[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.
[0027] like Figure 1-Figure 3 As shown, the utility model provides a water treatment device, including a shell 1, an inner sleeve 2 and an inner core 3, the inner sleeve 2 is arranged in the shell 1, a water treatment agent chamber 4 is formed between the shell 1 and the inner sleeve 2, and the water treatment agent chamber 4 is used to accommodate a water treatment agent 41; the inner core 3 is arranged in the inner sleeve 2, and the inner sleeve 2 is provided with a connecting hole 23 connected from the inner wall of the inner sleeve 2 to the water treatment agent chamber 4; a reset spring 5 is provided between the inner core 3 and the inner sleeve 2, one end of the reset spring 5 is connected to the inner core 3, and the other end is connected to the inner sleeve 2.
[0028] The inner core 3 has a sealing structure 31. When the inner sleeve 2 is in a hydrostatic state, the sealing structure 31 leaves the connecting hole 23 and is located on the water inlet side of the inner sleeve 2 under the drive of the return spring 5; when water flows through the inner sleeve 2, the inner core 3 can be pushed by the water pressure and move along the direction of the water flow, so that the sealing structure 31 closes the connecting hole 23.
[0029] The embodiment of the utility model sets the water treatment agent 41 on the outside of the inner sleeve 2 through which the water supply passes, which can prevent the water treatment agent 41 from contacting with a large amount of water flowing through, prolong the use time of the water treatment agent 41, and prolong the service life of the water treatment device. The water treatment agent 41 can use a scale inhibitor or a disinfectant according to actual needs to achieve the corresponding scale inhibition function and disinfection function, ensuring that the corresponding water outlet appliances such as showers will not breed scale or accumulate bacteria. Since the water treatment agent chamber 4 is arranged on the outside of the inner sleeve 2 through which the water supply passes, the volume of the chamber can be increased, thereby storing more water treatment agents 41. In combination with the above-mentioned slow-release structure, the service life can be further extended and the use cost can be reduced.
[0030] Preferably, the inner sleeve 2 is provided with an upper positioning ring 21 and a lower positioning ring 22, and the inner sleeve 2 is located between the upper positioning ring 21 and the lower positioning ring 22. In this embodiment, the lower positioning ring 22 is integrally formed in the inner sleeve 2.
[0031] According to the first embodiment of the utility model, the sealing structure 31 includes an upper sealing ring 31 and a lower sealing ring 32 arranged on the outer side of the inner core 3, the upper sealing ring 31 abuts against the inner sleeve 2, and the lower sealing ring 32 is used to cooperate with the lower positioning ring 22 to close the communication hole 23. In this embodiment, the sealing of the inner core 3 and the inner sleeve 2 is achieved by the upper sealing ring 31 and the lower sealing ring 32 spaced a predetermined distance from each other, and the upper sealing ring 31 and the lower sealing ring 32 can be commonly used O-rings for sealing, which can reduce the friction resistance between the inner core 3 and the inner sleeve 2, so that the relative sliding between the inner core 3 and the inner sleeve 2 is smoother and more sensitive.
[0032] According to the second embodiment of the utility model, Figure 4 As shown, the difference from the first embodiment is that the sealing structure 31 is changed into an integrated sealing ring 33 arranged on the outside of the inner core 3, and the integrated sealing ring 33 can close the communication hole 23. In order to achieve the above-mentioned goal, the integrated sealing ring 33 has a large thickness, so that when it is located on the surface of the communication hole 23, it can completely cover the communication hole 23 and close the communication hole 23. With this embodiment, the structure of the outer side of the inner core 3 can be simplified, and the difficulty of assembly can be reduced.
[0033] Preferably, a filter screen 6 is provided at the communication hole 23. It should be noted that the filter screen 6 can prevent the water treatment agent 41 from entering the inner sleeve 2 from the communication hole 23, but allows water mixed with the water treatment agent 41 to enter the water outlet from the communication hole 23.
[0034] In order to prevent the water containing the water treatment agent 41 from flowing back and causing water source pollution, the inner core 3 is provided with a check valve 7. The check valve 7 allows water to flow from the water inlet side of the inner core 3 to the water outlet side, but prohibits water from flowing from the water outlet side of the inner core 3 to the water inlet side, thereby preventing the water treatment agent 41 on the water inlet side from contacting the water source.
[0035] Preferably, the upper positioning ring 21 is a snap ring, and a snap groove 24 is provided on the inner side of the inner sleeve 2, and the snap ring is clamped in the snap groove 24. The upper positioning ring 21 is designed as a snap ring, so that it cooperates with the snap groove 24 on the inner side of the inner sleeve 2 to support the inner core 3 and form the upper limit of the stroke of the inner core 3, with low production cost and convenient assembly and processing.
[0036] The shell 1 has an inlet end 11 and an outlet end 12, and the inner sleeve 2 is connected to the inlet end 11 and the outlet end 12. An O-ring 25 is provided at the connection between the inner sleeve 2 and the inlet end 11 and the outlet end 12. The O-ring 25 forms a seal at the connection between the inner sleeve 2 and the shell 1, thereby cooperating with the shell structure that bulges outward to form the water treatment agent chamber 4. The water treatment agent chamber 4 can only contact the water in the inner sleeve 2 through the connecting hole 23, so as to avoid the water treatment agent 41 from contacting with a large amount of water during use and quickly losing its service life. Specifically, the shell 1 includes an upper cover 13 and a lower cover 14, and the upper cover 13 and the lower cover 14 are screwed together by threads. The water inlet end 11 is located in the upper cover 13, and the water outlet end 12 is located in the lower cover 14.
[0037] The utility model provides a water treatment device whose working principle is as follows:
[0038] 1. As Figure 3 As shown, the water treatment agent 41 takes a scale inhibitor as an example. When the main valve is not opened, the inner core 3 moves upward under the elastic force of the reset spring 5 until the inner core 3 contacts the end face of the upper positioning ring 21. At this time, the upper sealing ring 31 or the integrated sealing ring 33 on the inner core 3 and the inner wall of the inner sleeve 2 form a seal, and the lower end channel of the inner core 3 is opened, and the scale inhibitor factor in the scale inhibitor is released to the rear end waterway through this channel.
[0039] 2. If Figure 5As shown, when the main valve is opened, the inner core 3 overcomes the elastic force of the reset spring 5 under the action of water pressure and moves downward. In the first embodiment, the upper sealing ring 31 on the inner core 3 contacts the inner wall of the inner sleeve 2 above the connecting hole 23, and the lower sealing ring 32 contacts the lower positioning ring 22 below the connecting hole 23, and cooperates with the side wall of the inner core 3 to close the connecting hole 23, so that the inner cavity of the scale inhibitor is separated from the water flow. At this time, the scale inhibitor factor release channel of the scale inhibitor is closed, and the scale inhibitor in the scale inhibitor cannot continue to be released through the channel, thereby avoiding the contact between the flowing water and the scale inhibitor and extending the use time of the scale inhibitor; in the second embodiment, the connecting hole 23 is blocked by directly covering the surface of the connecting hole 23 with an integrated sealing ring 33.
[0040] 3. When the main valve is closed again, the water pressure force on the upper end surface of the inner core 3 disappears, and under the action of the elastic force of the reset spring 5, the inner core 3 moves upward again until the inner core 3 contacts the end surface of the upper positioning ring 21. At this time, the connecting hole 23 is connected with the water outlet end 12 at the lower end of the inner core 3 again, and the scale inhibitor factor in the scale inhibitor continues to be released to the rear end water channel through the water outlet end 12 to prevent scaling of the rear end shower head.
[0041] like Figure 6 As shown, the third embodiment of the present utility model further provides a water outlet device, which is provided with the water treatment device 100 as described above.
[0042] The above is a preferred embodiment of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present utility model.
