Description

Technical Field

[0001] This application relates to the field of water purification devices, and in particular to a faucet water purifier. Background Art

[0002] The main problems existing in tap water are as follows: First, there are various chlorination disinfection by-products, heavy metals, and calcium sulfite that are harmful to the human body; second, due to the lack of regular pipeline cleaning, algae are likely to grow in the water delivery pipeline, seriously affecting the water quality and causing secondary pollution during transportation. Therefore, in order to obtain better water quality, using a water purifier to purify water is the first choice for people.

[0003] In the related art, a faucet water purifier is disclosed, which has only one water flow channel. Tap water flows in from the water inlet, then flows through the filter element, and finally flows out from the water outlet. During the use of the faucet water purifier, tap water must pass through the filter element and then flow out after purification; therefore, when the water purifier is used without the need for purified water, the filtering efficiency of the filter element is wasted, thereby reducing the service life of the faucet water purifier. Summary of the Utility Model

[0004] In order to extend the service life of the faucet water purifier, this application provides a faucet water purifier.

[0005] The faucet water purifier provided by this application adopts the following technical solutions:

[0006] A faucet water purifier includes a housing, and an internal water circuit is arranged in the housing. The internal water circuit includes a water inlet channel, a first water outlet channel, and a second water outlet channel;

[0007] A switching mechanism is arranged in the housing. The switching mechanism includes a connecting member and a blocking member. The connecting member is installed in the housing, and a cavity, a first drainage channel, and a second drainage channel are formed on the connecting member; the water inlet channel is communicated with the cavity, one end of the first drainage channel is communicated with the cavity, and the other end of the first drainage channel is communicated with the first water outlet channel; one end of the second drainage channel is communicated with the cavity, and the other end of the second drainage channel is communicated with the second water outlet channel. A filtering mechanism for filtering raw water is arranged in the second water outlet channel;

[0008] The blocking member is located in the cavity, and the blocking member is rotationally connected to the connecting member; when the blocking member rotates to the first position, the blocking member blocks the first drainage channel; when the blocking member rotates to the second position, the blocking member blocks the second drainage channel.

[0009] By adopting the above technical solution, when purified water is needed, the blocking member is rotated to the first position. At this time, the blocking member has a blocking effect on the first drainage channel. The water released through the faucet flows into the cavity through the water inlet channel. The water in the cavity flows into the second water outlet channel through the second drainage channel. The water in the second water outlet channel is filtered by the filter mechanism and then flows out. The filter mechanism has a filtering effect on chloramine and other substances in the water. The second water outlet channel finally discharges the purified water.

[0010] When raw water is needed, the blocking piece is rotated to the second position. At this time, the blocking piece has a blocking effect on the second drainage channel. The water released through the faucet flows into the cavity through the water inlet channel, and the water in the cavity flows to the first water outlet channel through the first drainage channel. The first water outlet channel finally discharges the raw water; therefore, the utilization efficiency of the filtering mechanism can be reduced, the service life of the filtering mechanism is extended, and thus the service life of the faucet water purifier is extended.

[0011] Optionally, a pushing member is fixedly provided on the blocking member, and a avoiding groove is provided on the shell. The pushing member passes through the avoiding groove, and the pushing member is slidably engaged with the avoiding groove.

[0012] By adopting the above technical solution, since the push member passes through the avoidance groove, the user can rotate the blocking member by moving the push member out of one end of the shell according to actual water use needs, thereby facilitating switching between raw water and purified water according to actual needs.

[0013] Optionally, a guide block is fixedly provided on the pushing member, two guide members are fixedly provided in the shell, and the guide block is slidably provided between the two guide members.

[0014] By adopting the above technical solution, the two guide members have a guiding effect on the guide block, which increases the sliding stability of the guide block, thereby increasing the sliding stability of the pusher, and thus increasing the swinging stability of the swinging member.

[0015] Optionally, the filtering mechanism includes a filter cartridge, which is installed in the second water outlet channel, with both ends of the filter cartridge being open; a first filter element, a second filter element and a third filter element are sequentially installed in the filter cartridge.

[0016] By adopting the above technical solution, since the filter cartridge is installed in the second water outlet channel and both ends of the filter cartridge are open, when the water in the second water outlet channel is sent to the filter cartridge, it flows from one end of the filter cartridge to the other end of the filter cartridge. In this process, the first filter element, the second filter element and the third filter element all have a filtering effect on the water, thereby facilitating the filtration of impurities such as chloramine in the water, thereby ensuring that the water that finally flows out through the second water outlet channel is clean water.

[0017] Optionally, the filter cartridge is in threaded engagement with the housing, and one end of the filter cartridge extends into the housing.

[0018] By adopting the above technical solution, since the filter cartridge is in threaded engagement with the housing, when too much debris accumulates in the filter cartridge, one end of the filter cartridge extending out of the housing can be rotated, so as to facilitate the removal of the filter cartridge from the housing, and thus facilitate the cleaning of the debris in the filter cartridge, ensuring the smoothness of the filtering mechanism.

[0019] Optionally, the housing includes an intermediate housing, and the switching mechanism is located inside the intermediate housing; a connecting housing is fixedly arranged on the intermediate housing, and the water inlet channel penetrates through the connecting housing; the connecting housing includes a first cylinder, a second cylinder and a connecting cylinder, the connecting cylinder is fixed on the intermediate housing, a clamping mechanism for clamping the first cylinder is arranged inside the connecting cylinder, and the second cylinder is located between the first cylinder and the switching mechanism; an external thread is provided at one end of the first cylinder extending out of the connecting cylinder.

[0020] By adopting the above technical solution, the clamping mechanism has a fixing effect on the first cylinder, so as to fix the first cylinder on the connecting cylinder. At the same time, since the second cylinder is located between the first cylinder and the switching mechanism, the first cylinder and the switching mechanism have a clamping effect on the second cylinder, so as to fix the second cylinder; since an external thread is provided at one end of the first cylinder extending out of the connecting cylinder, the convenience of installation and disassembly of the faucet water purifier by the staff is increased.

[0021] Optionally, the number of the clamping mechanisms is multiple, and each clamping mechanism includes a rotating member, an elastic member and a pressing member. The rotating member is rotatably arranged inside the connecting housing, the elastic member is fixed inside the connecting housing, the elastic member is located between the connecting housing and the rotating member, one end of the elastic member abuts against one end of the rotating member, and the other end of the elastic member abuts against the inner side wall of the connecting cylinder. The elastic member is used to drive the end of the rotating member to move towards the direction close to the first cylinder; the pressing member includes a pressing part and an anti-detachment part. The pressing part is located between the rotating member and the connecting cylinder, and the anti-detachment part abuts against the end of the rotating member away from the elastic member; a through hole is provided on the connecting cylinder, the pressing part passes through the through hole, and the pressing part is in sliding fit with the connecting cylinder.

[0022] By adopting the above technical solution, since one end of the elastic member abuts against one end of the rotating member and the other end of the elastic member abuts against the inner side wall of the connecting cylinder, the elastic force of the elastic member drives one end of the rotating member to move towards the direction close to the first cylinder; since the number of clamping mechanisms is multiple, the number of rotating members is also multiple. When one ends of the multiple rotating members move towards the direction close to the first cylinder simultaneously, the ends of the multiple rotating members have a clamping effect on the first cylinder, thereby realizing the fixation of the first cylinder within the connecting cylinder; when it is necessary to disassemble the first cylinder, by pressing one end of the pressing portion passing through the through hole, the pressing portion drives the anti-disengagement portion to move towards the direction close to the first cylinder, and the anti-disengagement portion pushes the end of the rotating member towards the direction close to the cylinder end. At this time, the other end of the rotating member moves towards the direction away from the first cylinder, thereby releasing the clamping effect of the multiple rotating members on the first cylinder, increasing the convenience for the staff to install and disassemble the first cylinder; at the same time, the end of the rotating member and the connecting cylinder squeeze the elastic member so that the elastic member stores elastic potential energy; at the same time, the connecting cylinder and the first cylinder have a limiting effect on the anti-disengagement portion, which can prevent the pressing member from separating from the connecting cylinder.

[0023] Optionally, a limiting post is fixedly arranged on the rotating member, and one end of the elastic member is sleeved on the limiting post.

[0024] By adopting the above technical solution, when the rotating member squeezes the elastic member, the limiting post has a limiting effect on the end of the elastic member, preventing the elastic member from shifting during the squeezing process.

[0025] Optionally, the second cylinder is sleeved on one end of the first cylinder. A plurality of first flanges are fixedly arranged on one end of the first cylinder, and a plurality of second flanges are fixedly arranged on one end of the second cylinder. The plurality of first flanges are engaged with the plurality of second flanges.

[0026] By adopting the above technical solution, since the plurality of first flanges on the first cylinder are engaged with the plurality of second flanges on the second cylinder, it is convenient to drive the second cylinder to rotate by rotating the end of the first cylinder extending out of the housing.

[0027] Optionally, a prompting mechanism is arranged on the housing. The prompting mechanism includes a display screen and a power supply module. The display screen is fixed on the housing, the power supply module is located inside the housing, and the display screen is electrically connected to the power supply module.

[0028] By adopting the above technical solution, the power supply module senses the water volume in the water purifier, and then the display screen displays the water volume in the faucet water purifier and the water volumes in the first water outlet channel and the second water outlet channel, so that consumers can more intuitively and efficiently understand the water volume inside the faucet water purifier.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. When it is necessary to use purified water, by rotating the plugging member to the first position, at this time the plugging member plugs the first drainage channel. The water released through the faucet flows through the water inlet channel and is sent to the cavity. The water in the cavity flows through the second drainage channel and is sent to the second water outlet channel. The water in the second water outlet channel flows out after being filtered by the filtering mechanism. The filtering mechanism filters substances such as chloramine in the water, and finally the second water outlet channel discharges the purified water. When it is necessary to use raw water, by rotating the plugging member to the second position, at this time the plugging member plugs the second drainage channel. The water released through the faucet flows through the water inlet channel and is sent to the cavity. The water in the cavity flows through the first drainage channel and is sent to the first water outlet channel, and the first water outlet channel finally discharges the raw water. Therefore, the usage efficiency of the filtering mechanism can be reduced, the service life of the filtering mechanism is extended, and thus the service life of the faucet water purifier is extended.

[0031] 2. Since the filter cartridge is installed in the second water outlet channel and both ends of the filter cartridge are open, when the water in the second water outlet channel flows to the filter cartridge, it flows from one end of the filter cartridge to the other end. During this process, the first filter element, the second filter element, and the third filter element all filter the water, which is convenient for filtering impurities such as chloramine in the water, so as to ensure that the water flowing out through the second water outlet channel is finally purified water.

[0032] 3. The power module senses the water volume in the water purifier, and then the display screen displays the water volume in the faucet water purifier and the water volumes in the first water outlet channel and the second water outlet channel, so that consumers can more intuitively and efficiently understand the water volume inside the faucet water purifier.

[0041] The following is further described in detail with reference to the attached Figure 1-6 drawings to further illustrate this application.

[0042] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which this application belongs. The "first", "second" and similar terms used in this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0043] An embodiment of this application discloses a faucet water purifier. Refer to Figure 1 , the faucet water purifier includes a housing 1, and the housing 1 includes an intermediate housing 11, and both ends of the intermediate housing 11 are open. A first end housing 13 is threadedly engaged with one end of the intermediate housing 11, a second end housing 14 is threadedly engaged with the other end of the intermediate housing 11, and a connecting housing 12 is also fixedly arranged on one side of the intermediate housing 11, which increases the convenience for users to install and disassemble the housing 1.

[0044] Refer to Figure 1 and Figure 2, Further, the connecting shell 12 includes a first cylinder 121, a second cylinder 122 and a connecting cylinder 123. The connecting cylinder 123 is fixed to the middle shell 11. A clamping mechanism 5 for clamping the first cylinder 121 is arranged in the connecting cylinder 123. The second cylinder 122 is located between the first cylinder 121 and the middle shell 11. An external thread is provided at one end of the first cylinder 121 extending out of the connecting cylinder 123. The clamping mechanism 5 has a fixing effect on the first cylinder 121, so as to fix the first cylinder 121 to the connecting cylinder 123. At the same time, since the second cylinder 122 is located between the first cylinder 121 and the switching mechanism 3, the first cylinder 121 and the switching mechanism 3 have a clamping effect on the second cylinder 122, so as to fix the second cylinder 122. Since an external thread is provided at one end of the first cylinder 121 extending out of the connecting cylinder 123, the convenience of installation and disassembly of the faucet water purifier by the staff is increased.

[0045] Refer to Figure 2 , the second cylinder 122 is sleeved on one end of the first cylinder 121. A plurality of first flanges are fixedly arranged at one end of the first cylinder 121 close to the second cylinder 122. A plurality of second flanges are fixedly arranged at one end of the second cylinder 122. The plurality of first flanges and the plurality of second flanges are meshed with each other. Since the plurality of first flanges on the first cylinder 121 and the plurality of second flanges on the second cylinder 122 are meshed with each other, it is convenient to drive the second cylinder 122 to rotate by rotating one end of the first cylinder 121 extending out of the housing 1.

[0046] Continue to refer to Figure 2 , the number of the clamping mechanisms 5 is multiple. In this embodiment, the number of the clamping mechanisms 5 is two. The two clamping mechanisms 5 are both located in the connecting cylinder 123, and the two clamping mechanisms 5 are respectively located on both sides of the connecting cylinder 123. Specifically, each clamping mechanism 5 includes a rotating member 51, an elastic member 52 and a pressing member 53. Rotating shafts 125 are integrally formed on opposite sides in the connecting cylinder 123. The rotating shafts 125 pass through the middle of the rotating member 51, and the rotating member 51 is rotatably connected to the rotating shafts 125. The elastic member 52 is fixed in the connecting shell 12. The elastic member 52 is located between the connecting shell 12 and the rotating member 51. One end of the elastic member 52 abuts against one end of the rotating member 51, and the other end of the elastic member 52 abuts against the inner side wall of the connecting cylinder 123. The elastic member 52 is used to drive the end of the rotating member 51 to move towards the direction close to the first cylinder 121. In this embodiment, specifically, the elastic member 52 can be a spring. The pressing member 53 includes a pressing part 531 and an anti-detachment part 532 integrally formed. The diameter of the anti-detachment part 532 is larger than that of the pressing part 531. The pressing part 531 is located between the rotating member 51 and the connecting cylinder 123. The anti-detachment part 532 abuts against the end of the rotating member 51 far from the elastic member 52. A through hole 124 is provided on the connecting cylinder 123. The pressing part 531 passes through the through hole 124, and the pressing part 531 is slidably matched with the connecting cylinder 123.

[0047] Continue to refer to Figure 2 Since one end of the elastic member 52 abuts against one end of the rotating member 51 and the other end of the elastic member 52 abuts against the inner side wall of the connecting cylinder 123, the elastic force of the elastic member 52 drives one end of the rotating member 51 to move towards the direction close to the first cylinder 121. Since the number of the clamping mechanisms 5 is multiple, the number of the rotating members 51 is also multiple. When one ends of the multiple rotating members 51 move towards the direction close to the first cylinder 121 simultaneously, the ends of the multiple rotating members 51 have a clamping effect on the first cylinder 121, so as to fix the first cylinder 121 in the connecting cylinder 123; when the first cylinder 121 needs to be disassembled, by pressing one end of the pressing part 531 passing through the through hole 124, the pressing part 531 drives the anti - detachment part 532 to move towards the direction close to the first cylinder 121, and the anti - detachment part 532 pushes the end of the rotating member 51 to move towards the end close to the cylinder. At this time, the other end of the rotating member 51 moves away from the first cylinder 121, so as to release the clamping effect of the multiple rotating members 51 on the first cylinder 121, which increases the convenience for the staff to install and disassemble the first cylinder 121, and thus facilitates the replacement of the first cylinder 121. At the same time, the end of the rotating member 51 and the connecting cylinder 123 squeeze the elastic member 52 so that the elastic member 52 stores elastic potential energy; at the same time, the connecting cylinder 123 and the first cylinder 121 have a limiting effect on the anti - detachment part 532, which can prevent the pressing member 53 from detaching from the connecting cylinder 123.

[0048] Continue to refer to Figure 2 A limiting post 511 is fixedly arranged on the rotating member 51, and one end of the elastic member 52 is sleeved on the limiting post 511. When the rotating member 51 squeezes the elastic member 52, the limiting post 511 has a limiting effect on the end of the elastic member 52 to prevent the elastic member 52 from shifting during the squeezing process.

[0049] Refer to Figure 1 and Figure 3 As shown in FIGS. and, an internal water channel 2 is arranged in the housing 1, and the internal water channel 2 includes a water inlet channel 21, a first water outlet channel 22 and a second water outlet channel 23. The water inlet channel 21 is located in the connecting housing 12, the first water outlet channel 22 is located in the middle housing 11, and the second water outlet channel 23 sequentially penetrates through the first end housing 13, the middle housing 11 and the second end housing 14.

[0050] Refer to Figure 3 and Figure 4, in this embodiment, a switching mechanism 3 is provided inside the intermediate housing 11. Specifically, the switching mechanism 3 includes a connecting member 31 and a blocking member 32. Among them, the connecting member 31 is installed inside the intermediate housing 11. A cavity 311, a first drainage channel 312, and a second drainage channel 313 are formed on the connecting member 31. One end of the water inlet channel 21 is communicated with the outside of the housing 1, and the other end of the water inlet channel 21 is communicated with the cavity 311. One end of the first drainage channel 312 is communicated with the cavity 311, and the other end of the first drainage channel 312 is communicated with the first water outlet channel 22. One end of the second drainage channel 313 is communicated with the cavity 311, and the other end of the second drainage channel 313 is communicated with the second water outlet channel 23. A filtering mechanism 4 for filtering raw water is provided inside the second water outlet channel 23. The blocking member 32 is located inside the cavity 311. The blocking member 32 passes through the connecting member 31, and the blocking member 32 is rotatably connected to the connecting member 31. When the blocking member 32 rotates to the first position, the blocking member 32 blocks one end of the first drainage channel 312 close to the cavity 311. When the blocking member 32 rotates to the second position, the blocking member 32 blocks one end of the second drainage channel 313 close to the cavity 311.

[0051] Refer to Figure 3 and Figure 4 , when it is necessary to use purified water, by rotating the blocking member 32 to the first position, at this time, the blocking member 32 has a blocking effect on the first drainage channel 312. The water released through the faucet flows through the water inlet channel 21 and is sent to the cavity 311. The water in the cavity 311 flows through the second drainage channel 313 and is sent to the second water outlet channel 23. The water in the second water outlet channel 23 flows out after being filtered by the filtering mechanism 4. The filtering mechanism 4 has a filtering effect on chlorine ammonia and the like in the water. The second water outlet channel 23 finally discharges the purified water.

[0052] Continue to refer to Figure 3 and Figure 4 , when it is necessary to use raw water, by rotating the blocking member 32 to the second position, at this time, the blocking member 32 has a blocking effect on the second drainage channel 313. The water released through the faucet flows through the water inlet channel 21 and is sent to the cavity 311. The water in the cavity 311 flows through the first drainage channel 312 and is sent to the first water outlet channel 22, and the first water outlet channel 22 finally discharges the raw water; Therefore, the usage efficiency of the filtering mechanism 4 can be reduced, the service life of the filtering mechanism 4 can be extended, and thus the service life of the faucet water purifier can be extended.

[0053] Refer to Figure 1 and Figure 4A pusher 33 is fixedly mounted on the blocking member 32. A relief groove 111 is formed on the intermediate shell 11. The pusher 33 passes through the relief groove 111 and slides in engagement with the relief groove 111. Since the pusher 33 passes through the relief groove 111, the user can rotate the blocking member 32 according to actual water needs by moving the end of the pusher 33 that passes through the shell 1, thereby facilitating switching between raw water and purified water as needed. At the same time, the relief groove 111 guides and limits the pusher 33, which not only increases the stability of the movement of the pusher 33 but also limits its travel.

[0054] Reference Figure 4 and Figure 5 A guide block 331 is fixedly mounted on the pusher 33. Two guide members 112 are integrally formed within the guide member of the connecting shell 12. The two guide members 112 are parallel to each other. The adjacent side walls of the two guide members 112 are each provided with a guide groove 113. The two sides of the guide block 331 are respectively positioned within the two guide grooves 113, and the guide blocks 331 slideably engage with the two guide grooves 113. The two guide grooves 113 guide the guide blocks 331, increasing the sliding stability of the guide blocks 331, thereby increasing the sliding stability of the pusher 33, and thus increasing the swinging stability of the swinging member.

[0055] Reference Figure 1 and Figure 6 In this embodiment, the filter mechanism 4 is installed within the second end housing 14. The filter mechanism 4 is connected to one end of the second water outlet channel 23. Specifically, the filter mechanism 4 includes a filter cartridge 41. A mounting hole 141 is defined on one side of the second end housing 14. The filter cartridge 41 passes through the mounting hole 141 and is threadedly engaged with the second end housing 14. One end of the filter cartridge 41 extends from the second end housing 14, and both ends of the filter cartridge 41 are open. Because the filter cartridge 41 is threadedly engaged with the housing 1, when excessive debris accumulates within the filter cartridge 41, the filter cartridge 41 can be rotated to extend out of one end of the housing 1, thereby facilitating removal from the housing 1. This facilitates cleaning of debris within the filter cartridge 41 and ensures the smooth operation of the filter mechanism 4.

[0056] Reference Figure 6, a first filter element 42, a second filter element 43, and a third filter element 44 are sequentially installed inside the filter cartridge 41. Specifically, the second filter element 43 is installed on the inner side wall of the housing 1, the first filter element 42 is installed on the second filter element 43, the first filter element 42 is located at one end where the filter cartridge 41 extends into the second end housing 14, and the third filter element 44 is installed at the end where the filter cartridge 41 extends out of the second end housing 14. It should be noted that a plurality of through filter holes are provided on the first filter element 42, the second filter element 43, and the third filter element 44. Since the filter cartridge 41 is installed in the second water outlet channel 23 and both ends of the filter cartridge 41 are open, when the water flow in the second water outlet channel 23 is sent to the filter cartridge 41, it flows from one end of the filter cartridge 41 to the other end. During this process, the filter holes on the first filter element 42, the second filter element 43, and the third filter element 44 all filter the water, thereby facilitating the filtration of impurities such as chloramine in the water, and ensuring that the water finally flowing out through the second water outlet channel 23 is clean water.

[0057] Refer to Figure 4 and Figure 6 , wherein a filter element 15 is installed inside the first end housing 13, and the shape of the filter element 15 is cylindrical. The water in the second water outlet channel 23 sequentially passes through the filter element 15 and the filtering mechanism 4, and both the filter element 15 and the filtering mechanism 4 filter the raw water. The filtering principle of the filter element 15 for water is prior art and will not be elaborated here.

[0058] Refer to Figure 1 , a prompting mechanism 6 is provided on the housing 1. The prompting mechanism 6 includes a display screen and a power module. The display screen is fixed on the housing 1, the power module is located inside the housing 1, and the display screen is electrically connected to the power module. The power module senses the water volume inside the water purifier, and then the display screen displays the water volume inside the faucet water purifier and the water volumes in the first water outlet channel 22 and the second water outlet channel 23, so that consumers can more intuitively and efficiently understand the water volume inside the faucet water purifier.

[0059] The implementation principle of the above embodiment is as follows: When clean water is needed, by rotating the plugging member 32 to the first position, at this time the plugging member 32 plugs the first drainage channel 312. The water released through the faucet flows through the water inlet channel 21 and is sent to the cavity 311. The water in the cavity 311 flows through the second drainage channel 313 and is sent to the second water outlet channel 23. The water in the second water outlet channel 23 flows out after being filtered by the filtering mechanism 4. The filtering mechanism 4 filters substances such as chloramine in the water, and finally the second water outlet channel 23 discharges the clean water;

[0060] When the raw water needs to be used, by rotating the plugging member 32 to the second position, at this time the plugging member 32 plugs the second drainage channel 313, and the water released through the faucet flows into the cavity 311 through the water inlet channel 21. The water in the cavity 311 flows into the first water outlet channel 22 through the first drainage channel 312, and the first water outlet channel 22 finally discharges the raw water; thus, the usage efficiency of the filtering mechanism 4 can be reduced, the service life of the filtering mechanism 4 can be extended, and thus the service life of the faucet water purifier can be extended.

[0061] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
