[0032] With the improvement of living standards, people's requirements for water quality are getting higher and higher, and the installation rate of household water purification equipment is also getting higher and higher, especially for kitchen water purification equipment, limited by the height of the cabinet under the sink, the volume of the water purification equipment is required to be as small as possible, especially the height size of the water purification equipment, the water purification equipment often cannot be installed into the cabinet because of the size is too high. And the current kitchen water purification equipment, the noise generated by the water pump in the working process is large, which leads to poor user experience.

[0033] In view of this, the present application provides a water purification equipment. It should be noted that the water purification equipment can be a water purifier, a water purifier, a soft water integrated machine, and a water purification and heating integrated machine, and other products with water purification function.

[0034] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the water purification equipment 10 includes a shell 100, a mounting frame 200, a filter element module 300 and a water pump 400, the shell 100 is formed with a containing cavity 100a, the shell 100 includes a base 110, a middle shell 120 and a top cover 130, and the containing cavity 100a is formed by the base 110, the middle shell 120 and the top cover 130. The containing cavity 100a is used to accommodate other components of the water purification equipment 10, and the shell 100 prevents the other components in the containing cavity 100a from being disturbed by the outside. Among them, the lower end of the middle shell 120 and the base 110 are connected by clamping, the upper end of the middle shell 120 and the top cover 130 are detachably connected, and the upper end of the middle shell 120 is also fixedly installed with the mounting frame 200. For the connection mode of the mounting frame 200 in the containing cavity 100a and other structures of the water purification equipment 10, please refer to the description later.

[0035] Further, the middle shell 120 comprises a front shell 121, a rear shell 122, and a first side plate 123 and a second side plate 124 arranged oppositely, the front shell 121 can be understood as the shell 100 facing the user side when the water purification equipment 10 is used, the rear shell 122 is the back shell opposite to the front shell 121, the two side edges of the first side plate 123 and the second side plate 124 are connected with the front shell 121 and the back shell respectively, and the bottom edges of the first side plate 123 and the second side plate 124 are connected with the base 110. The above connection mode can be clamping or connected together by bolts, and no specific limitation is made here.

[0036] Further, the mounting bracket 200 is located in the accommodating cavity 100a, and the mounting bracket 200 is connected with the shell 100, wherein the connection mode can be buckle connection, screw connection or riveting, and no specific limitation is made here. The mounting bracket 200 is connected with the base 110 together, and in the embodiment, the bottom of the mounting bracket 200 is provided with a fixing part 240, and the fixing part 240 is fixedly connected with the base 110 by bolts to fix the position of the mounting bracket 200 in the accommodating cavity 100a.

[0037] The related prior art water pump is installed on the base, and in this case, on the one hand, the water pump installed on the base occupies a large bottom space, and it is difficult to reduce the size (length, width and height) of the water purification equipment, on the other hand, the water pump will vibrate when running, and directly installing the water pump on the base will cause strong vibration of the base, and further transmit the vibration to the middle shell and the top cover, thereby making the shell have a large noise, therefore, in the embodiment, the water pump 400 is fixedly installed on the positioning seat 230 of the mounting bracket 200, which can slow down the transmission of vibration of the water pump 400 when running, thereby realizing noise reduction, and on the other hand, it can also reasonably utilize the space of the accommodating cavity 100a in the shell 100, reduce the structural arrangement on the base 110 of the water purification equipment 10, and thereby reduce the size of the water purification equipment 10. In order to ensure the stability of the water pump 400 after being installed on the mounting bracket 200, the water pump 400 and the positioning seat 230 are fixedly connected by screwing. Further, in order to further reduce the transmission of vibration of the water pump 400 during operation, a buffer pad can be arranged between the water pump 400 and the positioning seat 230 to further reduce the transmission of vibration of the water pump 400, thereby reducing the noise.

[0038] For the purpose of reducing the size of the water purifying device 10, the related prior art places the water pump below the first filter element and the second filter element (i.e. the water pump is installed on the base), in order to further reduce the height of the water purifying device 10, so as to adapt the water purifying device 10 to the space in the kitchen cabinet (the space between the bottom of the water tank and the lower panel of the cabinet), the present application moves the water pump 400 in the water purifying device 10 from below the filter element module 300 to be arranged in the axial direction of the first filter element 310 and spaced from the first filter element 310. It should be noted that the water pump 400 is placed in the upper space of the main waterway plate 510, so as to reduce the height of the original water purifying device without increasing the length of the original water purifying device, and reduce the height of the original water purifying device by 30mm to 50mm, which accounts for about 15% of the height of the original water purifying device.

[0039] Please refer to Figure 1 and Figure 2 Further, the axial length of the water pump 400 is greater than the radial length of the water pump 400, and the axial direction of the water pump 400 is consistent with the height direction of the water purifying device 10. It should be noted that the water pump 400 is arranged in a substantially cylindrical shape, and the axial length of the water pump 400 is greater than the radial length of the water pump 400. Considering that if the water pump 400 is placed horizontally in the receiving cavity 100a (i.e. the axial direction of the water pump 400 is consistent with the length direction of the water purifying device 10), and considering that the first filter element 310 is also placed horizontally, the water pump 400 will increase the length of the water purifying device 10, which does not meet the miniaturization design of the water purifying device 10. Therefore, the water pump 400 is placed vertically in the receiving cavity 100a (i.e. the axial direction of the water pump 400 is consistent with the height direction of the water purifying device 10), so that the water pump 400 can be placed in the axial direction of the first filter element 310 without increasing the length of the original water purifying device, and the use space in the receiving cavity 100a can be maximized, which meets the miniaturization design of the water purifying device 10.

[0040] Please refer to Figure 1 and Figure 2 In an embodiment, the filter element module 300 includes a first filter element 310 and a second filter element 320, the first filter element 310 and the second filter element 320 are installed in the installation cavity of the installation frame 200, the first filter element 310 and the second filter element 320 are arranged horizontally in the receiving cavity 100a, and the first filter element 310 and the second filter element 320 are arranged vertically in the receiving cavity 100a. By arranging in this way, the height of the water purifying device 10 can be reduced, and the vertically arranged first filter element 310 and second filter element 320 are compact in structure, which can further reduce the size of the water purifying device 10.

[0041] Specifically, the filter core module 300 contains two filter core structures, namely a first filter core 310 and a second filter core 320, which are integrated in two filter bottle containers. One of the first filter core 310 and the second filter core 320 is a reverse osmosis filter core, and the other is a composite filter core (a pre-filter and / or a post-filter are integrated in the same filter bottle); it can be that the first filter core 310 is a reverse osmosis filter core and the second filter core 320 is a composite filter core, or the first filter core 310 is a composite filter core and the second filter core 320 is a reverse osmosis filter core, all of which are optional embodiments of the present application. It should be noted that the raw water entering the water purification equipment 10 will first be filtered by the pre-filter, which will adsorb larger particles of impurities in the water. The water filtered by the pre-filter is then filtered by the RO membrane of the reverse osmosis filter core to remove most of the salt ions in the water. The filtered water filtered by the reverse osmosis filter core is filtered by the post-filter and then flows into the user end through the faucet.

[0042] It should be noted that the first filter core 310 and the second filter core 320 are approximately cylindrical in shape, and the axial length of the first filter core 310 is greater than the radial length of the first filter core 310. Similarly, the axial length of the second filter core 320 is also greater than the radial length of the second filter core 320. Therefore, the first filter core 310 and the second filter core 320 are horizontally arranged in the receiving cavity 100a, which has the advantage of reducing the height of the water purification equipment 10 compared to vertically placing the first filter core 310 and the second filter core 320 in the receiving cavity 100a. Furthermore, the first filter core 310 and the second filter core 320 are horizontally arranged in the receiving cavity 100a, i.e., the axial direction of the first filter core 310 and the second filter core 320 is consistent with the horizontal direction.

[0043] By horizontally installing the first filter core 310 and the second filter core 320 in the receiving cavity 100a, the water pump 400 originally placed below the first filter core 310 and the second filter core 320 is transferred to one side of the axial direction of the first filter core 310, thereby reducing the height of the water purification equipment 10, which is beneficial to adapt to the space in the cabinet with a smaller height space and facilitate the installation of the household water purification equipment 10.

[0044] Please refer to Figure 2 and Figure 3In an embodiment, the top cover 130 and the middle shell 120 are connected by clamping. The clamping connection is convenient to operate, and can ensure the consistency of the appearance of the water purification equipment 10. Meanwhile, the separate fixing type clamping buckle is used for connection, so that the fixing and the limiting are separated, the gap is relatively large when the assembly is contacted, and the gap between the top cover 130 and the middle shell 120 becomes nearly no gap when the assembly is in place, so that the connection and fixing of the top cover 130 and the middle shell 120 are reliable, and the top cover 130 and the middle shell 120 will not be loose, and have strong rigidity, so that the noise caused by the vibration of the water pump 400 is reduced. In the embodiment, the top cover 130 is provided with a clamping portion 131, and the upper end of the middle shell 120 is provided with a clamping opening 125a which is clamped and matched with the clamping portion 131.

[0045] Further, the upper end of the middle shell 120 is provided with a clamping plate 125, the clamping opening 125a is arranged in the clamping plate 125, the clamping portion 131 includes a first clamping hook 131a, and the first clamping hook 131a is clamped and matched with the first clamping opening 125a1. The clamping portion 131 further includes a second clamping hook 131b, the second clamping hook 131b is arranged in the first clamping hook 131a, and the clamping opening 125a further includes a second clamping opening 125a2, the second clamping hook 131b is clamped and matched with the second clamping opening 125a2. The clamping portion 131 is arranged to include the first clamping hook 131a and the second clamping hook 131b, and the two clamping hooks are arranged at intervals, so that the clamping effect of the top cover 130 and the middle shell 120 can be further improved.

[0046] It should be noted that the number of the clamping portion 131 is at least two. When the number of the clamping portion 131 is two, the two clamping portions 131 are arranged at the upper end of the first side plate 123 and the second side plate 124, so as to realize the clamping connection of the top cover 130 and the first side plate 123 and the second side plate 124. When the number of the clamping portion 131 is three, the three clamping portions 131 are arranged at the upper end of the first side plate 123, the second side plate 124, the front shell 121 or the rear shell 122, so as to realize the clamping connection of the top cover 130 and the first side plate 123, the second side plate 124, the front shell 121 or the rear shell 122. When the number of the clamping portion 131 is four, the four clamping portions 131 are arranged at the upper end of the first side plate 123, the second side plate 124, the front shell 121 and the rear shell 122, so as to realize the clamping connection of the top cover 130 and the first side plate 123, the second side plate 124, the front shell 121 and the rear shell 122.

[0047] Please refer to Figure 3, it is worth mentioning that the hook portions of the first and second hooks 131a and 131b are opposite to each other. In this way, when the first and second hooks 131a and 131b are respectively clamped with the first and second clamping openings 125a1 and 125a2, the force directions of the first and second hooks 131a and 131b are different, which can further improve the stability of the clamping of the top cover 130 and the middle shell 120, prevent the separation of the top cover 130 and the middle shell 120, and make the connection of the top cover 130 and the middle shell 120 reliable and not loose, and have strong rigidity, thereby reducing the noise caused by the vibration of the water pump 400. Preferably, the hook portions of the first and second hooks 131a and 131b are opposite to each other.

[0048] Please refer to Figure 3 In an embodiment, a limiting opening 125b is further arranged between the first and second clamping openings 125a1 and 125a2, and a limiting column 132 is arranged on the top cover 130 and limitedly matched with the limiting opening 125b. When the top cover 130 and the middle shell 120 are clamped and connected, the limiting column 132 and the limiting opening 125b are limitedly matched, thereby limiting the top cover 130, and avoiding the shaking of the top cover 130 in the horizontal direction after being clamped with the middle shell 120.

[0049] In an embodiment, the distance between the outer wall surface of the water pump 400 and the middle shell 120 is 8-12 mm. Specifically, the distance between the outer wall surface of the water pump 400 and the middle shell 120 can be understood as the shortest distance between the outer wall surface of the water pump 400 and the middle shell 120. Considering that the shape of the water pump 400 is irregular, the outer wall surface of the water pump 400 can also be selected as the outer wall surface with the shortest distance to the middle shell 120. It is found through hand plate experiment test that when the distance between the outer wall surface of the water pump 400 and the middle shell 120 is set to be 8-12 mm, the noise generated is the lowest, and at this time, the sound insulation effect of the water purification equipment 10 is the best. Compared with the almost same products placed by the water pump 400, the noise is reduced by about 2 decibels. Alternatively, the distance between the outer wall surface of the water pump 400 and the middle shell 120 is 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm. Preferably, the distance between the outer wall surface of the water pump 400 and the middle shell 120 is about 10 mm. It should be noted that the above values are estimated values, and considering the errors existing in the production and assembly process of the water purification equipment 10, ±0.2 mm of the above values are within the range of the above values.

[0050] Further, since the water pump 400 is installed on the positioning seat 230 of the mounting frame 200, and the positioning seat 230 is arranged at the rear end of the mounting cylinder 220, the distance between the outer wall surface of the water pump 400 and the middle shell 120 is 8-12 mm, which refers to the distance between the outer wall surface of the water pump 400 and the rear shell 122.

[0051] Further, the distance between the outer wall surface of the water pump 400 and the top cover 130 is 8-12 mm. Specifically, the distance between the outer wall surface of the water pump 400 and the top cover 130 can be understood as the shortest distance between the outer wall surface of the water pump 400 and the top cover 130. Considering that the shape of the water pump 400 is irregular, the outer wall surface of the water pump 400 can also be selected at the position where the distance to the top cover 130 is the shortest. It is found through hand plate experiment test that when the distance between the outer wall surface of the water pump 400 and the top cover 130 is set to be 8-12 mm, the noise generated is the lowest, and at this time, the sound insulation effect of the water purification equipment 10 is the best. Compared with the products with almost the same placement of the water pump 400, the noise is reduced by about 2 decibels; alternatively, the distance between the outer wall surface of the water pump 400 and the top cover 130 is 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm, and preferably, the distance between the outer wall surface of the water pump 400 and the top cover 130 is about 10 mm. It should be noted that the above values are estimated values, and considering the errors existing in the production and assembly process of the water purification equipment 10, ±0.2 mm of the above values are within the range of the above values.

[0052] In combination with the above two embodiments, when the distance between the outer wall surface of the water pump 400 and the rear shell 122 and the distance between the outer wall surface of the water pump 400 and the top cover 130 are both about 10 mm, the noise generated when the water pump 400 operates is the lowest, and at this time, the sound insulation effect of the water purification equipment 10 is the best.

[0053] In an embodiment, the water purification equipment 10 further comprises an elastic member (not shown in the figure) arranged between the water pump 400 and the top cover 130 and / or the rear shell 122. Specifically, the elastic member can be arranged between the water pump 400 and the top cover 130, or arranged between the water pump 400 and the rear shell 122, or arranged between the water pump 400 and the top cover 130 and between the water pump 400. The elastic member can be sound-absorbing foam, elastic silica gel or other flexible materials, so as to slow down the vibration generated when the water pump 400 operates and / or reduce the transmission of the noise generated when the water pump 400 operates, thereby further reducing the noise of the water purification equipment 10 when working.

[0054] Please refer to Figures 4 to 6In an embodiment, the mounting frame 200 comprises a mounting plate 210 and a mounting cylinder 220 connected with the mounting plate 210, the cylinder opening of the mounting cylinder 220 is formed on the mounting plate 210, and the inside of the mounting cylinder 220 forms the mounting cavity. Specifically, the mounting plate 210 of the mounting frame 200 is connected with the front shell 121, and the connection mode can be clamping or screwing or other connection modes. In this embodiment, the front shell 121 and the mounting plate 210 of the mounting frame 200 are connected together in a clamping manner, and the connection mode is simple and easy to operate. The inside of the mounting cylinder 220 forms a mounting cavity, and the shape of the mounting cavity is matched with the shape of the first filter element 310 and / or the second filter element 320, so that the first filter element 310 and / or the second filter element 320 can be better installed into the mounting cavity. The cylinder opening of the mounting cylinder 220 is formed on the mounting plate 210, and the first filter element 310 and / or the second filter element 320 are installed into the mounting cavity through the mounting opening. Correspondingly, an opening corresponding to the mounting opening is formed on the front shell 121, so that the user can directly disassemble the filter element from the front shell 121 of the water purification equipment 10 when disassembling or installing the filter element, which is convenient and fast.

[0055] Further, the mounting cylinder 220 has a front end close to the cylinder opening and a rear end away from the cylinder opening, and the positioning seat 230 is connected with the rear end of the mounting cylinder 220. In this way, the position of the water pump 400 is limited on the rear side of the mounting cylinder 220, the structural arrangement on the base 110 of the original water purification equipment is reduced, the height of the original water purification equipment is reduced under the premise of almost not increasing the length of the original water purification equipment, and the height of the original water purification equipment is reduced by 30mm to 50mm, and the reduced height accounts for about 15% of the height of the original water purification equipment.

[0056] Please refer to Figure 4 and Figure 5 In an embodiment, the positioning seat 230 comprises a plurality of positioning protrusions 231, which are arranged on the outer wall surface of the cylinder bottom of the mounting cylinder 220, and are used for fixedly connecting with the water pump 400. Specifically, the plurality of positioning protrusions 231 are provided with through holes or screw holes, so that the water pump 400 is screwed on the plurality of positioning protrusions 231. The plurality of positioning protrusions 231 have the function of positioning, which is used for positioning the position of the water pump 400 installed on the mounting frame 200, so as to further ensure that the distance between the outer wall surface of the water pump 400 and the middle shell 120 and / or the top cover 130 is 8mm-12mm after the water pump 400 is installed on the positioning seat 230, so as to realize noise reduction.

[0057] Further, the lower side of the positioning protrusion 231 is provided with a limiting rib 232 which protrudes from the surface of the positioning protrusion 231 in the axial direction of the mounting cylinder 220. Considering that the water pump 400 is vertically mounted on the positioning seat 230, the provision of the limiting rib 232 can ensure that the water pump 400 will not shake down when it encounters strong vibration during operation after being mounted on the positioning seat. The limiting rib 232 is provided in a plate shape, and the number of limiting ribs 232 can be multiple to further improve the limiting effect of the limiting rib 232 on the water pump 400. At the same time, since the limiting rib 232 is arranged on the lower side of the positioning protrusion 231 and protrudes from the surface of the positioning protrusion 231 in the axial direction of the mounting cylinder 220, the limiting rib 232 also has a positioning function. When the water pump 400 is connected with the positioning protrusion 231, the installation position of the water pump 400 and the positioning protrusion 231 can be positioned by the limiting rib 232, so that subsequent screwing work can be carried out, and the installation efficiency of the water pump 400 is further improved.

[0058] Referring to Figure 4 and Figure 5 On the basis of the previous embodiment, the limiting rib 232 can also be arranged on the left and right sides and / or the upper side of the positioning protrusion 231 to further improve the limiting effect and positioning effect of the limiting rib 232 on the water pump 400.

[0059] Referring to Figure 4 In an embodiment, the mounting cylinder 220 includes a first mounting cylinder 221 and a second mounting cylinder 222 arranged in the up-down direction, the first filter element 310 is arranged in the first mounting cylinder 221, and the second filter element 320 is arranged in the second mounting cylinder 222. Arranging the first filter element 310 and the second filter element 320 in the first mounting cylinder 221 and the second mounting cylinder 222 respectively prevents water from flowing or leaking.

[0060] Further, the first mounting cylinder 221 is located above the second mounting cylinder 222, and the positioning seat 230 is arranged at the rear end of the first mounting cylinder 221. That is, the positioning seat 230 is arranged on the upper part in the containing cavity 100a to reduce the space position of the lower part in the containing cavity 100a, and to provide installation space for the waterway plate module 500, the electromagnetic valve and the like in the water purification equipment 10.

[0061] Referring to Figures 3 to 5In an embodiment, the positioning seat 230 is provided with first connecting portions 250 on opposite sides thereof, and the first connecting portions 250 are provided with first connecting sockets 251 at one end close to the top cover 130, and the top cover 130 is provided with first connecting hooks 133 for engaging with the first connecting sockets 251. Specifically, the first connecting portions 250 are provided on opposite sides of the positioning seat 230, i.e. the first connecting portions 250 are provided at the rear end of the mounting cylinder 220, and the first connecting portions 250 are integrally formed with the mounting frame 200. The top cover 130 and the first connecting portions 250 are connected by the first connecting hooks 133 and the first connecting sockets 251, so as to fix the mounting frame 200 by the top cover 130, further improve the stability of the mounting frame 200 installed in the accommodating cavity 100a, and the top cover 130 and the mounting frame 200 are integrated by the engagement connection, have strong rigidity, and further reduce the noise caused by the vibration of the water pump 400.

[0062] Please refer to Figures 3 to 6 Further, the mounting cylinder 220 is provided with second connecting portions 260 at the front end thereof, and the second connecting portions 260 are provided with second connecting sockets 261 at one end close to the top cover 130, and the top cover 130 is provided with second connecting hooks 134 for engaging with the second connecting sockets 261. The two first connecting portions 250 and the two second connecting portions 260 are provided on opposite sides of the mounting cylinder 220, and the two first connecting hooks 133 and the two second connecting hooks 134 on opposite sides of the top cover 130 are engaged with the first connecting portions 250 and the second connecting portions 260, so as to further improve the stability of the mounting frame 200 installed in the accommodating cavity 100a, and the top cover 130 and the mounting frame 200 are integrated by the engagement connection, have strong rigidity, and further reduce the noise caused by the vibration of the water pump 400.

[0063] Please refer to Figure 4In an embodiment, the rear ends of the first mounting cylinder 221 and the second mounting cylinder 222 are connected together by the connecting rib 270. Considering that the first filter element 310 and the second filter element 320 are horizontally mounted in the mounting cylinder 220, the first mounting cylinder 221 and the second mounting cylinder 222 have a certain length, and therefore the rear ends of the first mounting cylinder 221 and the second mounting cylinder 222 are connected together by the connecting rib 270. On the one hand, the structural strength of the rear ends of the first mounting cylinder 221 and the second mounting cylinder 222 can be ensured, and the breakage of the connection between the front end of the mounting cylinder 220 and the mounting plate 210 due to the heavy rear end of the mounting cylinder 220 when the heavy first filter element 310 and the second filter element 320 are respectively mounted into the first mounting cylinder 221 and the second mounting cylinder 222 can be avoided. On the other hand, the second mounting cylinder 222 is located below the first mounting cylinder 221. Considering that the first mounting cylinder 221 and the second mounting cylinder 222 are arranged at intervals, and the interval between the first mounting cylinder 221 and the second mounting cylinder 222 is used to arrange the external pipeline in the water purification equipment 10, the connecting rib 270 keeps the distance between the first mounting cylinder 221 and the second mounting cylinder 222 relatively consistent, so that the arrangement of the external pipeline arranged between the first mounting cylinder 221 and the second mounting cylinder 222 is not affected. Specifically, in the embodiment, the number of the connecting rib 270 is set to two, and the two connecting ribs 270 are arranged at intervals in the radial direction of the first filter element 310. Of course, the number of the connecting rib 270 can also be set to one, or even more.

[0064] Please refer to Figure 1 and Figure 2 In an embodiment, the water purification equipment 10 further comprises a water path plate module 500, the water path plate module 500 comprises a main water path plate 510, the main water path plate 510 is in water path communication with the water pump 400 and the filter element module 300, the main water path plate 510 is located between the base 110 and the water pump 400, and the main water path plate 510 is mounted on the mounting frame 200.

[0065] It should be noted that the water purification equipment 10 comprises the water path plate module 500, the water path plate module 500 is mainly used to form communication between the water paths of the first filter element 310 and the second filter element 320, and the water path plate module 500 is further provided with electromagnetic valves and check valves to control the opening degree of the water paths on the water path plate. The water path plate module 500 comprises a main water path plate 510, the main water path plate 510 is located between the base 110 and the water pump 400, the arrangement of the water path plate reasonably utilizes the remaining installation space in the water purification equipment 10, and the water path plate is mounted on the mounting frame 200 to fix the water path plate.

[0066] Specifically, the main waterway plate 510 has two plate surfaces arranged with water channels, one of which corresponds to one end of the second filter element 320. In this way, the space occupied by the waterway plate in the width direction of the water purification equipment 10 is minimized. Moreover, the length of the waterway plate corresponds to the height of the water purification equipment 10, and the width of the waterway plate corresponds to the width of the water purification equipment 10. The arrangement of the waterway plate can further reduce the space occupied by the waterway plate, thereby reducing the size of the water purification equipment 10.

[0067] The technical scheme of the present application can fix the water pump 400 on the positioning seat 230 of the mounting bracket 200. On the one hand, it can slow down the transmission of vibration when the water pump 400 is running, thereby achieving noise reduction. On the other hand, it can also make reasonable use of the space of the accommodating cavity 100a in the shell 100, reduce the structural arrangement on the base 110 of the water purification equipment 10, and thereby reduce the size of the water purification equipment 10. The top cover 130 and the middle shell 120 are detachably connected. Specifically, they are connected by clamping. The clamping connection is convenient to operate and can ensure the consistency of the appearance of the water purification equipment 10. At the same time, the separate fixed buckle clamping connection separates the fixing and limiting, making it easier to assemble and contact when the gap is large. When assembled in place, the gap between the two becomes almost no gap, making the connection and fixation of the top cover 130 and the middle shell 120 reliable and not loose, and having strong rigidity, further reducing the noise caused by the vibration of the water pump 400.

[0068] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
