Description

Technical Field

[0001] The utility model relates to the technical field of bubble generation, in particular to a bubbler and a gas water heater. Background Art

[0002] When water contains a large number of bubbles, the water can carry the bubbles to contact the surface to be cleaned, causing some bubbles to break near the surface to be cleaned and generate a certain impact force, thereby enabling the surface to be cleaned more efficiently.

[0003] Among them, the smaller the diameter of the bubbles contained in the water, the longer the bubbles can stay in the water, the larger the number of bubbles that can remain unbroken before reaching the cleaning surface, and the greater the energy generated when a single bubble breaks, so that the water containing bubbles has a higher cleaning efficiency for the surface to be cleaned.

[0004] However, the bubbler in the related art usually includes a pump and a mixing tank, which specifically pumps air into the water through the pump, and fully mixes the water and the air in the mixing tank to generate bubbles in the water. However, this technology requires the use of a pump and a mixing tank, which has high manufacturing and use costs, occupies a large space, and in order to avoid excessive air pressure in the mixing tank that makes it difficult for water to enter the mixing tank normally, it requires a high input water pressure, and it is difficult for users to conveniently obtain bubble water with tiny bubbles. Utility Model Content

[0005] One of the technical problems solved by the utility model is to provide a bubbler, which can effectively solve the problem of low convenience in use of the bubbler.

[0006] The second technical problem solved by the utility model is to provide a gas water heater, which can effectively solve the problem of low cleaning efficiency of the water output by the gas water heater on the surface to be cleaned.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0008] A bubbler, comprising:

[0009] A foaming body, wherein the foaming body has a foaming water inlet end and a foaming water outlet end opposite to each other, and the foaming body is further provided with a Venturi channel, wherein the Venturi channel comprises a gradually contracting section and a gradually expanding section which are sequentially connected along a direction from the foaming water inlet end to the foaming water outlet end; and,

[0010] A breaking piece, wherein the breaking piece is arranged on the bubble generating body and is located on a side of the gradually expanding section away from the bubble generating water inlet end, the breaking piece comprises a first cylinder, a plurality of blades and a cross beam, one end of the blade is fixedly connected to the inner wall of the first cylinder, the blades are spaced around the central axis of the first cylinder, the plurality of blades divide the inner cavity of the first cylinder into a plurality of flow channels, and the two ends of the cross beam are respectively connected to two adjacent blades.

[0011] Compared with the background technology, the bubbler of the utility model has the following beneficial effects:

When the water enters the gradually expanding section from the tapering section, since the aperture of the gradually expanding section gradually increases from the bubbler water inlet end to the bubbler water outlet end, the flow velocity of the water gradually slows down and the pressure gradually increases. At this time, the released air can be squeezed by water to shear and break the bubbles into bubbles with smaller diameters.

[0013] Furthermore, a breaking piece is provided so that the bubble water flowing out from the gradually expanding section can enter the circulation channel, and when the water carrying bubbles hits the cross beam, the bubbles in the water can be further broken by the cross beam, so that the diameter of the bubbles in the water can be further reduced.

[0014] In addition, since the bubbler provided by the utility model reduces the pressure of the water flow through a tapered section, the air originally dissolved in the water is released to form bubbles, that is, the bubbles are not pressed into the water by a pump. Therefore, the bubbler provided by the utility model does not require the use of a pump and a mixing tank, and also has lower requirements for the water pressure input to the bubbler.

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0051] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0052] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] like Figures 1 to 3 As shown, the present embodiment provides a bubbler 100, which can be applied to water outlet devices including but not limited to gas water heaters, faucets, showers, dishwashers, etc., to improve the cleaning efficiency of the water output by the water outlet device on the surface to be cleaned. Specifically, the bubbler 100 includes a bubbler body 1 and a breaking member 2. The bubbler body 1 has a bubbler water inlet end 111 and a bubbler water outlet end 112 relative to each other. The bubbler body 1 is also provided with a venturi channel 120. The venturi channel 120 includes a tapered section 1201 and a gradually expanding section 1203 which are sequentially connected along the direction from the bubbler water inlet end 111 to the bubbler water outlet end 112. Along the direction from the bubbler water inlet end 111 to the bubbler water outlet end 112, the aperture of the tapered section 1201 gradually decreases, and the gradually expanding section 1203 gradually increases. The aperture of 203 gradually increases, the breaking piece 2 is connected to the foaming body 1 and is located on the side of the expanding section 1203 away from the foaming water inlet end 111, the breaking piece 2 includes a first cylinder 21, a plurality of blades 22 and a crossbeam 23, one end of the blade 22 is fixedly connected to the inner wall of the first cylinder 21, the blades 22 are spaced around the central axis of the first cylinder 21, the plurality of blades 22 divide the inner cavity of the first cylinder 21 into a plurality of flow channels 24, and the two ends of the crossbeam 23 are respectively connected to two adjacent blades 22.

[0054] By providing the bubbling body 1 with a Venturi channel 120, the flow rate of the water flow can be accelerated through the tapered section 1201 whose aperture gradually decreases from the bubbling water inlet end 111 to the bubbling water outlet end 112, and the pressure of the water flow can be reduced, so that the air originally dissolved in the water will be released to form bubbles. When the water enters the gradually expanding section 1203 from the tapered section 1201, since the aperture of the gradually expanding section 1203 gradually increases from the bubbling water inlet end 111 to the bubbling water outlet end 112, the flow rate of the water gradually slows down and the pressure gradually increases. At this time, the released air can be squeezed by the water to shear and break the bubbles into bubbles with smaller diameters.

[0055] Furthermore, by providing a breaking piece 2, the bubble water flowing out from the gradually expanding section 1203 can enter the circulation channel 24, and when the water carrying bubbles collides with the cross beam 23, the bubbles in the water can be further broken by the cross beam 23, so that the diameter of the bubbles in the water can be further reduced.

[0056] By providing a crossbeam 23 connected between two adjacent blades 22, the structural strength of the blades 22 can be improved, so that the structural shape of the blades 22 can be easily maintained in a relatively stable state, so that the breaking effect of the breaking element 2 on the bubbles in the water can be easily maintained stable.

[0057] In addition, since the bubbler 100 provided by the utility model reduces the pressure of the water flow through the tapered section 1201, the air originally dissolved in the water is released to form bubbles, that is, the bubbles are not pressed into the water by a pump. Therefore, the bubbler 100 provided by the utility model does not require the use of a pump and a mixing tank, and also has lower requirements for the water pressure input to the bubbler 100. Therefore, it is more convenient to use.

[0058] In one embodiment, the venturi channel 120 also includes a throat 1202 connected between the tapered section 1201 and the divergent section 1203. The throat 1202 is a structure with a constant aperture so that the water flow can maintain a low pressure state in the throat 1202 for a period of time, thereby allowing the air originally dissolved in the water to be more completely released over a longer period of time.

[0059] In one embodiment, all the circulation channels 24 are provided with crossbeams 23 , so that water entering any circulation channel 24 can collide with the crossbeams 23 , so that the bubbles carried by the water can be further cut and broken.

[0060] Please combine Figure 4 and Figure 5 As shown, in one embodiment, a plurality of beams 23 are provided in at least one circulation channel 24, and the plurality of beams 23 are arranged at intervals along the radial direction of the first cylinder 21, so that by increasing the number of beams 23, the distribution positions of the beams 23 can be made wider, so that the possibility that the bubbles carried by the water can collide with the beams 23 is higher, and more bubbles can be further cut and broken, so as to effectively increase the number of small-diameter bubbles carried by the water.

[0061] In other embodiments, all the circulation channels 24 may be provided with cross beams 23, and at least one circulation channel 24 may be provided with a plurality of cross beams 23, so that the breaking element 2 can break the bubbles in the water more efficiently.

[0062] In one embodiment, the cross beam 23 is disposed at one end of the circulation channel 24 close to the bubble inlet end 111, so that when the water enters the circulation channel 24, the bubbles carried in the water can be broken by the cross beam 23, and then the broken bubbles and water enter the circulation channel 24 to be further evenly mixed in the circulation channel 24, so that the distribution uniformity of the bubbles in the water flowing out of the breaking member 2 can be better.

[0063] In other embodiments, the cross beam 23 may also be disposed at an end of the circulation channel 24 away from the bubble water inlet end 111 , or may be disposed at a middle position of the circulation channel 24 .

[0064] Please combine Figure 6 As shown, in one embodiment, the bubbler 100 includes a plurality of breaking pieces 2, and the plurality of breaking pieces 2 are arranged in sequence along the direction from the bubble water inlet end 111 to the bubble water outlet end 112 to form a breaking assembly. Among two adjacent breaking pieces 2, any one flow channel 24 of one breaking piece 2 is connected with at least one flow channel 24 of the other breaking piece 2. By increasing the number of breaking pieces 2, the number of times that water collides with the cross beam 23 can be further increased, so as to further increase the number of small-diameter bubbles carried by the water and further reduce the diameter of the bubbles carried by the water.

[0065] In one embodiment, the circulation channel 24 has a first opening 241 and a second opening 242 which are opposite to each other in the extension direction of the central axis of the first cylinder 21. For any two adjacent crushing members 2, in the extension direction of the central axis of the first cylinder 21, the contour of the first opening 241 of one of the two crushing members 2 overlaps with the projection of the contour of the second opening 242 of the other on a plane perpendicular to the central axis. Therefore, the first opening 241 of one crushing member 2 is connected to the second opening 242 of the other crushing member 2 and is partially staggered. Therefore, when water flows out of the second opening 242 of one crushing member 2 to enter the first opening 241 of the other crushing member 2, the water flow can also collide with the end of the blade 22 located at the first opening 241. Therefore, the end of the blade 22 can also be used to further cut the bubbles carried by the water, so as to further improve the cutting efficiency of the crushing member 2 on the bubbles and reduce the diameter of the bubbles carried by the water.

[0066] It can be understood that, at this time, among two adjacent crushing members 2 , any one flow channel 24 of one crushing member 2 is simultaneously connected to two flow channels 24 of the other crushing member 2 .

[0067] In one embodiment, a limiting protrusion 211 is further provided at one end of the first cylinder 21, and a limiting groove 212 is further provided at the other end of the first cylinder 21. For any two adjacent crushing members 2, the limiting protrusion 211 of one of the two is plugged into the limiting groove 212 of the other of the two, so that the relative posture of the two adjacent crushing members 2 can be limited by the matching plugging of the limiting protrusion 211 and the limiting groove 212, so that the posture stability of the crushing members 2 during use is better, and then the cutting effect of the crushing members 2 on the bubbles carried in the water is better.

[0068] In other embodiments, for any two adjacent crushing pieces 2, the first opening 241 of one crushing piece 2 can be connected with the second opening 242 of the other crushing piece 2 and partially staggered, and the limiting protrusion 211 of the crushing piece 2 away from the gradually expanding section 1203 can be cooperated and inserted into the limiting groove 212 of the crushing piece 2 close to the gradually expanding section 1203, so that the limiting protrusion 211 can be cooperated and inserted with the limiting groove 212, so that the two adjacent crushing pieces 2 can be maintained in a posture where the first opening 241 of one crushing piece 2 is connected with the second opening 242 of the other crushing piece 2 and partially staggered, so that the crushing piece 2 can be maintained in a state where the end of the blade 22 can be used to further cut the bubbles carried by the water.

[0069] In one embodiment, at least one blade 22 is connected to the inner wall of the first cylinder 21 at one end and is inclined with respect to the central axis of the first cylinder 21, and all the blades 22 have the same inclination direction, so that water can form a vortex along the inclined portion of the blade 22 in the flow channel 24, and then obtain greater kinetic energy under the action of centrifugal force, so as to compensate for the kinetic energy loss generated when the water impacts the beam 23 and the blade 22 to a certain extent, thereby preventing the water from slowing down too quickly when flowing through the crushing element 2.

[0070] When the bubbler 100 includes a plurality of breakers 2 as described in the aforementioned technical solution, the blades 22 of all the breakers 2 have the same inclination direction, so that when water flows in the flow channels 24 of different breakers 2, vortices rotating in the same manner are formed without turning the vortex direction, thereby avoiding additional kinetic energy loss.

[0071] like Figure 4 , Figure 6 and Figure 7 As shown, in one embodiment, for a crushing member 2, in the extension direction along the central axis of the first cylinder 21, the projection part of the contour of the first opening 241 and the contour of the second opening 242 on the plane perpendicular to the central axis can be overlapped, so that when each crushing member 2 is arranged with the second opening 242 aligned, it can naturally form a structure in which the first opening 241 of one crushing member 2 is connected and staggered with the second opening 242 of the other crushing member 2 in any two adjacent crushing members 2. In other words, the crushing members 2 can be made to have the same shape structure and the same posture, so that the first opening 241 of one crushing member 2 is connected and staggered with the second opening 242 of the other crushing member 2 in any two adjacent crushing members 2, so that the efficiency of crushing bubbles in water by using multiple crushing members 2 is higher, wherein, for the convenience of observation, Figure 7 The crossbeam 23 is omitted, and the outline position of a second opening 242 is shown by a thick dotted line.

[0072] In other embodiments, the blades 22 may also be parallel to the central axis of the first cylinder 21 , so that water flows in the flow channel 24 along a direction parallel to the central axis of the first cylinder 21 .

[0073] In one embodiment, the ends of two adjacent blades 22 away from the inner wall of the first cylinder 21 can be connected by a crossbeam 23, so that the ends of the two adjacent blades 22 away from the inner wall of the first cylinder 21 can support each other, so that the structural stability of the two adjacent blades 22 during use is better.

[0074] like Figure 5 As shown, in another embodiment, two adjacent blades 22 extend toward the central axis of the first cylinder 21 at one end away from the inner wall of the first cylinder 21 and are spaced apart, so that the water in the circulation channel 24 can also enter other circulation channels 24 through the intervals between the multiple blades 22, and in this process, the water can also collide with the end of the blade 22 away from the inner wall of the first cylinder 21, so that the bubbles carried by the water can be further cut and broken by the end of the blade 22 away from the inner wall of the first cylinder 21, thereby further improving the cutting and breaking efficiency of the breaking member 2 on the bubbles carried by the water.

[0075] In other embodiments, among the multiple blades 22, at least one pair of adjacent two blades 22 may be connected by a cross beam 23 at one end away from the inner wall of the first cylinder 21, and at least one pair of adjacent two blades 22 may extend toward the central axis of the first cylinder 21 at one end away from the inner wall of the first cylinder 21 and be spaced apart.

[0076] Please combine Figure 3 and Figure 8 As shown, in one embodiment, the foaming body 1 is provided with a plurality of venturi channels 120 distributed at intervals, wherein at least part of the venturi channels 120 are arranged around the central axis of the first cylinder 21, so that by increasing the number of the venturi channels 120, the water flow path in the foaming body 1 is increased, so that the bubbler 100 can be used to perform bubble treatment on water with a larger flow rate, such as Figure 8 As shown, Figure 8 It is exemplarily shown that the foaming body 1 is provided with seven Venturi channels 120, wherein one Venturi channel 120 is provided in the middle part of the foaming body 1 (that is, approximately coaxially with the central axis of the first cylinder 21), and the remaining six Venturi channels 120 are arranged around the one Venturi channel 120 at intervals.

[0077] like Figure 2 , Figure 8 and Figure 6As shown, in one embodiment, the foaming body 1 also includes an integrally formed second cylinder 11 and a foaming portion 12, the second cylinder 11 having a foaming water inlet end 111 and a foaming water outlet end 112, the foaming portion 12 is arranged on a side of the second cylinder 11 close to the foaming water inlet end 111, the foaming portion 12 is provided with a Venturi channel 120, the second cylinder 11 has a accommodating cavity 113 located on the side of the foaming portion 12 away from the foaming water inlet end 111, the Venturi channel 120 is communicated with the accommodating cavity 113, the breaking component 2 is arranged in the accommodating cavity 113, so that the position of the breaking component 2 can be limited by the foaming body 1. On the one hand, the relative position accuracy of the flow channel 24 of the breaking component 2 and the Venturi channel 120 of the foaming body 1 can be made easier to meet the design requirements, and on the other hand, there is no need to additionally set a structure for fixing the foaming body 1 and the breaking component 2, which can make the structure of the bubbler 100 simpler.

[0078] In one embodiment, a spacing cavity 114 is formed between one end surface of a crushing member 2 close to the bottom wall of the accommodating cavity 113 and the bottom wall of the accommodating cavity 113, so that water flowing out of the gradually expanding section 1203 will first enter the spacing cavity 114 and then enter the flow channel 24. The flow path of the water can be further adjusted through the spacing cavity 114, so that the water can more fully hit the crossbeam 23. It should be noted that in Figure 3 In the figure, since the opening of the accommodating cavity 113 is located below the vertical direction in the figure, the bottom wall of the accommodating cavity 113 is located above the vertical direction in the figure, that is, Figure 3 In the figure, the wall located at the top of the accommodating cavity 113 is actually the bottom wall of the accommodating cavity 113.

[0079] It can be understood that when a plurality of crushing members 2 form a crushing assembly as described in the above technical solution, a spacing cavity 114 is formed between an end surface of the crushing assembly close to the bottom wall of the accommodating cavity 113 and the bottom wall of the accommodating cavity 113 .

[0080] In one embodiment, a plurality of first protrusions 115 are provided on the bottom wall of the accommodating cavity 113, and one end face of the crushing member 2 abuts against the first protrusion 115, so that the crushing member 2 can be limited in the accommodating cavity 113 by the first protrusion 115 to prevent the crushing member 2 from entering the partition cavity 114, thereby preventing the crushing member 2 from affecting the adjustment effect of the partition cavity 114 on the flow path of water.

[0081] In one embodiment, the bubbler body 1 is an integrally formed injection molded part, which can reduce the manufacturing difficulty of the bubbler body 1 on the one hand, and reduce the number of parts included in the bubbler 100 on the other hand, thereby reducing the assembly steps of the bubbler 100 and further reducing the production cost of the bubbler 100.

[0082] The bubbler 100 usually needs to be connected to an external water supply pipe and an external water outlet, wherein the bubbler water inlet end 111 of the bubbler 100 can be sealed and connected to the external water supply pipe, and the venturi channel 120 is connected to the inside of the external water supply pipe.

[0083] Furthermore, in one embodiment, the bubbler outlet end 112 of the bubbler 100 can be sealed and connected to the external water outlet head, and the flow channel 24 of the breaking member 2 is connected to the inside of the external water outlet head.

[0084] Please see again Figures 1 to 3 In another embodiment, the bubbler 100 further includes a water outlet adapter 3, the water outlet adapter 3 has a relative joint water inlet 31 and a joint water outlet 32, and the water outlet adapter 3 has a first adapter channel 33 that passes through the joint water inlet 31 and the joint water outlet 32, the joint water inlet 31 is detachably sealed and sleeved on the outer periphery of the bubble water outlet end 112, the first adapter channel 33 is connected to the circulation channel 24, and the joint water outlet 32 ​​is used for detachably sealingly connecting to the external water outlet head, so that the bubble water outlet end 112 can be indirectly connected to the external water outlet head through the water outlet adapter 3, and by providing the water outlet adapter 3, there is no need to change the specific structure of the bubble water outlet end 112 of the bubbler body 1 according to the structure of the external water outlet head. In other words, the bubbler body 1 can be connected to different external water outlet heads by replacing the water outlet adapter 3 that is adapted to the external water outlet head.

[0085] In one embodiment, a second protrusion 34 is provided in the first adapter channel 33, and the second protrusion 34 is fixedly connected to the inner wall of the water outlet adapter 3. The top end of the second protrusion 34 extends toward the joint water inlet 31, and the top end of the second protrusion 34 abuts against the side of a breaking component 2 away from the bubbler water inlet end 111, so that the relative position of the breaking component 2 and the bubbler body 1 can be limited by the second protrusion 34, avoiding the breaking component 2 from being separated from the bubbler body 1, thereby keeping the bubbler 100 stable.

[0086] In other embodiments, the breaking piece 2 may also be directly connected to the foaming body 1 by a detachable connection method such as snap connection or screw connection, so that the relative position of the breaking piece 2 and the foaming body 1 can remain stable during use.
