The mixer provided in this embodiment is mainly used for mixing liquids. The mixer of the present embodiment can be used for mixing a plurality of liquids. Under the condition that multiple liquids are mixed, the requirement that multiple liquids alternately enter can be met. And under the condition that the liquid supply in a certain path is interrupted, the excessive liquid flow rate of the liquid supply path can be avoided, and the liquid flows into the non-liquid supply pipeline, so that the purpose of backflow prevention is achieved.

In addition, the mixer provided in the present embodiment can also be applied to a filter.

As shown in connection with fig. 1-5, embodiments of the present disclosure provide a mixer including a liquid inlet portion 10 and a mixing portion 20. The liquid inlet part 10 comprises one or more liquid inlet sections 101, and the liquid inlet sections 101 are arranged in parallel; a mixing part 20 communicating with a liquid outlet of the liquid inlet part 10 to mix the liquid flowing in from the plurality of liquid inlet sections 101; the liquid inlet section 101 includes one or more tesla valve units 102, and the tesla valve units 102 are arranged in series, so that liquid flows out from a liquid outlet of the liquid inlet section 101 to the mixing portion 20, and liquid in the mixing portion 20 is prevented from flowing out from a liquid inlet of the liquid inlet section 101.

By adopting the mixer provided by the embodiment of the disclosure, the mixing part 20 with the multipath liquid inlet sections 101 is provided with the tesla valve structure through the liquid inlet sections 101, so that liquid in the mixing part 20 can be prevented from flowing back in the liquid inlet sections 101 when the liquid supply of the liquid inlet sections 101 is interrupted, and liquid in the liquid inlet sections 101 with high liquid flow rate can be prevented from flowing back to the liquid inlet sections 101 with low flow rate under the condition that the liquid flow rates of different liquid inlet sections 101 are different; in addition, the multiple liquid inlet sections 101 can also be used to realize the simultaneous/alternating flow of multiple liquids into the mixing section 20 for mixing.

The mixing part 20 comprises a mixing cavity 201, and a liquid outlet of the liquid inlet section 101 is communicated with the mixing cavity 201. The liquid inlet sections 101 are arranged in parallel, wherein the liquid outlets of the liquid inlet sections 101 can be communicated with the mixing cavity 201 independently or can be communicated with the mixing cavity 201 after being collected into one path.

The feed section 101 comprises one or more tesla valve units 102. Where the same feed section 101 includes a plurality of tesla valve units 102, the plurality of tesla valve units 102 are arranged in series.

A tesla valve is a one-way valve that does not require a moving element. The tesla valve unit 102 comprises a main line and a loop-back branch. When the air flow moves from the first end to the second end, the liquid flowing direction at the junction of the main pipeline and the branch pipeline is consistent with the flowing direction of the liquid at the junction of the main pipeline, the Tesla valve is in a conducting state, when the liquid flows from the second end to the first end, the flowing direction of the liquid at the junction of the branch pipeline and the main pipeline is opposite to the flowing direction of the liquid in the main pipeline, the liquid in the branch pipeline plays a non-return role on the liquid in the main pipeline, and the Tesla valve is in a closing state. The Tesla valve can realize the function of one-way conduction without a movable part. Because, through setting up tesla valve realization liquid unidirectional flow at feed liquor section 101, prevent liquid backward flow, simple structure reduces maintenance cost.

In case the liquid inlet section 101 comprises a plurality of tesla valve units 102, the problem of liquid backflow can be further avoided. The multiple tesla valve units 102 are connected in series and are sequentially connected end to end, i.e. the second end of one tesla valve unit 102 is connected with the first end of an adjacent tesla valve unit 102, so as to ensure the purpose of unidirectional conduction of the liquid inlet section 101.

As shown in connection with fig. 3, the arrows in the figure are the flow directions of the liquid, and the tesla valve unit 102 only allows the liquid to move out in one direction, i.e. from left to right in fig. 3, and the liquid cannot move in the opposite direction.

Illustratively, taking a Tesla valve as an example, in connection with FIG. 4, FIG. 4 illustrates the movement of liquid within the Tesla valve in a conducting direction.

When the liquid passes through the Tesla valve in the forward direction, namely, the liquid flows in from the left side of the Tesla valve and flows out from the right side of the Tesla valve, the liquid is separated at A, one part of the fluid reaches B through a straight line path between A and B, and the other part of the liquid reaches B through an arc path between A and B; the two liquid flows along the straight line path and the circular arc path meet at the point B, the included angle of the flowing direction is an acute angle, and the flowing directions are basically the same, so that the two liquid flows together at the point B to form a stream of liquid, and the liquid smoothly flows out of the right side of the Tesla valve.

Illustratively, taking a Tesla valve as an example, in connection with FIG. 5, FIG. 5 illustrates the movement of liquid within the Tesla valve in the cut-off direction.

When the liquid reversely passes through the tesla valve, namely, the liquid flows in from the right side of the tesla valve, the liquid is separated at the position B, one part of fluid reaches the position A through an arc path between the position B and the position A, the other part of fluid reaches the position A through a straight line between the position B and the position A, two liquids meet at the position A, the gas flowing along the arc path has components towards the right side, the two liquids are similar in mass and almost opposite in flow direction and cancel kinetic energy, and therefore, most of fluid cannot flow out from the left side of the tesla valve, and only a small amount of fluid can flow out from the left side.

A single tesla valve unit 102 cannot realize complete one-way cut-off, but a plurality of tesla valve units 102 are connected in series and then have good one-way cut-off function. Preferably, a plurality of tesla valve units 102 are connected end to end, so that the performance of unidirectional on-off can be further ensured.

The liquid flowing in from the liquid inlet section 101 is mixed in the mixing section 20, and the mixed liquid flows out from the liquid outlet section.

Illustratively, in the first use case, multiple liquids may flow into the mixing chamber 201 of the mixing portion 20 through the multiple liquid inlet sections 101 simultaneously, and after the multiple liquids in the mixing chamber 201 are mixed, the multiple liquids may be discharged from the mixing portion 20 through filtration.

Illustratively, in a second use case, multiple liquids may flow asynchronously through multiple inlet sections 101 into the mixing chamber 201 of the mixing section 20, i.e., there may be a time difference between the multiple liquids flowing into the mixing chamber 201.

Illustratively, in a third use case, the amount of liquid to be mixed is less than or equal to the amount of liquid intake section 101. That is, some of the liquid inlet segments 101 of the plurality of liquid inlet segments 101 are in an un-fed state during use of the mixer.

In the mixer of this embodiment, especially in the second and third use cases, after the liquid enters the mixing cavity 201 through the tesla valve structure of the liquid inlet section 101, the resistance of the liquid outlet section is much smaller than the resistance of the liquid inlet section 101 in the reverse flow direction of the liquid which is not supplied, so that the liquid in the mixing cavity 201 flows to the liquid outlet section under the resistance, and thus the liquid flowing into the mixing cavity 201 can be prevented from flowing back to the liquid inlet section 101 of the liquid inlet section which is not supplied, and the normal use of the mixer and the mixing effect of the liquid are affected. Thus, the multiple inlet sections 101 of the mixer may be selectively partially used, partially without liquid. There is no concern about the problem of backflow in the liquid feed section 101 where liquid is not fed.

Optionally, in the case that the liquid inlet portion 10 includes a plurality of liquid inlet segments 101, the liquid inlet portion 10 further includes: the micro-mixing section 103 is communicated with the liquid outlets of the liquid inlet sections 101; the liquid in the liquid inlet sections 101 flows into the micro-mixing section 103 to be mixed, and flows into the mixing section 20 through the micro-mixing section 103.

Through the micro-mixing section 103, on one hand, the effect of collecting the liquid flowing out of the liquid inlet sections 101 can be achieved, and the situation that the liquid in the liquid inlet sections 101 directly flows into the mixing cavity 201, and the liquid in the mixing cavity 201 splashes due to overlarge flow speed to affect the mixing and filtering effects is avoided; on the other hand, the device can also play a role in primary mixing of various liquids or multiple liquids, so that the liquids can be better mixed with the liquids in the mixing cavity 201, and the uniformity of liquid mixing is improved.

The liquid flow directions of the liquid outlets of the liquid inlet sections 101 are parallel, and the liquid flows into the micro-mixing section 103 along the same direction, so that the liquid of the liquid inlet sections 101 is prevented from being seriously collided when flowing into the micro-mixing section 103, on one hand, the mixing effect is influenced, and on the other hand, the service life of the micro-mixing section 103 is influenced.

Illustratively, a plurality of intake segments 101 are disposed side-by-side in the micromixer segment 103. The number of tesla valve units 102 of the plurality of liquid inlet sections 101 may be the same or different. The specific number can be determined according to the actual situation.

Optionally, the flow area of the micro-mixing section 103 is larger than the flow area of the outlet of the inlet section 101. Thus, the liquid flowing out of the plurality of liquid inlet sections 101 is primarily mixed in the micro-mixing section 103.

Alternatively, the liquid flow directions of the liquid outlets of the liquid inlet sections 101 of the liquid inlet portion 10 are the same.

The liquid flow directions of the liquid outlets of the liquid inlet sections 101 are the same, so that the mutual collision of the liquid when the liquid outlets of the liquid inlet sections 101 flow out can be avoided, liquid resistance is generated, the subsequent liquid is prevented from flowing out of the liquid inlet sections 101, the flow rate of the liquid is reduced, and the mixing efficiency of the mixer is further influenced.

In addition, the liquid flow directions of the liquid outlets of the liquid inlet sections 101 are the same, so that the liquid can be prevented from colliding and splashing to the side wall of the mixing cavity 201 or the side wall of the micro-mixing section 103 when flowing out, and the liquid can hit the side wall of the mixing cavity 201 and the side wall of the micro-mixing section 103 under the condition that the flow speed of the liquid is too fast, so that the structural strength of the mixing part 20 and the micro-mixing section 103 is influenced over time, and the service life is easy to shorten.

Optionally, the number of liquid inlets 10 is one or more.

In the case that the liquid inlet portion 10 is one, the plurality of liquid inlet sections 101 included in the liquid inlet portion 10 can meet the requirement that a plurality of liquids flow into the mixing portion 20 for mixing.

In the case where there are a plurality of liquid inlet portions 10, the plurality of liquid inlet portions 10 can fulfill the need of mixing a plurality of liquids flowing into the mixing portion 20. That is, each liquid inlet portion 10 delivers one liquid into the mixing chamber 201 of the mixing portion 20. In addition, the same liquid inlet portion 10 can also realize the transportation of multiple liquids through a plurality of liquid inlet sections 101 of the liquid inlet portion 10. Thus, the application range of the mixer can be effectively enlarged.

In addition, the plurality of liquid inlet portions 10 can overcome the limitation of the mixer in installation and assembly. Illustratively, in the case where the mixer is mounted to a designated position, the space of the original reserved liquid inlet portion 10 is insufficient, resulting in a reduction in the number of liquid inlet segments 101, thereby affecting the overall use effect of the mixer. At this time, the liquid inlet portion 10 of the original plan is divided into two liquid inlet portions 10, for example, one liquid inlet portion 10 may be arranged according to the original plan, and the other liquid inlet portion 10 may be arranged according to the actual situation.

In addition, the plurality of liquid inlet portions 10 are provided at different positions of the mixing portion 20, so that the impact force of the liquid on the mixing portion 20 can be further reduced, and the structural strength of the mixing portion 20 can be ensured.

Alternatively, in the case where a plurality of liquid intake portions 10 are provided, the number of liquid intake segments 101 of the partial liquid intake portions 10 is the same.

Note that, in the plurality of liquid inlet portions 10, the number of liquid inlet segments 101 of a part of the liquid inlet portions 10 is the same, and it can be understood that: the number of liquid inlet sections 101 of the plurality of liquid inlet portions 10 may be the same or different.

Under the condition that the quantity of the liquid inlet sections 101 of the liquid inlet parts 10 is different, on one hand, the assembly of the mixer in the use process is convenient, and on the other hand, when various liquids are mixed, the flow of the liquid which is conveyed at present can be met through the different liquid inlet sections 101 of the liquid inlet parts 10, and the cost is increased without setting too many liquid inlet sections 101.

In practical applications, the number of liquid inlet portions 10 and the number of liquid inlet segments 101 are determined according to practical situations, and are not limited herein.

Optionally, the mixing section 20 includes opposed first and second ends 202, 203; wherein, the first end 202 and the second end 203 may each be provided with a liquid inlet 10.

The first end 202 and the second end 203 of the mixing section 20 are understood to be that the first end 202 is close to the inlet of the mixing chamber 201 and the second end 203 is close to the outlet of the mixing chamber 201. Thus, both the first end 202 and the second end 203 may be provided with the liquid inlet 10, i.e. it is considered that the liquid inlet 10 may be provided on the inlet side of the mixing chamber 201 or on the outlet side of the mixing chamber 201.

Note that, the liquid inlet portion 10 is provided at each of the first end portion 202 and the second end portion 203, and when the liquid inlet portion 10 is only near or at the first end portion 202 and the second end portion 203, particularly when the liquid inlet portion 10 is provided at the second end portion 203, that is, at the outlet side, the liquid that does not flow out of the liquid inlet portion 10 immediately flows out of the outlet end 204 of the mixing portion 20.

In the case where the liquid inlet portion 10 is provided at each of the first end portion 202 and the second end portion 203, a mixing effect of a plurality of different liquids can be obtained. Illustratively, as shown in connection with fig. 2, the liquid flowing into the liquid inlet portion 10 near the second end portion 203 can be better mixed with the liquid flowing out of the two liquid inlet portions 10 under the downward impact force of the liquid flowing into the liquid inlet portion 10 near the first end portion 202, and the problem of opposite flushing can also be avoided.

Optionally, the mixer further comprises: the liquid outlet 30 communicates with the outlet 204 of the mixing section 20 so that the liquid mixed by the mixing section 20 flows out from the liquid outlet 301 of the liquid outlet 30.

The liquid mixed or filtered in the mixing section 20 is discharged through the liquid outlet section 30. Alternatively, the section of the liquid outlet 30 near the outlet end 204 of the mixing section 20 is a straight section. In this way, when the liquid in the mixing chamber 201 flows out, the liquid outlet resistance can be reduced, so that the liquid in the mixing chamber 201 is preferentially discharged from the liquid outlet portion 30, and further, the liquid in the mixing chamber 201 is prevented from flowing into the liquid inlet portion 10, that is, the liquid is prevented from flowing back.

Optionally, the liquid outlet 30 includes one or more liquid outlets 301, where the plurality of liquid outlets 301 are arranged in parallel.

In the case where the liquid outlet portion 30 includes a plurality of liquid discharge ports 301, various ways of conveying the liquid to the outside can be provided. That is, each drain 301 may correspond to an output pipeline and a destination. For example, when the mixer is used as a filter, at least two liquids can be output through the two liquid discharge ports 301 again after entering the mixer in sequence through the two liquid inlet portions 10 or the two liquid inlet sections 101, respectively, for filtration. Thus, the application range of the mixer is enlarged.

In the practical application process, the liquid outlets 301 of the liquid outlet portion 30 may be all or partially turned on.

The plurality of liquid discharge ports 301 are arranged in parallel, which is helpful for individual discharge of liquid and reduces resistance of liquid during discharge as much as possible.

Optionally, the sum of the flow areas of the plurality of liquid discharge ports 301 of the liquid outlet portion 30 is smaller than or equal to the flow area of the outlet end 204 of the mixing portion 20.

The sum of the flow areas of the liquid discharge ports 301 passing through the liquid discharge portion 30 is smaller than or equal to the flow area of the outlet end 204 of the mixing portion 20, so that, on one hand, the residence time of the liquid in the mixing chamber 201 can be prolonged before the liquid in the mixing chamber 201 is discharged, and on the other hand, when the liquid flows out from the liquid discharge portion 30, the flow rate of the liquid, that is, the flow efficiency of the liquid is increased, by reducing the flow area of the liquid.

Optionally, a filter device is provided within the liquid inlet portion 10 and/or the mixing portion 20.

The liquid in the liquid inlet portion 10 and/or the mixing portion 20 is filtered by the filtering means. In particular, the liquid inlet portion 10 is provided with a filtering device, and the filtering device is matched with the tesla valve structure for use, so that filtered liquid can continuously flow to the mixing portion 20, but cannot flow back, and therefore the liquid needs to be filtered again, and the working efficiency of the mixer is affected.

Alternatively, the filter device may be a filter mesh or a filter element body.

The above description and the drawings illustrate embodiments of the disclosure sufficiently to enable those skilled in the art to practice them. Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others.
