DETAILED DESCRIPTION

[0035] Combine the following Figure 1-12 The utility model is described in detail.

[0036] The utility model provides a descaling bubbler 10, comprising a body, a pressure stabilizing member 50 and a guide rod device installed in the body, specifically:

[0037] The main body is provided with a water inlet surface and a water outlet surface, the water inlet surface is provided with a guide surface 201 which is recessed along the water outlet direction, the guide surface 201 is provided with a plurality of first water inlets 801, and a second water inlet 802 is provided at the lowest point of the guide surface 201; the water outlet surface is provided with a first water outlet 901 and a second water outlet 902, and a first water outlet channel connecting the first water inlet 801 and the first water outlet 901 and a second water outlet channel connecting the second water inlet 802 and the second water outlet 902 are provided in the main body.

[0038] A pressure stabilizer 50 is provided in the first water outlet channel, and the pressure stabilizer 50 adjusts the size of the water flow cross-sectional area at some positions in the first water outlet channel based on the pressure of the incoming water; a guide rod device is provided in the second water outlet channel, and the guide rod device can move along the axial direction of the second water outlet channel to close or open the second water inlet 802.

[0039] When in use, the guide rod device closes the second water inlet 802 under the action of water pressure or its own gravity, so that the inlet water flows out from the first outlet channel, and impurities and dirt in the water are trapped on the water inlet surface. The guide rod device is driven to move by external force to open the second water inlet 802, so that dirt flows out from the second outlet 902 through the second outlet channel.

[0040] Therefore, the user can push the guide rod device by himself to discharge the descaling and complete the descaling process, without arranging maintenance personnel to come for maintenance, thereby reducing the user's use cost. Secondly, the pressure stabilizer 50 is placed in the first water outlet channel, which can stabilize the water flow in the first water outlet channel, reduce the possibility of water splashing and suction noise, and improve the user's use experience.

[0041] In this embodiment, an elastic member 70 is further included, and the elastic member 70 is sleeved outside the guide rod device, and one end of the elastic member 70 abuts against the guide rod device, and the other end of the elastic member 70 abuts against the body. When water is inlet, the guide rod device is pressed to overcome the elastic force of the elastic member 70 to close the second water inlet 802; when water is stopped, the guide rod device opens the second water inlet 802 under the elastic force of the elastic member 70.

[0042] Therefore, the guide rod device automatically opens the second water inlet 802 when the water is stopped by the elastic member 70, so that the dirt remaining on the water inlet surface automatically flows out from the second water outlet channel, that is, the dirt is discharged every time the water is stopped, reducing the user's extra operations. In other embodiments, the guide rod device can also be manually pushed to open the second water inlet 802 during the water inlet process, and at this time, water flows out of the first water outlet channel and the second water outlet channel at the same time.

[0043] In this embodiment, Figure 2 , Fig. 9 and Fig.10As shown, the main body includes a shell 40, a water combing member 30 and a filter 20 which are connected to each other in sequence. The space enclosed by the shell 40 and the water combing member 30 constitutes an air mixing chamber 1001, and the space enclosed by the water combing member 30 and the filter 20 constitutes a water dividing chamber 1002. The water dividing chamber 1002 is connected to the air mixing chamber 1001 through a plurality of water dividing holes 301 provided on the water combing member 30, thereby forming a first water outlet channel, so that the incoming water flow flowing through the water dividing holes 301 is evenly divided into multiple water flows, and the multiple water flows are evenly mixed with the air in the air mixing chamber 1001, thereby enhancing the bubbling effect of the outgoing water flow.

[0044] In this embodiment, Figure 9-10 As shown, the pressure stabilizer 50 is arranged in the water diversion chamber 1002, and the water diversion chamber 1002 has a buffer space for the deformation of the pressure stabilizer 50. The pressure stabilizer 50 is provided with a water hole 501, and the water hole 501 and the water combing member 30 form a flow limiting channel 110. The outer side of the pressure stabilizer 50 is fixed between the filter screen 20 and the water combing member 30. The pressure stabilizer 50 adjusts the water flow cross-sectional area of ​​the flow limiting channel 110 based on the pressure of the incoming water. Specifically, as Figure 4 As shown, the outer ring of the pressure stabilizer 50 is provided with a fixing portion 502, and the filter screen 20 and the water combing member 30 clamp the fixing portion 502, so that the pressure stabilizer 50 is fixed in the water diversion chamber 1002. The thickness of the fixing portion 502 is smaller than that of other positions of the pressure stabilizer 50, so that the pressure stabilizer 50 is easily deformed when impacted by water flow, thereby adjusting the water outlet cross-sectional area of ​​the first water outlet channel. Specifically, when the inlet water pressure is less than 0.2MPa, the pressure stabilizer 50 does not elastically deform, and when the inlet water pressure is greater than 0.2MPa, the pressure stabilizer 50 elastically deforms. The greater the water pressure, the greater the elastic deformation of the pressure stabilizer 50, until the pressure stabilizer 50 closes the first water outlet channel to the minimum.

[0045] In this embodiment, Figure 3 As shown, the filter screen 20 is provided with a guide surface 201, and the guide surface 201 is provided with a plurality of filter holes, the filter holes constitute the first water inlet 801, and each filter hole is connected to the water diversion chamber 1002. Figure 7-8 As shown, the housing 40 is provided with a first water outlet 901 and a second water outlet 902, the first water outlet 901 is connected to the gas mixing chamber 1001, and the second water outlet 902 is composed of a plurality of water outlet holes distributed on the water outlet surface, thereby dividing the water flow into a plurality of thin streams, and the housing 40 is also provided with a wrench position and an air suction hole 401 connected to the gas mixing chamber 1001. Further, a first annular wall 402 extending toward the filter 20 is provided at the opening of the first water outlet 901 facing the filter 20, and the water combing member 30 is provided with a mounting hole 302 for penetrating the first annular wall 402, and the internal space of the first annular wall 402 is connected to the second water inlet 802, thereby forming a second water outlet channel.

[0046] In this embodiment, the first annular wall 402 is provided with a positioning guide groove 4021 extending along the water outlet direction, and the outer side surface of the guide rod device is provided with a positioning protrusion 6021 slidably adapted to the positioning guide groove 4021. Specifically, the number of the positioning guide groove 4021 and the positioning protrusion 6021 is three. The radial dimension of the positioning protrusion 6021 is greater than the radial dimension of the second water inlet 802, so as to prevent the guide rod device from being separated from the second water inlet 802 under the elastic force of the elastic member 70.

[0047] In this embodiment, the elastic member 70 is a compression spring, which is sleeved on the outside of the first annular wall 402, and one end of the elastic member 70 abuts against the positioning protrusion 6021, and the other end abuts against the housing 40, thereby driving the guide rod device to move. Further, the guide rod device includes an upper guide rod 601 and a lower guide rod 602 connected to each other, one end of the upper guide rod 601 is provided with a cover body 6011 for closing the second water inlet 802, one end of the lower guide rod 602 protrudes out of the water surface, which is convenient for users to push, and the positioning protrusion 6021 is provided with the lower guide rod 602. Further, the cover body 6011 is provided with a sealing surface adapted to the guide surface 201 located at the edge of the second water inlet 802, thereby closing the second water inlet 802, and the first water inlet 801 is not provided at the position where the guide surface 201 is adapted to the sealing surface, thereby improving the sealing effect between the sealing surface and the guide surface 201.

[0048] The descaling bubbler 10 proposed in the present invention has the following principle:

[0049] In the water-filled state, Fig. 9 As shown, the guide rod device overcomes the elastic force of the elastic member 70 under the action of water pressure, and the sealing surface seals against the guide surface 201, thereby closing the second water inlet 802, and the inlet water flows out from the first water outlet channel.

[0050] When water supply is stopped, Fig.10 As shown, the guide rod device moves upward under the elastic force of the elastic part 70, opening the second water inlet 802, so that the dirt remaining on the surface of the filter 20 slides downward along the guide surface 201 and finally flows out of the bubbler from the second water outlet channel; it is also possible to push the guide rod device upward in the water-inlet state, thereby opening the second water inlet 802 and discharging the dirt, and at this time water flows out of the first water outlet channel and the second water outlet channel at the same time.

[0051] The utility model also provides a water outlet device 120, such as Figure 11-12 As shown, it includes a water outlet valve body 1201, and the water outlet of the water outlet valve body 1201 is provided with a descaling bubbler 10 as described above. Specifically, the housing 40 is threadedly matched with the water outlet, so that the bubbler 10 is hidden and installed in the water outlet device 120, and the overall appearance is fashionable and beautiful.
