The embodiment of the first aspect of the present application proposes a water treatment structure, as shown in fig. 1 to 4, including a housing 100 and a first sealing member 200. The housing 100 defines a water passage 110 and a first receiving chamber 120, the first receiving chamber 120 is used for receiving a water treatment agent 700, and the water treatment agent 700 includes but is not limited to: the scale inhibitor for inhibiting scale condensation, the bacteriostatic agent for inhibiting bacterial reproduction, the deodorant for refreshing and deodorizing and the like, and all the water treatment agents 700 can be filled into the first accommodating cavity 120, so that the water treatment structure can be suitable for the use condition of each water treatment agent 700, and for avoiding repeated description, the scale inhibitor is taken as an example in the application, but the water treatment structure is not understood to be only suitable for the use condition of the scale inhibitor.

The scale inhibitor can be dissolved in water and release scale inhibition active factors, and scale crystal nuclei are interfered at the initial stage of scale formation, so that the scale crystal nuclei cannot be continuously condensed to form scale. When water flows in the water passage 110, a certain amount of water exists in the first accommodating cavity 120 under the action of water pressure and contacts with the scale inhibitor, so that the scale inhibitor releases scale inhibition active factors to form a scale prevention water body. The water passing channel 110 comprises a first pipe section 111 and a second pipe section 112 which are communicated with each other, the first pipe section 111 and the second pipe section 112 are sequentially arranged along the moving direction of water flow, the state of the water flow in the water passing channel 110 is controlled by a switch of the terminal water equipment, and when the terminal water equipment is started, the water flow flows along the direction from the first pipe section 111 to the second pipe section 112; when the terminal water using equipment is closed, the water flow stops flowing, and a closed water body is formed in a pipeline between the water treating structure and the water using equipment.

As shown in fig. 3 and 4, the housing 100 is provided with a first through hole 121 and a second through hole 122, one end of the first through hole 121 is communicated with the first accommodating cavity 120, the other end is communicated with the first tube section 111, one end of the second through hole 122 is communicated with the first accommodating cavity 120, and the other end is communicated with the second tube section 112. The second through hole 122 is a main release passage of the scale inhibitor, the first through hole 121 mainly plays a role in balancing water pressure in the first pipe section 111 and the first accommodating cavity 120, the aperture of the first through hole 121 is small, the scale inhibitor cannot pass through or only can pass through a small amount, and the first through hole 121 and the second through hole 122 form a water loop in the first accommodating cavity 120 and the water passing channel 110, so that the scale-proof water body in the first accommodating cavity 120 can be mixed with the water body in the water passing channel 110, and further the water body in the water passing channel 110 is prevented from generating scale.

The first sealing member 200 is at least partially located in the second through hole 122, and the specific operation process of the water treatment structure is as follows: when the external water valve is opened and water flows move, the water pressure in the first pipe section 111 is greater than the water pressure in the second pipe section 112, the first through hole 121 is communicated with the first pipe section 111 and the first accommodating cavity 120, a relatively high pressure is formed in the first accommodating cavity 120, a relatively low pressure is formed in the second pipe section 112, a pressure difference is formed at two ends of the first sealing element 200, the first sealing element 200 is driven to move downwards, so that the first sealing element 200 seals the second through hole 122, the second through hole 122 of a main release channel of the scale inhibitor is closed, the scale inhibition active factors cannot be released into the rapidly moving water flow or only a small part of the scale inhibition active factors are released into the rapidly moving water flow through the first channel 121, and the release amount is greatly reduced. Or, when the external water valve is closed and the water flow is relatively static, the water pressure in the first pipe section 111 is equal to the water pressure in the second pipe section 112, there is no pressure difference between the upper end and the lower end of the first sealing member 200, the first sealing member 200 moves upwards under the action of buoyancy or other forces, so that the first sealing member 200 opens the second through hole 122, the first accommodating cavity 120 is communicated with the water passage 110, and the anti-scaling water in the first accommodating cavity 120 is mixed with the closed water in the water passage 110 to prevent scale from being generated in the water passage 110. When the water pressure in the first pipe segment 111 is lower than the water pressure in the second pipe segment 112, it can be understood that the first sealing member 200 is moved upward and the second through hole 122 is opened.

In the fast moving water flow, the scale can not be condensed on the inner wall of the pipeline to form the scale, and in the prior art, the scale inhibitor is placed in the water passing channel 110, is dissolved in a large amount when the water flows and flows out of the water using equipment along with the water flow, can not effectively play a role in preventing the scale of the water using equipment or the pipeline, and further causes water pollution in a large range. Compare in forming the incrustation scale in flowing water, condense out the incrustation scale on the inner wall of water pipe more easily in the confined water, the water treatment structure of this application realizes closing and the intercommunication of second through-hole 122 automatically to two kinds of rivers states when rivers remove and rivers are static, and then opens at terminal water equipment, and during rivers remove, second through-hole 122 closes, and the release amount of antisludging agent reduces by a wide margin, and the antisludging agent obtains preserving. The terminal water equipment is closed, when the water flow is static, the second through hole 122 is opened, and the scale inhibitor is normally released into the closed water body to prevent scale from condensing.

Based on the foregoing, the water treatment structure of the application can realize effective release of the scale inhibitor based on the water flow state, greatly save the usage amount of the scale inhibitor, prolong the service time of the scale inhibitor after single filling, and save the scale inhibition cost. Meanwhile, the scale inhibition on the closed water body in a targeted manner can improve the success rate of scale inhibition, reduce the waste of scale inhibitor caused by ineffective scale inhibition on the flowing water body and reduce the pollution to water resources. It is understood that the scale inhibitor may be replaced with a bacteriostatic, odor removing or other water treatment agent 700 to prevent bacterial growth or odor generation in the enclosed body of water.

Based on the above, the specific embodiment in which the first sealing member 200 automatically switches the closed state or the open state of the second through hole 122 according to the water flow state may be any one of the following:

1. as shown in fig. 4, the first seal 200 is made of plastic, rubber, or other material having a density slightly less than water to enable the first seal 200 to float in the enclosed body of water. When the outer water valve is closed to form a closed body of water in the water passage 110, the first sealing member 200 is moved upward by the buoyancy force due to the water pressure in the first pipe segment 111 being equal to the water pressure in the second pipe segment 112, thereby opening the second through-hole 122. When the external water valve opens the flow of water to form a pressure difference between the upper and lower ends of the first sealing member 200, the first sealing member 200 is subjected to a pressure greater than buoyancy, the first sealing member 200 moves downward, and the second through hole 122 is closed.

2. As shown in fig. 5, the first sealing member 200 defines a closed buoyancy chamber 230, and compared to the above embodiment, the opening of the second through hole 122 is achieved by buoyancy by forming the buoyancy chamber 230 inside the first sealing member 200 so that the average density of the first sealing member 200 is less than that of water.

3. As shown in fig. 6, the water treatment structure further includes a first elastic member 250, one end of the first elastic member 250 abuts against the lower end of the sealing portion 210 of the first sealing member 200, and the other end is connected to the housing 100, for example, the first elastic member can be connected to a cavity wall of the first accommodating cavity 120 having the first through hole 121 or a cavity wall of the second through hole 122. When the water pressure in the first pipe section 111 is higher than the water pressure in the second pipe section 112, the first elastic member 250 is compressed, the downward pressure on the first sealing member 200 is higher than the upward thrust on the first sealing member 200, and when the difference between the water pressures in the first pipe section 111 and the second pipe section 112 is higher than a set value, the first sealing member 200 moves downward to close the second through hole 122. Alternatively, when the sum of the water pressure of the second pipe segment 112 and the elastic force of the first elastic member 250 in the compressed state is greater than the water pressure in the first accommodating chamber 120, the first elastic member 250 has a tendency to recover elastic deformation to drive the first sealing member 200 to move upward to open the second through hole 122.

Any of the above embodiments can automatically drive the first sealing element 200 to open or close the second through hole 122 through the water flow state, so that the scale inhibiting active factors in the first accommodating cavity 120 can be released or retained, and the situation that the scale inhibitor is quickly lost along with the flow of water flow is reduced.

As shown in fig. 7, the first sealing element 200 includes a sealing portion 210 and a guiding portion 220, the guiding portion 220 is disposed through the second through hole 122, and the guiding portion 220 is disposed in the second through hole 122 no matter the first sealing element 200 moves downward or upward, so that the first sealing element 200 can move axially, and the first sealing element 200 is prevented from being unable to be reset when being subsequently pressed downward after moving upward to separate from the second through hole 122. As shown in fig. 7, four guide grooves 221 are uniformly distributed in the circumferential direction of the guide part 220, when the first sealing element 200 moves upward, two ends of each guide groove 221 communicate with the first accommodating cavity 120 and the water passage 110, so that water containing scale inhibition active factors in the first accommodating cavity 120 is mixed with the water passage 110, the guide grooves 221 enable the guide part 220 to penetrate through the second through hole 122 to play a role in positioning, and the water passing capacity of the second through hole 122 is not affected, thereby preventing the scale inhibition active factors in the first accommodating cavity 120 from being released into the water passage 110 due to the blockage of the guide part 220.

As shown in fig. 3 and 4, the second through hole 122 is closed by a pressure difference, specifically, the inner diameter of the first pipe section 111 is gradually reduced along the direction from the first pipe section 111 to the second pipe section 112, so that the water flow speed is gradually increased and the water pressure is gradually reduced when the water flows from the first pipe section 111 to the second pipe section 112, so that a relatively high pressure is formed in the first pipe section 111 and a relatively low pressure is formed in the second pipe section 112. Further, as shown in fig. 4, the inner diameter of the second pipe section 112 is larger than the inner diameter of the small end of the first pipe section 111. After the water flow is accelerated through the first pipe section 111, the water flow enters the second pipe section 112 with larger cross section, the water flow is expanded in the second pipe section 112, the water pressure is further reduced, and the pressure difference between the first pipe section 111 and the second pipe section 112 is larger, so that the pressure greater than the buoyancy of the first sealing member 200 is provided.

Based on the above embodiments, as shown in fig. 4, a first non-return valve 400 is disposed in the first through hole 121 to make the water flow move in one direction along the direction from the first pipe section 111 to the first receiving cavity 120. Specifically, since the first through hole 121 plays a role in balancing the pressures in the first receiving chamber 120 and the first pipe section 111, when a relatively high pressure is formed in the first pipe section 111, if the water pressure in the first receiving chamber 120 is lower than the water pressure in the first pipe section 111, the first check valve 400 is briefly opened to form a relatively high pressure in the first receiving chamber 120 equal to the relatively high pressure in the first pipe section 111, and then the first check valve 400 is closed to prevent the scale inhibition active factor from being released into the water passage 110 through the first through hole 121.

In some embodiments, as shown in fig. 2 and 3, the water treatment structure further includes a filter 500 and a top cover 550, the filter 500 is a filter screen structure for containing the scale inhibitor, and the water in the first accommodating chamber 120 contacts the scale inhibitor through the filter 500, so that the scale inhibiting active factor is released into the water body. The filter 500 can concentrate the scale inhibitor, prevent the scale inhibitor from blocking the first through hole 121 or the second through hole 122, and slow down the dissolution rate of the scale inhibitor, so that the scale inhibitor is fully dissolved from the outer layer to the inner layer. Filter 500 and set up in first holding chamber 120, casing 100 has seted up the installing port, and filter 500 can take out or pack into from the installing port, and the installing port is located to top cap 550 lid, and is connected with casing 100 is detachable, and then takes off top cap 550 after, can be directly to filtering 500 interior supplementary antisludging agent, or directly take out and filter 500 and carry out the replenishment of antisludging agent. Furthermore, a fourth pipe segment 114 is disposed on the housing 100, one end of the fourth pipe segment 114 is detachably connected to the housing 100, the other end is detachably connected to the top cover 550, and the first pipe segment 111 defines part of the first accommodating cavity 120. Since the first receiving cavity 120 has a certain depth, the difficulty of the manufacturing process of the housing 100 as shown in the figure is high, and therefore, the first receiving cavity 120 is formed by a sectional structure, so as to reduce the processing depth of the main body of the housing 100 and reduce the processing difficulty of the complex structure on the housing 100.

Further, as shown in fig. 4, the housing 100 further defines a second receiving cavity 130, and is provided with a third through hole 131, the second receiving cavity 130 is connected to the second pipe segment 112 through the second through hole 122, and is connected to the first receiving cavity 120 through the third through hole 131, the water treatment structure further includes a second sealing element 300 and a second elastic element 350, the second sealing element 300 and the second elastic element 350 are disposed in the second receiving cavity 130, and one end of the second sealing element 300 abuts against the second elastic element 350, and the other end extends to abut against the bottom surface of the filter element 500, when the filter element 500 is taken out, the second elastic element 350 drives the second sealing element 300 to move to close the third through hole 131.

Specifically, as shown in fig. 4, the second sealing member 300 includes a core rod 310 and a sealing ring 320, the core rod 310 abuts against the second elastic member 350 and can move axially, the sealing ring 320 is sleeved on the core rod 310, when the core rod 310 is pressed downward by the filtering member 500, the third through hole 131 is opened, and when the filtering member 500 is taken out and the core rod 310 is driven by the second elastic member 350 to move upward, the sealing ring 320 blocks the third through hole 131, so that the water passage 110 is separated from the first accommodating cavity 120.

Note that, in the moving direction in which the first seal 200 opens the second through hole 122, the first seal 200 and the second seal 300 are sequentially provided at intervals so that the first seal 200 can move upward to abut against the second seal 300, and the displacement of the first seal 200 in the axial direction can be restricted by the second seal 300. In a state where the filter member 500 is received in the first receiving chamber 120, the second sealing member 300 is pressed downward with a certain interval from the lower chamber wall of the second receiving chamber 130 so that the first sealing member 200 can be moved upward to abut against the lower end of the second sealing member 300 to define the maximum upward movement of the first sealing member 200.

In addition, as shown in fig. 2 and 3, the inlet end of the first pipe section 111 is provided with a second check valve 450 along the moving direction of the water flow, so that the water flow moves in one direction along the direction from the first pipe section 111 to the second pipe section 112, thereby preventing the water in the water passage 110 from flowing backwards to pollute the water source.
