Abstract
Description
Technical Field
[0001] This utility model relates to the field of drinking water equipment technology, and more specifically, to a pipeline machine. Background Technology
[0002] As a common instant hot water dispenser, a water dispenser requires an external RO reverse osmosis water purifier to operate normally. Specifically, the RO reverse osmosis water purifier performs multi-stage fine filtration and purification on the raw water, delivering the purified water to the water dispenser. The water dispenser then heats or cools the water according to the user's needs, providing drinking water at a suitable temperature. However, the water dispenser and water purifier need to be installed separately, resulting in a large overall space occupation and complex piping connections. This limitation is particularly pronounced in homes or offices with limited space, making the equipment less suitable for most applications.
[0003] To address these issues, related technologies have attempted to add a filter cartridge inside the water dispenser, aiming to achieve integrated water purification and heating / cooling functions. However, in actual use, bacteria easily grow inside the filter cartridge over time, requiring timely replacement to ensure drinking water safety. However, in these technologies, the filter cartridge is installed inside the device and connected to the water pipes, making installation and removal cumbersome and inconvenient for filter replacement. Utility Model Content
[0004] The problem this utility model solves is: how to address the technical issue of inconvenient filter replacement in pipeline machines with filter cartridges.
[0005] To address the aforementioned problems, this utility model provides a pipeline machine, comprising a body, a mounting sleeve, and a filter element. The mounting sleeve is disposed inside the body, and the bottom plate of the body has an inlet corresponding to the mounting sleeve. The filter element is configured to be inserted into the mounting sleeve through the inlet. A locking structure is provided between the mounting sleeve and the filter element to lock the filter element within the mounting sleeve. The mounting sleeve is provided with an inlet pipe and an outlet pipe. One end of the inlet pipe is inserted into the inlet of the filter element, and one end of the outlet pipe is inserted into the outlet of the filter element.
[0006] Furthermore, the mounting sleeve includes a sleeve head, a sleeve, and a base. The sleeve head is connected to the inner wall of the machine body via a connecting piece. The base is connected to the bottom plate of the machine body and covers the insertion port. The two ends of the sleeve are respectively fitted onto the inner peripheral wall of the sleeve head and the outer peripheral wall of the base.
[0007] Furthermore, the locking structure includes a groove surrounding the inner wall of the sleeve and a buckle surrounding the outer peripheral wall of the top of the filter element. When the top of the filter element is inserted into the mounting sleeve and rotates relative to it, the buckle slides along the sliding path of the groove and engages.
[0008] Furthermore, the sliding path of the slot is provided with an upwardly inclined first guide slope, and the end of the buckle is provided with a downwardly inclined second guide slope. The second guide slope cooperates with the first guide slope to guide the buckle into the slot.
[0009] Furthermore, the sliding path end of the slot is provided with a protrusion, and the buckle is provided with a groove on the side near the second guide slope. When the buckle slides to the end of the slot, the protrusion engages with the groove to limit its position.
[0010] Furthermore, the end of the buckle away from the second guide slope is provided with a radially extending first abutment block. When the protrusion is engaged in the groove, the end of the first guide slope abuts against the first abutment block.
[0011] And / or,
[0012] The end of the slot away from the first guide slope is provided with a radially extending second abutment block. When the protrusion is engaged in the groove, the end of the second guide slope abuts against the second abutment block.
[0013] Furthermore, the inner peripheral wall of the top end of the sleeve is provided with a first abutment platform for abutting against the bottom of the sleeve head; the outer peripheral wall of the bottom end of the sleeve is provided with a second abutment platform for abutting against the top end of the base; the bottom end of the base is connected to the inner peripheral wall of the insertion port.
[0014] Furthermore, the body is provided with a cover plate at the insertion port, and a handle is provided on the outer side of the cover plate. The base is provided with a third abutment platform on the inner peripheral wall at the insertion port. When the cover plate is closed, the outer peripheral edge of the cover plate abuts against the third abutment platform. A fastening structure is provided between the inner peripheral wall of the base and the outer peripheral wall of the cover plate for fastening the cover plate to the insertion port.
[0015] Furthermore, the fastening structure includes a positioning groove surrounding the inner peripheral wall of the base and a positioning block located on the outer peripheral wall of the cover plate. The positioning groove is provided with a locking block. When the positioning block rotates into the positioning groove and engages with the locking block, the cover plate is fastened at the insertion port.
[0016] Furthermore, the machine body is also equipped with a water tank, a heater, and an anti-backflow pump. The machine body is provided with a water inlet and a water outlet. The water inlet is connected to the water inlet pipe through a first pipe. The water outlet pipe is connected to the water inlet of the water tank through a second pipe. The water tank is connected to the water outlet through a third pipe. The water tank is connected to the heater through a fourth pipe. The heater is connected to the anti-backflow pump through a fifth pipe. The anti-backflow pump is connected to the water tank through a sixth pipe.
[0017] The beneficial effects of this utility model's water dispenser are as follows: An inlet corresponding to the mounting sleeve is provided on the base plate of the machine body. The filter element can be inserted into the mounting sleeve located inside the machine body through this inlet. A locking structure is provided between the mounting sleeve and the filter element. After the filter element is placed in the mounting sleeve, the locking structure securely locks the filter element inside the mounting sleeve, ensuring the stability of the filter element installation and preventing problems such as shaking during use that could affect the water purification effect or cause leakage. The mounting sleeve is equipped with an inlet pipe and an outlet pipe. One end of the inlet pipe is inserted into the inlet of the filter element, and the other end of the outlet pipe is inserted into the outlet of the filter element. Raw water enters the filter element through the inlet pipe and undergoes multi-stage fine filtration and purification treatment inside the filter element, removing impurities, bacteria, viruses, and other harmful substances from the water to obtain pure water. The pure water then flows out of the filter element through the outlet pipe and enters the subsequent heating or cooling system of the water dispenser. The water dispenser heats or cools the purified water after filtration according to the user's needs, thereby providing the user with drinking water at a suitable temperature. When replacing the filter element, users only need to open the inlet from the bottom, release the locking structure, take out the old filter element, insert the new filter element, and lock it, simplifying the operation steps.
[0018] This utility model of a water dispenser provides a convenient channel for the installation and removal of filter cartridges through an inlet on the bottom plate of the machine body. When the filter cartridge needs to be replaced, it can be easily removed from or installed in the installation sleeve through this inlet, without the need for disassembly and installation of complex pipeline connections as required by traditional water dispensers. This simplifies the filter cartridge replacement process, reduces the difficulty of replacement, saves time and labor costs, and makes it convenient for users to replace filter cartridges in a timely manner, ensuring drinking water safety.

It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.
[0030] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".
[0031] like Figure 1 , Figure 2 As shown in the figure, a pipeline machine provided by this utility model includes a body 1, an mounting sleeve 2, and a filter element 3. The mounting sleeve 2 is disposed inside the body 1. An inlet 11 corresponding to the mounting sleeve 2 is opened on the bottom plate of the body 1. The filter element 3 is configured to be inserted into the mounting sleeve 2 through the inlet 11. A locking structure is provided between the mounting sleeve 2 and the filter element 3 to lock the filter element 3 in the mounting sleeve 2. The mounting sleeve 2 is provided with an inlet pipe 21 and an outlet pipe 22. One end of the inlet pipe 21 is inserted into the inlet of the filter element 3, and one end of the outlet pipe 22 is inserted into the outlet of the filter element 3.
[0032] Specifically, the water dispenser mainly consists of a body 1, a mounting sleeve 2, and a filter element 3. The mounting sleeve 2 is located inside the body 1. An inlet 11 corresponding to the position of the mounting sleeve 2 is provided on the bottom plate of the body 1, allowing the filter element 3 to be inserted into the mounting sleeve 2 through this inlet 11, thus achieving the installation and positioning of the filter element 3 inside the body 1. A locking structure is provided between the mounting sleeve 2 and the filter element 3. After the filter element 3 is inserted into the mounting sleeve 2, this locking structure can securely lock the filter element 3 inside the mounting sleeve 2, preventing loosening or displacement during operation and ensuring that the filter element 3 can stably perform its filtration function. The mounting sleeve 2 is equipped with an inlet pipe 21 and an outlet pipe 22. One end of the inlet pipe 21 is inserted into the inlet of the filter element 3, and one end of the outlet pipe 22 is inserted into the outlet of the filter element 3. When the water dispenser starts working, raw water enters the filter element 3 through the inlet pipe 21. After being filtered and purified by the filter element 3, the pure water flows out from the outlet pipe 22 and enters the subsequent heating or cooling system of the water dispenser to meet the user's needs for drinking water at different temperatures.
[0033] In this embodiment, by opening an inlet 11 on the base plate of the machine body 1, the filter element 3 can be directly inserted into the mounting sleeve 2 through the inlet 11. When it is necessary to replace the filter element 3, simply open the inlet 11 to operate, without the need for disassembling complex pipelines as in traditional methods. This greatly simplifies the installation and removal process of the filter element 3, providing convenience for users to replace the filter element 3 and ensuring the timeliness and safety of drinking water. Furthermore, this embodiment integrates the filter element 3 inside the water dispenser, realizing an integrated design of water purification and heating / cooling functions. Compared with the traditional separate setup of water dispensers and water purifiers, this avoids the problem of separate equipment occupying a large space and the complex pipeline connection between the two, effectively saving installation space. It is particularly suitable for use in homes or offices with limited space, improving the applicability of the equipment. Furthermore, the locking structure between the mounting sleeve 2 and the filter element 3 ensures that the filter element 3 can be stably positioned within the mounting sleeve 2 during operation, guaranteeing the connection stability between the filter element 3 and the inlet pipe 21 and outlet pipe 22. This allows raw water to smoothly enter the filter element 3 for filtration and stably delivers the filtered pure water, providing a reliable source of pure water for the subsequent heating or cooling operation of the water dispenser and ensuring the quality of drinking water at a suitable temperature for users.
[0034] Optionally, such as Figure 3 As shown, the mounting sleeve 2 includes a sleeve head 23, a sleeve 24 and a base 25. The sleeve head 23 is connected to the inner wall of the machine body 1 through a connecting piece 26. The base 25 is connected to the bottom plate of the machine body 1 and covers the upper end of the inlet 11. The two ends of the sleeve 24 are respectively fitted onto the inner peripheral wall of the sleeve head 23 and the outer peripheral wall of the base 25.
[0035] Specifically, the mounting sleeve 2 consists of three parts: a sleeve head 23, a sleeve 24, and a base 25. The sleeve head 23 is connected to the inner wall of the body 1 via a connecting piece 26, thus firmly fixing the sleeve head 23 in a specific position inside the body 1, laying the foundation for the installation of subsequent components and the overall structural stability. The base 25 is connected to the bottom plate of the body 1 and completely covers the upper end of the inlet 11 on the bottom plate. The two ends of the sleeve 24 are respectively fitted onto the inner peripheral wall of the sleeve head 23 and the outer peripheral wall of the base 25. Through this fitting method, the sleeve head 23, sleeve 24, and base 25 are connected into a whole, forming a complete mounting sleeve 2 structure, into which the filter element 3 can be installed. When it is necessary to install the filter element 3, the presence of the sleeve 24 provides a guiding channel for the installation of the filter element 3. The filter element 3 enters from the inlet 11 on the base plate and slides up the inner wall of the sleeve 24, which can accurately reach the installation position, ensuring that the filter element 3 is correctly connected with the sleeve 23, base 25 and other components, and facilitating the insertion of the water inlet pipe 21 and the water outlet pipe 22 into the water inlet 16 and the water outlet 17 of the filter element 3, respectively.
[0036] In this optional embodiment, a separate assembly structure of sleeve 23, sleeve 24, and base 25 is adopted. The sleeve 23 is fixed to the inner wall of the body 1 via connecting piece 26, the base 25 is connected to the base plate, and the sleeve 24 is fitted with the sleeve 23 and base 25. Compared to the integral mounting sleeve 2 structure, this design can more rationally distribute stress and improve the overall strength and stability of the mounting sleeve 2. During the operation of the filter element 3, the impact force of water flow on the filter element 3 and the vibration during equipment operation will not easily cause deformation or loosening of the mounting sleeve 2, ensuring the reliability of the connection between the filter element 3 and the mounting sleeve 2, thereby ensuring the stable operation of the water system. Furthermore, when installing the filter element 3, the sleeve 24 provides a clear installation path, reducing installation difficulty; even non-professionals can relatively easily install the filter element 3 correctly. When it is necessary to replace the filter element 3 or maintain the mounting sleeve 2, the sleeve 23, sleeve 24, and base 25 can be operated separately. For example, if the sleeve 24 is damaged, only the sleeve 24 needs to be replaced, instead of replacing the entire mounting sleeve 2, which reduces maintenance costs. At the same time, this split design also makes it easier to clean and inspect the inside of the mounting sleeve 2, improving maintenance efficiency.
[0037] Optionally, such as Figure 4 , Figure 5 As shown, the locking structure includes a groove 231 surrounding the inner wall of the sleeve 23 and a buckle 31 surrounding the outer peripheral wall of the top of the filter element 3. When the top of the filter element 3 is inserted into the mounting sleeve 2 and rotates relative to it, the buckle 31 slides along the sliding path of the groove 231 and engages.
[0038] Specifically, when installing filter element 3, align the top of filter element 3 with inlet 11, and then insert the top of filter element 3 into mounting sleeve 2. At this time, the buckle 31 surrounding the outer periphery of the top of filter element 3 and the groove 231 surrounding the inner side wall of sleeve 23 are in relative positions, but have not yet engaged. After the top of filter element 3 is inserted to a suitable depth, manually rotate filter element 3 relative to mounting sleeve 2. Since both buckle 31 and groove 231 are arranged in a circumferential manner, buckle 31 will slide along the pre-set sliding path of groove 231. As the rotation proceeds, buckle 31 gradually slides to the engagement position of groove 231. At this time, buckle 31 and groove 231 cooperate with each other to form an engagement structure, thereby firmly locking filter element 3 in mounting sleeve 2, ensuring that filter element 3 will not loosen or shift due to water flow impact, equipment vibration, or other factors during operation.
[0039] In this optional embodiment, compared to other complex locking structures, this locking structure can lock the filter element 3 through simple insertion and relative rotation. It eliminates the need for specialized tools or cumbersome disassembly and installation steps. Simply insert the filter element 3 into the mounting sleeve 2 according to the instructions and rotate it a certain angle to complete the installation and locking of the filter element 3. This greatly simplifies the filter element 3 replacement process, improves installation efficiency, and is especially suitable for ordinary users to operate themselves, reducing maintenance costs. The surrounding groove 231 and buckle 31 provide uniform and stable locking force. When the buckle 31 engages in the groove 231, the large contact area between them effectively disperses various forces on the filter element 3, ensuring that the filter element 3 remains fixed in position within the mounting sleeve 2. This prevents the filter element 3 from shaking or shifting during operation, ensuring the sealing of the connection between the filter element 3 and the inlet pipe 21 and outlet pipe 22, preventing leakage, and guaranteeing the normal operation of the water system and the quality of drinking water.
[0040] Optionally, such as Figure 4 , Figure 5 As shown, the sliding path of the slot 231 is provided with an upwardly inclined first guide slope 232, and the end of the buckle 31 is provided with a downwardly inclined second guide slope 32. The second guide slope 32 cooperates with the first guide slope 232 to guide the buckle 31 to slide into the slot 231.
[0041] Specifically, during the process of inserting the top of the filter element 3 into the mounting sleeve 2 and preparing for relative rotation to achieve locking, as the buckle 31 on the top of the filter element 3 gradually approaches the starting end of the sliding path of the groove 231 on the inner side wall of the sleeve head 23, the second guide slope 32 at the end of the buckle 31 will contact the first guide slope 232 at the starting end of the groove 231. Since the first guide slope 232 is inclined upward and the second guide slope 32 is inclined downward, the two cooperate with each other. As the filter element 3 continues to rotate relative to the mounting sleeve 2, the second guide slope 32 will slide along the first guide slope 232. This interaction between the slopes generates a guiding force, allowing the buckle 31 to smoothly slide into the sliding path of the groove 231 without precisely aligning with the entrance of the groove 231, thereby guiding the filter element 3 to complete the subsequent snap-fit locking operation.
[0042] In this optional embodiment, in actual operation, it is difficult for users to ensure that the buckle 31 of the filter element 3 is perfectly aligned with the inlet of the slot 231. By setting the first guide slope 232 and the second guide slope 32, an automatic guiding function is provided for the buckle 31 to slide into the slot 231. Even if there is a certain initial deviation between the buckle 31 and the inlet of the slot 231, it can smoothly enter the slot 231 under the guidance of the slope, which greatly reduces the alignment accuracy requirement for the installation of the filter element 3, making the installation process simpler and faster. Even users without professional operating experience can easily complete the installation of the filter element 3. Due to the existence of the guide slope, the time spent on repeated adjustments and attempts caused by the buckle 31 not being able to accurately enter the slot 231 is reduced. When installing the filter element 3, the user only needs to roughly insert the top of the filter element 3 into the installation sleeve 2, and then perform a simple rotation operation. The buckle 31 can quickly slide into the slot 231 under the guidance of the guide slope, thereby significantly improving the installation efficiency of the filter element 3 and saving the user's time and effort. Without the guidance of the guide ramp, the latch 31 may violently collide and rub against the edge of the slot 231 during forced insertion into the slot 231, causing wear, scratches, or even damage to the surfaces of both the latch 31 and the slot 231, affecting the reliability and service life of the locking structure. The guide ramp allows the latch 31 to slide smoothly and steadily into the slot 231, avoiding such violent collisions and friction, reducing wear between components, extending the service life of both the slot 231 and the latch 31, and lowering equipment maintenance costs.
[0043] Optionally, such as Figure 4 , Figure 5 As shown, the sliding path end of the slot 231 is provided with a protrusion 233, and the buckle 31 is provided with a groove 33 on the side near the second guide slope 32. When the buckle 31 slides to the end of the slot 231, the protrusion 233 and the groove 33 engage and limit the position.
[0044] Specifically, when the top of the filter element 3 is inserted into the mounting sleeve 2 and rotates relative to it, the buckle 31 moves along the sliding path of the slot 231 under the guidance of the first and second guide slopes 32 until it reaches the end of the sliding path of the slot 231. When the buckle 31 slides to the end of the slot 231, the protrusion 233 at the end of the slot 231 will precisely align with the groove 33 on the side of the buckle 31 near the second guide slope 32. Since the shape and size of the protrusion 233 and the groove 33 match each other, the protrusion 233 will embed into the groove 33, forming a snap-fit limiting structure. This snap-fit limiting can effectively prevent the buckle 31 from continuing to slide along the slot 231, thereby firmly locking the filter element 3 in the mounting sleeve 2 and preventing the filter element 3 from loosening or rotating in the opposite direction due to external forces (such as water flow impact, equipment vibration, etc.) during operation.
[0045] In this optional embodiment, compared to relying solely on the friction and simple shape matching between the buckle 31 and the groove 231 to lock the filter element 3, the snap-fit limiting structure of the protrusion 233 and the groove 33 provides additional mechanical locking. Even in the event of significant vibration or external impact during use, the tight snap-fit between the protrusion 233 and the groove 33 ensures that the filter element 3 will not easily come out of the mounting sleeve 2 or shift, greatly improving the stability and reliability of the filter element 3 installation and ensuring the normal operation of the water system of the pipeline machine. When the buckle 31 slides to the end of the groove 231 and the protrusion 233 snaps into place with the groove 33, a distinct "click" sound or a certain tactile feedback (such as a sudden increase in rotational resistance) will be emitted. This clear feedback mechanism allows the user to intuitively judge whether the filter element 3 has been installed and locked in place, avoiding problems such as water leakage and malfunction of the filter element 3 due to improper installation, thus improving the user experience.
[0046] Optionally, such as Figure 4 , Figure 5 As shown, the end of the buckle 31 away from the second guide slope 32 is provided with a radially extending first abutment block 34. When the protrusion 233 is engaged in the groove 33, the end of the first guide slope 232 abuts against the first abutment block 34.
[0047] And / or,
[0048] The end of the slot 231 away from the first guide slope 232 is provided with a radially extending second abutment block 234. When the protrusion 233 is engaged in the groove 33, the end of the second guide slope 32 abuts against the second abutment block 234.
[0049] Specifically, during the installation of the filter element 3, the buckle 31 slides along the groove 231 under the guidance of the guide slope. After the protrusion 233 engages with the groove 33 to achieve locking and limiting, the first abutment block 34, which extends radially away from the second guide slope 32 of the buckle 31, abuts against the end of the first guide slope 232, and / or, the second abutment block 234, which extends radially away from the first guide slope 232 of the groove 231, abuts against the end of the second guide slope 32 of the buckle 31. At this time, the first abutment block 34 and the end of the first guide slope 232 cooperate with each other, and / or, the second abutment block 234 and the end of the second guide slope 32 cooperate with each other, restricting the further movement of the buckle 31 in the groove 231 from multiple directions. This prevents the buckle 31 from continuing to move towards the end of the sliding path of the groove 231, and also prevents the buckle 31 from retracting towards the starting end, thereby firmly locking the filter element 3 in the mounting sleeve 2.
[0050] In this optional embodiment, compared with simply relying on the engagement of the protrusion 233 and the groove 33, the engagement of the first abutting block 34 with the end of the first guide slope 232 and / or the engagement of the second abutting block 234 with the end of the second guide slope 32 provides additional limiting effect, which together constitutes a multi-level locking and limiting system, making the overall performance of the locking structure more stable and reliable, and able to adapt to various complex working environments. This greatly enhances the locking stability of the filter element 3 in the mounting sleeve 2, effectively resists the loosening or displacement of the filter element 3 caused by external factors (such as water flow impact, equipment vibration, etc.), and ensures the normal operation of the pipeline machine water system.
[0051] Optionally, such as Figure 3 , Figure 6 As shown, the inner peripheral wall of the top end of the sleeve 24 is provided with a first abutting platform 241 for abutting against the bottom of the sleeve head 23; the outer peripheral wall of the bottom end of the sleeve 24 is provided with a second abutting platform 242 for abutting against the top end of the base 25; the bottom end of the base 25 is connected to the inner peripheral wall of the insertion port 11.
[0052] Specifically, when the mounting sleeve 2 is installed inside the body 1, the sleeve 24 is first fixed to the inner wall of the body 1 by the connecting piece 26. Then, the bottom end of the base 25 is connected to the inner peripheral wall of the inlet 11. Then, the first abutting platform 241 of the sleeve 24 abuts against the bottom of the sleeve head 23, which limits the sleeve head 23 from above. Then, the second abutting platform 242 of the outer peripheral wall of the bottom end of the sleeve 24 abuts against the top of the base 25, which limits the sleeve 24 from below and prevents the sleeve 24 from moving further down inside the base 25, thus completing the installation and positioning of the mounting sleeve 2.
[0053] In this optional embodiment, the first abutment platform 241 and the second abutment platform 242 respectively axially limit the sleeve head 23 and the sleeve 24, ensuring that the sleeve 24 and the sleeve head 23, as well as the sleeve 24, are accurately positioned within the base 25. The first abutment platform 241, the second abutment platform 242, and the connection structure between the base 25 and the inlet 11 cooperate to form a stable mounting sleeve 2 structure, ensuring the stability of the filter element 3 placement and thus guaranteeing the long-term stable operation of the equipment.
[0054] Optionally, such as Figure 1 , Figure 3 , Figure 7 As shown, the body 1 has a cover plate 12 at the inlet 11, and a handle 121 is provided on the outside of the cover plate 12. The base 25 has a third abutment platform 253 on its inner peripheral wall at the inlet 11. When the cover plate 12 is closed, the outer peripheral edge of the cover plate 12 abuts against the third abutment platform 253. A fastening structure is provided between the inner peripheral wall of the base 25 and the outer peripheral wall of the cover plate 12 to fasten the cover plate 12 to the inlet 11.
[0055] Specifically, the body 1 has a cover plate 12 at the inlet 11. When the cover plate 12 is closed, the third abutment platform 253 provides a clear axial positioning reference for the cover plate 12. The outer periphery of the cover plate 12 abuts against the third abutment platform 253, thereby limiting further axial movement of the cover plate 12 and ensuring that the cover plate 12 is accurately and stably installed at the inlet 11. The fastening structure between the inner peripheral wall of the base 25 and the outer peripheral wall of the cover plate 12 tightly connects the cover plate 12 and the base 25 together through mechanical force. When the cover plate 12 is closed and abuts against the third abutment platform 253, the fastening structure functions to prevent the cover plate 12 from rotating circumferentially and loosening when subjected to external force, thus firmly fixing the cover plate 12 at the inlet 11 and forming a sealed or protective space.
[0056] In this optional embodiment, the presence of the third abutment platform 253 ensures a highly certain installation position of the cover plate 12 at the inlet 11. Operators only need to place the cover plate 12 into the inlet 11 and allow its outer periphery to abut against the third abutment platform 253 to quickly complete the initial positioning of the cover plate 12, eliminating the need for complex measurement and adjustment processes and greatly improving installation efficiency. The fastening structure effectively resists the influence of various external forces on the cover plate 12, preventing it from loosening or falling off during use, thus ensuring the stability and safety of the equipment during long-term operation.
[0057] Optionally, such as Figure 3 , Figure 7 As shown, the fastening structure includes a positioning groove 251 surrounding the inner peripheral wall of the base 25 and a positioning block 122 located on the outer peripheral wall of the cover plate 12. The positioning groove 251 is provided with a locking block 252. When the positioning block 122 rotates into the positioning groove 251 and engages with the locking block 252, the cover plate 12 is fastened at the inlet 11.
[0058] Specifically, when installing the cover plate 12, align the positioning block 122 on the outer peripheral wall of the cover plate 12 with the positioning groove 251 on the inner peripheral wall of the base 25, and allow the positioning block 122 to enter the positioning groove 251. The positioning groove 251 provides a clear guide and initial positioning space for the positioning block 122, ensuring that the approximate position of the cover plate 12 at the inlet 11 is accurate, avoiding large radial and axial deviations of the cover plate 12, and preparing for subsequent fastening operations. After the positioning block 122 is fully inserted into the positioning groove 251, rotate the cover plate 12 to move the positioning block 122 within the positioning groove 251. As the cover plate 12 rotates, the positioning block 122 gradually approaches the locking block 252 within the positioning groove 251. When the positioning block 122 rotates to a specific position, it engages with the locking block 252. The locking block 252 acts as a stop for the positioning block 122, thereby securing the cover plate 12 at the inlet 11 and preventing the cover plate 12 from loosening or detaching due to external force.
[0059] In this optional embodiment, the engagement of the positioning groove 251 and the positioning block 122 precisely limits the position of the cover plate 12 at the inlet 11, ensuring the fitting accuracy between the cover plate 12 and the base 25 and other components after installation. This avoids problems such as poor sealing and component interference caused by installation deviations, thereby improving the overall performance and reliability of the equipment. Installers only need to place the positioning block 122 into the positioning groove 251 and then rotate the cover plate 12 to complete the fastening operation. No complex tools or professional skills are required, greatly reducing installation difficulty and operation time, and improving installation efficiency. The engagement between the locking block 252 and the positioning block 122 provides reliable fastening force, effectively resisting the influence of various external forces on the cover plate 12, preventing the cover plate 12 from loosening or falling off during equipment operation, and ensuring long-term stable operation of the equipment.
[0060] Optionally, such as Figure 1 As shown, the machine body 1 is also equipped with a water tank 13, a heater 14, and an anti-backflow pump 15. The machine body 1 is equipped with a water inlet 16 and a water outlet. The water inlet 16 is connected to the water inlet pipe 21 through a first pipe. The water outlet pipe 22 is connected to the water inlet 16 of the water tank 13 through a second pipe. The water tank 13 is connected to the water outlet through a third pipe. The water tank 13 is connected to the heater 14 through a fourth pipe. The heater 14 is connected to the anti-backflow pump 15 through a fifth pipe. The anti-backflow pump 15 is connected to the water tank 13 through a sixth pipe.
[0061] Specifically, external water enters through inlet 16 on the main body 1, flows through the first pipe to inlet pipe 21, and then enters filter element 3. After being filtered and purified by filter element 3, the pure water flows out from outlet pipe 22. After flowing out from outlet pipe 22, the water enters inlet 16 of water tank 13 through the second pipe, and water tank 13 begins to store water, serving as a reserve water source for subsequent cold water supply and hot water preparation. The cold water in water tank 13 can be directly transported to outlet through the third pipe. When the user needs cold water, they can open the outlet valve to obtain the cold water stored in water tank 13. The water in water tank 13 enters heater 14 through the fourth pipe, where heater 14 heats the water, turning the cold water into hot water. The heated hot water flows into anti-backflow pump 15 through the fifth pipe, which provides power to transport the hot water back to water tank 13 through the sixth pipe. At this point, water tank 13 contains both cold and hot water, serving to mix and store water at different temperatures. When a user needs hot water, the heated and mixed hot water in water tank 13 is delivered to the outlet through the third pipeline, and the user can use the hot water by opening the outlet valve. The anti-backflow pump 15 plays a crucial role in the entire water circulation system. It not only provides power for hot water delivery but also prevents backflow. For example, when heater 14 stops heating or system pressure fluctuates, the anti-backflow pump 15 can prevent hot water from flowing back from heater 14 or water tank 13 into other pipelines, ensuring the normal operation of the water circuit and the stable direction of water flow.
[0062] In this optional embodiment, components such as the water tank 13, heater 14, and anti-backflow pump 15 are integrated into the main body 1. Through a reasonable water circuit connection, both cold and hot water supply functions are realized. Users do not need to install separate cold and hot water supply equipment; one main body 1 can meet different water needs, improving ease of use. The anti-backflow pump 15 effectively prevents water backflow, avoiding problems such as abnormal water pressure and equipment damage caused by backflow, improving the stability and reliability of the entire water circuit system, and extending the service life of the equipment.
