Description

[0001] This utility model is a divisional application of application number 2024203942193, application date 2024-02-29, and invention title "Resin Tank and Water Softener". Technical Field

[0002] This utility model relates to the field of water purification technology, and in particular to resin tanks and water softeners. Background Technology

[0003] A water softener is a device that removes calcium and magnesium ions from water using ion exchange resin, thus reducing water hardness. Water softeners soften water by removing calcium and magnesium ions, making the water gentler and significantly improving the quality of water used for washing, bathing, and shampooing.

[0004] Existing water softeners are quite large, while the actual space in kitchens and bathrooms is limited, making it difficult for the size of the water softener to meet application needs. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the related art. To this end, this utility model proposes a resin tank that, compared with the resin tank of the prior art which has a single internal cavity structure, reduces the inner cavity diameter of the tank at the same height, and the overall width of the resin tank is also reduced, thereby further reducing the width of the water softener.

[0006] This utility model also proposes a water softener.

[0007] The resin tank according to a first aspect embodiment of the present invention includes:

[0008] The tank body has at least two inner cavities. The inlet of each inner cavity is connected to the outlet of the water softener valve through a first flow channel, and the outlet of each inner cavity is connected to the inlet of the water softener valve through a second flow channel.

[0009] According to an embodiment of this utility model, the resin tank is composed of two relatively independent cylindrical cavities. The axial direction of both cavities is the height direction of the water softener. A predetermined volume of resin is dispensed into the two cavities. The top of the tank has a first flow channel and a second flow channel connected to the water softener valve. Compared to the existing resin tank structure with a single cavity, the inner cavity diameter of the tank in this embodiment is reduced for the same height, resulting in a smaller overall width of the resin tank and further reducing the width of the water softener.

[0010] The water inlet and outlet of the two inner chambers are synchronized in all operating modes of the water softener. That is, the water softener valve can simultaneously introduce water into the two inner chambers through the first flow channel, or simultaneously allow water from the two inner chambers to flow into the water softener valve through the second flow channel, so that the two inner chambers of the tank body can work in a synchronous mode.

[0011] According to one embodiment of the present invention, it further includes:

[0012] Mounting plate, which is disposed on the top of the tank, is adapted to be inserted into the side plate of the water softener.

[0013] According to one embodiment of the present invention, the mounting plate is uniformly provided with a plurality of first insertion holes along the width direction of the tank body, and the side plate is provided with a first insertion block corresponding to the first insertion hole, wherein the first insertion hole and the first insertion block are detachably inserted.

[0016] The second mounting plate is disposed opposite to the first mounting plate on both sides of the tank in the width direction, and the vertical distance between the first mounting plate and the second mounting plate is less than or equal to the maximum width of the tank.

[0017] According to one embodiment of the present invention, the mounting plate is provided with a first limiting member suitable for fixing the brine suction pipe of the water softener, and there is a gap between the edge of the mounting plate and the edge of the brine tank of the water softener, and the first limiting member is located within the gap.

[0018] According to one embodiment of the present invention, the mounting plate is provided with a second insertion hole, which is adapted to be inserted into a second insertion block of the top cover plate of the water softener, and the second insertion block is always within the width range of the tank body.

[0019] According to one embodiment of the present invention, the mounting plate is provided with a third insertion hole, which is adapted to be inserted into the third insertion block of the rear cover plate of the water softener, and the third insertion block is always within the width range of the tank body.

[0020] According to one embodiment of the present invention, the tank body is further provided with a second limiting member, which is adapted to fix the overflow pipe of the water softener.

[0021] A water softener according to a second aspect embodiment of the present invention includes:

[0022] The housing includes side panels;

[0023] The resin tank as described above;

[0024] A water softener valve is disposed on the top of the resin tank and located between the mounting plates of the resin tank.

[0025] According to one embodiment of the present invention, the mounting plate includes a first mounting plate and a second mounting plate, and the water softener further includes:

[0026] A salt tank, the top of which is provided with a mounting base suitable for installing electronic components. The mounting base includes a first liner and a second liner. There is a gap between the first liner and the first mounting plate. The end of the second liner near the second mounting plate is bent toward the first liner to form a recess. The second mounting plate is inserted into the recess.

[0027] The above-described one or more technical solutions in the embodiments of this utility model have at least one of the following technical effects:

[0028] The resin tank provided by this utility model consists of two relatively independent cylindrical cavities. The axial direction of both cavities is along the height direction of the water softener. A predetermined volume of resin is dispensed into the two cavities. The top of the tank has a first flow channel and a second flow channel connected to the water softener valve. Compared to the existing resin tanks with a single cavity, this embodiment reduces the cavity diameter and overall width of the resin tank for the same height, thereby further reducing the width of the water softener.

[0029] The water inlet and outlet of the two inner chambers are synchronized in all operating modes of the water softener. That is, the water softener valve can simultaneously introduce water into the two inner chambers through the first flow channel, or simultaneously allow water from the two inner chambers to flow into the water softener valve through the second flow channel, so that the two inner chambers of the tank body can work in a synchronous mode.

[0049] The water softener's outer casing 100 houses a brine tank 200, a resin tank 300, and a softening valve 400. The softening valve 400 controls the water softener's switching modes, including: water production mode, water injection mode, brine extraction mode, and cleaning mode. In water production mode, raw water is fed into the resin tank 300 through the softening valve 400. The raw water in the resin tank 300 is softened by the resin to obtain soft water, which is then returned to the softening valve 400. Users can then obtain soft water from the soft water outlet of the softening valve 400. In water injection mode, water is injected into the brine tank 200 through the softening valve 400. Water, which can be raw water or softened water, is injected into the salt tank 200 to dissolve the salt in the salt tank 200. After the water is injected into the salt tank 200, the salt in the salt tank 200 can be dissolved for a period of time. This process can be called the salt dissolving mode. In the salt absorption mode, the brine in the salt tank 200 is sent into the resin tank 300 through the softened water valve 400. The water that has cleaned the resin in the resin tank 300 is discharged through the softened water valve 400. In the cleaning mode, raw water is introduced into the resin tank 300 through the softened water valve 400. The water that has cleaned the resin tank 300 is discharged through the softened water valve 400.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the utility model provides a resin tank 300, including a tank body 330 and a mounting plate 350; the mounting plate 350 is disposed on the top of the tank body 330 and is suitable for insertion into the side plate 170 of the water softener.

[0051] The resin tank 300 of this utility model embodiment has a tank body 330 as its main body. The mounting plate 350 is set on the top of the tank body 330 and its main function is to form a connection with the side plate 170 of the outer shell 100. The height direction of the water softener is the height direction of the tank body 330, the length direction of the water softener is the length direction of the tank body 330, and the width direction of the water softener is the width direction of the tank body 330. The tank body 330 is mainly divided into six directions: front, rear, left, right, upper, and lower. The front and rear directions are the length directions, and the front cover plate 140 and rear cover plate 110 of the outer shell 100 are set accordingly. The left and right directions are the width directions, and the first side plate 150 and second side plate 160 of the outer shell 100 are set accordingly. The upper and lower directions are the height directions, and the top cover plate 120 and base 130 of the outer shell 100 are set accordingly.

[0052] Compared to existing technologies that typically involve assembling the outer casing 100 (excluding the rear cover 110) and then inserting the resin tank 300 into the assembled portion before connecting the rear cover 110 to the rest of the outer casing 100, resulting in a consistent distance between the outer casing 100 and the resin tank 300, leading to a larger overall size of the outer casing 100 and a less compact overall structure for the water softener, the resin tank 300 in this invention provides a more robust and efficient assembly process during water softener assembly. After being fixed on the base 130, the side plate 170 can be directly plugged into the mounting plate 350, and then the other parts of the outer casing 100 can be assembled. This allows the side plate 170, as part of the outer casing 100, to directly encapsulate the resin tank 300 at the closest position to the outside of the resin tank 300, improving the structural compactness between the side plate 170 as the outer casing 100 and the water softening components, reducing the overall volume of the water softener. It also allows for a direct connection between the side plate 170 and the resin tank 300, improving the stability of the side plate 170 installation. Furthermore, compared to bolt-mounted assembly, the direct plug-in connection between the side plate 170 and the resin tank 300 facilitates the disassembly and assembly of the water softener.

[0053] According to one embodiment of the present invention, the mounting plate 350 is provided with a first insertion hole 351, which is adapted to be inserted into the first insertion block 171 of the side plate 170. In this embodiment, the insertion of the mounting plate 350 and the side plate 170 is achieved through the first insertion hole 351 and the first insertion block 171. The first insertion hole 351 is formed on the mounting plate 350 of the resin tank 300, and the first insertion block 171 is formed on the side plate 170. Correspondingly, they can be connected by snap-fit. The first insertion block 171 is inserted into the first insertion hole 351, and the first insertion hole 351 limits and fixes the first insertion block 171, thereby connecting the side plate 170 and the resin tank 300. The first insertion hole 351 releases the first insertion block 171, and the first insertion block 171 exits from the first insertion hole 351, thereby separating the side plate 170 from the resin tank 300.

[0054] In this embodiment, the first insertion hole 351 is disposed on the mounting plate 350, and the first insertion block 171 is disposed on the side plate 170. That is, when the first insertion block 171 is connected to the first insertion hole 351, the first insertion block 171 is always within the width range of the tank 330. Therefore, the first insertion hole 351 on the mounting plate 350 will not increase the width of the resin tank 300, thereby allowing the surface of the side plate 170 to fit against the surface of the mounting plate 350 after installation, reducing the width of the water softener. In other embodiments, the first insertion block 171 can also be disposed on the mounting plate 350, and the first insertion hole 351 can be disposed on the side plate 170 accordingly. However, this may result in the first insertion block 171 increasing the width of the resin tank 300, which needs to be avoided.

[0055] In this embodiment, the mounting plate 350 is provided with two first insertion holes 351 evenly along the width direction of the tank body 330, and the side plate 170 is provided with two first insertion blocks 171 at corresponding positions. In other embodiments, the positions and number of the first insertion holes 351 and the first insertion blocks 171 can be selected according to actual needs.

[0056] According to one embodiment of the present invention, the mounting plate 350 includes a first mounting plate 352 and a second mounting plate 353; the second mounting plate 353 and the first mounting plate 352 are disposed opposite each other on both sides of the tank body 330 in the width direction, and the vertical distance between the first mounting plate 352 and the second mounting plate 353 is less than or equal to the maximum width of the tank body 330. In this embodiment, the mounting plate 350 and the side plate 170 are disposed in a one-to-one correspondence, that is, the first mounting plate 352 and the second mounting plate 353 are disposed along the width direction of the tank body 330, the first side plate 150 is inserted into the outside of the first mounting plate 352, and the second side plate 160 is inserted into the outside of the second mounting plate 353, so that all the side plates 170 disposed in the width direction are in the form of insertion. To minimize the size of the water softener, the first mounting plate 352 and the second mounting plate 353 are positioned opposite each other and the distance between them is no greater than the maximum width of the tank 330. This ensures that the vertical distance between the first side plate 150 and the second side plate 160 is maintained at the maximum width of the tank 330, and the outer shell 100 has no additional space in the width direction.

[0057] In other embodiments, the mounting plate 350 and the side plate 170 may be selectively configured.

[0058] According to one embodiment of the present invention, the mounting plate 350 is provided with a first limiting member 354 suitable for fixing the brine suction pipe 410 of the water softener. A gap 230 exists between the mounting plate 350 and the brine tank 200 of the water softener, and the first limiting member 354 is located within the gap 230. In this embodiment, the resin tank 300 and the brine tank 200 are arranged sequentially along the length of the water softener. The water softener valve 400 is located at the top of the tank body 330. The brine suction pipe 410 of the water softener valve 400 is inserted into the brine tank 200. One end of the brine suction pipe 410 is connected to the water softener valve 400, and the other end passes through the mounting plate 350 and enters the brine tank 200. A gap 230 is left between the edge of the mounting plate 350 and the edge of the salt tank 200 to allow the brine suction pipe 410 to pass through. A first limiting member 354 is then set at the corresponding edge of the mounting plate 350. The brine suction pipe 410 is fixed at the first limiting member 354 as it passes through the gap 230, thereby fixing the brine suction pipe 410 and making the internal components of the water softener more integrated and orderly.

[0059] According to one embodiment of the present invention, the mounting plate 350 is provided with a second insertion hole 355, which is suitable for insertion with the second insertion block of the top cover plate 120 of the water softener. In this embodiment, the snap-fit ​​connection between the resin tank 300 and the top cover plate 120 is achieved through the second insertion hole 355. The second insertion hole 355 is formed on the mounting plate 350 of the resin tank 300, and the second insertion block is formed on the side plate 170. Correspondingly, they can be snap-fit ​​connected. The second insertion block is inserted into the second insertion hole 355, and the second insertion hole 355 limits and fixes the second insertion block, thereby connecting the top cover plate 120 and the resin tank 300. The second insertion hole 355 releases the second insertion block from the second insertion hole 355, and the second insertion block exits from the second insertion hole 355, thereby separating the top cover plate 120 from the resin tank 300.

[0060] In this embodiment, a plug-in connection is added between the top cover plate 120 and the mounting plate 350. During the assembly of the water softener, after the resin tank 300 is fixed to the base 130, the side plate 170 can be directly plugged into the mounting plate 350, and then the top cover plate 120 can be plugged into the mounting plate 350. This allows the top cover plate 120, as part of the outer shell 100, to directly encapsulate the resin tank 300 at the closest position to the outside of the resin tank 300, improving the structural compactness between the top cover plate 120 as the outer shell 100 and the water softening components, reducing the overall volume of the water softener. It also allows for a direct connection between the top cover plate 120 and the resin tank 300, improving the stability of the top cover plate 120 installation. Furthermore, compared to bolt-mounted assembly, the plug-in connection between the top cover plate 120 and the resin tank 300 facilitates the disassembly and assembly of the water softener.

[0061] In this embodiment, the second insertion hole 355 is disposed on the mounting plate 350, and the second insertion block is disposed on the top cover plate 120. That is, when the second insertion block is connected to the second insertion hole 355, the insertion block is always within the width range of the tank 330. Therefore, the second insertion hole 355 on the mounting plate 350 will not increase the width of the resin tank 300, thereby ensuring that the width of the top cover plate 120 after installation does not exceed the width of the resin tank 300, thus reducing the width of the water softener. In other embodiments, the second insertion block can also be disposed on the mounting plate 350, and the second insertion hole 355 can be disposed on the top cover plate 120 accordingly.

[0062] In this embodiment, the mounting plate 350 is provided with two second insertion holes 355 evenly along the width direction of the tank body 330, and the side plate 170 is provided with two second insertion blocks at corresponding positions. In other embodiments, the positions and number of the second insertion holes 355 and the second insertion blocks can be selected according to actual needs.

[0063] like Figure 3 and Figure 5As shown, according to one embodiment of the present invention, the mounting plate 350 is provided with a third insertion hole 356, which is suitable for insertion with the third insertion block 111 of the rear cover plate 110 of the water softener. In this embodiment, the snap-fit ​​connection between the resin tank 300 and the rear cover plate 110 is achieved through the third insertion hole 356. The third insertion hole 356 is formed on the mounting plate 350 of the resin tank 300, and the third insertion block 111 is formed on the side plate 170. Correspondingly, they can be snap-fit ​​connected. The third insertion block 111 is inserted into the third insertion hole 356, and the third insertion hole 356 limits and fixes the third insertion block 111, thereby connecting the rear cover plate 110 and the resin tank 300. The third insertion hole 356 releases the third insertion block 111, and the third insertion block 111 exits from the third insertion hole 356, thereby separating the rear cover plate 110 from the resin tank 300.

[0064] In this embodiment, a plug-in connection is added between the rear cover plate 110 and the mounting plate 350. During the assembly of the water softener, after the resin tank 300 is fixed on the base 130, the side plate 170 can be directly plugged into the mounting plate 350, then the rear cover plate 110 can be plugged into the mounting plate 350, and finally the top cover plate 120 can be plugged into the mounting plate 350. This allows the rear cover plate 110, as part of the outer shell 100, to directly encapsulate the resin tank 300 at the closest position to the outside of the resin tank 300, improving the structural compactness between the rear cover plate 110 as the outer shell 100 and the water softening components, reducing the overall volume of the water softener. It also allows for a direct connection between the rear cover plate 110 and the resin tank 300, improving the stability of the rear cover plate 110 installation. Furthermore, compared to bolt-mounted assembly, the plug-in connection between the rear cover plate 110 and the resin tank 300 facilitates the disassembly and assembly of the water softener.

[0065] In this embodiment, the third insertion hole 356 is disposed on the mounting plate 350, and the third insertion block 111 is disposed on the rear cover plate 110. That is, when the third insertion block 111 is connected to the third insertion hole 356, the insertion block is always within the width range of the tank 330. Therefore, the placement of the third insertion hole 356 on the mounting plate 350 will not increase the width of the resin tank 300, thereby ensuring that the width of the rear cover plate 110 after installation does not exceed the width of the resin tank 300, thus reducing the width of the water softener. In other embodiments, the third insertion block 111 may also be disposed on the mounting plate 350, and the corresponding third insertion hole 356 may be disposed on the rear cover plate 110.

[0066] In this embodiment, the mounting plate 350 is evenly provided with two third insertion holes 356 along the width direction of the tank body 330, and the side plate 170 is provided with two third insertion blocks 111 at corresponding positions. In other embodiments, the positions and number of the third insertion holes 356 and the third insertion blocks 111 can be selected according to actual needs.

[0067] like Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the tank 330 has at least two inner cavities 331. The inlets of both inner cavities 331 are connected to the outlet of the water softener valve 400 through a first flow channel 332, and the outlets of both inner cavities 331 are connected to the inlet of the water softener valve 400 through a second flow channel 333. In this embodiment, the interior of the tank 330 can be composed of two relatively independent cylindrical inner cavities 331. The axial direction of both inner cavities 331 is the height direction of the water softener, that is, a set volume of resin is dispensed into the two inner cavities 331. The top of the tank 330 is constructed with a first flow channel 332 and a second flow channel 333 connected to the water softener valve 400. Compared with the prior art resin tank 300, which has a single inner cavity 331, the diameter of the inner cavity 331 of the tank 330 in this embodiment is reduced for the same height, and the overall width of the resin tank 300 is also reduced, thereby further reducing the width of the water softener.

[0068] In this embodiment, the water inlet and outlet of the two inner cavities 331 are synchronized in all operating modes of the water softener. That is, the water softener valve 400 can simultaneously introduce water into the two inner cavities 331 through the first flow channel 332, or can simultaneously allow water from the two inner cavities 331 to flow into the water softener valve 400 through the second flow channel 333, so that the two inner cavities 331 of the tank body 330 are in a synchronous working mode.

[0069] like Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the tank 330 is further provided with a second limiting member 334, which is adapted to fix the overflow pipe 210 of the water softener. In this embodiment, the resin tank 300 and the brine tank 200 are arranged sequentially along the length of the water softener. One end of the overflow pipe 210 of the brine tank 200 is connected to the brine tank 200, and the other end extends along the length of the water softener to the rear cover plate 110. The second limiting member 334 is provided on the outer wall of the tank 330 at the position where the overflow pipe 210 passes, allowing the overflow pipe 210 to pass through. The second limiting member 334 guides the overflow pipe 210 while also supporting and fixing the overflow pipe 210, thereby fixing the overflow pipe 210 and making the internal device distribution of the water softener more integrated and orderly.

[0070] This utility model embodiment also provides a water softener, including a housing 100, a water softener valve 400, and a resin tank 300 as described in the above embodiment. The housing 100 includes a side plate 170; the water softener valve 400 is disposed on the top of the resin tank 300 and located between mounting plates 350.

[0071] The water softener of this utility model embodiment includes a mounting plate 350 comprising a first mounting plate 352 and a second mounting plate 353, and a side plate 170 comprising a first side plate 150 and a second side plate 160. The space between the first mounting plate 352 and the second mounting plate 353 serves as the space for installing the water softener valve 400, providing a certain degree of protection for the water softener valve 400.

[0072] According to one embodiment of the present invention, the water softener further includes a brine tank 200. The top of the brine tank 200 is provided with a mounting base 220 suitable for installing electronic components. The mounting base 220 includes a first liner 221 and a second liner 222. There is a gap 230 between the first liner 221 and the first mounting plate 352. The end of the second liner 222 near the second mounting plate 353 is bent toward the first liner 221 to form a recess 240. The second mounting plate 353 is inserted into the recess 240.

[0073] In this embodiment, the combined height of the salt tank 200 and its top mounting base 220 is flush with the height of the resin tank 300, thus ensuring the height limit of the water softener. The first liner 221 and the first mounting plate 352 are sequentially arranged along the length of the water softener, as are the second liner 222 and the second mounting plate 353. A gap 230 is provided between the first liner 221 and the first mounting plate 352 for the passage of the brine suction pipe 410. That is, the first liner 221 and the first mounting plate 352 are only positionally corresponding, but do not have any... Upon contact, the second liner 222 bends around the first liner 221, forming a recess 240 by bending the second liner 222 into the space between the two liners. The second mounting plate 353 is inserted into the recess 240 from the edge of the second liner 222, making the outer surface of the second liner 222 flush with the outer surface of the second mounting plate 353. This ensures a neat installation without any protruding structures, thereby ensuring that after the second side plate 160 is inserted into the second mounting plate 353, there is no gap 230 between the second side plate 160 and the second mounting plate 353, reducing the width of the water softener.

[0074] According to one embodiment of the present invention, a slot 310 is provided in one of the tank body 330 and the rear cover plate 110, and a third insertion block 111 is provided in the other of the tank body 330 and the rear cover plate 110. The third insertion block 111 is inserted into the slot 310. In this embodiment, the snap-fit ​​between the tank body 330 and the rear cover plate 110 is achieved by the third insertion block 111 and the slot 310. The third insertion block 111 and the slot 310 can be formed on the tank body 330 and the rear cover plate 110 respectively, and can be snap-fitted together by corresponding cooperation. When the third insertion block 111 is inserted into the slot 310, the slot 310 limits and fixes the third insertion block 111, thereby connecting the rear cover plate 110 and the tank body 330. When the slot 310 releases the limitation on the third insertion block 111, the third insertion block 111 is withdrawn from the slot 310, thereby separating the rear cover plate 110 from the tank body 330.

[0075] In this embodiment, the third insertion block 111 is disposed on the rear cover plate 110, and the slot 310 is disposed on the tank body 330. There are six third insertion blocks 111 in total. Three third insertion blocks 111 are evenly disposed on each side of the rear cover plate 110 in the width direction, and six slots 310 are disposed on the tank body 330 at corresponding positions. In other embodiments, the placement position and number of the third insertion blocks 111 and the slots 310 can be selected according to actual needs.

[0076] According to one embodiment of the present invention, the rear cover plate 110 includes a plate body 112 and a flange 113. The width of the plate body 112 is less than or equal to the width of the tank body 330. The flange 113 is disposed on both sides of the plate body 112 along the height direction of the plate body 112. The flange 113 extends into the accommodating space. The flange 113 is provided with a notch 114. The third insertion block 111 is disposed in the notch 114.

[0077] In this embodiment, the rear cover plate 110 is mainly divided into three parts along its width direction. One part is the plate body 112, and the other two parts are the flanges 113 located on both sides of the width direction of the plate body 112. It can also be understood that the two sides of the width direction of the rear cover plate 110 are bent towards the direction of the accommodating space. The length direction of the flange 113 is the height direction of the plate body 112, and the width direction of the flange 113 is the extension direction towards the accommodating space. Therefore, the width of the plate body 112 is the width of the rear cover plate 110 itself. In order to ensure that the volume of the outer shell 100 is minimized, the width of the rear cover plate 110 must not exceed the width of the tank 330, and the width of the outer shell 100 must be as close as possible to the width of the tank 330. After the other parts of the outer shell 100 are installed, there is no other remaining space in the width direction.

[0078] The flange 113 is provided with a notch 114, and the third plug block 111 is provided at the notch 114. It can maintain the same position as the flange 113 on both sides of the notch 114, that is, the third plug block 111 and the flange 113 are integrated into one, which further makes the structure of the rear cover plate 110 more compact and does not occupy other structures and space.

[0079] In this embodiment, the width of the plate body 112 is the same as the width of the tank body 330, that is, the outer surface of the flange 113 is flush with the outer surface of the tank body 330 at its maximum width. Since the third insertion block 111 is integrated with the flange 113, a corresponding recess is provided on the tank body 330 to form a slot 310. After the third insertion block 111 is inserted into the slot 310, it can also ensure that the connection position between the tank body 330 and the rear cover plate 110 is flat and without protrusion, and will not increase the width of the outer shell 100.

[0080] According to one embodiment of the present invention, the tank body 330 is provided with positioning holes 320, and the rear cover plate 110 is provided with a plurality of positioning posts 115. The positioning posts 115 are inserted into the positioning holes 320, and the plurality of positioning posts 115 are evenly distributed along the height direction of the rear cover plate 110. In this embodiment, the tank body 330 and the rear cover plate 110 also cooperate through positioning parts. During the connection between the rear cover plate 110 and the tank body 330, the positioning posts 115 of the rear cover plate 110 are inserted into the corresponding positioning holes 320 on the tank body 330. The positioning holes 320 can restrict the movement of the positioning posts 115 within the range involved in the height and width directions of the rear cover plate 110, thereby realizing the positioning and restriction of the rear cover plate 110 during installation.

[0081] In this embodiment, the positioning posts 115 are divided into two groups, both of which are set on the plate body 112. The two groups of positioning posts 115 are respectively set close to the two flanges 113. Each group of positioning posts 115 consists of multiple positioning posts 115. The multiple positioning posts 115 are evenly distributed along the height direction of the rear cover plate 110, which restricts the position of the rear cover plate 110 and prevents the rear cover plate 110 from deforming, increases the structural strength of the rear cover plate 110, and thus reduces the gap between the flanges 113 and the first side plate 150 and the second side plate 160 of the outer shell 100 during installation.

[0082] According to one embodiment of the present invention, a connecting plate 340 is further provided on the tank body 330. The connecting plate 340 is located between the tank body 330 and the rear cover plate 110. The connecting plate 340 is provided with a slot 310 and a positioning hole 320. In this embodiment, the resin tank 300 is divided into three parts: the tank body 330, the mounting plate 350, and the connecting plate 340. The connecting plate 340 is provided on the side of the tank body 330 facing the rear cover plate 110. The connecting plate 340 is integrated with the tank body 330. The connecting plate 340 extends along the height direction of the tank body 330 and corresponds to the rear cover plate 110. The corresponding positioning hole 320 and slot 310 are provided on the connecting plate 340. That is, the connecting plate 340 provides a planar structure for the installation connection between the resin tank 300 and the rear cover plate 110, making the connection more convenient and the structure more stable and firm.

[0083] It is understandable that the resin tank 300 is cylindrical, and setting the groove 310 and positioning hole 320 on the outer circumference of the cylindrical wall is not reliable from the perspective of processing, manufacturing and connection performance. Therefore, a connecting plate 340 is added to the outer wall of the tank body 330. The connecting plate 340 is a flat plate, and the positioning hole 320 and the groove 310 are constructed on the flat plate to improve the reliability of the connection structure.

[0084] According to one embodiment of the present invention, the edge of the connecting plate 340 is provided with a bent portion 341 corresponding to the flange 113, and the bent portion 341 is recessed to form a groove 310. In this embodiment, the edge of the connecting plate 340 forms a bent portion 341 in the direction of the rear cover plate 110, that is, the bent portion 341 corresponds to the flange 113. After the rear cover plate 110 is connected to the resin tank 300, the flange 113 is stacked on the outside of the bent portion 341 and is tightly fitted to the outer surface of the bent portion 341. Since the flange 113 integrates a third insertion block 111, the bent portion 341 forms a groove 310 by recessing at the position corresponding to the third insertion block 111, and is connected to the third insertion block 111.

[0085] The bending part 341 serves to support the flange 113 and enhance its structural strength, while also increasing the structural compactness of the rear cover plate 110 until it is snapped into the resin tank 300.

[0086] According to one embodiment of the present invention, the connecting plate 340 is further provided with reinforcing ribs 342, which abut against the rear cover plate 110. In this embodiment, reinforcing ribs 342 are provided between the bent portions 341 on both sides of the connecting plate 340. The reinforcing ribs 342 are arranged in multiple layers from top to bottom, and both ends of each layer of reinforcing ribs 342 are connected to two bent portions 341, thereby enhancing the structural strength of the connecting plate 340 and preventing deformation of the bent portions 341 of the connecting plate 340. After the rear cover plate 110 is snapped onto the connecting plate 340, the edge of the reinforcing rib 342 near the rear cover plate 110 abuts against the inner surface of the plate body 112 of the rear cover plate 110. That is, the reinforcing rib 342 provides support for the plate body 112 in the stiffness direction of the rear cover plate 110, further improving the structural strength of the rear cover plate 110 after it is installed on the resin tank 300 and preventing deformation.
