Through the quantity more than or equal to 4 that make the through-hole, can ensure that the bubble can the capacity get into stock solution container, stir the liquid in the stock solution container, guarantee bubble generating device's dechlorination effect. And through making the quantity of through-hole be less than or equal to 36, can effectively avoid on the one hand the through-hole quantity too much and influence the dechlorination effect, on the other hand can effectively avoid the opening area undersize of every through-hole and increase liquid heating device's operating noise. Further, by making the opening area of each through-hole 33mm or more²And is less than or equal to 50mm². The running noise of the liquid heating device can be reduced while ensuring that the bubbles can be moved out in a large quantity.

In one possible design, the difference between the width of the cavity and the width of the heating device is greater than or equal to-5 mm and less than or equal to 20mm, wherein the width of the cavity is the distance between the shroud and the skirt.

In the design, a heating device is arranged below the cavity, so that the enclosed cavity is a concentrated heating area, namely a quick boiling area, wherein the width of the cavity is the distance between the enclosing plate and the skirt edge. The width of the cavity can be close to the width of the heating device, can also be larger than the width of the heating device, and certainly can also be smaller than the width of the heating device, but the width of the cavity is not easy to be different from the width of the heating device too much, otherwise, the effect of centralized heating can not be realized, and heat waste can also be caused. Therefore, the difference value between the width of the cavity and the width of the heating device is larger than or equal to-5 mm and smaller than or equal to 20mm, and the cavity can be guaranteed to have a better concentrated heating effect.

For example, when the bubble generating device 130 is repaired or replaced, the bubble generating device 130 may be rotated out of the interior of the liquid storage container 110 in a reverse direction, and when the bubble generating device 130 is installed, the bubble generating device 130 may be placed in the liquid storage container 110 to rotate in a forward direction and be firmly connected to the liquid storage container 110.

Of course, in other embodiments, the bubble generating device 130 may be detachably connected to the reservoir 110. For example, the air bubble generating device 130 is connected to the liquid storage container 110 by the magnetic attraction of the magnetic member, or connected by a snap-fit manner, etc., but not limited to a screw-on connection.

In a particular application, another manner of twist-on attachment of the bubble generating device 130 to the reservoir 110 is defined. At least two sections of ribs 111 are arranged on the inner wall of the liquid storage container 110, and at least two sections of grooves are arranged on the outer wall of the bubble generating device 130. Specifically, in the process of installing the bubble generating device 130 in the liquid storage container 110, the bubble generating device 130 can be placed from top to bottom with the groove aligned with the position of the rib 111, so that at least two sections of grooves of the bubble generating device 130 completely accommodate at least two sections of ribs 111 on the inner wall of the liquid storage container 110; and then the bubble generating device 130 is rotated, so that at least two sections of the ribs 111 on the inner wall of the liquid storage container 110 can move out of at least two sections of the grooves, and the ribs 111 can abut against the non-groove parts of the bubble generating device 130 after moving out of the grooves, thereby realizing the stable connection between the bubble generating device 130 and the liquid storage container 110 and realizing the gradual transition of the bubble generating device 130 from the non-screwing state to the screwing state. When the bubble generating device 130 needs to be taken out, the rotating direction can be opposite to the rotating direction, so that the convex rib 111 enters the groove again, and the bubble generating device 130 can be taken out from the upper part.

Moreover, the assembly and disassembly of the bubble generating device 130 are realized by adopting the mode that the segmented convex ribs 111 are matched with the grooves, on the premise that the screwing connection strength of the bubble generating device 130 and the liquid storage container 110 is met, the change of the cavity wall of the liquid storage container 110 is small, the change of the structure of the bubble generating device 130 is small, the process flow is favorably reduced, the process strength is ensured, the product cost is saved, and the market competitiveness of the product is improved.

Further, the groove extends to the lower edge of the bubble generating device 130, so that the groove can directly accommodate the rib 111 when the bubble generating device 130 is placed in the liquid storage container 110 from top to bottom.

Further, the number of the at least two sections of ribs 111 is equal to that of the at least two sections of grooves, and may be two, three, or four.

Example four:

on the basis of the second embodiment, as shown in fig. 2, 3 and 4, it is further defined that the inner wall of the liquid storage container 110 is provided with at least two sections of ribs 111, and the outer side wall of the bubble generation device 130 is provided with at least two protrusions 131; the at least two protrusions 131 can rotate along with the bubble generating device 130 until being clamped between the at least two sections of ribs 111 and the bottom wall of the liquid storage container 110.

In a particular application, as shown in FIGS. 2, 3 and 4, one manner of twist-on attachment of the bubble generating device 130 to the reservoir 110 is defined. At least two sections of ribs 111 are arranged on the inner wall of the liquid storage container 110, and at least two protrusions 131 which are matched with each other are arranged on the outer side wall of the bubble generation device 130, so that the at least two protrusions 131 of the bubble generation device 130 can be screwed with the at least two sections of ribs 111 on the inner wall of the liquid storage container 110. Specifically, in the process of installing the bubble generating device 130, at least two protrusions 131 on the bubble generating device 130 can be placed on the bottom wall of the liquid storage container 110 from top to bottom in a manner of avoiding the positions of the ribs 111, and then the bubble generating device 130 is rotated to move the at least two protrusions 131 of the bubble generating device 130 to the lower side of the at least two sections of ribs 111 on the inner wall of the liquid storage container 110 until the protrusions 131 are screwed between the at least two sections of ribs 111 on the inner wall of the liquid storage container 110 and the bottom wall of the liquid storage container 110, so that the stable connection between the bubble generating device 130 and the liquid storage container 110 is realized, and the assembly is convenient and rapid. When the bubble generating device 130 needs to be taken out, the bubble generating device 130 can be rotated in the opposite direction to separate the convex part 131 from the convex rib 111.

Moreover, the assembly and disassembly of the bubble generating device 130 are realized by adopting the mode that the segmented convex ribs 111 are matched with the convex parts 131, on the premise that the screwing connection strength of the bubble generating device 130 and the liquid storage container 110 is met, the change of the cavity wall of the liquid storage container 110 is small, the change of the structure of the bubble generating device 130 is small, the process flow is favorably reduced, the process strength is ensured, the product cost is saved, and the market competitiveness of the product is improved.

Further, the number of the at least two sections of ribs 111 and the at least two protrusions 131 is equal, and may be two, three, or four.

It should be noted that the upper side of the present application is the direction in which the opening of the liquid storage container 110 is located relative to the bottom wall of the liquid storage container 110, and the lower side of the present application is the direction in which the bottom wall of the liquid storage container 110 is located relative to the opening of the liquid storage container 110.

Further, at least two sections of ribs 111 are distributed at intervals, and each section of rib 111 extends spirally along the inner wall of the liquid storage container 110.

Specifically, at least two sections of ribs 111 are arranged at intervals along the circumferential direction of the liquid storage container 110, and each section of rib 111 extends spirally along the inner wall of the liquid outlet cavity, so that the head and the tail of each section of rib 111 are not on the same horizontal plane. The convex part 131 is enabled to be gradually close to the convex rib 111 in the height direction of the liquid storage container 110 until the convex part 131 is tightly abutted to the lower end face of the convex rib 111 in the process that the bubble generating device 130 drives the convex part 131 to rotate, so that the at least two convex parts 131 and the at least two sections of convex ribs 111 are gradually changed into the screwing state from the non-screwing state, and the installation stability of the bubble generating device 130 is improved.

Example five:

on the basis of the second embodiment, it is further limited that the inner wall of the liquid storage container 110 is provided with a first thread groove, and the outer side wall of the bubble generating device 130 is provided with a second thread groove, and the first thread groove can be spirally connected with the second thread groove.

Specifically, another manner of twist-on attachment of the bubble-generating device 130 to the reservoir 110 is defined. The inner wall of the liquid storage container 110 is provided with a first thread groove, the outer side wall of the bubble generating device 130 is provided with a second thread groove matched with the first thread groove, and the first thread groove and the second thread groove can be in threaded connection. Specifically, in the process of installing the air bubble generating device 130 in the liquid storage container 110, the air bubble generating device 130 may be placed in the liquid storage container 110, so that the second thread groove abuts against the first thread groove, and then the air bubble generating device 130 is rotated, so that any one thread in the second thread groove is rotated to a position between any two threads in the second thread groove, or any one thread in the first thread groove is rotated to a position between any two threads in the second thread groove, and the air bubble generating device 130 is continuously rotated, so that the first thread groove and the second thread groove are gradually changed into a screwed state from a non-screwed state. When the bubble generating device 130 needs to be taken out, the bubble generating device 130 only needs to be rotated reversely, so that the assembly and disassembly are convenient.

Example six:

in addition to any of the above embodiments, as shown in fig. 1 and 3, the bubble generating device 130 further includes a cavity 140 and at least one through hole 132, and the at least one through hole 132 communicates the cavity 140 and the reservoir 110.

In a particular application, as shown in fig. 1 and 3, the bubble generating means 130 comprises a chamber 140 and at least one through hole 132. The cavity 140 can communicate with the reservoir 110 through the at least one through hole 132, that is, the liquid in the reservoir 110 can enter the cavity 140. Therefore, in the process that the liquid in the liquid storage container 110 is heated by the heating device 120, the liquid in the cavity 140 of the bubble generation device 130 is preferentially heated to generate bubbles due to being closer to the heating device 120, and the bubbles are moved out of the at least one through hole 132 to disturb the liquid in the liquid storage container 110, so as to achieve the chlorine removal effect.

Further, the through hole 132 may be a circular, oval, or other shaped hole. When the number of the through holes 132 is plural, the shapes of the plural through holes 132 may be the same or different.

Example seven:

in addition to the sixth embodiment, as shown in fig. 3, the bubble generating device 130 is further defined to further include a plate body 133, a skirt 134 and a shroud 135. At least one through hole 132 is disposed on the plate body 133; a skirt 134 connected to the outer edge of the plate 133 and extending toward the bottom wall of the reservoir 110; a surrounding plate 135 connected to the plate 133 and extending toward the bottom wall of the liquid storage container 110; the plate 133, shroud 135 and skirt 134 enclose a cavity 140.

In a specific application, as shown in fig. 3, at least one through hole 132 is formed in the plate 133, such that the skirt 134 is connected to the outer edge of the plate 133, and the shroud 135 is connected to the plate 133 and spaced apart from the skirt 134, such that the skirt 134, the shroud 135 and the plate 133 can enclose the cavity 140. Because the cavity 140 has a smaller volume and the heating device 120 is located at or below the bottom wall of the liquid storage container 110, after the bubble generation device 130 is placed on the bottom wall of the liquid storage container 110, the cavity 140 is closer to the heating device 120, and even the heating device 120 can be located right below the cavity 140, so that the cavity 140 can become a concentrated heating area. Therefore, when the heating device 120 works, the generated heat energy can be concentrated in the cavity 140, so that the liquid inside the cavity 140 is heated quickly, even if the temperature of the liquid inside the liquid storage container 110 is integrally low, the liquid inside the cavity 140 can still be heated to boiling preferentially, bubbles are generated inside the cavity 140 and escape from the at least one through hole 132 on the plate body 133, the liquid inside the liquid storage container 110 is disturbed, and the chlorine removal effect is realized. And in the liquid by the heating and temperature rising process, the quantity of bubble constantly increases, and the bubble that escapes from at least one through-hole 132 constantly increases, can constantly disturb liquid in the liquid storage container 110, drives chlorine and flees fast to promote the dechlorination effect.

The chlorine removal is achieved by providing the bubble generating means 130 with a plate body 133, a skirt 134 and a shroud 135, and providing the plate body 133 with at least one through hole 132. Simple structure, convenient processing and cost saving.

As shown in fig. 3, further, the shroud 135 is integrally formed with the plate body 133; or a portion of the plate body 133 is bent to form the shroud 135.

Specifically, the enclosing plate 135 and the plate body 133 may be integrally formed, which not only satisfies the structural strength and the connection strength of the bubble generating device 130, but also has good mechanical properties, and simultaneously avoids unnecessary structural connection. In addition, during the preparation process of the plate body 133, a part of the plate body 133 can be bent to form the enclosing plate 135, and the shape of the enclosing plate 135 can be adjusted according to actual conditions, so as to meet the requirements of different heating containers on the enclosing plate 135.

As shown in fig. 1, it is further defined that at least one of the shroud 135 and skirt 134 is in contact with the bottom wall; or at least one of the shroud 135 and skirt 134, and the bottom wall, is less than or equal to 2 mm.

In a specific application, by making at least one of the surrounding plate 135 and the skirt plate contact with the bottom wall, or making the distance between at least one of the surrounding plate 135 and the skirt 134 and the bottom wall less than or equal to 2mm, it is beneficial to form a relatively closed space in the cavity 140 of the bubble generating device 130, to form a region which can be rapidly boiled by heat, so as to facilitate rapid generation of bubbles under the heating action of the heating device 120, and to discharge the liquid in the disturbed liquid storage container 110 through the at least one through hole 132 for chlorine removal.

In one particular embodiment, the shroud 135 and skirt 134 are both adapted to contact the bottom wall.

In another embodiment, skirt 134 is adapted to contact the bottom wall such that shroud 135 is spaced 1mm or 1.5mm or 2mm from the bottom wall.

Further, the distance between the center of each through hole 132 and the bottom wall of the reservoir 110 is made greater than 0mm, and less than or equal to 20 mm.

In a specific application, the distance H between the center of each through hole 132 and the bottom wall of the reservoir 110 is the height of the bubble generating device 130, i.e., the height of the boiling region. The distance should not be too large, otherwise the water in the cavity needs to be heated for a long time to boil to generate more obvious bubbles, the distance should not be too small, otherwise the chlorine removal effect cannot be exerted, and the generated scale easily blocks the through hole 132. Therefore, through setting up the distance H between the center of every through-hole 132 and the diapire of liquid storage container 110 between 0 to 20mm, H is greater than 0mm, can guarantee that bubble generating device 130 normally plays the dechlorination effect, and through-hole 132 is difficult for being blockked up by the incrustation scale moreover, and this distance is less than 20mm, is favorable to under shorter heating time, and the water boiling of cavity inside produces more bubble.

In a specific embodiment, the distance H between the center of each through hole 132 and the bottom wall of the reservoir 110 is between 2mm and 10 mm.

Further, the distance H between the center of each through hole 132 and the bottom wall of the liquid storage container 110 is between 3mm and 6mm, and the chlorine removal effect is good.

Further, the number of the through holes 132 is made plural, and the opening area of each through hole 132 is inversely related to the number of the through holes 132.

In a particular application, the number and open area of the through holes 132 are defined. The number of the through holes 132 is not too large, otherwise, the through holes do not have a good dechlorination effect, so that the cavity 140 does not have a relatively closed effect, but is greatly communicated with the liquid in the liquid storage container 110, and the liquid in the cavity 140 cannot be boiled preferentially. However, the number of the through holes 132 should not be too small, otherwise, the number of the discharged bubbles is not only influenced, the chlorine removal effect is influenced, but also the abnormal sound of the boiled water is generated during boiling, and even the heat transfer at the bottom is influenced, so that the boiled water jumps early. Moreover, the area of the single through hole 132 should not be too large, which affects the chlorine removal effect too much, and too small not only affects the chlorine removal effect but also affects the heat transfer at the bottom and the water boiling sound. Therefore, by making the opening area of the through holes 132 inversely related to the number of the through holes 132, that is, when the area of the through holes 132 is small, the number of the through holes 132 may be larger, or when the area of the through holes 132 is large, the number of the through holes 132 is smaller, which is beneficial to reducing noise while ensuring the boiling effect.

Further, the number of the through holes 132 is made greater than or equal to 4, and less than or equal to 36; the opening area of each through-hole 132 is 3mm or more²And less than or equal to 50mm²。

In a specific application, the number of the through holes 132 and the size of the opening area of each through hole 132 may affect the chlorine removal effect of the bubble generating means 130 and the operation noise of the liquid heating apparatus 120. Through making the quantity more than or equal to 4 of through-hole 132, can ensure that the bubble can enough get into the stock solution container 110, stir the liquid in the stock solution container 110, guarantee the dechlorination effect of bubble generating device 130. By making the number of the through holes 132 less than or equal to 36, on one hand, the influence of the excessive number of the through holes 132 on the chlorine removal effect can be effectively avoided, and on the other hand, the increase of the operation noise of the liquid heating apparatus 120 due to the excessively small opening area of each through hole 132 can be effectively avoided. Further, by making the opening area of each through-hole 132 33mm or more²And is less than or equal to 50mm². The operating noise of the liquid heating apparatus 120 can be reduced while ensuring that the bubbles can be removed in large quantities.

Specifically, the opening areas of the plurality of through holes 132 may be the same or different. The through holes 132 having the same opening area may have the same shape or different shapes.

In a specific embodiment, the number of through holes 132 is equal to or greater than 8 and equal to or less than 30. The opening area of each through hole 132 is 6mm or more²And is less than or equal to 28mm²。

In another specific embodiment, the number of through holes 132 is greater than or equal to 12 and less than or equal toAt 24. The opening area of each through hole 132 is 9mm or more²And is less than or equal to 16mm²。

Further, the bubble generating device 130 further includes a handle 136 disposed on the plate 133 and extending in a direction away from the bottom wall of the liquid storage container 110.

In specific application, the handle 136 and the bubble generating device 130 can be integrally formed, so that the structural strength and the connection strength of the bubble generating device 130 are ensured, and the bubble generating device has good mechanical properties. The handle 136 may be connected by other means, such as riveting, screwing, welding, or bonding, and the handle 136 may be connected by different means according to different heating vessels.

Specifically, the handle 136 may be provided in a semi-annular configuration for easy grasping by a user, thereby facilitating more convenient detachment and installation of the bubble-generating device 130 by grasping the handle 136. The handle 136 is preferably made of the same material as the bubble generating device 130.

Further, the number of the handles 136 is not easily set to be excessive, the excessive handles 136 cause unnecessary waste of materials, and the excessive handles 136 are not required when the bubble generating device 130 is installed by screwing. The number of the handles 136 may be set to one or two. When the number of the handles 136 is two, the symmetrical arrangement is easy.

Further, the plate 133 is a stainless steel plate, a glass plate, or a ceramic plate.

In a specific application, the plate body 133 of the bubble generating device 130 is made of stainless steel or glass or ceramic material. The stainless steel material has the advantages of resisting weak corrosive media such as air, steam, water and the like, can not be corroded or corroded in the using process, ensures the service life, is safe and can not generate harmful substances to human bodies. The glass has the advantages of stable chemical property, high temperature resistance and the like, the surface of the glass is smooth, the glass is convenient for users to clean, the production cost is low, and the glass is suitable for mass production. The ceramic material has strong heat conductivity, good high-temperature stability, super heat resistance, no erosion of chemical reagents and high stability.

Specifically, the plate 133 may be made of stainless steel, 304 or 316 stainless steel.

Further, the handle 136 is also made of stainless steel.

Example eight:

on the basis of the seventh embodiment, as shown in fig. 1, at least a portion of the cavity 140 is further defined to be located right above the heating device 120.

In this embodiment, by disposing a part or all of the cavity 140 directly above the heating device 120 and in the liquid storage container 110 close to the heating device 120, a fast boiling region of the cavity 140 is advantageously formed, i.e. heat generated by the heating device 120 is rapidly transferred to the cavity 140. Thereby being beneficial to the liquid in the cavity 140 to boil quickly to generate bubbles to stir the liquid in the liquid storage container 110, and realizing the dechlorination effect.

Further, the difference between the width of the cavity 140 and the width of the heating device 120 is greater than or equal to-5 mm and less than or equal to 20mm, wherein the width of the cavity 140 is the distance between the shroud 135 and the skirt 134.

In a specific application, as shown in fig. 1, the heating device 120 is disposed below the cavity 140, so that the enclosed cavity 140 is a concentrated heating area, i.e., a fast boiling area, wherein the width of the cavity 140 is the distance between the shroud 135 and the skirt 134. The width of the cavity 140 may be close to the width of the heating device 120, may also be greater than the width of the heating device 120, and certainly may also be smaller than the width of the heating device 120, but the difference between the width of the cavity 140 and the width of the heating device 120 is not too large, otherwise, the effect of concentrated heating may not be achieved, and heat waste may also be caused. Therefore, by making the difference between the width of the cavity 140 and the width of the heating device 120 greater than or equal to-5 mm and less than or equal to 20mm, a better concentrated heating effect of the cavity 140 can be ensured.

Specifically, as shown in fig. 1, the width of the cavity 140 is L1, and the width of the heating device 120 is L2.

Furthermore, L1-L2 is more than or equal to-5 mm and less than or equal to 20 mm.

In a specific embodiment, the difference between the width L1 of the cavity 140 and the width L2 of the heating device 120 is greater than or equal to 0 and less than or equal to 12 mm.

In a specific application, the heat transfer member 150 is disposed between the heating device 120 and the bubble generating device 130, for transferring heat generated by the heating device 120 to the bubble generating device 130. The heat transfer element 150 facilitates rapid transfer of heat generated by the heating device 120 to the cavity 140 to heat the liquid in the cavity 140, thereby facilitating rapid generation of bubbles by the bubble generation device 130 to disturb the liquid in the liquid storage container 110 for dechlorination.
