug 28, so as to ensure that the rod-shaped filter material 27 is installed in the middle position of the filter core, thereby improving the stability of the filter core during operation.

[0082] Further, a plurality of fixed seat mounting columns 4107 and anti-reverse columns 4108 are arranged around the periphery of each level of water inlet and outlet holes on the upper plane of the integrated waterway plate 41. The anti-reverse columns 4108 will hinder the insertion of the filter core fixed seat 43 when inserted into each level of water inlet and outlet holes in reverse, thereby preventing the filter core fixed seat 43 from being installed in reverse. A plurality of support connection columns 4109 for connecting the main machine support 3 are arranged near the edges of the upper plane of the integrated waterway plate 41. The distribution of the support connection columns 4109 corresponds to the support fixing holes 312 on the main machine support 3.

[0083] Further, a waterway plate water inlet 4110 for installing the quick connector 44 for inputting tap water and a waterway plate water outlet 4111 for installing the quick connector 44 for outputting purified water are arranged at the left end side of the integrated waterway plate 41. In order to reduce the connection ports of the water purifier and facilitate the assembly and injection molding of the water purifier, a plurality of water channel plugging ports 4112 for quick plugging are arranged at the water inlet and outlet ports.

[0084] Further, in order to realize the flow monitoring function of the integrated waterway mechanism 4, a Hall detector mounting groove 4113 is arranged beside one end of the first water conveying channel 4115. The Hall detector 46 of the flow meter is fixed by screws at the Hall detector mounting groove 4113. The flow meter rotor 45 is installed at the flow meter rotor mounting groove 4120 in the port of the first water conveying channel 4115, and the positions of the flow meter rotor 45 and the Hall detector 46 are matched.

[0085] Further, a plurality of rear cover connection columns 4114 for connecting the main machine rear cover 6 are arranged on the bottom surface of the integrated waterway plate 41, and the distribution of the rear cover connection columns 4114 matches the rear cover screw holes 61 on the main machine rear cover 6. A set of magnetizer mounting grooves 4119 is arranged at the middle position of the bottom surface of the integrated waterway plate 41. The water quality magnetizer 48 for activating water quality is installed at the magnetizer mounting groove 4119, and the magnetizer mounting groove 4119 is arranged on the left and right sides of the last level of water conveying channels.

[0086] Further, the integrated waterway plate 41 is internally provided with a first water delivery channel 4115, a second water delivery channel 4116, a third water delivery channel 4117 and a third water delivery channel 4118. The first water delivery channel 4115 is composed of a first horizontal channel 4115A, a second horizontal channel 4115B and a vertical channel 4115C. The first horizontal channel 4115A is located in the lower layer of the integrated waterway plate 41, the second horizontal channel 4115B is located in the upper layer of the integrated waterway plate 41, and the vertical channel 4115C is located in the middle layer of the integrated waterway plate 41. The first horizontal channel 4115A and the second horizontal channel 4115B are horizontally distributed, and the vertical channel 4115C is vertically distributed. The vertical channel 4115C connects the end of the first horizontal channel 4115A in the upper layer and the front end of the second horizontal channel 4115B in the lower layer to form a complete first water delivery channel 4115. The first water delivery channel 4115 is used to deliver tap water to the water inlet of the first filter element. The second water delivery channel 4116 is used to deliver water purified by the first filter element to the water inlet of the second filter element. The third water delivery channel 4117 is used to deliver water purified by the second filter element to the water inlet of the third filter element. Similarly, the third water delivery channel 4118 is used to deliver water purified by the third filter element to the water outlet 4111 of the waterway plate, and then the water is supplied to the user through the control of the water outlet faucet. Of course, the number of filter element levels and water delivery channels can be set according to actual needs.

[0087] Further, in order to ensure good sealing of each water delivery channel, after the integrated waterway plate 41 is injection molded, the water channel sealing port 4112 needs to be sealed by a plug. The sealing port 4112 of the water channel is provided with a quick-to-install and welding-free plug 42 to prevent water leakage.

[0088] As an improved specific embodiment, the welding-free plug 42 is designed as a hollow cylinder similar to a T-shaped and one-end-closed cylinder. The large end of the plug body 421 is provided with a ring of plug claws 422 radially on the middle part of the side wall. In order to facilitate installation and have good firmness, the plug claws 422 are made of stainless steel sheets or other metal sheets with good hardness and elasticity with a thickness of less than 1 mm and are embedded on the side wall of the plug body 421 by injection molding process. The small end of the plug body 421 is provided with a plug sealing ring 423. When assembling, the welding-free plug 42 is only pressed into the water channel sealing port 4112, and the plug claws 422 are tightly clamped on the inner wall of the water channel sealing port 4112. Then, the water channel sealing port 4112 is sealed by the sealing action of the plug sealing ring 423, which can avoid the trouble of welding the common plug.

[0089] As a specific embodiment of the improvement, the filter core fixing seat 43 is a component for fixing the filter core 2 and connecting the water inlet and outlet interfaces of the filter core 2. The filter core fixing seat 43 is in the shape of a cylinder as a whole. The upper part of the filter core fixing seat 43 is a fixing seat body 4301. Two fan-shaped fixing seat clamping positions 4302 for clamping the filter core 2 are arranged on the inner wall of the uppermost end of the fixing seat body 4301. The two fixing seat clamping positions 4302 are distributed at an angle of 180 degrees on the inner wall of the fixing seat body 4301. A filter core clamping strip 4303 and a filter core stop baffle 4304 are axially arranged on the inner wall below one of the fixing seat clamping positions 4302. Further, a clamping position guide inclined surface 4305 extending downward and obliquely is arranged at the end of each fan-shaped fixing seat clamping position 4302 in the clockwise direction. The clamping position guide inclined surface 4305 plays a guiding role when the filter core 2 is disassembled.

[0090] Further, the filter core 2 in the embodiment can be disassembled in a rotating manner. When the filter core 2 is inserted into the filter core mounting cylinder 302 of the main machine support 3 and rotated clockwise, the filter core 2 will slide along the clamping position guide inclined surface 4305 until the front end surface of one of the connecting clamping positions 2107 on the filter core 2 is just against the filter core stop baffle 4304. At this time, the upper surface of the connecting clamping position 2107 is just clamped at the lower surface of the fixing seat clamping position 4302. Meanwhile, the groove on the outer surface of the connecting clamping position 2107 close to the filter core clamping strip 4303 on the filter core 2 is also just clamped at the filter core clamping strip 4303. Thus, the fixation of the filter core 2 is realized. Conversely, when the filter core 2 is rotated counterclockwise, the filter core 2 is first disengaged from the filter core clamping strip 4303, then slides upward along the clamping position guide inclined surface 4305, and finally is completely disengaged from the fixing seat clamping position 4302. Thus, the disassembly of the filter core 2 is realized.

[0091] Further, a fixing seat large ring 4306 and a fixing seat small ring 4308 are axially arranged upward at the middle position of the inner wall of the filter core fixing seat 43. The fixing seat large ring 4306 is higher than the fixing seat small ring 4308. The fixing seat large ring 4306 is used for sleeving the cylindrical middle protruding column 2103 on the filter core 2. The fixing seat small ring 4308 is used for sleeving the cylindrical small protruding column 2104 on the filter core 2.

[0092] Further, a water stop valve push rod hole 4307 is arranged between the inner wall of the fixing seat large ring 4306 and the outer wall of the fixing seat small ring 4308 and at the same height as the fixing seat small ring 4308. A opening and closing structure mounting hole 4318 is axially extended downward below the water stop valve push rod hole 4307. The water stop valve push rod hole 4307 is connected with the opening and closing structure mounting hole 4318 and the inner cavity of the fixing seat large ring 4306 respectively. The water stop valve opening and closing structure 49 is mounted in the opening and closing structure mounting hole 4318 during assembly.

[0093] Further, a filter core water outlet push rod 4309 is axially arranged at the center of the plane in the filter core fixing seat 43. When the filter core 2 is installed in place, the filter core water outlet push rod 4309 pushes the piston of the stop valve 23 installed at the stop valve installation hole 2114, at which time the purified water stored in the filter material inner hole 272 in the middle of the rod-shaped filter material 27 can flow out of the filter core 2 through the stop valve 23. When the filter core 2 is removed from the filter core fixing seat 43, the piston of the stop valve 23 is closed due to the lack of the pushing force of the filter core water outlet push rod 4309, so that the purified water remaining in the filter material inner hole 272 in the middle of the filter core will not drip to the ground, thereby reducing unnecessary trouble. Further, a fixing seat water outlet hole 4310 is arranged on the plane in the filter core fixing seat 43 corresponding to the axis of the fixing seat water outlet column hole 4317. The fixing seat water outlet hole 4310 is in communication with the fixing seat water outlet column hole 4317.

[0094] Further, two filter core supporting blocks 4311 are arranged on the inner wall of the filter core fixing seat 43 and match the rotation track of the filter core 2. The two filter core supporting blocks 4311 are distributed at an angle of 180 degrees. The filter core supporting blocks 4311 can support the lower plane of the connection clamping site 2107 on the filter core 2 when the filter core 2 is rotated to be disassembled or assembled, so that the filter core 2 is more smooth to disassemble and assemble.

[0095] Further, an installation directional socket 4312 is arranged at the middle position of the one fixing seat clamping site 4302 away from the filter core stop baffle 4304. When the filter core 2 is installed, it only needs to be inserted into the bottom of the filter core installation cylinder 302 and rotated to the alignment clamping site 2108 to coincide with the installation directional socket 4312, and then the filter core 2 is rotated to slide along the clamping site guide slope 4305 to abut against the filter core stop baffle 4304, so that the quick and reliable installation of the filter core 2 is realized. The installation directional socket 4312 makes the user not need to deliberately align when installing the filter core 2, so that the installation of the filter core 2 becomes more convenient and fast.

[0096] Further, a plurality of fixing seat screw holes 4313 are arranged on the bottom plane of the filter core fixing seat 43. The distribution of the fixing seat screw holes 4313 matches the fixing seat installation column 4107 on the integrated waterway board 41. The filter core fixing seat 43 can be fixed to the fixing seat installation column 4107 through screws.

[0097] Further, a fixed seat water inlet column 4314 is coaxially arranged below the opening and closing structure mounting hole 4318, the inner cavity of the fixed seat water inlet column 4314 is provided with a fixed seat water inlet column hole 4315, and the fixed seat water inlet column hole 4315 is in communication with the opening and closing structure mounting hole 4318. During assembly, a stop valve 23 is also mounted at the fixed seat water inlet column hole 4315. When the stop valve 23 at this position is opened, water can flow into the filter core 2. Conversely, when the stop valve 23 at this position is closed, water flow into the filter core 2 is prevented.

[0098] Further, a fixed seat water outlet column 4316 is axially arranged below the fixed seat water outlet hole 4310, the inner cavity of the fixed seat water outlet column 4316 is provided with a fixed seat water outlet column hole 4317, and the fixed seat water outlet column hole 4317 is in communication with the fixed seat water outlet hole 4310. During assembly, a stop valve 23 is mounted at the fixed seat water outlet column hole 4317. When the stop valve 23 at this position is opened, purified water stored in the filter material inner hole 272 inside the filter core 2 can flow out of the filter core 2. Conversely, when the stop valve 23 at this position is closed, the purified water in the filter material inner hole 272 inside the filter core 2 is prevented from flowing out of the filter core 2.

[0099] As an improved specific embodiment, the magnetizer cover 47 is mounted above the magnetizer mounting groove 4119 on the integrated waterway board 41 to fix the water quality magnetizer 48.

[0100] As an improved specific embodiment, the stop valve opening and closing structure 49 is used to control the opening or closing of the stop valve 23 mounted in the fixed seat water inlet column hole 4315. The lower part of the stop valve opening and closing structure 49 is a flange-shaped opening and closing structure base 491, the middle part is a return spring 492, and the upper part is a stop valve piston rod 493. During assembly, the bottom of the opening and closing structure base 491 abuts against the top flat surface of the stop valve 23, and the lower end of the stop valve piston rod 493 passes through the center hole of the return spring 492 and the opening and closing structure base 491. After the filter core 2 is installed in place, the lower flat surface of the filter core cylinder small protruding column 2104 presses the stop valve piston rod 493 downward, and then the lower end of the stop valve piston rod 493 pushes the piston of the stop valve 23 away, so that water can flow out of the integrated waterway mechanism 4 and enter the filter core 2 after passing through the stop valve 23. Conversely, when the filter core 2 is removed, the stop valve piston rod 493 moves upward and resets under the elastic force of the return spring 492, so that the piston of the stop valve 23 loses the pushing force and returns to the closed state. At this time, water cannot flow out of the integrated waterway mechanism 4, thereby preventing water from dripping into the water purifier or onto the ground when the filter core 2 is disassembled, and improving the anti-dripping function when the water purifier is disassembled.

[0101] As an improved specific embodiment, the host shell 5 is arranged outside the water purifier, and a plurality of shell support bones 51 for supporting the host support 3 and the host rear cover 6 are arranged on the inner wall of the periphery of the host shell 5. The front end of each shell support bone 51 is provided with a front end clamping groove 52 for clamping the host support 3, and the rear end is provided with a rear end clamping groove 53 for clamping the host rear cover 6. A plurality of shell support feet 54 for supporting the entire water purifier are arranged at the lower surface of the host shell 5.

[0102] As an improved specific embodiment, the host rear cover 6 is arranged at the rear end of the water purifier, and a plurality of rear cover screw holes 61 are arranged on the plane of the host rear cover 6. The distribution of the rear cover screw holes 61 matches the distribution of the rear cover connecting columns 4114 on the integrated waterway board 41. Further, two penetrating quick plug extension holes 62 and one penetrating indicator lamp connector mounting hole 63 are arranged at the upper end of the host rear cover 6. The distribution of the quick plug extension holes 62 matches the positions of the quick plugs 44 on the integrated waterway mechanism 4.

[0103] Further, a plurality of bottom cover reinforcing ribs 64 are arranged at the inner plane of the host rear cover 6. In addition to enhancing the strength of the host rear cover 6, the outermost reinforcing ribs on the inner plane of the host rear cover 6 can also serve as a clamping position connected with the host shell 5. When the host rear cover 6 is assembled onto the host shell 5, the outermost bottom cover reinforcing ribs 64 of the host rear cover 6 are clamped tightly at the rear end clamping groove 53 of the host shell 5, thereby ensuring that the host shell 5 will not deform outward, increasing the reliability and firmness of the water purifier.
