Description

Technical Field

[0001] This application relates to the field of water purifier technology, specifically to a water purifier with a convenient pure water tank installation. Background Technology

[0002] Most existing water purifiers, especially household water purifiers, are equipped with a pure water tank. The pure water tank can be used to store the pure water filtered by the filter cartridge. When the user takes pure water, the pure water output from the pure water tank is faster than the pure water output from the filter cartridge while it is filtering, so as to achieve a large flow of water in a short time and reduce the user's waiting time to get water.

[0003] Traditional water purifiers primarily use two installation methods for their pure water tanks: one method integrates the pure water tank with the main support frame, eliminating the need for a separate tank installation process. However, when the tank needs replacement due to damage, all components mounted on the main support frame must be removed, and the entire frame replaced, resulting in high repair costs. The other method involves a separate design of the pure water tank and cover, secured with screws. This method suffers from cumbersome disassembly and assembly steps, high installation precision requirements, and a tendency to loosen over time. Furthermore, current technologies lack multi-directional limiting designs for the fit between the pure water tank and the main support frame, potentially causing the tank to shift during transportation or use, affecting the sealing of the water circuit connections. Therefore, there is an urgent need for a water purifier structure that enables rapid installation of the pure water tank and provides stable fixation. Utility Model Content

[0004] This application provides a water purifier with a convenient installation of a pure water tank, thereby improving the technical problems of inconvenient disassembly and assembly and high maintenance costs of pure water tanks in existing water purifiers.

[0005] The technical solution adopted in this application is as follows:

[0006] A water purifier with a convenient installation of a pure water tank includes a pure water tank, a shell, and a main support disposed within the shell. The main support has a tank mounting cavity for accommodating the pure water tank. The pure water tank has a locking protrusion and a limiting surface. The main support has a limiting protrusion and a stopping protrusion. The pure water tank is horizontally inserted into the tank mounting cavity along a first direction. The locking protrusion and / or the limiting protrusion are compressed and deformed, causing the locking protrusion to move from the first side of the limiting protrusion to the second side of the limiting protrusion, thereby preventing the pure water tank from exiting the tank mounting cavity in the opposite direction of the first direction. The stopping protrusion abuts against the limiting surface, thereby preventing the pure water tank from continuing to move along the first direction after being inserted into the tank mounting cavity.

[0007] In this technical solution, the pure water tank only needs to be horizontally pushed into the water tank mounting cavity of the main bracket to complete the locking process. No tools or complicated operations are required, enabling rapid installation and simplifying the installation process. The disassembly and maintenance of the pure water tank are also more convenient. The locking and limiting protrusions prevent the pure water tank from being pushed out of the water tank mounting cavity in the opposite direction, while the limiting protrusion restricts the pure water tank from being over-inserted into the water tank mounting cavity, forming a two-way limit on the pure water tank and providing double protection for the installation stability of the pure water tank. By utilizing the elastic deformation design of the locking protrusions and / or limiting protrusions, the pure water tank can be fixed without screws through the elasticity of the material, which helps to reduce maintenance costs.

[0008] The main support is provided with an arc-shaped support surface that supports the pure water tank. The arc-shaped support surface gradually rises along the first direction. Under the action of gravity, the pure water tank maintains the tendency to slide down along the arc-shaped support surface, so as to keep the locking protrusion in the position of abutting against the limiting protrusion.

[0009] In this technical solution, under the guidance of the arc-shaped support surface, the gravity of the pure water tank automatically maintains the contact pressure between the locking protrusion and the limiting protrusion, so that the pure water tank has a self-locking effect after installation, preventing the two from loosening due to the vibration of the whole machine, and ensuring the installation stability of the pure water tank; in addition, the arc-shaped support surface can also guide the pure water tank to slide in along the preset trajectory, reducing installation deviation.

[0010] Both the locking protrusion and the limiting protrusion are configured as a straight rib, and the locking protrusion and / or the limiting protrusion are provided with a guide slope for guiding the locking protrusion to slide from the first side of the limiting protrusion to the second side.

[0011] In this technical solution, both the locking protrusion and the limiting protrusion are set as straight ribs, which result in high stability after locking. The guide slope guides the locking protrusion to smoothly pass over the limiting protrusion, which helps to reduce the thrust required for horizontal installation of the pure water tank and also avoids wear on plastic parts caused by hard collision between the locking protrusion and the limiting protrusion, thus improving the durability of the structure.

[0012] The main support is provided with a filter element mounting cylinder located below the water tank mounting cavity, and the arc-shaped support surface is formed on the cylinder wall of the filter element mounting cylinder.

[0013] In this technical solution, the arc-shaped support surface is formed on the cylinder wall of the filter element mounting cylinder, reusing the filter element mounting cylinder structure, reducing the number of main support parts, lowering costs, achieving space integration, and facilitating maintenance.

[0014] The pure water tank is provided with a limiting plate, the limiting surface is formed on the limiting plate, the limiting plate is provided with a connecting hole that penetrates the limiting surface, and the stop protrusion is provided with a screw hole corresponding to the connecting hole.

[0015] In this technical solution, a large contact surface is provided by the limiting plate to disperse the pressure of the stop protrusion and prevent local deformation of the pure water tank; the connecting hole and screw hole can be used for additional fixing (such as transport locking screws) to adapt to different usage scenarios.

[0016] The main support is provided with a first limiting part and a second limiting part. The first limiting part abuts against the pure water tank to restrict the pure water tank from moving in the second direction, and the second limiting part abuts against the pure water tank to restrict the pure water tank from moving in the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0017] In this technical solution, based on the locking protrusion and the limiting protrusion locking and the stopping protrusion abutting against the limiting surface, the pure water tank is limited by the first limiting part and the second limiting part, so as to realize the all-round limiting and fixing of the pure water tank, eliminate the possibility of displacement of the pure water tank in the three directions of X, Y and Z axes, prevent the pure water tank from shifting, ensure the alignment of the water circuit interface of the pure water tank, and also help to improve the impact resistance and prevent the pure water tank from shaking and causing water leakage.

[0018] The main support is provided with heat preservation tank mounting base and water circuit board mounting base distributed on both sides of the water tank mounting cavity. The heat preservation tank mounting base and the water circuit board mounting base are connected by a bridging beam located above the water tank mounting cavity. The first limiting part is formed on the bridging beam and abuts against the top of the pure water tank.

[0019] In this technical solution, the bridging beam serves two purposes: firstly, by connecting the insulation tank mounting base and the water circuit board mounting base, it enhances the overall strength of the main support and prevents the main support from deforming due to the weight of the water tank; secondly, it limits the top of the pure water tank, restricting its vertical displacement and creating a clamping effect with the bottom arc-shaped support surface.

[0020] The bridging beam includes a front beam and a rear beam spaced apart along the first direction, and the first limiting portion includes a front limiting protrusion formed on the front beam and a rear limiting protrusion formed on the rear beam.

[0021] In this technical solution, the pure water tank is limited by the front and rear limit protrusions, which realizes the distribution of limit stress. Multi-point limiting reduces local stress concentration and helps to extend the life of plastic parts. In addition, it can increase the installation tolerance, allowing the pure water tank to be adjusted slightly in the front and rear directions, reducing the manufacturing precision requirements.

[0022] The second limiting portion includes a left limiting surface formed on the heat preservation tank mounting base and a right limiting surface formed on the water circuit plate mounting base. The left limiting surface and the right limiting surface are parallel and both extend vertically.

[0023] In this technical solution, the pure water tank is symmetrically constrained by the left and right limiting surfaces, and the parallel limiting surfaces on the left and right sides ensure that the pure water tank is installed in the center and avoids tilting. The limiting is achieved by using the existing heat preservation tank mounting base and water circuit board mounting base, which saves space.

[0024] The left limiting surface and / or the right limiting surface are provided with guide ribs for guiding the pure water tank into the water tank installation cavity.

[0025] In this technical solution, the guide rib has the effect of installation correction. It guides the pure water tank to align in the initial stage when the pure water tank is inserted into the water tank installation cavity, reducing the risk of jamming. The guide rib also has the function of wear resistance enhancement, reducing the risk of the pure water tank scratching the main support. In addition, as the contact point with the pure water tank, the guide rib can also be made of high hardness material to improve long-term reliability.

[0026] Thanks to the aforementioned technical solution, the pure water tank can be locked simply by horizontally pushing it into the tank mounting cavity of the main bracket, requiring no tools or complex operations, thus achieving rapid installation and simplifying the installation process. Disassembly and maintenance of the pure water tank are also more convenient. The locking and limiting protrusions prevent the pure water tank from reversing out of the tank mounting cavity, while the limiting protrusion restricts excessive insertion of the pure water tank into the mounting cavity, providing bidirectional limiting and doubly ensuring the stability of the pure water tank installation. Furthermore, the elastic deformation design of the locking and / or limiting protrusions allows for screwless fixing of the pure water tank through material elasticity, helping to reduce maintenance costs.

[0044] In the embodiments of this application, a water purifier with a conveniently installed pure water tank is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0045] like Figures 1 to 8 As shown, this application provides a convenient water purifier with a pure water tank, including a pure water tank 1, a shell (not shown in the figure), and a main support 2 disposed within the shell. The main support 2 has a water tank mounting cavity 21 for accommodating the pure water tank 1. The pure water tank 1 has a locking protrusion 11 and a limiting surface 121. The main support 2 has a limiting protrusion 22 and a stopping protrusion 23. The pure water tank 1 is horizontally inserted into the water tank mounting cavity 21 along a first direction. The locking protrusion 11 and / or the limiting protrusion 22 are compressed and deformed, causing the locking protrusion 11 to reach from the first side of the limiting protrusion 22 and lock onto the second side of the limiting protrusion 22, thereby restricting the pure water tank 1 from exiting the water tank mounting cavity 21 in the opposite direction of the first direction. The stopping protrusion 23 abuts against the limiting surface 121, thereby restricting the pure water tank 1 from continuing to move along the first direction after being inserted into the water tank mounting cavity 21. Specifically, Figure 1 and Figure 3 The images show the pure water tank 1 installed on the main support 2. Figure 1The arrow X indicates the first direction, which represents the width direction of the main support 2. In other embodiments, the first direction can also be set as the length direction of the main support 2 or an oblique direction that forms an angle with both the length and width directions.

[0046] The pure water tank 1 can be locked simply by horizontally pushing it into the water tank mounting cavity 21 of the main bracket 2, without the need for tools or complicated operations, achieving rapid installation and simplifying the installation process. Disassembly and maintenance of the pure water tank 1 are also more convenient. The locking protrusion 11 and the limiting protrusion 22 can prevent the pure water tank 1 from being pulled out of the water tank mounting cavity 21 in the opposite direction, and the stopping protrusion 23 restricts the pure water tank 1 from being over-inserted into the water tank mounting cavity 21, forming a two-way limit on the pure water tank 1, providing double protection for the installation stability of the pure water tank 1. Utilizing the elastic deformation design of the locking protrusion 11 and / or the limiting protrusion 22, the pure water tank 1 can be fixed without screws through the elasticity of the material, which helps to reduce maintenance costs. In a preferred embodiment, at least one of the main support 2 and the pure water tank 1 can be made of plastic material (such as ABS and PP), which has a certain toughness and elasticity. Alternatively, a metal material with elasticity can be used, so that the pure water tank 1 and the main support 2 can both deform during the mutual compression of the locking protrusion 11 and the limiting protrusion 22, thereby achieving the locking engagement of the locking protrusion 11 and the limiting protrusion 22.

[0047] As a preferred embodiment of this application, such as Figure 4 and Figure 5 As shown, the main support 2 is provided with an arc-shaped support surface 241 supporting the pure water tank 1. The arc-shaped support surface 241 gradually rises along the first direction. Under the action of gravity, the pure water tank 1 maintains a downward trend along the arc-shaped support surface 241, so as to keep the locking protrusion 11 in a position against the limiting protrusion 22. In this technical solution, after the pure water tank 1 is installed into the water tank installation cavity 21, it is supported by the arc-shaped support surface 241. Since it is not a planar support, under the guiding action of the arc-shaped support surface 241, the gravity of the pure water tank 1 automatically maintains the contact pressure between the locking protrusion 11 and the limiting protrusion 22, so that the pure water tank 1 has a self-locking effect after installation, preventing the two from loosening due to the vibration of the whole machine, and ensuring the installation stability of the pure water tank 1. In addition, the arc-shaped support surface 241 can also guide the pure water tank 1 to slide in along a preset trajectory, reducing installation deviation.

[0048] Regarding the formation method of the arc-shaped support surface 241, in the preferred embodiment, such as... Figure 4 and Figure 7As shown, the main support 2 is provided with a filter element mounting cylinder 24 located below the water tank mounting cavity 21, and the arc-shaped support surface 241 is formed on the cylinder wall of the filter element mounting cylinder 24. In this technical solution, by forming the arc-shaped support surface 241 on the cylinder wall of the filter element mounting cylinder 24, the structure of the filter element mounting cylinder 24 is reused, reducing the number of parts of the main support 2, reducing costs, achieving space integration, and facilitating maintenance. To accommodate the arc-shaped support surface 241, the pure water tank 1 can also be designed as an irregularly shaped structure with an arc at the bottom.

[0049] In a preferred embodiment, such as Figure 6 and Figure 7 As shown, both the locking protrusion 11 and the limiting protrusion 22 are configured as straight ribs. The locking protrusion 11 has a guide slope 111 for guiding the locking protrusion 11 to slide from the first side to the second side of the limiting protrusion 22. During the process of pushing the pure water tank 1 into the water tank installation cavity 21, the guide slope 111 guides the locking protrusion 11 to smoothly pass over the limiting protrusion 22, which helps to reduce the pushing force required for the horizontal installation of the pure water tank 1, and also avoids wear on the plastic parts caused by hard collision between the locking protrusion 11 and the limiting protrusion 22, thus improving the structural durability. The locking protrusion 11 and the limiting protrusion 22 are both configured as straight ribs, which result in high stability after locking. In addition, a guide slope can also be provided on the limiting protrusion 22. The guide slopes of the locking protrusion 11 and the limiting protrusion 22 cooperate with each other, making it easier to guide the locking protrusion 11 over the limiting protrusion 22 and lock it.

[0050] As a preferred embodiment of this application, such as Figure 1 , Figure 2 and Figure 6 As shown, the pure water tank 1 is provided with a limiting plate 12, a limiting surface 121 is formed on the limiting plate 12, the limiting plate 12 is provided with a connecting hole 122 penetrating the limiting surface 121, and the stop protrusion 23 is provided with a screw hole corresponding to the connecting hole 122. This application does not limit the location of the limiting plate 12 in the pure water tank 1. The figure shows an embodiment where the limiting plate 12 is located at the bottom of the pure water tank 1, which facilitates processing and assembly. Of course, the limiting plate 12 can also be located at the top, side, or other positions of the pure water tank 1. In this technical solution, the limiting plate 12 provides a large contact surface, dispersing the pressure of the stop protrusion 23 and preventing local deformation of the pure water tank 1; the connecting hole 122 and the screw hole can be used for additional fixing (such as transport locking screws), adapting to different usage scenarios.

[0051] In a preferred embodiment of this application, the main support 2 is provided with a first limiting part and a second limiting part. The first limiting part abuts against the pure water tank 1 to restrict the movement of the pure water tank 1 in a second direction, and the second limiting part abuts against the pure water tank 1 to restrict the movement of the pure water tank 1 in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. Specifically, Figure 4 In this technical solution, arrows Z and Y represent the second and third directions, respectively. Based on the locking protrusion 11 and the limiting protrusion 22 locking together, and the stopping protrusion 23 abutting against the limiting surface 121, the pure water tank 1 is limited by the first and second limiting parts, achieving omnidirectional limiting and fixing of the pure water tank 1. This eliminates the possibility of displacement of the pure water tank 1 in the X, Y, and Z axes, prevents the pure water tank 1 from shifting, ensures the alignment of the water circuit interfaces of the pure water tank 1, and also helps improve impact resistance, preventing the pure water tank 1 from shaking and causing leakage.

[0052] This application does not limit the specific structure of the first and second limiting parts; various structures can be selected, such as regular symmetrical structures, irregular structures, etc., and they can also be directly based on the functional components of the main support 2 itself. In a preferred embodiment, such as... Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the main support 2 is provided with a heat-insulating tank mounting seat 25 and a water circuit board mounting seat 26 distributed on both sides of the water tank mounting cavity 21. The heat-insulating tank mounting seat 25 and the water circuit board mounting seat 26 are connected by a bridging beam 27 located above the water tank mounting cavity 21. The first limiting part is formed on the bridging beam 27 and abuts against the top of the pure water tank 1. In this technical solution, the bridging beam 27, on the one hand, connects the heat-insulating tank mounting seat 25 and the water circuit board mounting seat 26, thereby enhancing the overall strength of the main support 2 and preventing the main support 2 from deforming due to the weight of the water tank. On the other hand, it limits the top of the pure water tank 1, restricting the vertical displacement of the pure water tank 1, and forming a clamping effect with the bottom arc-shaped support surface 241.

[0053] Regarding the structure of the first limiting part, preferably, as follows: Figure 7 and Figure 8As shown, the bridging beam 27 includes a front beam 271 and a rear beam 272 spaced apart along the first direction. The first limiting portion includes a front limiting protrusion 2711 formed on the front beam 271 and a rear limiting protrusion 2721 formed on the rear beam 272. Typically, multiple pipes connecting the insulated tank and the water circuit board need to be installed on the top of the water purifier. These pipes are located in the space between the front beam 271 and the rear beam 272. Therefore, based on this structure, by providing the front limiting protrusion 2711 on the front beam 271 and the rear limiting protrusion 2721 on the rear beam 272, the pure water tank 1 is limited by the front limiting protrusion 2711 and the rear limiting protrusion 2721, thus achieving stress dispersion. Multi-point limiting reduces local stress concentration, helping to extend the life of plastic parts. Furthermore, it increases installation tolerance, allowing for slight adjustments to the pure water tank 1 in the front-to-back direction, reducing manufacturing precision requirements.

[0054] Regarding the structure of the second limiting part, preferably, as follows: Figure 7 and Figure 8 As shown, the second limiting part includes a left limiting surface 251 formed on the heat preservation tank mounting base 25 and a right limiting surface 261 formed on the water circuit board mounting base 26. The left limiting surface 251 and the right limiting surface 261 are parallel and both extend vertically. In this technical solution, the left limiting surface 251 and the right limiting surface 261 form a symmetrical constraint on the pure water tank 1. The parallel limiting surfaces on the left and right sides ensure that the pure water tank 1 is installed in the center and avoids tilting. The limiting is achieved by using the existing heat preservation tank mounting base 25 and water circuit board mounting base 26, which saves space.

[0055] Furthermore, such as Figure 7 As shown, the left limiting surface 251 is provided with guide ribs 252 for guiding the pure water tank 1 into the water tank mounting cavity 21. The guide ribs 252 have an installation correction effect, guiding the pure water tank 1 to align initially when inserted into the water tank mounting cavity 21, reducing the risk of jamming. The guide ribs 252 also have a wear-resistant reinforcement function, reducing the risk of the pure water tank 1 scratching the main support 2. Furthermore, as the contact point with the pure water tank 1, the guide ribs 252 can be made of high-hardness materials to improve long-term reliability. In other embodiments, guide ribs 252 for guiding the pure water tank 1 into the water tank mounting cavity 21 can also be provided on the right limiting surface 261.

[0056] During the installation of the pure water tank 1, the installer pushes the pure water tank 1 horizontally into the water tank installation cavity 21 of the main support 2. The guide rib 252 guides the water tank into initial alignment. As the installation continues, the guide slope 111 of the locking protrusion 11 contacts the guide slope 111 of the limiting protrusion 22, causing elastic deformation of the main support 2 and the pure water tank 1, allowing the pure water tank 1 to pass through. When the limiting plate 12 contacts the stop protrusion 23, the locking protrusion 11 springs back and engages behind the limiting protrusion 22, completing the process. The water tank 1 is locked in a horizontal direction; due to gravity, the water tank 1 slides down the arc-shaped support surface 241, continuously pressing the locking protrusion 11. At the same time, the front limiting protrusion 2711 and the rear limiting protrusion 2721 of the bridging beam 27 restrict vertical movement, and the left limiting surface 251 and the right limiting surface 261 prevent lateral displacement. When disassembly is required, press at least one of the locking protrusion 11 and the limiting protrusion 22 to disengage the locking protrusion 11 from the limiting protrusion 22, and then pull the water tank 1 out in the opposite direction.
