Technical Field

[0001] This utility model belongs to the field of pipeline filtration technology, specifically relating to a pipeline filtration protection device and a water tank structure. Background Technology

[0002] During the use of heat pump products, due to the different water quality in different regions and among different users, water containing more impurities can easily cause rust or scale buildup in the pipes and tank after flowing through them. Furthermore, since the pipes and tanks are mostly fixedly connected in related technologies, it is difficult to disassemble and clean them, which can lead to pipe blockage and affect the user's product experience. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a pipeline filtration protection device that can be used to filter impurities and extend the service life of the installed object.

[0004] The second objective of this utility model is to provide a water tank structure that employs the aforementioned pipeline filtration and protection device. This pipeline filtration and protection device can filter impurities, thereby extending the service life of the water tank structure and enhancing the user's product experience.

[0005] One of the objectives of this utility model is achieved through the following technical solution: A pipeline filtration protection device, characterized in that it comprises: The filter body is a tubular structure and has a first cavity inside. The first end of the filter body is provided with a first opening, the second end of the filter body is provided with a second opening, and a flip cover is movably provided at the second opening of the filter body; The filter body has at least one first filter mesh on its tube wall and at least one second filter mesh on its flip cover. The first opening, the second opening, the second filter mesh, and the first filter mesh are all connected to the first cavity to form a flow channel.

[0006] As an alternative implementation, the filter body is rotatably connected to a flip cover at the second opening.

[0007] As an optional implementation, the filter body is arranged along the lateral direction; The first opening and the second opening are set at the same height, or the second opening is set at a position higher than the first opening.

[0008] As an optional implementation, the filter body is provided with an installation step, and the filter body is detachably connected to the installation object through the installation step; The pipeline filter protection device also includes a sealing ring, which is fitted over the outside of the mounting step.

[0009] As an optional implementation, both the first and second filter mesh openings are diamond-shaped. Multiple first filter meshes are arranged at intervals along the length and circumference of the filter body, with adjacent rows or columns of first filter meshes staggered. Multiple second filter meshes are arranged at intervals along the radial direction of the flip cover and in a direction perpendicular to the radial direction, with adjacent rows or columns of second filter meshes being staggered.

[0010] As an optional implementation, a connector is provided at the first end of the filter body, and the connector is located near the first opening; The inner wall of the connector is provided with an internal thread for connecting the water inlet pipe, or the outer wall of the connector is provided with an external thread for connecting the water inlet pipe.

[0011] The second objective of this utility model is achieved by the following technical solution: A water tank structure including any one of the above-mentioned pipeline filtration and protection devices.

[0012] As an optional implementation, the water tank structure also includes a water tank body, the interior of which has a second cavity; The side wall of the water tank body is provided with mounting holes for installing the filter body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The pipeline filtration protection device of this utility model can be used to filter impurities. When there are few impurities in the first cavity of the filter body, water enters the filter body from the first opening and flows out through the first filter mesh or through the first filter mesh and the second filter mesh. Some impurities in the water are retained inside the first cavity, thereby preventing these impurities from entering the installed object and extending the service life of the installed object. At this time, the pipeline filtration protection device is in filtration mode. When there are too many impurities in the first cavity of the filter body, the cover can be opened by increasing the water pressure or increasing the water flow. Water enters the filter body from the first opening and flows out through the first filter mesh and the second opening, making it easier for the impurities in the first cavity of the filter body to be carried away by the water flow from the second opening. At this time, the pipeline filtration protection device is in sewage discharge mode.

[0016] 2. The water tank structure of this utility model adopts the above-mentioned pipeline filtration protection device. The pipeline filtration protection device can filter impurities, thereby extending the service life of the water tank structure and improving the user's product experience.

Unless otherwise stated, "a plurality of" means two or more.

[0028] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0029] Example 1 See Figures 1 to 3 This utility model discloses a pipeline filtration protection device, comprising: a filter body 10, which is a tube structure, and has a first cavity 101 inside; a first opening 102 is provided at the first end of the filter body 10, a second opening 103 is provided at the second end of the filter body 10, and a flip cover 20 is movably provided at the second opening 103; at least one first filter mesh 104 is provided on the tube wall of the filter body 10, and at least one second filter mesh 201 is provided on the flip cover 20; the first opening 102, the second opening 103, the second filter mesh 201, and the first filter mesh 104 are all connected to the first cavity 101 to form a flow channel.

[0030] The pipeline filtration protection device of this utility model can be used to filter impurities. When there are few impurities in the first cavity 101 of the filter body 10, water enters the filter body 10 from the first opening 102 and flows out through the first filter mesh 104, or water enters the filter body 10 from the first opening 102 and flows out through the first filter mesh 104 and the second filter mesh 201. Some impurities in the water are retained inside the first cavity 101, thereby preventing these impurities from entering the installed object and extending the service life of the installed object. At this time, the pipeline filtration protection device is in filtration mode. When there are too many impurities in the first cavity 101 of the filter body 10, the flip cover 20 can be opened by increasing the water pressure or increasing the water flow. Water enters the filter body 10 from the first opening 102 and flows out through the first filter mesh 104 and the second opening 103, making it easier for the impurities in the first cavity 101 of the filter body 10 to be carried away by the water flow from the second opening 103. At this time, the pipeline filtration protection device is in sewage discharge mode.

[0031] The tightness of the fit between the flip cover 20 and the second opening 103 is controlled by adjusting the tolerance value of the fit between the flip cover 20 and the second opening 103.

[0032] For example, when the water pressure is P' or the water flow rate is Q', the flip cover 20 keeps the second opening 103 closed, which is the filtration mode; when the water pressure is P'' or the water flow rate is Q'', P'' > P', Q'' > Q', the flip cover 20 keeps the second opening 103 open, which is the sewage discharge mode.

[0033] For example, P'' = 2P'.

[0034] It should be noted that, in order to achieve impurity filtration, the diameter of the first filter mesh 104 is smaller than the diameter of the first opening 102, and the diameter of the second filter mesh 201 is smaller than the diameter of the first opening 102, thereby intercepting impurities.

[0035] In this embodiment of the present invention, the filter body 10 is rotatably connected to a flip cover 20 at the second opening 103.

[0036] See Figures 1 to 3 The filter body 10 is rotatably connected to the flip cover 20 at the second opening 103 via a pin.

[0037] The pin is located at the upper part of the second opening 103. In this case, when the flip cover 20 opens the second opening 103, the flip cover 20 rotates upward around the pin.

[0038] Of course, the pin can also be set to the side of the second opening 103. In this case, when the flip cover 20 opens the second opening 103, the flip cover 20 rotates to the side around the pin.

[0039] Of course, the pin can also be set at the lower part of the second opening 103. In this case, when the flip cover 20 opens the second opening 103, the flip cover 20 rotates downward around the pin.

[0040] In this embodiment of the utility model, the filter body 10 is arranged in the horizontal direction; the first opening 102 and the second opening 103 are arranged at the same height, or the second opening 103 is arranged at a higher position than the first opening 102.

[0041] See Figures 1 to 3 The first opening 102 and the second opening 103 are set at the same height. When the flip cover 20 closes the second opening 103, water enters the filter body 10 from the first opening 102 and flows out through the first filter mesh 104 and the second filter mesh 201.

[0042] When the second opening 103 is positioned higher than the first opening 102, if the flip cover 20 closes the second opening 103, the installation object is a water tank structure, and the water level in the second cavity 401 inside the water tank body 40 is lower than the lowest position of the second filter mesh 201, water enters the filter body 10 from the first opening 102 and flows out through the first filter mesh 104. If the water level in the second cavity 401 inside the water tank body 40 is higher than the lowest position of the second filter mesh 201, water enters the filter body 10 from the first opening 102 and flows out through the first filter mesh 104 and the second filter mesh 201.

[0043] In this embodiment of the utility model, the filter body 10 is provided with an installation step 105, and the filter body 10 is detachably connected to the installation object (e.g., a water tank structure) through the installation step 105; the pipeline filter protection device also includes a sealing ring 30, which is sleeved on the outside of the installation step 105. The sealing ring 30 can increase the sealing between the filter body 10 and the installation object (e.g., a water tank structure) and prevent water inside the installation object (e.g., a water tank structure) from leaking to the outside of the installation object through the installation gap between the filter body 10 and the installation object.

[0044] The sealing ring 30 is a silicone sealing ring or a rubber sealing ring. Of course, the sealing ring 30 can also be made of other materials, depending on the specific application scenario.

[0045] In this embodiment of the present invention, both the first filter mesh 104 and the second filter mesh 201 are rhomboid, thereby giving the filter body 10 and the flip cover 20 a large opening ratio and a small resistance. Furthermore, the first filter mesh 104 has a small impact on the rigidity of the filter body 10, and the second filter mesh 201 has a small impact on the rigidity of the flip cover 20.

[0046] Multiple first filter meshes 104 are arranged at intervals along the length and circumferential direction of the filter body 10, and adjacent rows or columns of first filter meshes 104 are staggered to improve the opening rate; multiple second filter meshes 201 are arranged at intervals along the radial direction and perpendicular to the radial direction of the flip cover 20, and adjacent rows or columns of second filter meshes 201 are staggered to improve the opening rate.

[0047] The number of first filter mesh 104 and second filter mesh 201 is at least two.

[0048] In this embodiment of the utility model, a connector 106 is provided at the first end of the filter body 10, and the connector 106 is located near the first opening 102; the inner side wall of the connector 106 is provided with an internal thread for connecting the water inlet pipe, or the outer side wall of the connector 106 is provided with an external thread for connecting the water inlet pipe.

[0049] Since the filter body 10 needs to be connected to a pipeline assembly, such as the filter body 10 needs to be connected to an inlet pipe to achieve water intake, the inlet pipe is connected using connector 106 to facilitate the installation and removal of the pipeline filter protection device.

[0050] Example 2 See Figures 1 to 4 This utility model discloses a water tank structure, including any of the above-mentioned pipeline filtration protection devices.

[0051] The water tank structure of this utility model adopts the above-mentioned pipeline filtration protection device, which can filter impurities, thereby extending the service life of the water tank structure and improving the user's product experience.

[0052] In this embodiment of the utility model, the water tank structure further includes a water tank body 40, the interior of which has a second cavity 401; the side wall of the water tank body 40 is provided with a mounting hole 402 for mounting a filter body 10, the first end of the filter body 10 is located outside the water tank body 40, and the second end of the filter body 10 is located inside the second cavity 401; the bottom of the water tank body 40 is provided with a drain outlet 403, which is used to communicate with a drain pipe 50.

[0053] In this embodiment of the utility model, a drain port 404 is provided at the bottom of the water tank body 40, and the drain port 404 is used to connect with the drain pipe 60.

[0054] Depending on the actual application, a switch valve is installed on the drain outlet 403 and / or the drain pipe 50, and a switch valve is installed on the sewage outlet 404 and / or the sewage pipe 60.

[0055] In this embodiment of the utility model, the water tank structure further includes a flow monitoring unit 70, which includes a first flow meter 701, a second flow meter 702 and a third flow meter 703. The first flow meter 701 is disposed at the first opening 102, the second flow meter 702 is disposed at the first filter mesh 104, and the third flow meter 703 is disposed at the drain outlet 403.

[0056] The first flow meter 701, the second flow meter 702, and the third flow meter 703 can all be existing flow meters. The first flow meter 701, the second flow meter 702, and the third flow meter 703 are all electrically connected to the flow monitoring unit 70 or connected via electrical signals. The first flow meter 701, the second flow meter 702, and the third flow meter 703 all transmit the detected flow signals to the flow monitoring unit 70.

[0057] Since there are a large number of first filter mesh holes 104, second flow meters 702 can be installed at multiple different locations of the first filter mesh holes 104.

[0058] For example, the flow rate detected by the first flow meter 701 is Q1, the average of the flow rates detected by multiple second flow meters 702 is Q2, and the flow rate detected by the third flow meter 703 is Q3.

[0059] When the value of Q2 is lower than the predetermined value, that is, when the water flow from the filter body 10 is detected to be small, it proves that there are more impurities entering the first cavity 101 of the filter body 10, which clogs the first filter mesh 104, or the first filter mesh 104 near the second flow meter 702 is clogged by impurities. At this time, the flip cover 20 can be opened by increasing the water pressure or increasing the water flow. At this time, the pipeline filter protection device is in the sewage discharge mode, and the sewage discharge port 404 and / or sewage discharge pipe 60 are opened for sewage discharge, thereby improving the customer experience and extending the service life of the unit.

[0060] When the value of Q2 is greater than or equal to a predetermined value, that is, when the water flow from the filter body 10 is detected to be relatively normal, it proves that there are fewer impurities in the first cavity 101 of the filter body 10. At this time, the pipeline filtration protection device is in filtration mode. Water enters the filter body 10 from the first opening 102 and then enters the second cavity 401 of the water tank body 40 through the first filter mesh 104, or water enters the filter body 10 from the first opening 102 and then enters the second cavity 401 of the water tank body 40 through the first filter mesh 104 and the second filter mesh 201.

[0061] Of course, users can also periodically open the flip cover 20 to clean and drain sewage by increasing water pressure or water flow, thereby improving customer experience and extending the service life of the unit.

[0062] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
