Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a mineral supplement device and a water purifier. Background Art

[0002] In the prior art, in order to meet the user's demand for mineral water, a water purifier usually has a filter element for compounding a single element placed at the rear inside the filter bottle of the water purifier. The filter element adopts a slow-release filter material. When the pure water filtered by the filter bottle passes through this stage of the filter element, the mineral elements in the filter element will slowly dissolve and release, so as to obtain the required mineral water. However, when the water purifier is in the standby state, due to the remaining water in the filter element, long-term immersion will cause the content of mineral elements in the water to increase at this time. But when using water normally, since the release of mineral elements is relatively slow, it is easy to cause insufficient mineral elements in the obtained water, and the stability of the content of mineral elements in the obtained mineral water cannot be guaranteed.

[0003] Therefore, there is an urgent need for a mineral supplement device and a water purifier to solve the above problems. Summary of the Utility Model

[0033] To make the technical problems solved by the present utility model, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0034] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0036] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0037] In the prior art, in order to meet the user's demand for mineral water, a filter element with a single compound element is usually placed at the rear inside the filter bottle of the water purifier. This filter element all uses slow-release filter materials. When the pure water filtered by the filter bottle passes through this stage of filter element, the mineral elements in the filter element will slowly dissolve and release, so as to obtain the required mineral water. However, when the water purifier is in the standby state, due to the remaining water in the filter element, long-term immersion will cause the content of mineral elements in the water to increase at this time. But when using water normally, since the release of mineral elements is relatively slow, it is easy to cause insufficient mineral elements in the obtained water, making it impossible to ensure the stability of the content of mineral elements in the obtained mineral water.

[0038] To solve the above problems, as Figure 1 shown, this embodiment provides a mineral supplement device 10. The mineral supplement device 10 includes a connecting pipeline 1, a mixing pipeline 2, and a liquid storage assembly 3. Among them, the water inlet of the connecting pipeline 1 is used to communicate with the pure water outlet 201 of the water purifier. The mixing pipeline 2 is communicated with the outlet of the connecting pipeline 1. The liquid storage assembly 3 is used to store the mineral solution. The liquid storage assembly 3 is communicated with the mixing pipeline 2, and the liquid storage assembly 3 is used to introduce the mineral solution into the mixing pipeline 2. The mineral supplement device 10 provided in this embodiment, as shown by the direction of the arrow in the figure, can make the pure water discharged from the pure water outlet 201 mix with the introduced mineral solution in the mixing pipeline 2 and then be discharged, so as to obtain the required mineral water and meet the water use requirements. In addition, the setting of the above-mentioned mineral supplement device 10 enables both the pure water and the mineral solution to be introduced into the mixing pipeline 2 for mixing to obtain the required mineral water, which can accurately ensure the content of mineral elements in the mineral water and ensure the stability of the content of mineral elements in the obtained mineral water. It should be noted that in this embodiment, the mineral solution refers to a concentrated solution containing mineral elements.

[0039] Optionally, in this embodiment, as Figure 1 shown, the liquid storage assembly 3 is communicated with the atmosphere. The connecting pipeline 1 includes an inlet section 11 and a contraction section 12 connected to each other. The inlet section 11 is communicated with the pure water outlet 201. The outlet of the contraction section 12 is communicated with the mixing pipeline 2. Along the flowing direction of the pure water in the connecting pipeline 1, the inner diameter dimension of the contraction section 12 gradually decreases. With the above setting, when the pure water discharged from the pure water outlet 201 flows into the connecting pipeline 1, since the inner diameter dimension of the contraction section 12 gradually decreases along the flowing direction of the pure water, the flow rate of the pure water in the connecting pipeline 1 gradually increases along the flowing direction of the pure water, so that a Venturi effect is generated at the part where the mixing pipeline 2 is communicated with the contraction section 12, resulting in a negative pressure at the part where the mixing pipeline 2 is communicated with the contraction section 12. And because the liquid storage assembly 3 is communicated with the atmosphere, the air pressure in the liquid storage assembly 3 is the atmospheric pressure. Therefore, the negative pressure suction generated at the part where the mixing pipeline 2 is communicated with the contraction section 12 will automatically suck the mineral solution in the liquid storage assembly 3 into the mixing pipeline 2, thus realizing the automatic mixing of the pure water and the mineral solution in the mixing pipeline 2. In addition, with the above setting, only when the connecting pipeline 1 introduces pure water into the mixing pipeline 2, a negative pressure will be generated at the part where the mixing pipeline 2 is communicated with the contraction section 12, and the mineral solution in the liquid storage assembly 3 will be automatically sucked into the mixing pipeline 2, effectively ensuring the stability of the content of mineral elements in the obtained mineral water and also ensuring the accuracy of the content of mineral elements in the mineral water.

[0040] Optionally, in this embodiment, the taper angle of the contraction section 12 is 19° to 23°. Specifically, the taper angle of the contraction section 12 can be 19°, 20°, 21°, 22°, or 23°. The above settings ensure that a sufficiently large negative pressure suction is generated at the connection part between the mixing pipeline 2 and the contraction section 12 to automatically suck the mineral solution in the liquid storage assembly 3 into the mixing pipeline 2.

[0041] Optionally, in this embodiment, as Figure 1 shown, the mixing pipeline 2 includes a connected mixing section 21 and a diffuser section 22. The water outlet of the contraction section 12 and the liquid storage assembly 3 are both connected to the mixing section 21. The mixing section 21 is used to mix the incoming pure water and mineral solution. Along the flow direction of the water in the mixing pipeline 2, the inner diameter of the diffuser section 22 gradually increases. The above structural design of the diffuser section 22 enables the pure water and the mineral solution to be evenly mixed in the mixing section 21 and flow towards the diffuser section 22. Along the flow direction of the water, the flow channel size in the diffuser section 22 gradually increases, so that the flow velocity of the water flow in the diffuser section 22 gradually decreases and slows down, thereby avoiding the turbulence phenomenon.

[0042] Optionally, in this embodiment, the taper angle of the diffuser section 22 is 8° to 15°. Specifically, the taper angle of the diffuser section 22 can be 8°, 9°, 10°, 11°, 12°, 13°, 14°, or 15°. The above settings effectively ensure that the flow velocity of the water flow in the diffuser section 22 gradually decreases and slows down, thereby better avoiding the turbulence phenomenon.

[0043] In this embodiment, as Figure 1 shown, the mixing section 21 includes a sequentially connected connecting section 211, a tapered pipe section 212, and a straight pipe section 213. Among them, the connecting section 211 is sleeved and fixed on the outer periphery of the contraction section 12. The liquid storage assembly 3 is connected to the connecting section 211. The water outlet of the contraction section 12 extends into the tapered pipe section 212. The straight pipe section 213 is connected to the diffuser section 22. Along the flow direction of the water in the mixing pipeline 2, the inner diameter of the tapered pipe section 212 gradually decreases. The above structural setting of the mixing section 21 enables the connecting pipeline 1 and the mixing pipeline 2 to be connected to form a Venturi tube, ensuring the reliability of the mixing section 21 to automatically suck the mineral solution in the liquid storage assembly 3 into the mixing pipeline 2. In addition, by extending the water outlet of the contraction section 12 into the tapered pipe section 212 and connecting the liquid storage assembly 3 to the connecting section 211, the pure water and the mineral solution flow towards the tapered pipe section 212 together along the water flow direction and are mixed at the tapered pipe section 212. Coupled with the gradually increasing flow velocity at the tapered pipe section 212, the mixing uniformity of the pure water and the mineral solution is effectively improved.

[0044] Optionally, in this embodiment, the taper angle of the conical pipe section 212 is greater than the taper angle of the diffuser section 22 and greater than the taper angle of the contraction section 12. The design of the taper angle of the conical pipe section 212 not only effectively shortens the extension length of the mixing section 21, reduces the extension size of the mixing section 21, but also ensures the volume of the conical pipe section 212 and the flow rate of the mixed water in the mixing section 21.

[0045] In this embodiment, an annular limiting protrusion 111 is provided on the outer peripheral wall of the inlet section 11. When the connecting section 211 is sleeved and fixed on the outer periphery of the contraction section 12, the outer end surface of the connecting section 211 abuts against the annular limiting protrusion 111, thereby realizing the positioning and installation of the connecting section 211 on the inlet section 11 and ensuring the reliability of the water outlet of the contraction section 12 extending into the conical pipe section 212.

[0046] In this embodiment, as Figure 1 shown, the liquid storage assembly 3 includes a liquid storage tank 31 and a delivery pipeline 32. Among them, the liquid storage tank 31 is used to store the mineral solution. The inlet of the delivery pipeline 32 extends into the liquid storage tank 31, and the outlet of the delivery pipeline 32 is connected to the mixing pipeline 2. When a negative pressure suction is generated at the part where the mixing pipeline 2 is connected to the contraction section 12, the mineral solution contained in the liquid storage tank 31 is discharged into the mixing pipeline 2 through the delivery pipeline 32. It should be noted that in this embodiment, the outlet of the delivery pipeline 32 is connected to the connecting section 211. Optionally, the delivery pipeline 32 and the mixing pipeline 2 can be integrally formed. Optionally, a communication port 311 communicating with the atmosphere is provided at the top of the liquid storage tank 31 to ensure the communication between the liquid storage tank 31 and the atmosphere.

[0047] It should be noted that in this embodiment, the inner diameter size of the delivery pipeline 32 is set as long as the negative pressure suction generated at the part where the mixing pipeline 2 is connected to the contraction section 12 is greater than the weight of the stored mineral solution extracted in the delivery pipeline 32, so as to ensure that the mixing pipeline 2 sucks the mineral solution contained in the liquid storage tank 31 into the mixing pipeline 2 through the delivery pipeline 32.

[0048] Optionally, in this embodiment, the liquid storage tank 31 and the delivery pipeline 32 are detachably connected. The above setting can replace the liquid storage tank 31 according to needs, so as to replace it with the mineral solution of the required mineral element, or it can also be replaced with the mineral solution containing multiple mineral elements according to needs, meeting the different needs of users.

[0049] Optionally, in other embodiments, the mineral supplement device 10 further includes a liquid pumping assembly. The liquid storage assembly 3 is in communication with the atmosphere, and the liquid pumping assembly is disposed on the delivery pipeline 32. The liquid pumping assembly is used to pump the mineral solution in the liquid storage tank 31 into the mixing pipeline 2. Specifically, the liquid pumping assembly may be a water pump, and the water pump is communicatively connected to the valve at the water usage end. When the user uses water, the valve at the water usage end is opened, and the liquid pumping assembly can operate according to the opening signal of the valve at the water usage end to timely pump the mineral solution into the mixing pipeline 2 to be mixed with the incoming pure water. When the user stops using water, the valve at the water usage end is closed, and the liquid pumping assembly can stop operating according to the closing signal of the valve at the water usage end.

[0050] As Figure 2 and Figure 3 shown, this embodiment also provides a water purifier. The water purifier provided in this embodiment includes a water purifier main body 20 and the above-mentioned mineral supplement device 10. The water purifier main body 20 is used to filter the incoming tap water into pure water, and a pure water outlet 201 is provided on the water purifier main body 20, so that the water inlet of the connection pipeline 1 is in communication with the pure water outlet 201 of the water purifier main body 20. By applying the above-mentioned mineral supplement device 10, the pure water discharged from the pure water outlet 201 and the incoming mineral solution are mixed in the mixing pipeline 2 and then discharged, thereby obtaining the required mineral water and meeting the water usage requirements. In addition, by applying the above-mentioned mineral supplement device 10, the pure water and the mineral solution are both introduced into the mixing pipeline 2 for mixing to obtain the required mineral water, which can accurately ensure the content of mineral elements in the mineral water and ensure the stability of the content of mineral elements in the obtained mineral water.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
