[0037] A water softener is a device that uses cation exchange resin to remove calcium and magnesium ions from water, reduce the hardness of raw water, and thus soften hard water. Water softeners are currently widely used in industrial and energy systems and have strong equipment attributes. In household use, the soft water produced by a water softener usually has the effects of reducing scale in water heating equipment such as water heaters, wall-mounted boilers, electric water heaters, and bathrooms, avoiding pipe blockage, reducing the attenuation of heat exchange efficiency of heating equipment, reducing the use of detergents, being more friendly to human skin, and making clothes softer and brighter in color after washing.

[0038] In the relevant technical field, the water softening device is mainly composed of four parts: control valve, resin tank, salt absorber, and salt box. The core filter material of the water softening device is softening resin, which is installed in the resin tank. This shows the importance of the resin tank. When the water softening device is working, the tank body is subjected to a large water pressure, and when the tank body is installed on the water channel component, the installation structure between the tank body and the water channel component is subjected to a large pressure. The existing installation structure is difficult to ensure the connection strength.

[0039] The utility model provides a resin tank component and a water softening device.

[0040] In the embodiment of the present utility model, Figures 1 to 6 As shown, the tank body 100 includes a first end and a second end that are relatively arranged, and the tank body 100 has a accommodating cavity 110 for accommodating resin and a tank mouth 131 connected with the accommodating cavity 110, and the tank mouth 131 is arranged at the end of the first end, and a first clamping portion 133 is arranged along the circumference of the tank mouth 131; the water channel component 200 is provided with a connecting port, which is connected with the tank mouth 131, and a second clamping portion 211 corresponding to the first clamping portion 133 is arranged on the outer peripheral side of the connecting port, and the second clamping portion 211 is connected with the first clamping portion 133 by screwing and clamping, so as to connect the water channel component 200 and the tank body 100.

[0041] The tank body 100 is generally in the shape of a hollow cylinder, and a receiving chamber 110 is formed inside the tank body 100, wherein the receiving chamber 110 is the main part of the resin tank and is used to store the resin. The receiving chamber 110 can be designed in different shapes and sizes according to application requirements to adapt to different resin volumes and performance requirements, which are not particularly limited here.

[0042] A tank opening 131 is provided on the end surface of one end of the tank body 100, and the tank opening 131 is used to allow and control the fluid to flow into and out of the accommodating chamber 110. The size and shape of the tank opening 131 can be adjusted according to actual needs to optimize the flow properties of the resin. At the same time, the design of the tank opening 131 can reduce the flow area of ​​the fluid between the water channel component 200 and the tank body 100, thereby reducing the force-bearing surface between the tank body 100 and the water channel component 200, thereby reducing the opening force.

[0043] A tapered portion 132 is provided on the outer side of the tank mouth 131 to further optimize the contact area between the resin tank and the water path component 200. The gradually shrinking portion can better adapt to the shape and size of the water path component 200 and guide the fluid, making it easier for the fluid to adapt to changes in the accommodating chamber 110, so as to cooperate with the tank mouth 131 to improve the connection stability and tightness between the two.

[0044] The tapered portion 132 is provided with a first clamping portion 133 along the circumferential side of the tank mouth 131, and the first clamping portion 133 is used to clamp with the second clamping portion 211 on the water channel member 200. Through the design of the first clamping portion 133 and the second clamping portion 211, the connection between the water channel member 200 and the tank body 100 can be completed simply and quickly. At the same time, since the first clamping portion 133 is provided on the tapered portion 132, the stability and reliability of the connection can be ensured, and the radial area of ​​the resin tank assembly 10 can be effectively reduced. In addition, the connection by the rotary clamping method can reduce the workload and difficulty during the connection, and improve the practicality and convenience of the overall assembly.

[0045] A communication port is provided on the water channel component 200 so that the water flow can be conducted and distributed through the water channel component 200. In the present application, the communication port is used to connect with the tank mouth 131 of the tank body 100. The shape and size of the communication port should match the tank mouth 131 to ensure a tight connection between the two. A second clamping portion 211 corresponding to the first clamping portion 133 is provided on the peripheral side of the communication port, and the second clamping portion 211 matches the first clamping portion 133 on the tank body 100. Through the rotary clamp connection between the first clamping portion 133 and the second clamping portion 211, the water channel component 200 can be firmly connected to the tank body 100. This connection method can provide better stability and reliability, ensuring that the water channel component 200 will not loosen or fall off during use. The present application is connected by a rotary clamp between the first clamping portion 133 and the second clamping portion 211, which can be put in place by rotating at a small angle, which is simple and fast, and can effectively reduce installation time and workload. At the same time, the screw-on connection can also provide better stability, ensuring that the connection between the water channel component 200 and the tank body 100 is firm and reliable.

[0046] The present application sets a tank mouth 131 and sets a first clamping portion 133 and a second clamping portion 211 on the surrounding side of the tank mouth 131, and the first clamping portion 133 of the tank body 100 is screwed and connected with the second clamping portion 211 of the water path component 200 to tightly connect the water path component 200 and the tank body 100 to ensure the stability and reliability of the connection; and while the screwing and locking are in cooperation, the tank body 100 is connected with the water path component 200 through the docking between the tank mouth 131 and the connecting port, thereby improving the ease of installation.

[0047] Reference Figures 3 to 6 According to an embodiment of the utility model, the first clamping part 133 includes a plurality of clamping bosses 133a, and the plurality of clamping bosses 133a are arranged along the circumference of the tank mouth 131. The clamping bosses 133a and the outer wall of the tapered part 132 form a clamping groove 133b, and the second clamping part 211 is slidably clamped with the clamping groove 133b. It can be understood that the clamping boss 133a cooperates with the outer wall of the tapered part 132 to form a clamping groove 133b on the side away from the tank mouth 131. In this way, when the second clamping part 211 is slidably clamped with the clamping groove 133b, the clamping boss 133a can provide a greater axial abutment force, and can cooperate with the second clamping part 211 to resist a greater opening force, and can be fixed in place more stably. Specifically, by slidingly clamping the second clamping part 211 of the waterway member 200 with the clamping groove 133b of the tank body 100, a tight connection between the two can be ensured. Due to the design of the clamping boss 133a and the clamping slot 133b, the connection part can withstand greater external force and vibration, thereby improving the stability of the entire assembly. In addition, this design is also conducive to reducing the problem of loosening or falling off caused by vibration or other external factors during use.

[0048] Referring to Figure 5 and Figure 6 , according to an embodiment of the present utility model, the second clamping portion 211 includes a plurality of clamping protrusions 211a, the clamping protrusions 211a are arranged corresponding to the clamping grooves 133b, and the clamping protrusions 211a are in sliding fit with the clamping grooves 133b. Through the cooperation of the plurality of clamping protrusions 211a and the clamping grooves 133b in this application, the cooperation efficiency of the rotary clamping connection can be effectively improved, and it can be in place with only a small-angle rotation, simplifying the installation process and improving the installation efficiency. At the same time, the arrangement of the plurality of clamping protrusions 211a can also disperse the force at the connection part, improving the strength and stability of the overall structure. In this way, the multi-point connection method can better resist external forces and vibrations, reducing the possibility of loosening or falling off during use. And due to the strengthening of the connection part, the service life of the entire resin tank assembly 10 is also extended.

[0049] Referring to Figure 5 , according to an embodiment of the present utility model, the protruding height of the clamping boss 133a in the radial direction is K0, where 2mm < K0 < 10mm, or K0 = 2mm, or K0 = 10mm. It can be understood that, under the condition that other parameters remain unchanged, the higher the protruding height of the clamping boss in the radial direction, the deeper the depth of the clamping groove 133b formed between the clamping boss 133a and the tank body 100. Therefore, the larger the abutting surface area provided when abutting against the clamping protrusions 211a, thereby ensuring the abutting strength between the clamping boss 133a and the clamping protrusions 211a; however, if the protruding height of the clamping boss 133a in the radial direction is too high, it will increase the radius of the tank body 100 in the axial direction, resulting in an increase in the volume of the tank body 100; and if the protruding height of the clamping boss 133a in the radial direction is too small, due to the existence of assembly errors and process errors, the abutting area between the clamping boss 133a and the clamping protrusions 211a cannot be guaranteed, and the reliability of the connection structure cannot be guaranteed; therefore, in this embodiment, the protruding height K0 of the clamping boss 133a in the radial direction is limited between 2mm and 10mm to ensure the abutting strength between the clamping boss 133a and the clamping protrusions 211a.

[0050] Optionally, the protruding height K0 of the clamping boss 133a in the radial direction can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm or 10mm, etc., and can be selected according to specific design requirements, and no special limitation is made here.

[0051] Referring to Figure 5, according to an embodiment of the present utility model, the axial thickness of the clamping boss 133a is H0, where 5mm < H0 < 16mm, or H0 = 5mm, or H0 = 16mm. It can be understood that the thicker the axial thickness of the clamping boss 133a is, the stronger the axial abutting strength between the clamping boss 133a and the clamping protrusion 211a. And when the radially protruding height of the clamping boss 133a is larger, in order to prevent structural fracture between the clamping boss 133a and the can body 100 during abutment, it is also necessary to increase the axial thickness of the clamping boss 133a, so as to increase the connection area between the clamping boss 133a and the can body 100, and further improve the structural stability between the clamping boss 133a and the can body 100.

[0052] Optionally, the axial thickness HO of the clamping boss 133a can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm or 16mm, etc., and can be selected according to specific design requirements, and no special limitation is made here.

[0053] Refer to Figure 6 , according to an embodiment of the present utility model, the radially protruding height of the clamping protrusion 211a is K1, where 2mm < K1 < 10mm, or K1 = 2mm, or K1 = 10mm. It can be understood that as the radially protruding height of the clamping boss 133a increases, the depth of the card slot 133b formed between the clamping boss 133a and the outer wall surface of the can body 100 also increases. Therefore, in this embodiment, the height K1 of the clamping protrusion 211a can be correspondingly set according to the size of the height K0 of the clamping boss 133a to increase the abutting area between the clamping protrusion 211a and the card slot 133b and enhance the abutting strength.

[0054] Optionally, the radially protruding height K1 of the clamping boss 133a can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm or 10mm, etc., and can be selected according to specific design requirements, and no special limitation is made here.

[0055] Refer to Figure 6According to an embodiment of the present invention, the thickness of the clamping protrusion 211a along the axial direction is H1, wherein 5mm

[0056] Optionally, the thickness H1 of the clamping protrusion 211a along the axial direction can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm or 16mm, etc., which can be selected according to specific design requirements and is not particularly limited here.

[0057] Reference Figure 3 and Figure 5 According to an embodiment of the utility model, the card slot 133b has a card entrance 133c and a stopper 133d, and the card entrance 133c and the stopper 133d are arranged at the two ends of the card slot 133b. It can be understood that the card entrance 133c is opened along the circumference of the tank body 100, and the card entrance 133c is connected to one end of the card slot 133b. The card entrance 133c is used to guide the second clamping part 211 to be correctly inserted into the card slot 133b, avoid misalignment during installation, and ensure that the two parts can be accurately aligned. The stopper 133d is also arranged along the circumference of the tank body 100, and is located at the other end of the card slot 133b opposite to the card entrance 133c. Its function is that when the second clamping part 211 is fully inserted into the card slot 133b, the stopper 133d plays a role of a stop limit, restricting the second clamping part 211 from moving out of the card slot 133b. This ensures the stability of the connection and prevents accidental detachment due to vibration or external force during use. The design of the card entrance 133c and the stopper 133d can also simplify the installation process, because the user only needs to insert the second card connection part 211 from the card entrance 133c, and then rotate it until the second card connection part 211 abuts against the stopper 133d to complete the installation. And when maintenance or replacement of parts is required, the disassembly process is also made simpler.

[0058] Reference Figure 5 and Figure 6 ​According to an embodiment of the present invention, one of the slot 133b or the clamping protrusion 211a is provided with an anti-loosening protrusion 133e, and the other is correspondingly provided with an anti-loosening recess 211b. Specifically, the second clamping portion 211 of the water channel component 200 and the first clamping portion 133 on the tank body 100 are respectively designed with a small cylindrical concave and convex anti-loosening recess 211b and an anti-loosening protrusion 133e. During the rotation of the water channel component 200, the anti-loosening recess 211b and the anti-loosening protrusion 133e have a certain interference. When the second protrusion on the water channel component 200 is rotated to abut against the stopper 133d, the interference is eliminated, and the anti-loosening protrusion 133e is clamped into the anti-loosening recess 211b, so that the water channel component 200 needs a larger torque to rotate and loosen. In this way, the anti-loosening protrusion 133e and the anti-loosening recess 211b cooperate to effectively prevent the connection part from loosening through a mutual physical locking mechanism. The anti-loosening protrusion 133e and the anti-loosening recess 211b precisely cooperate to make the connection between the second clamping part 211 and the first clamping part 133 more secure.

[0059] Reference Figure 5 According to an embodiment of the utility model, an avoidance portion 133f is formed between two adjacent clamping bosses 133a, and two adjacent clamping grooves 133b along the screwing direction, the clamping inlet 133c of the rear clamping groove 133b is connected to the avoidance portion 133f, and the front clamping groove 133b is separated from the avoidance portion 133f by the stopper 133d. It can be understood that the avoidance portion 133f is used to axially avoid the second protrusion. Specifically, by providing the avoidance portion 133f, a clear channel is formed between adjacent clamping bosses 133a, so that the second clamping portion 211 can slide and clamp more smoothly. Possible collisions between the clamping bosses 133a are avoided, and the stability and reliability of the clamping are improved. Of the two adjacent slots 133b along the screwing direction, the snap-in entrance 133c of the rear slot 133b is connected to the escape portion 133f, while the front slot 133b is separated from the escape portion 133f by the stopper 133d, so that the second snap-in portion 211 can smoothly enter the rear slot 133b during the sliding snap-in process, and prevent the corresponding second snap-in portion 211 from sliding into the front slot 133b, thereby avoiding possible installation misalignment and improving the effectiveness and reliability of assembly and disassembly.

[0060] Reference Figure 3 and Figure 4According to an embodiment of the utility model, the tank body 100 includes a first tank body 120 and a second tank body 130, and the tank mouth 131 is arranged on the second tank body 130. The first tank body 120 is arranged in a cylindrical shape with one end open, and the second tank body 130 is connected to the opening, and the first tank body 120 and the second tank body 130 are enclosed together to form a receiving cavity 110. It can be understood that in the application, the tank body 100 can be an integrally formed setting or a split-body setting. This embodiment is described by taking the tank body 100 including the first tank body 120 and the second tank body 130 as an example, and other embodiments can refer to this embodiment for implementation, wherein the first tank body 120 is arranged in a cylindrical shape with one end open, and the second tank body 130 is connected to the opening, and the first tank body 120 is enclosed together to form a receiving cavity 110. For example, it is convenient to set other components in the receiving cavity 110. The design of the first tank body 120 and the second tank body 130 makes the resin tank more flexible and can adapt to different application scenarios and needs. For example, the thickness or shape of the second tank body 130 may be adjusted according to actual needs to adapt to specific installation conditions or usage requirements.

[0061] Reference Figures 3 to 5 According to an embodiment of the utility model, a plug-in column 134 is extended from the outer periphery of the tank mouth 131 toward the direction of the water channel component 200, and a plug-in interface is provided on the water channel component 200. The plug-in column 134 and the plug-in interface are movably plugged together to connect the accommodating chamber 110 with the water channel component 200. In this embodiment, the connectivity between the accommodating chamber 110 and the water channel component 200 is enhanced by the cooperation of the plug-in column 134 and the plug-in interface.
