Description

Technical Field

[0001] The utility model relates to the technical field of water supply, in particular to a water inlet device and water supply equipment. Background Art

[0002] Water supply equipment such as water heaters and direct drinking water machines have certain requirements for water quality. Although the tap water supplied to ordinary households has undergone preliminary purification in the water plant, the calcium and magnesium ions, carbonate ions, etc. contained in the water will precipitate and form scale after heating, which is not conducive to the long-term use of water supply equipment.

[0003] In order to reduce the probability of scale formation inside water heaters, etc., the prior art provides a filtering and anti-scaling valve, which includes a main valve body and an anti-scaling valve body installed on the main valve body, the main valve body having a water inlet interface, a filter chamber and a water outlet interface connected in sequence; the anti-scaling valve body is inserted into the filter chamber, and a scale-inhibiting chamber with a bottom opening is provided in the anti-scaling valve body, a scale inhibitor is provided in the scale-inhibiting chamber, and the outer wall of the anti-scaling valve body is provided with water inlet and outlet holes connecting the scale-inhibiting chamber and the filter chamber.

[0004] In the filter scale prevention valve provided by the prior art, after the water flows into the filter scale prevention valve through the water inlet interface, the water flows through the filter chamber, the scale prevention chamber and the water outlet interface in sequence, so that when the water flows through the scale prevention chamber, the scale inhibitor can be released into the water, reducing the probability of scaling of substances in the water. However, since the scale prevention chamber, the filter chamber, the water inlet interface and the water outlet interface are arranged opposite to each other, the water flows only through the bottom position of the scale prevention valve body, so that only the scale inhibitor arranged at the bottom of the scale prevention chamber produces a water treatment reaction, and the rest can only be released in a small amount through immersion, resulting in a low release efficiency of the scale inhibitor, and the scale prevention efficiency is difficult to meet the requirements.

[0043] Embodiment 1

[0044] The utility model provides a water inlet device, which can be applied to water supply equipment to process the inlet water quality of the water supply equipment, reduce the probability of scaling inside the water supply equipment, and improve the use reliability of the water supply equipment.

[0045] like Figures 1 to 4 As shown, in this embodiment, the water inlet device includes a water inlet connector 1 and a water treatment component. The water inlet connector 1 has a water inlet 111, a mounting cavity 132 and a water outlet 121 connected in sequence; the water treatment component includes a shell 2 and a water guide 3, the shell 2 has a receiving cavity 25, the first end of the shell 2 is sealed and inserted in the mounting cavity 132, and the receiving cavity 25 is used to receive water treatment substances; the water guide 3 is arranged in the receiving cavity 25 and separates the receiving cavity 25 into a water inlet channel 251a and a water outlet channel 251b, the water inlet channel 251a and the water outlet channel 251b are connected at one end away from the mounting cavity 132, the first end outer wall of the shell 2 is provided with a water inlet connecting hole 231a connecting the water inlet 111 and the water inlet channel 251a, and the first end outer wall of the shell 2 is provided with a water outlet connecting hole 231b connecting the water outlet 121 and the water outlet channel 251b.

[0046] The water inlet device provided in the present embodiment has a water guide member 3 that divides the accommodating chamber 25 circumferentially into a water inlet channel 251a and a water outlet channel 251b, so that when water flows in from the water inlet 111, it will flow through the water inlet 111, the water inlet connecting hole 231a, the water inlet channel 251a, the water outlet channel 251b and the water outlet connecting hole 231b in sequence and flow out from the water outlet 121, thereby increasing the flow path of the water flow in the accommodating chamber 25, thereby increasing the residence time of the water in the accommodating chamber 25 and increasing the contact area between the water flow and the water treatment material, so that the water treatment material in the water inlet channel 251a and the water outlet channel 251b can be dissolved under the flushing action of the water flow, thereby increasing the amount of water treatment material participating in water treatment in the accommodating chamber 25, thereby improving the water treatment effect of the water inlet device.

[0047] It is worth noting that the water treatment material can be a scale inhibitor or other granular material that can treat water, and the specific type and cost of the water treatment material can be set according to existing technology and actual needs. The utility model does not limit the specific structure of the water treatment material.

[0048] In one embodiment, the shell 2 is an elongated strip structure extending along the first direction, so as to increase the size of the accommodating chamber 25 while keeping the size of the water inlet connector 1 unchanged, thereby increasing the amount of water treatment material that can be accommodated in the accommodating chamber 25, reducing the frequency of replacement of the water treatment component, and increasing the single use time of the water treatment component.

[0049] like Figure 2 , Figure 3 and Figure 6 As shown, the water inlet joint 1 includes an inlet pipe portion 11, an outlet pipe portion 12 and a mounting portion 13 that are connected to each other. The port of the inlet pipe portion 11 forms a water inlet 111, and the port of the outlet pipe portion 12 forms a water outlet 121. The mounting portion 13 is located between the inlet pipe portion 11 and the outlet pipe portion 12, and the inner cavity forms a mounting cavity 132. The mounting cavity 132 has a mounting port, and the housing 2 is inserted into the mounting cavity 132 through the mounting port, and the housing 2 is detachably connected to the mounting portion 13 to facilitate the replacement of the water treatment component. The arrangement of the inlet pipe portion 11 and the outlet pipe portion 12 facilitates the connection of the water inlet device to the water supply pipeline.

[0050] The axes of the water inlet pipe portion 11 and the water outlet pipe portion 12 are both perpendicular to the first direction to reduce the interference between the water treatment component and the water inlet pipe portion 11 and the water outlet pipe portion 12. In one embodiment, the water inlet pipe portion 11 and the water outlet pipe portion 12 are respectively arranged on opposite sides of the housing 2, that is, the axes of the water inlet pipe portion 11 and the water outlet pipe portion 12 are coaxially arranged. In other embodiments, the axes of the water inlet pipe portion 11 and the water outlet pipe portion 12 can also be arranged perpendicularly. The position between the water inlet pipe portion 11 and the water outlet pipe portion 12 can be specifically set according to the layout of the water supply pipeline to be installed, and the utility model does not limit this.

[0051] In order to improve the connection convenience between the water inlet connector 1 and the housing 2, one end of the mounting portion 13 protrudes from the outer side walls of the water inlet pipe portion 11 and the water outlet pipe portion 12 to form a mounting pipe portion 131, and the port of the mounting pipe portion 131 forms a mounting port. The first end of the housing 2 is inserted into the mounting pipe portion 131 and is detachably connected to the mounting pipe portion 131, so that the connection structure of the mounting portion 13 and the housing 2 is located outside the installation cavity 132 to avoid the connection structure of the housing 2 and the mounting portion 13 from hindering the flow of water.

[0052] In one embodiment, the inner wall of the mounting tube 131 is provided with an internal thread, the housing 2 has a threaded pipe section 22, and an external thread is provided on the outer wall of the threaded pipe section 22. The threaded pipe section 22 is screwed on the inner wall of the mounting tube 131, so that the water treatment component can be inserted into the water inlet connector 1 by screwing, thereby improving the installation convenience and stability of the housing 2 on the water inlet connector 1, and improving the disassembly and assembly efficiency of the water treatment component; at the same time, the housing 2 is threadedly connected to the inner wall of the mounting tube 131, which is also conducive to achieving the sealing between the mounting tube 131 and the housing 2.

[0053] In order to prevent water from flowing out from the connection position between the water inlet connector 1 and the housing 2, in one embodiment, a sealing ring 4 is sandwiched between the outer peripheral wall of the housing 2 and the mounting pipe portion 131 to ensure the sealing of the housing 2 and the water inlet connector 1 after connection. The sealing ring 4 is preferably located on the side of the threaded pipe section 22 away from the mounting cavity 132. In one embodiment, a sealing groove 26 is provided on the outer side wall of the housing 2, and the sealing ring 4 is installed in the sealing groove 26, so that the sealing ring 4 can be plugged in and out of the water inlet connector 1 along with the housing 2, thereby improving the assembly efficiency and assembly accuracy of the sealing ring 4.

[0054] In order to limit the depth of the housing 2 inserted into the installation cavity 132, in one embodiment, the housing 2 includes a main housing portion 21, and a positioning ring portion 24 is protruded outwardly on the outer wall of the main housing portion 21. The positioning ring portion 24 abuts against the open end face of the installation port, that is, the positioning ring portion 24 abuts against the end face of the installation pipe portion 131, so as to provide positioning and limiting for the installation of the housing 2 on the water inlet connector 1, thereby improving the assembly efficiency and assembly reliability of the water inlet device. The sealing groove 26 is arranged between the threaded pipe section 22 and the positioning ring portion 24, so that the sealing groove 26 can also be a back-cut groove of the thread processing.

[0055] like Figure 3 and Figure 4 As shown, in order to reduce the probability of large impurities such as iron filings, mud and sand in the water entering the accommodating chamber 25, in one embodiment, a filter screen 5 is sleeved on the outside of the first end of the shell 2, and the filter screen 5 is sleeved on the outside of the first end of the shell 2, and the filter screen 5 covers all the openings on the outer wall of the first end of the shell 2. The arrangement of the filter screen 5 requires that the water flowing from the installation cavity 132 to the accommodating chamber 25 needs to pass through the filter screen 5 before flowing to the openings on the shell 2, so that the filter screen 5 can filter large impurities in the tap water, thereby preventing large impurities from flowing into the accommodating chamber 25 and causing impurities to accumulate in the accommodating chamber 25, and also preventing large impurities from flowing out of the water outlet 121 and flowing into the water supply equipment, further improving the water treatment effect of the water inlet device.

[0056] In one embodiment, a positioning step surface is provided on the outer peripheral wall of the shell 2, and the positioning step surface is arranged toward the bottom of the installation cavity 132. One end of the filter screen 5 abuts against the bottom of the installation cavity 132, and the other end of the filter screen 5 abuts against the positioning step surface, thereby realizing the installation limit of the filter screen 5 on the shell 2, and preventing the filter screen 5 from moving relative to the shell 2 along the first direction.

[0057] like Figure 3 and Figure 6 As shown, specifically, the shell 2 includes a water pipe portion 23 coaxially connected to the threaded pipe segment 22, the outer diameter of the water pipe portion 23 is smaller than the outer diameter of the threaded pipe segment 22, the above-mentioned positioning step surface is formed between the water pipe portion 23 and the threaded pipe segment 22, a plurality of water holes 231 are opened on the water pipe portion 23, the water holes 231 include a water inlet connecting hole 231a and a water outlet connecting hole 231b, and the filter net 5 is sleeved in the water pipe portion 23.

[0058] Furthermore, the outer circumferential surface of the filter screen 5 abuts against the cavity wall of the installation cavity 132, and the inner circumferential surface of the filter screen 5 fits against the outer surface of the water pipe portion 23, thereby clamping the filter screen 5 between the cavity wall of the installation cavity 132 and the shell 2 to prevent the filter screen 5 from shaking relative to the shell 2, thereby improving the setting stability and reliability of the filter screen 5.

[0059] In one embodiment, the water inlet device further includes a magnet 6, which is located in the accommodating cavity 25, and is sandwiched between the water guide 3 and the bottom of the installation cavity 132, and the magnet 6 is partially exposed in the water inlet channel 251a and the water outlet channel 251b. The magnet 6 can adsorb metal impurities such as rust in the water to reduce the amount of impurities in the water, thereby further improving the water treatment effect; at the same time, the magnet 6 is arranged between the bottom of the installation cavity 132 and the water guide 3, which can ensure the stability of the arrangement of the magnet 6.

[0060] like Figure 3 and Figure 7 As shown, in order to improve the installation convenience of the magnet 6, in one embodiment, the first end surface of the water guide 3 is provided with an installation groove 34, and the magnet 6 is installed in the installation groove 34 to realize the installation positioning of the magnet 6 relative to the water guide 3, and to prevent the magnet 6 from being offset under the impact of the water flow. Further, the magnet 6 preferably adopts a disc-shaped structure to match the cylindrical accommodating cavity 25. The outer diameter of the magnet 6 is greater than 0.8 times the outer diameter of the accommodating cavity 25, so as to increase the contact area between the magnet 6 and the water flow in the water inlet channel 251a and the water outlet channel 251b, thereby improving the ability of the magnet 6 to adsorb impurities in the water.

[0061] like Figure 4 and Figure 5 As shown, in one embodiment, at least two water inlet channels 251a are provided along the circumference of the accommodating chamber 25, and the other end of any water inlet channel 251a away from the installation chamber 132 is connected to the water outlet channel 251b; and / or, at least two water outlet channels 251b are provided along the circumference of the accommodating chamber 25, and the end of any water outlet channel 251b away from the installation chamber 132 is connected to the water inlet channel 251a. This arrangement can further divert the water flow in the accommodating chamber 25, thereby further increasing the contact area between the water flow and the water treatment substance in the accommodating chamber 25, which is conducive to ensuring that most of the water treatment substances in the accommodating chamber 25 can participate in the reaction, and improving the water treatment effect of the water inlet device.

[0062] In one embodiment, the water guide 3 includes a water guide body 31, which includes at least two diverter parts 311, all of which are sequentially arranged along the circumference of the accommodating cavity 25, and the first ends of all of the diverter parts 311 are intersecting and connected, and the second ends of all of the diverter parts 311 are in contact with the cavity wall of the accommodating cavity 25, and a diverter channel 251 is formed between two adjacent diverter parts 311, and the diverter channel 251 connected to the water inlet 111 is the water inlet channel 251a, and the diverter channel 251 connected to the water outlet 121 is the water outlet channel 251b. The structure of this water guide 3 is simple, which is conducive to the molding of the water inlet channel 251a and the water outlet channel 251b, and can simplify the setting of the entire water inlet device.

[0063] In other embodiments, the water guide member 3 may also be a columnar structure, and a water inlet channel 251a and a water outlet channel 251b are formed on the outer side wall of the columnar structure.

[0064] In one embodiment, two water inlet channels 251a and two water outlet channels 251b are provided, that is, four diverter portions 311 are provided, and the four diverter portions 311 are connected to form a structure with a "cross" cross section, so as to simplify the structure of the water guide 3, and facilitate ensuring that the water inlet channel 251a is connected to the water inlet 111 while the water inlet channel 251a is not directly connected to the water outlet 121. In other embodiments, the number of water inlet channels 251a and the number of water outlet channels 251b can also be set in other ways, for example, one water inlet channel 251a is provided and two or more water outlet channels 251b are provided; or one water outlet channel 251b is provided and two or more water inlet channels 251a are provided.

[0065] Furthermore, two of the diverter portions 311 are perpendicular to the water inlet direction of the water inlet 111, and the other two diverter portions 311 are parallel to the water inlet direction, so that the water inlet channel 251a located on one side of the two diverter portions 311 can face the water inlet 111, and the water outlet channel 251b located on the other opposite side of the two diverter portions 311 can be arranged facing the water outlet 121.

[0066] To ensure that the water inlet channel 251a can only be connected to the water outlet 121 through the water outlet channel 251b, in the present embodiment, each water inlet channel 251a and water outlet channel 251b are respectively provided with a water hole group, each water hole group includes at least one water hole 231, and the water inlet channel 251a and the water outlet channel 251b are connected to the installation cavity 132 through the water holes 231 in the corresponding water hole groups, which is beneficial to control the water flow direction of the water inlet channel 251a and the water outlet channel 251b.

[0067] In one embodiment, each water hole group includes a plurality of water holes 231 spaced apart along the first direction, and the water holes 231 are long holes extending along the circumference of the accommodating cavity 25 to increase the water flow rate entering the corresponding water inlet channel 251a or water outlet channel 251b. In other embodiments, the water hole group may also include a plurality of water holes 231 spaced apart along the circumference of the accommodating cavity 25, and the water holes 231 are long holes extending along the first direction.

[0068] It is worth noting that, among the water holes 231, the one communicating with the water inlet channel 251a is the water inlet communicating hole 231a, and the one communicating with the water outlet channel 251b is the water outlet communicating hole 231b.

[0069] In order to ensure the installation stability of the water guide member 3 in the accommodating cavity 25, the water guide member 3 has a limiting component 32, one end of the limiting component 32 is connected to the end of the water guide body 31 away from the bottom of the installation cavity 132, the other end of the limiting component 32 is in contact with the bottom of the accommodating cavity 25, a communication port is formed between the limiting component 32 and the circumferential cavity wall of the accommodating cavity 25, and the water inlet channel 251a and the water outlet channel 251b are connected through the communication port. The setting of the limiting component 32 allows the water guide member 3 to be sandwiched between the cavity bottom of the accommodating cavity 25 and the cavity bottom of the installation cavity 132, so as to prevent the water guide member 3 from moving relative to the housing 2 along the first direction.

[0070] The limiting component 32 is a rod-shaped structure extending along the first direction, and the first end of the limiting component 32 is connected to the intersection of all the diversion parts 311, that is, the limiting component 32 is arranged along the central axis of the accommodating cavity 25 to better ensure the stability of the force when the limiting component 32 abuts against the shell 2.

[0071] like Figures 3 to 5 As shown, in order to prevent the water guide member 3 from rotating relative to the shell 2 and causing the water inlet channel 251a and the water outlet channel 251b to be misaligned with the corresponding water hole 231, a stop structure is provided between the water guide member 3 and the inner wall of the shell 2, which limits the rotation of the water guide member 3 relative to the shell 2.

[0072] In one embodiment, the anti-rotation structure includes an anti-rotation groove 27 provided on the wall of the accommodating cavity 25 and an anti-rotation protrusion 33 provided at the end of the diverter 311, and the anti-rotation protrusion 33 is inserted into the anti-rotation groove 27. The anti-rotation protrusion 33 and the anti-rotation groove 27 are provided in a one-to-one correspondence with the diverter 311, thereby avoiding the problem that the force-bearing position of the water guide 3 is easily deformed and damaged due to the single-point force, thereby extending the service life of the water guide 3.

[0073] In other embodiments, the anti-rotation structure can also be arranged between the limiting component 32 and the bottom of the accommodating cavity 25. For example, the cross-sectional area of ​​the limiting component 32 can be set to a non-circular cross-section, and a positioning groove is provided at the bottom of the accommodating cavity 25. The limiting component 32 is inserted into the positioning groove, and the shape of the positioning groove is adapted to the cross-sectional shape of the limiting component 32.

[0074] In one embodiment, the first end of the housing 2 is rotatably mounted in the mounting cavity 132, thereby adjusting the relative position of the diverter channel 251 and the water inlet 111, thereby enabling part of the water inlet channel 251a to communicate with the water inlet 111 and communicate with the water outlet 121 only through the water outlet channel 251b, while another part of the diverter channel 251 can be simultaneously connected with the water inlet 111 and the water outlet 121 through the water hole 231, so that part of the water flow can flow directly to the water outlet 121 through the diverter channel 251, thereby reducing the water flow resistance. That is, when a plurality of diverter channels 251 are provided, the number of the water inlet channel 251a and the water outlet channel 251b can be adjusted by rotating the housing 2 relative to the water inlet connector 1, thereby changing the water flow resistance and adjusting the treatment effect of the water treatment substance on the water.

[0075] The present embodiment further provides a water supply device, comprising the above-mentioned water inlet device. The water supply device provided in the present embodiment can improve the water quality of water entering the water supply device by adopting the above-mentioned water inlet device, thereby reducing the probability of scaling inside the water supply device, improving the reliability of the water supply device, and reducing the frequency of maintenance of the water supply device.

[0076] Embodiment 2

[0077] This embodiment provides a water inlet device and a water supply device including the water inlet device. The basic structure of the water inlet device provided in this embodiment is the same as that of the first embodiment, and only the arrangement of the water guide 3 is different. This embodiment will not repeat the same contents as the first embodiment.

[0078] like Figure 8 As shown, in this embodiment, two diverter parts 311 are provided, and the two diverter parts 311 divide the accommodating chamber 25 into a water inlet channel 251a and a water outlet channel 251b. The water inlet channel 251a is directly connected to the water inlet 111 through the water inlet communication hole 231a, and the water outlet channel 251b is directly connected to the water outlet 121 through the water outlet communication hole 231b. This arrangement has a relatively simple structure and low cost.

[0079] In this embodiment, the two flow splitters 311 are symmetrically arranged at 180°, that is, the two flow splitters 311 are connected to form an integrated plate-like structure. In other embodiments, the two flow splitters 311 may also be arranged at an angle.

[0080] In this embodiment, two groups of water inlet connecting holes 231a are arranged at intervals along the circumference of the accommodating cavity 25, and each group includes a plurality of water inlet connecting holes 231a arranged at intervals along the extension direction of the accommodating cavity 25. The interval positions of the two groups of water inlet connecting holes 231a are arranged opposite to the water inlet 111, so that the water flow entering from the water inlet 111 can be diverted to the two groups of water inlet connecting holes 231a.

[0081] Two groups of water outlet communication holes 231 b are arranged at intervals along the circumference of the accommodating chamber 25 , and each group includes a plurality of water outlet communication holes 231 b arranged at intervals along the extension direction of the accommodating chamber 25 to reduce water flow resistance and increase water inlet flow.

[0082] Embodiment 3

[0083] This embodiment provides a water inlet device and a water supply device including the water inlet device. The basic structure of the water inlet device provided in this embodiment is the same as that of the first embodiment, and only the arrangement of the water guide 3 is different. This embodiment will not repeat the same contents as the first embodiment.

[0084] like Fig. 9 As shown, in this embodiment, the water guide 3 divides the accommodating chamber 25 into a plurality of diversion channels 251 along the circumferential direction, part of the diversion channels 251 are water inlet channels 251a, part of the diversion channels 251 are water outlet channels 251b, and at least one diversion channel 251 is a straight-through channel 251c. The outer peripheral wall of the shell 2 is provided with a straight-through communication hole 231c that connects the water inlet 111, the straight-through channel 251c and the water outlet 121 in sequence.

[0085] By setting up the straight channel 251c, part of the water flow entering from the water inlet 111 can flow directly to the water outlet 121 through the straight connecting hole 231c and the straight channel 251c, reducing the flow path of this part of the water flow in the accommodating chamber 25, thereby reducing the flow resistance of the water flow and increasing the water flow rate.

[0086] In this embodiment, one water inlet channel 251a and one water outlet channel 251b are respectively provided, and two groups of straight-through communication holes 231c are arranged at intervals along the circumference of the water containing cavity, and each group includes a plurality of straight-through communication holes 231c arranged at intervals along the axial direction of the containing cavity 25. One group of straight-through communication holes 231c is connected to the water inlet 111 and the direct-flow channel, and the other group of straight-through communication holes 231c is connected to the water outlet 121 and the direct-flow channel, so as to reduce the extension length of a single straight-through communication hole 231c in the circumferential direction of the shell 2 while ensuring that the direct-flow channel is connected to both the water inlet 111 and the water outlet 121, thereby ensuring the overall structural strength and rigidity of the shell 2.

[0087] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
