Description

Technical Field

[0001] The present invention relates to the technical field related to water purifiers, and in particular to a bubbler. Background Art

[0002] In water purifiers and equipment with self-cleaning function, micro-nano bubble water is mostly produced or used for self-cleaning. Micro-nano bubbles can be produced by ultrasonic cavitation, chemical generation, electrolysis, dissolved gas release, and dispersed air.

[0003] At present, a bubbler is usually set up to force air to dissolve in water under pressure to form a supersaturated state, and then the gas is released again under pressure to produce a large number of microbubbles, thereby producing micro-nano bubble water;

[0004] However, most existing bubblers only release bubbles through a single expansion hole, and the bubble release effect is relatively poor. Summary of the invention

[0005] Based on this, it is necessary to provide a bubbler with relatively good micro-nano bubble release effect to address the problem of poor bubble release effect of current bubblers.

[0006] The present application provides a bubbler, comprising a main body, wherein a water flow channel is formed through the main body, and at least one group of bubbler components is arranged in the water flow channel, each of the bubbler components comprises a baffle and a filter respectively fixedly connected to the inner wall of the water flow channel; a plurality of flow channels are also formed between the baffle and the main body, the flow channels connect the water flow channels on both sides of the baffle, and the outlet direction of the flow channel is parallel to the cross-section of the water flow channel.

[0007] By designing the outlet direction of the flow channel to be parallel to the cross-section of the water flow channel, the water will rush out along the outlet direction of the flow channel (that is, the direction parallel to the cross-section of the water flow channel) after passing through the flow channel. Therefore, there will be impact between the water flows rushing out from different outlets and between the water flow and the inner wall of the water flow channel, thereby achieving further cutting of the dissolved gas, and the water flow after the impact will be buffered, mixed and release pressure in the space between the baffle and the filter, thereby effectively improving the bubble release effect.

[0008] In one of the embodiments, the plurality of flow channels are evenly arranged along the circumference of the water flow channel, and an outlet of each flow channel is oriented toward the central axis of the water flow channel along the radial direction of the water flow channel.

[0009] With this arrangement, on the one hand, the water outlets from different flow channel outlets can cut the dissolved gas through mutual self-impact; on the other hand, the impact position is located near the central axis of the water flow channel, and there is sufficient space so that the water flow after the impact can be fully buffered, mixed, and release pressure to increase the bubble release effect.

[0010] In one embodiment, the inlet and outlet areas of the flow channel are both 7.85×10 -3 mm 2 ~7.07×10 - 2 mm 2 .

[0011] With this arrangement, the aperture of each flow channel is smaller than that of a traditional expansion hole, which will not affect the bubble release effect. The multiple flow channels effectively increase the total water flow rate and the output of bubble water.

[0012] In one embodiment, six flow channels are opened between each of the baffles and the main body.

[0013] Such an arrangement can increase the outflow rate of the bubble water as much as possible while ensuring the bubble release effect.

[0014] In one embodiment, the flow channel is opened on the side wall of the water flow channel.

[0015] Compared with opening the flow channel at the baffle, part of the water flow may not impact the baffle and directly enter the flow channel, which can effectively increase the cutting effect of the bubbles in the water flow and increase the bubble release effect.

[0016] In one of the embodiments, two groups of the bubbling components are sequentially arranged in the water flow channel along the water flow direction.

[0017] Such an arrangement makes the bubble release effect, cost, volume and other parameters of the bubbler relatively excellent.

[0018] In one embodiment, the flow channel includes an increasing section, and the cross-sectional area of ​​the increasing section increases along the water flow direction.

[0019] This arrangement allows the water flow to gradually form a negative pressure as the cross-sectional area of ​​the increasing section slowly increases after entering the increasing section, thereby gradually releasing the pressure on the water flow and facilitating the release of dissolved bubbles in the water flow.

[0020] In one embodiment, the flow channel is divided into the increasing section and the decreasing section along the water flow direction, and the cross-sectional area of ​​the decreasing section decreases along the water flow direction.

[0021] Such an arrangement allows the water flow to undergo two pressurization and pressure release processes when passing through the flow channel, and the dissolved gas is fully released through the secondary pressurization and pressure release, so as to facilitate subsequent water flow impact cutting to form bubbles.

[0022] In one embodiment, the flow channel is in the shape of a water drop, and the tip of the water drop is the inlet of the flow channel.

[0023] Such an arrangement can increase the cross-sectional variation of the increasing section and the decreasing section while ensuring that the flow channel is streamlined as a whole and that the flow channel thickness is small, thereby increasing the bubble release effect.

[0024] In one embodiment, the inner wall of the flow channel close to the central axis of the water flow channel is flush with the inner wall of the water flow channel, and has a protrusion that imitates the inner wall of the flow channel away from the central axis of the water flow channel, so that the flow channel is arranged in an arc shape.

[0025] With such arrangement, the protrusion and the inner wall of the flow channel on the side away from the central axis of the water flow channel can both guide the water flow, thereby further increasing the smoothness of the water flow when passing through the flow channel and increasing the pressure relief effect.

[0026] The above-mentioned bubbler firstly impacts and collides with the baffle plate after the high-speed water flow in the supersaturated state pressurized by the front equipment, and the impact force can cut the gas dissolved in the high-speed fluid, thereby increasing the bubble release effect; secondly, since the flow channel aperture is relatively small compared to the water flow channel, when the water flow enters and leaves the flow channel, it has the effect of first pressurizing and then releasing the pressure, so as to release the gas dissolved in the water flow; thirdly, after the water flow passes through the flow channel, it will rush out in the direction of the flow channel outlet, and the water flows rushing out from different outlets and between the water flow and the inner wall of the water flow channel will impact, thereby further cutting the dissolved gas, and the water flow after the impact will buffer, mix and release the pressure in the space between the baffle plate and the filter screen, thereby effectively improving the bubble release effect; finally, the water flows through the filter screen to achieve further cutting, thereby further increasing the bubble release effect.

[0038] Please combine Figure 1 as well as Figure 2 As shown, the present application provides a bubbler, including a main body 100, the main body 100 is provided with a water flow channel 10, at least one group of bubbler components 20 is arranged in the water flow channel 10, each bubbler component 20 includes a baffle 21 and a filter 22 respectively fixedly connected to the inner wall of the water flow channel 10; a plurality of flow channels 30 are also provided between the baffle 21 and the main body 100, the flow channels 30 connect the water flow channels 10 on both sides of the baffle 21, and the outlet direction of the flow channel 30 is parallel to the cross-section of the water flow channel 10.

[0039] For ease of description, the water flow in this application refers to a water vapor mixture.

[0040] In the present application, the outlet direction of the flow channel 30 is designed to be parallel to the cross-section of the water flow channel 10, so that after the water flows through the flow channel 30, it will rush out along the outlet direction of the flow channel 30 (that is, the direction parallel to the cross-section of the water flow channel 10). Therefore, there will be impacts between the water flows rushing out from different outlets and between the water flows and the inner wall of the water flow channel 10, thereby achieving further cutting of the dissolved gas, and the water flow after the impact will be buffered, mixed and release pressure in the space between the baffle 21 and the filter screen 22, thereby effectively improving the bubble release effect.

[0041] In some embodiments, the filter screen 22 of the same set of bubbler components 20 is arranged behind the baffle 21 along the water flow direction. At this time, the principle of the bubbler component 20 cutting the water flow to release bubbles is as follows:

[0042] First, the high-speed water flow in a supersaturated state after being pressurized by the front equipment collides with the baffle 21. The impact force can cut the gas dissolved in the high-speed fluid and increase the bubble release effect.

[0043] Secondly, since the diameter of the flow channel 30 is relatively smaller than that of the water flow channel 10, when the water flows into and leaves the flow channel 30, it has the effect of first pressurizing and then releasing the pressure, so as to release the gas dissolved in the water flow;

[0044] Thirdly, after the water flows through the flow channel 30, it will rush out along the outlet direction of the flow channel 30. Impact will occur between the water flows rushing out of different outlets and between the water flow and the inner wall of the water flow channel 10, thereby further cutting the dissolved gas. Moreover, the water flow after impact will be buffered, mixed and release pressure in the space between the baffle 21 and the filter screen 22, thereby effectively improving the bubble release effect.

[0045] Finally, water flows through the filter screen 22 to achieve further cutting, further increasing the bubble release effect.

[0046] Of course, the filter screen 22 of the same set of bubbler components 20 can also be arranged in front of the baffle 21 along the water flow direction, and the present application does not make further limitations here.

[0047] It should be noted that the baffle 21 and the filter screen 22 completely block the water flow channel 10 to limit the direction of the water flow, so that the water flow can only flow through the flow channel 30 and the filter screen 22 .

[0048] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, a plurality of flow channels 30 are evenly arranged along the circumference of the water flow channel 10 , and an outlet of each flow channel 30 faces the central axis of the water flow channel 10 along the radial direction of the water flow channel 10 .

[0049] On the one hand, the water outlets of different flow channels 30 can cut dissolved gases through mutual self-impact; on the other hand, the impact position is located near the central axis of the water flow channel 10, and there is sufficient space so that the water flow after the impact can be fully buffered, mixed, and pressure released to increase the bubble release effect.

[0050] Of course, as long as the water flow at the outlet of the flow channel 30 can further impact and cut the dissolved gas, the flow channel 30 can also be arranged in other ways, for example: two flow channels 30 are arranged in pairs as a group, or the outlets of the flow channels 30 are arranged toward the inner wall of the water flow channel 10, etc. In the former, the water flows rushing out of the two corresponding outlets of the flow channels 30 can impact each other, and in the latter, the water flows rushing out of the outlets of the flow channel 30 can impact and collide with the inner wall of the water flow channel 10 to achieve further cutting.

[0051] In some embodiments, the inlet and outlet areas of the flow channel 30 are both 7.85×10 -3 mm 2 ~7.07×10 -2 mm 2 ; Taking the flow channel 30 as an example, when the inlet and outlet are circular, and the diameter of the inlet and outlet is between 0.1 mm and 0.3 mm, the area of ​​the inlet and outlet is 7.85×10 -3 mm 2 ~7.07×10 -2 mm 2If the inlet and outlet of the flow channel 30 are of other shapes, the inlet and outlet areas of the flow channel 30 can be within the above area range.

[0052] Most traditional bubblers rely on only a single expansion hole to achieve bubble release. Experimental verification shows that if the aperture of a single expansion hole is too large, it will affect the bubble release effect, so that the expansion hole has a maximum aperture limit, which in turn limits the water flow rate, resulting in a smaller water flow rate of micro-nano bubble water.

[0053] In the present application, a plurality of small-diameter flow channels 30 are arranged between each baffle 21 and the main body 100. The aperture of each flow channel 30 is smaller than that of the traditional expansion hole, which will not affect the bubble release effect. The plurality of flow channels 30 effectively increase the total water flow rate and increase the output of the bubble water.

[0054] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, six flow channels 30 are opened between each baffle 21 and the main body 100 .

[0055] It is understandable that if the number of flow channels 30 is too large, the difference between the sum of the inlet and outlet diameters of each flow channel 30 around each baffle 21 and the water flow channel 10 will decrease, resulting in the pressurization and pressure release effects of the flow channels 30 being unclear, thereby affecting the bubble release effect; therefore, the present application chooses to open six flow channels 30 between each baffle 21 and the main body 100, which can ensure the bubble release effect while maximizing the water output of the bubble water.

[0056] Please refer to Figure 1 As shown, in some embodiments, the flow channel 30 is opened on the side wall of the water flow channel 10; since the high-speed water flow flows along the axial direction in the water flow channel 10, the flow channel 30 is opened on the side wall of the water flow channel 10 so that the entrance direction of the flow channel 30 is perpendicular to the water flow direction. All water flows entering the flow channel 30 must first impact and collide with the baffle 21. Compared with opening the flow channel 30 on the baffle 21, part of the water flow may not impact the baffle 21 and directly enter the flow channel 30. The above-mentioned embodiments of the present application can effectively increase the cutting effect of the bubbles in the water flow and increase the bubble release effect.

[0057] In some embodiments, the baffle plate 21 may be structurally designed so that when the flow channel 30 is opened in the baffle plate 21 , the inlet of the flow channel 30 is perpendicular to the axial direction of the water flow channel 10 .

[0058] Please refer to Figure 1As shown, in some embodiments, two groups of bubble generating components 20 are sequentially arranged in the water flow direction in the water flow channel 10; by setting a plurality of groups of bubble generating components 20, the above-mentioned bubble releasing process can be repeated to increase the bubble releasing effect; considering factors such as cost and volume, when two groups of bubble generating components 20 are set, the bubble releasing effect, cost, volume and other parameters of the bubbler are all relatively excellent.

[0059] In some embodiments, when multiple groups of bubble components 20 are provided, along the water flow direction, the aperture of the filter 22 inside the bubble component 20 and the inner diameter of the corresponding flow channel 30 are larger than the corresponding sizes of the next group of bubble components 20, so as to gradually increase the effect of bubble release through the multiple groups of bubble components 20.

[0060] Please combine Figure 1 as well as Figure 4 As shown, in some embodiments, the flow channel 30 includes an increasing section, and the cross-sectional area of ​​the increasing section increases along the water flow direction; by designing the increasing section, after the water flow enters the increasing section, as the cross-sectional area of ​​the increasing section slowly increases, a negative pressure is gradually formed, so as to gradually release the pressure of the water flow, which is beneficial to the release of dissolved bubbles in the water flow.

[0061] Please combine Figure 1 as well as Figure 4 As shown, in some embodiments, the flow channel 30 is divided into an increasing section and a decreasing section along the water flow direction, and the cross-sectional area of ​​the decreasing section decreases along the water flow direction.

[0062] After the water flows into the decreasing section, the cross-sectional area of ​​the decreasing section slowly decreases, so as to gradually pressurize the water flow, thereby increasing the pressure relief effect when the water flows out of the flow channel 30 through the decreasing section.

[0063] In addition, by dividing the flow channel 30 into an increasing section and a decreasing section along the water flow direction, two pressurization and pressure release processes occur when the water flows through the flow channel 30. First, there is a pressurization effect when the water flows into the flow channel 30, and a pressure release effect when the water flows along the increasing section. Then, there is a secondary pressurization effect when the water flows along the decreasing section and a pressure release effect when the water flows out of the flow channel 30. The dissolved gas is fully released through the secondary pressurization and pressure release, so as to facilitate the subsequent water flow impact cutting to form bubbles.

[0064] Please combine Figure 1 as well as Figure 4 In some embodiments, the flow channel 30 is in the shape of a water drop, and the tip of the water drop is the inlet of the flow channel 30 .

[0065] The water drop-shaped flow channel 30 makes the flow channel 30 streamlined as a whole, so that water flows more smoothly when passing through the flow channel 30, and the pressure release is more significant during the pressure release process.

[0066] In addition, the water drop-shaped flow channel 30 is relatively flat, and the wall thickness requirement of the main body 100 is relatively low, so that the main body 100 can be designed to be relatively thin. On the one hand, since the bubbler needs to be installed in the corresponding waterway, the high-speed water flow will collide with the end face of the main body 100 when entering the water flow channel 10, resulting in a loss of water flow velocity. Reducing the wall thickness of the main body 100 can reduce the loss of water flow velocity due to collision loss. On the other hand, it is also conducive to the miniaturization of the bubbler and its applicable equipment.

[0067] Therefore, the teardrop-shaped flow channel 30 can increase the cross-sectional variation of the increasing section and the decreasing section while ensuring that the flow channel 30 is streamlined as a whole and that the thickness of the flow channel 30 is small, thereby increasing the bubble release effect.

[0068] Please combine Figure 1 and Figure 4 As shown, in some embodiments, the inner wall of the flow channel 30 close to the central axis of the water flow channel 10 is flush with the inner wall of the water flow channel 10, and has a protrusion 31 that imitates the inner wall of the flow channel 30 away from the central axis of the water flow channel 10, so that the flow channel 30 is arranged in an arc shape.

[0069] By providing a protrusion 31 that is contoured to the inner wall of the flow channel 30 so that the flow channel 30 is arranged in an arc shape, the protrusion 31 and the inner wall of the flow channel 30 on the side away from the central axis of the water flow channel 10 can both guide the water flow, thereby further increasing the smoothness of the water flow when passing through the flow channel 30 and increasing the pressure relief effect.

[0070] Of course, the flow channel 30 may also be other structures, as long as the flow channel 30 is arc-shaped as a whole and can smoothly guide the water flow, the present application does not make any further limitations here.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
