Description

Technical Field

[0001] This utility model relates to the field of faucet manufacturing technology, and in particular to a water filtration and outlet mechanism and outlet device. Background Technology

[0002] A filtered water outlet device is a dedicated water inlet connected to point-of-use water purification equipment (such as reverse osmosis (RO) machines and ultrafiltration (UF) machines), providing users with direct access to purified water. Most existing filtered water outlet devices only function as filters. However, with the increasing diversity of functions available, integrated outlet devices with adjustable water temperature are gaining popularity, eliminating the need for waiting and heat preservation associated with traditional kettles. Existing filtered water outlet devices with adjustable water temperature typically mix cold and heated filtered water, adjusting the ratio of cold to hot water according to the user's desired temperature. Steam is easily generated during the mixing process, requiring venting to prevent high pressure buildup within the outlet device. Current filtered water outlet devices require separate components for mixing cold and hot water and separating steam, resulting in a bulky and large device structure. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a water filtration outlet mechanism and outlet device, wherein the outlet device utilizes a water filtration outlet mechanism provided in this application. The water filtration outlet mechanism can simultaneously achieve the functions of mixing hot and cold filtered water and separating water vapor, and has a compact structure.

[0004] In a first aspect, a water filtration and outlet mechanism according to an embodiment of the present utility model includes: The mixing box is provided with a mixing chamber, a water outlet, a first water inlet channel and a second water inlet channel. Both the first water inlet channel and the second water inlet channel are connected to the mixing chamber, and the water outlet is connected to the bottom of the mixing chamber. The water outlet pipe is connected to the bottom side of the mixing box and is connected to the water outlet hole. The mixing box is also equipped with a first exhaust pipe, which runs through and connects to the bottom side of the mixing box, with the top of the first exhaust pipe located at the top of the mixing chamber.

[0005] A water filtration and outlet mechanism according to an embodiment of the present utility model has at least the following beneficial effects: Ambient temperature filtered water and high temperature filtered water are thoroughly mixed in the middle and bottom of the mixing chamber to obtain warm filtered water, which flows out through the outlet at the bottom of the mixing chamber. The high temperature filtered water entering the mixing chamber generates steam. Both ambient temperature and high temperature filtered water generate steam during and after mixing. Due to their low density and evaporation, this steam rises and accumulates at the top of the mixing chamber. As the steam accumulates and the pressure increases, it is discharged to the top of the first exhaust pipe located at the top of the mixing chamber, and then exits to the outside. The mixing of hot and cold filtered water and the separation of water vapor are both accomplished through the same water outlet mechanism, resulting in a compact structure that is smaller in size than existing water outlet mechanisms and has wider installation adaptability.

[0006] According to an embodiment of the present invention, a water filtration and outlet mechanism is provided in which a first exhaust pipe is adjacent to and spaced apart from the water outlet.

[0007] According to an embodiment of the present utility model, a water filtration outlet mechanism is provided in the mixing box, and a second exhaust pipe is provided inside the mixing box. The second exhaust pipe is adjacent to and spaced apart from the water outlet hole, and the second exhaust pipe and the first exhaust pipe are arranged opposite to each other on both sides of the water outlet hole.

[0008] According to an embodiment of the present utility model, a water filtration and outlet mechanism is provided, wherein the bottom side of the mixing box is also connected to an air guide cover, and a first air outlet channel is provided inside the air guide cover, and the first air outlet channel is connected to a first exhaust pipe.

[0009] According to an embodiment of the present invention, a water filtration and outlet mechanism is provided, wherein an air guide hood is spaced around the outside of the outlet pipe, and a first air outlet channel is formed between the air guide hood and the outlet pipe.

[0010] According to an embodiment of the present utility model, a water filtration and outlet mechanism is provided with a vent hole on the side wall of the first exhaust pipe, and a second air outlet channel is also provided in the mixing box, which is connected to the first exhaust pipe through the vent hole.

[0011] According to an embodiment of the present invention, a water filtration and outlet mechanism is provided in a mixing box, wherein a first partition and a second partition are provided inside the mixing box, and the first partition and the second partition divide the inner cavity of the mixing box into a first water inlet channel, a second water inlet channel and a second air outlet channel.

[0012] According to an embodiment of the present invention, a water filtration and outlet mechanism further includes a first water inlet pipe and a second water inlet pipe, which pass through and are connected to the side wall of the mixing box. The first water inlet pipe is connected to a first water inlet channel, and the second water inlet pipe is connected to a second water inlet channel.

[0013] Secondly, according to an embodiment of the present utility model, a water outlet device applies the above-mentioned water filtration outlet mechanism and further includes a faucet housing and a faucet top plate. The water filtration outlet mechanism is disposed inside the faucet housing, and the faucet top plate is matched and connected to the upper side of the faucet housing.

[0014] Ambient temperature filtered water and high temperature filtered water are thoroughly mixed in the middle and bottom of the mixing chamber to obtain warm filtered water, which flows out through the outlet at the bottom of the mixing chamber. The high temperature filtered water entering the mixing chamber generates steam. Both ambient temperature and high temperature filtered water generate steam during and after mixing. Due to their low density and evaporation, this steam rises and accumulates at the top of the mixing chamber. As the steam accumulates and the pressure increases, it is discharged to the top of the first exhaust pipe located at the top of the mixing chamber, and then exits to the outside. The mixing of hot and cold filtered water and the separation of water vapor are both accomplished through the same water outlet mechanism, resulting in a compact structure that is smaller in size than existing water outlet mechanisms. This makes the overall size of the water outlet device smaller and allows for installation in a wider range of installation scenarios.

[0015] According to an embodiment of the present utility model, a water outlet device further includes a tap water outlet mechanism, which is disposed inside the faucet housing and located on one side of the filtered water outlet mechanism.

[0023] Reference Figures 1 to 5This utility model provides a filtered water outlet mechanism, including a mixing box 100 and an outlet pipe 200. The mixing box 100 is provided with a mixing chamber 130, an outlet hole 114, a first inlet channel 140, and a second inlet channel 150. Both the first inlet channel 140 and the second inlet channel 150 are connected to the mixing chamber 130, and the outlet hole 114 is connected to the bottom of the mixing chamber 130. Optionally, heated filtered water enters from one end of the first inlet channel 140 and then flows out from the other end of the first inlet channel 140 to the mixing chamber 130. Room temperature filtered water enters from one end of the second inlet channel 150 and then flows out from the other end of the second inlet channel 150 to the mixing chamber 130. The mixing chamber 130 is used to mix the room temperature filtered water with the heated filtered water, and the mixed warm water flows out from the outlet hole 114.

[0024] In some embodiments, room temperature filtered water enters from one end of the first water inlet channel 140 and then flows out from the other end of the first water inlet channel 140 to the mixing chamber 130. Heated filtered water enters from one end of the second water inlet channel 150 and then flows out from the other end of the second water inlet channel 150 to the mixing chamber 130.

[0025] Specifically, refer to Figure 2 The mixing box 100 consists of a box body 110 and a cover 120, which are matched and fitted together. The cover 120 can close onto the upper side of the box body 110 to form a mixing chamber 130, a first water inlet channel 140, and a second water inlet channel 150. The mixing box 100 consists of a box body 110 and a cover 120, which facilitates the separate manufacturing of the box body 110 and the cover 120, greatly simplifying the manufacturing process and improving manufacturing efficiency.

[0026] The water outlet pipe 200 is connected to the bottom side of the mixing box 100 and is connected to the water outlet hole 114. Warm water flowing out of the water outlet hole 114 flows into the water outlet pipe 200 and flows out to the outside under the guidance of the water outlet pipe 200.

[0027] The mixing tank 100 is also provided with a first exhaust pipe 111, which passes through and is connected to the bottom side of the mixing tank 100. The top end of the first exhaust pipe 111 is located at the upper part of the mixing chamber 130. The first exhaust pipe 111 connects the mixing chamber 130 to the outside of the bottom side of the mixing tank 100, so that the steam in the mixing chamber 130 can be discharged to the outside through the first exhaust pipe 111.

[0028] The ambient temperature filtered water and the high temperature filtered water entering the mixing chamber 130 through the first inlet channel 140 and the second inlet channel 150 are thoroughly mixed in the middle and bottom of the mixing chamber 130 to obtain warm filtered water, which flows out through the outlet hole 114 at the bottom of the mixing chamber 130. The high temperature filtered water entering the mixing chamber 130 generates steam. Both the ambient temperature filtered water and the high temperature filtered water generate steam during and after mixing. Due to their low density and evaporation, this steam accumulates upwards in the upper part of the mixing chamber 130. As the steam accumulates and the pressure increases, it can be discharged to the top of the first exhaust pipe 111 located at the top of the mixing chamber 130, and then discharged to the outside through the first exhaust pipe 111. The mixing of hot and cold filtered water and the separation of water vapor are both accomplished through the same water outlet mechanism, which is compact in structure, smaller in size than existing water filtration outlet mechanisms, and has wider installation adaptability.

[0029] According to some embodiments of this application, refer to Figure 2 and Figure 4 The first exhaust pipe 111 and the water outlet 114 are adjacent to each other and spaced apart. Specifically, the first exhaust pipe 111 and the water outlet 200 are adjacent to each other and spaced apart. The projection of the first exhaust pipe 111 on the housing 110 is located on the adjacent side of the projection of the water outlet 200 on the housing 110. The lower port of the first exhaust pipe 111 is adjacent to the lower port of the water outlet 200. The steam discharged from the lower port of the first exhaust pipe 111 will increase the humidity around the first exhaust pipe 111, making it easy for water droplets to condense. The lower port of the first exhaust pipe 111 is adjacent to the lower port of the water outlet 200. The steam discharged from the lower port of the first exhaust pipe 111 will condense water droplets near the lower port of the water outlet 200, thereby reducing the wetted area of ​​the water filtration mechanism and making it easier to manage the dripping water generated by the steam condensation and the residual dripping water in the water outlet 200.

[0030] Furthermore, referring to Figure 2 and Figure 4 The mixing tank 100 is also equipped with a second vent pipe 112, which is adjacent to and spaced apart from the water outlet 114. The second vent pipe 112 and the first vent pipe 111 are positioned opposite each other on both sides of the water outlet 114. Specifically, the second vent pipe 112 and the first vent pipe 111 are mirror-symmetrical. The second vent pipe 112 also passes through and connects to the bottom side of the mixing tank 100, and its top end is located at the upper part of the mixing chamber 130. The second vent pipe 112 further improves the efficiency of steam removal.

[0031] According to some embodiments of this application, refer to Figure 1 , Figure 3 and Figure 5The bottom side of the mixing box 100 is also connected to a vent 300. The vent 300 has a first venting channel 310 inside, which is connected to the first exhaust pipe 111. The vent 300 guides the steam in the first exhaust pipe 111, achieving centralized steam discharge. It also allows the steam to condense into water droplets at the lower end of the vent 300, further reducing the wetted area of ​​the filtered water outlet mechanism.

[0032] Furthermore, referring to Figure 1 , Figure 3 and Figure 5 The air guide hood 300 is spaced around the outside of the water outlet pipe 200, as shown in the reference. Figure 5 A first air outlet channel 310 is formed between the air guide hood 300 and the water outlet pipe 200. Specifically, the air guide hood 300 has a funnel structure, and the water outlet pipe 200 is located inside the funnel-shaped air guide hood 300. The water outlet pipe 200 and the air guide hood 300 do not contact each other, forming an annular first air outlet channel 310. Specifically, the first exhaust pipe 111 and the second exhaust pipe 112 are both connected to the first air outlet channel 310. The annular first air outlet channel 310 guides steam to be discharged from the periphery of the water outlet pipe 200, further reducing the wetted area of ​​the filtered water outlet mechanism. Moreover, the steam easily condenses into water droplets at the lower end of the water outlet pipe 200 and drips down, effectively reducing the loss of filtered purified water.

[0033] According to some embodiments of this application, refer to Figure 2 and Figure 5 The first exhaust pipe 111 has a vent hole 113 on its side wall, and the mixing box 100 also has a second exhaust channel 160, which is connected to the first exhaust pipe 111 through the vent hole 113. Steam passing through the first exhaust pipe 111 can be discharged into the second exhaust channel 160 through the vent hole 113, further improving the efficiency of steam discharge.

[0034] Furthermore, referring to Figure 4 The mixing box 100 is provided with a first partition 115 and a second partition 116, which divide the inner cavity of the mixing box 100 into a first water inlet channel 140, a second water inlet channel 150, and a second air outlet channel 160. Specifically, the second air outlet channel 160 is located on one side of the second water inlet channel 150, and the first water inlet channel 140 is located on the opposite side of the second water inlet channel 150. The first water inlet channel 140, the second water inlet channel 150, and the second air outlet channel 160 are arranged in the same direction. Specifically, when the cover 120 is fitted onto the upper side of the box body 110, the top of the second partition 116 is fitted and connected to the lower side of the cover 120 to separate the second air outlet channel 160 from the second water inlet channel 150, the first water inlet channel 140, and the mixing chamber 130.

[0035] According to some embodiments of this application, refer to Figure 2 It also includes a first inlet pipe 400 and a second inlet pipe 500, which pass through and are connected to the side wall of the mixing box 100. The first inlet pipe 400 is connected to the first inlet channel 140, and the second inlet pipe 500 is connected to the second inlet channel 150. Specifically, the first inlet pipe 400 and the second inlet pipe 500 are respectively connected to a normal temperature filtered water source and a high temperature filtered water source, and guide the normal temperature filtered water and the high temperature filtered water into the first inlet channel 140 and the second inlet channel 150, respectively.

[0036] It is understood that in some other embodiments, the first water inlet pipe 400 and the second water inlet pipe 500 may also guide room temperature filtered water and high temperature filtered water into the second water inlet channel 150 and the first water inlet channel 140, respectively.

[0037] It is understood that, in some other embodiments, reference is made to... Figure 2 It also includes a third exhaust pipe 600, which penetrates and connects to the side wall of the mixing box 100 and is connected to the second venting channel 160. Specifically, the third exhaust pipe 600 can be connected to a filtered water storage bottle (not shown in the figure) through a pipe, and steam can be discharged into the filtered water storage bottle through the second venting channel 160 and the third exhaust pipe 600 to reduce the loss of filtered water.

[0038] As a preferred embodiment, ambient temperature filtered water enters from one end of the second inlet channel 150. The ambient temperature filtered water flowing in the second inlet channel 150 can cool the second partition 116, thereby cooling the second outlet channel 160 located on the other side of the second partition 116. This allows the high-temperature steam to be cooled in advance, thereby reducing the temperature of the steam returning to the filtered water storage bottle and increasing the amount of high-temperature steam condensation, thus reducing the temperature of the filtered water stored in the high-temperature steam filtered water storage bottle.

[0039] It is understood that, in some other embodiments, reference is made to... Figure 4 The mixing box 100 is further provided with a third partition 117, which is located at one end of the first water inlet channel 140 near the mixing chamber 130. A first vent pipe 111 is located at one end of the second water inlet channel 150 near the mixing chamber 130. A mixing channel is formed between the first vent pipe 111 and the third partition 117. (Refer to...) Figure 4 Under the action of the first exhaust pipe 111 and the third partition 117, the ambient temperature filtered water and the high temperature filtered water flowing in from the first water inlet channel 140 and the second water inlet channel 150 merge and flow into the mixing chamber 130 in the mixing channel, which can improve the mixing efficiency of the ambient temperature filtered water and the high temperature filtered water, thereby making the temperature of the filtered water flowing out of the outlet pipe 200 more constant.

[0040] This application also provides a water outlet device that utilizes a water filtration outlet mechanism of this application, as described above. Figure 6 It also includes a faucet housing 700 and a faucet top plate 710. The water filter outlet mechanism is disposed within the faucet housing 700, and the faucet top plate 710 is matched and connected to the upper side of the faucet housing 700. The faucet housing 700 and the faucet top plate 710 cooperate to form an installation cavity, and the water filter outlet mechanism is disposed within the installation cavity, which can provide good protection for the water filter outlet mechanism.

[0041] According to some embodiments of this application, refer to Figure 6 The water outlet device also includes a tap water outlet mechanism 800, which is located inside the faucet housing 700 and situated to one side of the filtered water outlet mechanism. The water outlet device can provide both filtered water and tap water, offering convenience for users.

[0042] The ambient temperature filtered water and the high temperature filtered water entering the mixing chamber 130 through the first inlet channel 140 and the second inlet channel 150 are thoroughly mixed in the middle and bottom of the mixing chamber 130 to obtain warm filtered water, which flows out through the outlet hole 114 at the bottom of the mixing chamber 130. The high temperature filtered water entering the mixing chamber 130 generates steam. Both the ambient temperature filtered water and the high temperature filtered water generate steam during and after mixing. Due to their low density and evaporation, this steam accumulates upwards in the upper part of the mixing chamber 130. As the steam accumulates and the pressure increases, it can be discharged to the top of the first exhaust pipe 111 located at the top of the mixing chamber 130, and then discharged to the outside through the first exhaust pipe 111. The mixing of hot and cold filtered water and the separation of water vapor are both accomplished through the same water outlet mechanism, which is compact and smaller in size than existing filtered water outlet mechanisms, thus making the overall size of the filtered water outlet device smaller and allowing it to be installed in more different installation scenarios.
