Description

Technical Field

[0001] This invention relates to the field of water purifiers, and more specifically to an explosion-proof water purifier. Background Technology

[0002] With the improvement of living standards, more and more families are choosing to install faucet water purifiers on their taps to improve the quality of household water. Faucet water purifiers are small in size and have the advantages of being easy to install and maintain. However, existing faucet water purifiers still have many defects. For example, the water purifier disclosed in Chinese invention patent application CN 218267292 U includes a filter element water circuit control mechanism, wherein the water circuit switching mechanism can connect the tap water inlet to the tap water shower outlet; when turned to the water purification setting, the tap water inlet is connected to the water inlet passage (41). This structure is prone to water hammer impact in the internal cavity when the filter element is clogged after long-term use, causing the water purifier to be cracked by water pressure.

[0003] In view of this, the present invention provides an explosion-proof water purifier. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an explosion-proof water purifier.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] An explosion-proof water purifier includes a water distribution mechanism, which includes a water distribution plate and a water outlet plate, the water distribution plate and the water outlet plate cooperating to form an inner cavity and an outer cavity.

[0007] The inner cavity is equipped with a filter element, and the outer cavity is arranged around the inner cavity.

[0008] The inner cavity and outer cavity are switched by rotation to connect to the upstream water inlet.

[0009] The inlet is equipped with a rubber cup, and the outlet of the rubber cup expands elastically to release water when the flow in the inner cavity is obstructed and the cavity pressure rises.

[0010] Furthermore, when the outlet end of the leather cup is connected to the water passage of the inner cavity or the outer cavity, the leather cup partially blocks the inlet of the other water passage;

[0011] During the process of switching the water outlet of the leather cup from the water path of the inner cavity to the water path of the outer cavity, or during the process of switching the water outlet of the leather cup from the water path of the outer cavity to the water path of the inner cavity, the water outlet of the leather cup remains connected to the water path of the inner or outer cavity.

[0012] Furthermore, the diaphragm is installed in the water inlet body, and the water outlet end face of the water inlet body is lower than the water outlet end face of the diaphragm.

[0013] Furthermore, a discharge gap is provided between the water outlet end face of the water inlet body and the water inlet end face of the water distribution plate.

[0014] Furthermore, when the water purifier is working, the sealing end face of the water outlet of the diaphragm abuts against the water inlet end face of the water distribution plate, and the water flow is introduced into the water distribution mechanism from the flow cavity of the diaphragm; when the water pressure is too high and the diaphragm is opened, the water flow enters the outer cavity from the drain gap and flows out.

[0015] Furthermore, the water outlet of the leather cup has a short side and a long side forming from the outer circumferential sealing edge of the leather cup, and the outer circumferential sealing edge located on the short side is expanded under a predetermined water pressure.

[0016] Furthermore, the volume of the water passage in the inner cavity is greater than the volume of the water passage surrounding the inner cavity region of the outer cavity.

[0017] Furthermore, the upper end of the filter element is provided with a filter element cover, and the end face of the filter element cover near the outer edge is provided with a filter element cover water inlet hole. The lower end of the filter element cover water inlet hole is provided with a guide plate near the filter element cover water outlet. The guide plate prevents water from directly impacting the filter element.

[0018] Furthermore, the guide plate has a flow-diffusing block on the opposite side.

[0019] Furthermore, the filter element is provided with a support plate at its upper or lower end, and the support plate has the function of filtering or supporting the filter element.

[0020] The above technical solution has the following beneficial effects:

[0021] This invention relates to an explosion-proof water purifier. The inlet of the purifier features a rubber cup, whose outlet elastically expands to release water when the internal cavity pressure rises due to poor flow. Specifically, a drainage gap is provided between the outlet face of the inlet and the inlet face of the distribution plate. This gap not only provides deformation space for the outer wall of the rubber cup, but also allows the cup to be pushed open by water pressure when the water pressure at the outlet exceeds a design value. Furthermore, during operation, the sealed end face of the outlet of the rubber cup abuts against the inlet face of the distribution plate, guiding water flow from the flow cavity of the rubber cup into the distribution mechanism. When the water pressure is too high and the rubber cup is pushed open, water flows out through the drainage gap into the outer cavity, preventing water from clogging the internal cavity and affecting the use of the water purifier.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0044] See Figure 1-2 An explosion-proof water purifier includes a water distribution mechanism, which includes a water distribution plate 2 and a water outlet plate 3, which cooperate to form an inner cavity 4 and an outer cavity 5.

[0045] The inner cavity 4 is provided with a filter element 6, and the outer cavity 5 is arranged around the inner cavity 4.

[0046] The inner cavity 4 and the outer cavity 5 are switched by rotation to connect to the upstream water inlet 7.

[0047] The inlet 7 is equipped with a leather cup 1. When the flow in the inner cavity 4 is obstructed and the cavity pressure rises, the outlet end of the leather cup 1 elastically expands to release water.

[0048] As a further explanation of this embodiment, when the water outlet of the diaphragm is connected to the water passage of the inner cavity or the outer cavity, the diaphragm partially blocks the inlet of the other water passage. During the process of switching the water outlet of the diaphragm from the water passage of the inner cavity to the water passage of the outer cavity, or vice versa, the water outlet of the diaphragm remains connected to the water passage of the inner or outer cavity.

[0049] For details, please refer to Figure 13 At this time, the water outlet of the diaphragm is connected to the water passage of the inner cavity, ensuring that water can enter the water passage of the outer cavity when the diaphragm expands and releases pressure. See also Figure 16 Similarly, the water outlet of the aforementioned leather cup, which connects to the water passage of the outer cavity, achieves the same effect.

[0050] For details, please refer to Figure 14 and Figure 15 During the process of switching the water outlet of the leather cup from the water passage of the inner cavity to the water passage of the outer cavity, the water outlet of the leather cup remains connected to the water passage of the inner or outer cavity to avoid water hammer impact.

[0051] As a further explanation of this embodiment, the leather cup 1 is installed inside the water inlet body 8, and the water outlet end face of the water inlet body 8 is lower than the water outlet end face of the leather cup 1.

[0052] As a further explanation of this embodiment, the water inlet body 8 and the water distribution mechanism are provided with an outer shell 10.

[0053] As a further explanation of this embodiment, a drainage gap 9 is provided between the water outlet end face 81 of the water inlet body and the water inlet end face of the water distribution plate. The drainage gap 9 not only provides deformation space for the outer wall of the diaphragm 1, but also allows the diaphragm 1 to be pushed open by the water pressure when the water pressure at the outlet of the diaphragm 1 exceeds the design value. Moreover, when the water purifier is working, the sealing end face 14 of the water outlet of the diaphragm abuts against the water inlet end face of the water distribution plate, and the water flow is guided from the flow cavity 13 of the diaphragm 1 into the water distribution mechanism; when the water pressure is too high and the diaphragm 1 is pushed open, the water flow enters the outer cavity 5 through the drainage gap 9 and flows out, preventing the water flow from clogging the inner cavity 4 and affecting the use of the water purifier.

[0054] As a further explanation of this embodiment, the water outlet of the leather cup 1 and the outer circumferential sealing edge of the leather cup 1 are formed with a short side and a long side, and the outer circumferential sealing edge located on the short side is opened up under a predetermined water pressure.

[0055] As a further explanation of this embodiment, the water passage volume of the inner cavity 4 is greater than the water passage volume of the area surrounding the inner cavity 4 by the outer cavity 5.

[0056] As a further explanation of this embodiment, the upper end of the filter element 6 is provided with a filter element cover 61, the end face of the filter element cover 61 near the outer edge is provided with a filter element cover water inlet hole 62, and the lower end of the filter element cover water inlet hole 62 near the water outlet of the filter element cover 61 is provided with a guide plate 63, the guide plate 63 prevents water from directly hitting the filter element 6.

[0057] As a further explanation of this embodiment, the guide plate 63 is provided with a flow-diffusing block 64 on the opposite side.

[0058] As a further explanation of this embodiment, the filter element 6 is provided with a support plate 65 at its upper or lower end, and the support plate 65 has the function of filtering or supporting the filter element 6.

[0059] As a further explanation of this embodiment, the water outlet plate 3 is provided with a support block 66. The support block 66 is used to support the filter element 6.

[0060] As a further explanation of this embodiment, the leather cup 1 includes a water inlet end 11, a water outlet end 12, and a flow passage cavity 13 located between the water inlet end 11 and the water outlet end 12 of the leather cup.

[0061] The inner wall of the flow cavity 13 is provided with a hydraulic pressure-bearing surface 15, which transmits water pressure to the end face of the outlet end 12 of the diaphragm, making the end face of the outlet end of the diaphragm 1 tightly sealed against the inlet end face of the water distribution plate. A pressure deformation zone 16 is provided on the outlet end 12 of the diaphragm. The flow cavity 13 collects the water flow from the inlet end 11 of the diaphragm and then passes it through the pressure deformation zone 16 into the outlet end 12 of the diaphragm. The structure of this invention allows the sealing end face 14 of the outlet end of the diaphragm to press against the inlet end face of the water distribution plate through water pressure, making installation simpler and more convenient, and ensuring more stable water pressure.

[0062] As a further explanation of this embodiment, the hydraulic pressure-bearing surface 15 is located above the water outlet end 12 of the diaphragm cup. The area of ​​the hydraulic pressure-bearing surface 15 is larger than the area of ​​the sealing end face, so that the diaphragm cup 1 has sufficient pressure to fit against the sealing surface, ensuring reliable sealing.

[0063] As a further explanation of this embodiment, the pressure deformation zone 16 controls the flow area above the water outlet 12 of the diaphragm through elastic deformation under water pressure. Since the diaphragm 1 is made of flexible material, and the water outlet of the diaphragm 1 is positioned off-center from the hydraulic pressure-bearing surface, uneven water pressure is generated above the water outlet of the diaphragm 1, causing elastic deformation at the upper end of the water outlet. This elastic deformation causes a change in the flow area, thereby controlling the water flow rate. Furthermore, preferably, the pressure deformation zone 16 is provided with an upwardly protruding baffle 161, which tilts inward toward the water outlet 12 of the cup under water pressure, and the baffle 161 is used to control the flow area of ​​the upper part of the water outlet 12 of the cup; or the pressure deformation zone 16 is provided with a downwardly protruding recess 162, the side wall of the recess 162 near the water outlet 12 of the cup tilts inward toward the water outlet 12 of the cup under water pressure, and the recess 162 is used to control the flow area of ​​the upper part of the water outlet 12 of the cup. By setting the pressure deformation zone 16, which is provided with an upwardly protruding baffle 161 or a downwardly protruding recess 162, the water outlet 12 of the cup tilts inward under water pressure, thereby controlling the flow area of ​​the upper part of the water outlet 12 of the cup, and further achieving the effect of flow control.

[0064] As a further explanation of this embodiment, the inlet end 11 of the aerator cup is provided with a concave ring 17 for installing a filter screen or a flow controller. The concave ring 17 forms the installation position for the filter screen or flow controller. Generally, the aerator in this embodiment only needs a filter screen; an additional flow controller is not required. The flow area at the upper part of the outlet end 12 of the aerator cup can be controlled by the enclosure 161 and the recess 162 of the pressure deformation zone 16 of the aerator cup 1, thereby achieving the effect of flow control.

[0065] As a further explanation of this embodiment, the lower part of the leather cup 1 is provided with a groove 18 or a protrusion 19 to restrict axial rotation.

[0066] As a further explanation of this embodiment, the diaphragm 1 is made of flexible rubber such as NBR, EPDM, or silicone. Experiments have shown that when the diaphragm's hardness is 50 (Brownian hardness), the water pressure at the diaphragm's inlet can be controlled to expand and release at 0.6 MPa. When the diaphragm's hardness is 65 (Brownian hardness), the water pressure at the diaphragm's inlet can be controlled to expand and release at 0.8 MPa. When the diaphragm's hardness is 85 (Brownian hardness), the water pressure at the diaphragm's inlet can be controlled to expand and release at 0.9 MPa. When the diaphragm's hardness is 90 (Brownian hardness), the water pressure at the diaphragm's inlet can be controlled to expand and release at 1 MPa.

[0067] As a further explanation of this embodiment, the sealing end face 14 of the water outlet of the leather cup is waist-shaped.

[0068] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
