It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

In the description of the embodiments of the present application, the "top", "bottom", "height" orientation or positional relationship is the orientation or positional relationship in which the laundry treating apparatus and the catalytic device are normally used, for example, the orientation or positional relationship shown in fig. 1, 2, 3 and 5, it being understood that these terms are merely for convenience of description and simplicity of description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be taken as limiting the present application.

Referring to fig. 1 and 2, the clothes treatment apparatus includes a drum assembly 10, an ozone generator 20, and a catalytic device 30, the drum assembly 10 has a washing chamber, the catalytic device 30 includes a housing 31, a gas disperser 32, and a catalyst 33, the housing 31 is formed with a containing chamber 31a and an outlet 31b, the outlet 31b is communicated with the containing chamber 31a and the washing chamber, the catalyst 33 and the gas disperser 32 are both located in the containing chamber 31a, and the gas disperser 32 is communicated with the ozone generator 20 and is used for dispersing ozone from the ozone generator 20. Specifically, ozone and water react under the catalytic action of the catalyst 33 to generate a strongly oxidizing substance.

Strong oxidizing species are more oxidizing than ozone and include, but are not limited to, hydroxyl radicals and the like. Taking hydroxyl radicals as an example, the hydroxyl radicals have an extremely strong electron-donating ability, i.e., an oxidizing ability. The strong oxidizing property of the hydroxyl free radical enables the hydroxyl free radical to destroy the protein structure of bacteria or viruses to play a role in disinfection, and the hydroxyl free radical can also chemically react with pollutants to oxidize the pollutants into CO ₂ 、H ₂ O or inorganic salt, etc., and has no secondary pollution. Therefore, compared with ozone, the hydroxyl free radicals not only have stronger sterilization and disinfection effects, but also have stronger decontamination capability, and have no secondary pollution.

According to the clothes treatment equipment provided by the embodiment of the application, ozone from the ozone generator 20 is dispersed by the gas disperser 32 and then enters the accommodating cavity 31a, water liquid in the washing cavity can enter the accommodating cavity 31a, and ozone and water generate strong oxidizing substances such as hydroxyl radicals after catalytic reaction by the catalyst 33, so that the water liquid rich in the oxidizing substances such as ozone and hydroxyl radicals forms a mixture fluid together, and the sterilization, disinfection and decontamination effects are improved. The ozone is dispersed by the gas disperser 32 to form micro-bubbles, for example, bubbles with inner diameters in the micro-nanometer scale. Therefore, on one hand, the ozone is dispersed into the water liquid, the solubility of the ozone in the water liquid is improved, the concentration of the ozone is higher, the catalytic reaction rate can be improved, the catalytic reaction is accelerated, more hydroxyl radicals can be generated, and the concentration of the hydroxyl radicals is improved. On the other hand, the clothes are in fluid contact with the mixture rich in ozone and hydroxyl radicals, the disinfection and sterilization effects and the decontamination effects on the clothes are better, the hydroxyl radicals also have the function of preventing the clothes from color mixing, and the clothes can be prevented from color mixing when clothes with various colors are shuffled, so that the use of a user is more convenient, and the user experience can be improved.

In one embodiment, under certain test conditions, ozone is dispersed by the gas disperser 32 to achieve a hydroxyl radical concentration of about 0.31mMol in the aqueous liquid, thus greatly increasing the hydroxyl radical concentration.

The specific type of the laundry treating apparatus is not limited, and for example, the laundry treating apparatus may be a washing and drying machine or a washing machine, etc. The laundry treating apparatus may be a pulsator washing machine or a drum washing machine, etc.

Taking the clothes treatment equipment as an integrated washing and drying machine as an example, during washing, water liquid is arranged in the washing cavity and the accommodating cavity 31a, ozone enters the accommodating cavity 31a, at least part of ozone and water generate hydroxyl radicals after catalytic reaction through the catalyst 33, and the ozone and the hydroxyl radicals enter the washing cavity. Therefore, in the washing process, ozone and hydroxyl free radicals are in contact with clothes to achieve the purposes of disinfection, sterilization, decontamination and color fixation. During drying, no water liquid exists in the washing cavity, no water can be stored in the containing cavity 31a, and therefore ozone can be conveyed into the containing cavity 31a and does not generate catalytic reaction and directly enters the washing cavity, namely, the ozone is directly used for sterilization.

In one embodiment, referring to fig. 1, the bottom of the cylinder assembly 10 is formed with a water outlet communicated with the washing chamber, the catalytic device 30 is located outside the cylinder assembly 10 and disposed at the bottom side of the cylinder assembly 10, and the water outlet is communicated with the outlet 31b. The space outside the cylinder assembly 10 is large, which not only facilitates the loading and unloading of the catalytic device 30, but also facilitates the subsequent maintenance of the catalytic device 30. The catalytic device 30 is located at the bottom side of the cartridge assembly 10, and the catalytic device 30 is located at a lower position so that water flows smoothly into the accommodating chamber 31a through the drain port and the outlet 31b under the action of gravity. For example, when washing, the washing chamber holds water, the water surface naturally sinks over the holding chamber 31a, so that the catalyst 33 in the holding chamber 31a is immersed in the water, and ozone enters the holding chamber 31a and can fully contact with the water.

In one embodiment, referring to fig. 1 and 2, the clothes treating apparatus includes a drain line and a branch line both disposed at the bottom side of the drum assembly 10, wherein the drain line is connected to a drain port to drain water in the washing chamber, for example, when washing is completed, the water in the washing chamber is drained through the drain line. The branch pipe connects the drain line and the outlet 31b. On the one hand, at the beginning of washing, the washing intracavity begins to intake, because water drainage pipe, branch pipe and catalytic unit 30 all are located the lower water level department of barrel subassembly 10, like this, at the beginning of washing, even only a small amount of water in the barrel subassembly 10, also can ensure that there is water in branch pipe and the catalytic unit 30, can be full of water liquid in branch pipe and the catalytic unit 30 in the short time, ozone just can contact water and carry out catalytic reaction, the purpose of production hydroxyl free radical. In the drainage process, water can be kept in the accommodating cavity 31a until the drainage is finished, that is, in the whole washing process, water in the accommodating cavity 31a is contacted with the catalyst 33 and ozone, so that hydroxyl radicals can be generated in the whole washing process, the content and the concentration of ozone and the hydroxyl radicals in water liquid can be increased, and the disinfection and sterilization effect is improved. On the other hand, the design can flexibly arrange the catalytic device 30 in the limited space of the clothes treatment equipment by communicating the water outlet and the outlet 31b through the branch pipe on the basis of not changing the structural arrangement and the pipe arrangement of the original clothes treatment equipment as much as possible.

The structure of the drain pipeline is not limited, and in an exemplary embodiment, the drain pipeline includes a drain pipe and a drain valve disposed on the drain pipe, the drain valve is used for opening or closing the drain pipeline, and the branch pipe is located upstream of the drain valve and is communicated with the drain pipe. During washing, the drain valve closes the drain water path, and the portion of the drain pipe located upstream of the drain valve is still filled with water, so that water from the drain pipe enters the accommodating chamber 31a during washing.

In one embodiment, referring to fig. 1 and 2, the clothes treating apparatus includes an air pump 40, and the air pump 40 is connected to the ozone generator 20 to drive the flow of ozone. The air pump 40 pumps ozone into the accommodating cavity 31a, the flow rate of the ozone is high, and the ozone can stir the water liquid in the accommodating cavity 31a to flow, so that the mixture fluid can keep flowing conveniently, and the dissolving speed of the detergent can be improved. The air pump 40 is used for pumping the ozone, so that the flow rate of the ozone can be controlled, for example, by adjusting the pressure of the air pump 40 to adjust the flow rate of the ozone, thereby controlling the reaction efficiency of the catalytic reaction to a certain extent. The positive pressure is formed at the side of the ozone generator 20, so that water in the washing chamber can be prevented from flowing back to enter the ozone generator 20, that is, the air pump 40 can also play a role in limiting the water flow direction, and thus, structures such as a one-way valve can be avoided. In addition, because the ozone generator 20 is located at a positive pressure side, fine objects such as lint in the water flow are not easy to enter the ozone generator 20 or enter the ozone conveying pipeline. Even if fine objects such as flocks and the like enter the ozone conveying pipeline, the objects blocking the conveying pipeline can be blown out by the pressure of the air pump 40, so that the smoothness of the conveying pipeline is ensured. Therefore, the number of parts is reduced and the structure and the control method are simplified by using the air pump 40.

The location of the ozone generator 20 on the clothes treating apparatus is not limited, and in an exemplary embodiment, referring to fig. 1, the ozone generator 20 is located outside the drum assembly 10 and is disposed on the top of the drum assembly 10. Therefore, the ozone generator 20 is located at a higher position of the cylinder assembly 10, water flow is difficult to flow back into the ozone generator 20, accordingly, impurities such as flocks and the like in water liquid are difficult to enter the air conveying pipeline of the ozone generator 20, the air conveying pipeline is prevented from being blocked to a certain extent, and the stability and the reliability of the clothes treatment equipment are improved.

In one embodiment, referring to fig. 5 and 6, the housing 31 is formed with an inlet 31c, the inlet end of the gas disperser 32 is connected to the inlet 31c, the inlet 31c is connected to the outlet end of the ozone generator 20 through a gas pipe, and the ozone from the ozone generator 20 can be transferred into the gas disperser 32 through the gas pipe and the inlet 31 c.

The structure of the barrel assembly 10 is not limited, and for example, in an embodiment, the barrel assembly 10 includes an inner barrel and an outer barrel, the inner barrel is rotatably sleeved in the outer barrel, a space in the inner barrel is a washing chamber, a peripheral wall of the inner barrel is formed with a plurality of water through holes, the water through holes communicate the washing chamber with a space in the outer barrel, the outer barrel is used for containing water, and a water outlet is formed on the outer barrel. When washing, the washing cavity is filled with clothes, and the inner space of the outer barrel is filled with water liquid. When the water is drained, for example, after the washing is finished, the water in the outer tub is drained through the drain outlet.

The specific structure of the gas disperser 32 is not limited, and the gas disperser 32 includes, but is not limited to, nozzles, aeration membranes, aerators, and the like, and the specific type of aerator is not limited, for example, the aerator may be a tube or disc aerator.

In one embodiment, the gas disperser 32 comprises a body having a plurality of pores formed therethrough. Ozone enters the containing cavity through the micropores, the ozone is in strong contact with water around the micropores, and mass transfer is carried out on gas-phase ozone to liquid-phase water, so that a plurality of micro bubbles are formed. The micro-bubbles have small bubble diameter, large gas-liquid interface area and uniform bubble diffusion, so that the size of the bubbles is reduced, the number of the bubbles is increased, the turbulence degree of water liquid is improved, and the ozone solubility is improved.

In one embodiment, the plurality of microwells are arranged in an array. The plurality of micropores can disperse ozone, the pore diameter of the micropores is small, the number of the micropores is large, and the ozone solubility is further improved.

The pore size of the micropores is not limited, and, for example, in one embodiment, the pore size of the micropores is not greater than 100 μm (micrometers).

In one embodiment, referring to fig. 1 and 2, the gas disperser 32 comprises a gas housing 321 having a gas outlet and an aeration membrane, the gas housing 321 is in communication with the ozone generator 20, and the aeration membrane covers the gas outlet to disperse ozone. The inner space of the air shell 321 is used for containing a certain volume of ozone, and the ozone is aerated by the aeration membrane to achieve the purpose of dispersing the ozone.

The aeration membrane is a permeable compact membrane, and a plurality of aeration holes are densely distributed on the aeration membrane. In this way, the ozone is dispersed into fine bubbles by the aeration holes.

The pore size of the aeration holes is not limited, and is, for example, between 0.1 and 0.4 μm.

The type of the aeration film is not limited, and for example, the aeration film may be a silicone rubber film or a hydrophobic polymer film, or the like. Thus, the aeration membrane has a certain elastic force, and in one embodiment, the aeration membrane is wrapped around the air outlet of the air casing 321. Therefore, in the process that the ozone flows out from the air outlet, the ozone forces the aeration membrane to deform, and then the aeration holes are enlarged, so that the ozone flows out through the aeration holes. When ozone stops carrying, the deformation is recovered to the aeration membrane, and the aeration hole recloses, can effectually prevent like this that external water from pouring into in the gas shell 321 through the aeration hole.

The shape of the air shell 321 is not limited, and for example, in one embodiment, referring to fig. 2, the air shell 321 is a flat disk. For example, the projection shape of the air shell 321 along the height direction of the housing 31 includes, but is not limited to, a circle, an ellipse, a polygon, and the like. That is, the cross-sectional shape of the air shell 321 is substantially circular, elliptical, polygonal, or the like, and the height dimension of the air shell 321 is much smaller than the cross-sectional area thereof. Thus, the outer surface area of the air shell 321 is large, and the area of the air shell 321 for arranging the aeration membrane is large, so that the air output of ozone is increased; the air shell 321 has a small height dimension, so as to avoid occupying too much space in the height direction of the housing 31.

The position of the gas disperser 32 is not limited, and for example, in an embodiment, referring to fig. 2, the gas disperser 32 is located at the bottom of the accommodating chamber 31a, and the outlet 31b is located at the top of the housing 31 and formed on the peripheral sidewall of the housing 31. So design, no matter whether water liquid is full of holds chamber 31a, hold the bottom of chamber 31a and all have water liquid, ozone from holding the bottom of chamber 31a to holding the top motion of chamber 31a to make ozone, water and catalyst 33 three fully contact, ozone and the hydroxyl radical that produces can smoothly flow out from the export 31b that is located the top of casing 31 because density is less. The outlet 31b is formed on the peripheral side wall of the casing 31, and can minimize the space occupied by the casing 31 in the height direction of the clothes treatment device, so that the internal structure of the clothes treatment device is more compactly arranged.

In one embodiment, referring to fig. 2, 5 and 8, the catalytic device 30 includes a partition 34 disposed in the accommodating chamber 31a, the partition 34 is formed with a plurality of through holes 34a, the partition 34 divides the accommodating chamber 31a into a first chamber 31a 'and a second chamber 31a ", the gas disperser 32 is located at one side of the first chamber 31a', and the outlet 31b is located at one side of the second chamber 31 a". A catalyst 33 is located in the second chamber 31a ". The first chamber 31a ' provides sufficient mixing space and time for the ozone and the water solution, after the ozone and the water solution are sufficiently mixed, the ozone and the water solution enter the second chamber 31a ' through the through hole 34a, and the ozone and the water solution are catalyzed by the catalyst 33 in the second chamber 31a ' to generate hydroxyl radicals. Thus, mixing before catalysis, the reaction rate is faster and the reaction is more complete.

In one embodiment, referring to fig. 3 to 5, the housing 31 is cylindrical, the axial direction of the housing 31 is the same as the top-bottom direction thereof, the partition 34 is substantially disc-shaped, and the partition 34 is disposed along the radial direction of the housing 31, so that the first chamber 31a' and the second chamber 31a ″ are both substantially cylindrical cavities.

The type of the catalyst 33 is not limited, and for example, in one embodiment, referring to fig. 2, the catalyst 33 is in the form of particles, and the particles of the catalyst 33 are filled in the second chamber 31a ″.

In one embodiment, referring to fig. 5-7, the catalytic device 30 includes baffles 35 disposed within the second chamber 31a ". The baffle 35 can change the flow direction, flow rate, etc. of the mixture fluid of ozone, water stream and hydroxyl radicals, etc. to generate turbulence in the second chamber 31a ″ to increase the contact time, contact times, reaction time, etc. of ozone, water stream and the catalyst 33. Thus, the reaction of ozone and water liquid is more complete and full, and the total amount and concentration of hydroxyl radicals are increased.

In one embodiment, referring to fig. 5 to 7, the baffle 35 is formed with a plurality of through holes 35a. The overflowing holes 35a help to ensure smooth flow of the mixture fluid.

In one embodiment, referring to fig. 5 to 7, the baffle 35 is spaced apart from the peripheral sidewall of the second chamber 31a ″ to form a flow passing region 35b. The baffle 35 may be fixed to the peripheral side wall of the second chamber 31a ", and the baffle 35 may also be fixed to the partition 34. On one hand, a mixture fluid formed by ozone, water flow, hydroxyl radical and the like can flow through the flow passing hole 35a and the flow passing area 35b, the flow rate of the mixture fluid flowing through the flow passing area 35b and the flow passing hole 35a is different, specifically, the flow passing area of the flow passing area 35b is different from the flow passing area of the flow passing hole 35a, for example, the flow passing area of the flow passing area 35b is larger, the flow passing area of the flow passing hole 35a is smaller, and the surrounding part of the flow passing hole 35a can block the flow of the mixture fluid, so that the flow rate and the flow direction of the mixture fluid respectively flowing through the flow passing area 35b and the flow passing hole 35a are different, the flow field of the mixture fluid in the mixing cavity generates turbulence, the mixture fluid performs irregular movement, for example, a component velocity perpendicular to the baffle 35 is generated, and thus, the mixture fluid flows from the gas disperser 32 to the outlet 31b along a zigzag path, the contact time, the contact frequency, the reaction time and the like of the ozone, the water and the catalyst 33 are increased, so that the reaction of the ozone and the water solution can be more thoroughly and the total amount and the concentration of the hydroxyl radical are increased. On the other hand, the solubility of ozone and hydroxyl radicals in water is easy to reach a saturated state under the conditions of certain temperature and the like, the overflowing holes 35a and the overflowing areas 35b are convenient for the mixture fluid to circulate, and the fluid is ensured to have a certain outflow rate under the condition of changing the flowing direction of the mixture fluid, so that the baffle plates 35 are prevented from excessively hindering the movement of the fluid, and the hydroxyl radicals are ensured to be fully dissolved into the water flow and enter the washing cavity along with the water flow.

The flow area refers to a cross-sectional area perpendicular to the fluid flow direction.

In one embodiment, referring to fig. 2, the angle α between the baffle 35 and the partition 34 is less than 90 degrees. For example, the angle α between the baffle 35 and the partition 34 is 0 degrees, i.e., the baffle 35 is parallel to the partition 34. Also for example, the angle α between the baffle 35 and the partition 34 is 45 degrees. Therefore, the mixture fluid contacts the baffle plate 35 at a certain angle, the baffle plate 35 can slightly slow down the flow velocity of the mixture fluid, the retention time of the mixture fluid is prolonged, the catalytic reaction time is prolonged, the excessive reduction of the flow velocity of the mixture fluid can be avoided, and the baffle plate 35 can keep a certain flow velocity to flow.

In an embodiment, referring to fig. 2 and 5, the number of the baffle plates 35 is multiple, and the baffle plates 35 are arranged at intervals in a staggered manner along the height direction of the shell 31. That is, the plurality of baffles 35 are formed with a plurality of flow passing regions 35b, and the plurality of flow passing regions 35b are arranged in layers at intervals in the height direction of the casing 31. The flow path of the mixture fluid is tortuous and variable, so that the mixture fluid has more abundant flow paths during flowing from the gas disperser 32 to the outlet 31b, for example, part of the mixture fluid may circulate through the through-flow holes 35a of the respective layers of the baffles 35; for another example, a portion of the mixture fluid may flow through each of the flow-through regions 35b; as another example, a portion of the mixture fluid may pass through the flow-through region 35b and the flow-through hole 35a in sequence, and so on, such that the mixture fluid is forced to cross-flow through the second chamber 31a multiple times in multiple paths, with a greatly increased degree of turbulence.

In an embodiment, referring to fig. 2 and fig. 5, projections of two adjacent flow-passing areas 35b along a height direction of the housing 31 are at least partially non-overlapping. That is, two adjacent flow-through regions 35b are arranged in a staggered manner, and illustratively, two adjacent flow-through regions 35b are arranged in a staggered manner in the radial direction of the housing 31. Thus, the turbulence generated by the flow field of the mixture fluid is further enhanced, the moving path of the mixture fluid is more tortuous and diversified, the mixture fluid does irregular movement, and the contact time, the contact times, the reaction time and the like of the ozone, the water and the catalyst 33 are further increased, so that the ozone and the water react more thoroughly and fully, and the total amount and the concentration of the hydroxyl radicals are increased.

The extent to which the projections of the two adjacent flow-passing regions 35b along the height direction of the housing 31 do not overlap at least partially is not limited, and in an exemplary embodiment, the projections of the two adjacent flow-passing regions 35b along the height direction of the housing 31 do not overlap only partially. That is, the projections of the two adjacent flow-passing areas 35b along the height direction of the housing 31 are partially overlapped, and the projections of the two adjacent flow-passing areas 35b along the height direction of the housing 31 are partially not overlapped. In another embodiment, referring to fig. 2 and fig. 5, the projections of two adjacent flow-passing areas 35b along the height direction of the housing 31 do not overlap at all. That is, the projections of the two adjacent flow-through regions 35b along the height direction of the housing 31 are separated at intervals, and the projections of the two adjacent flow-through regions 35b along the height direction of the housing 31 do not have an overlapping region. This further forces the mixture flow to change flow direction and flow path, making the reaction more complete.

In one embodiment, referring to fig. 2, 5-7, the catalytic device 30 includes a baffle 36 disposed in the second chamber 31a ", and the baffle 36 is a non-porous structure. The mixture fluid can only flow around the baffle plate 36 and not through the baffle plate 36. Thus, the baffle plate 36 can obstruct the mixture flow to a greater extent, so as to increase the retention time of the mixture flow in the second chamber 31a ″ to a greater extent, and the catalytic reaction can be more complete.

It will be appreciated that the baffle 36 can impede the flow of the mixture fluid to some extent, but does not impede the flow of the mixture fluid, i.e., the outer periphery of the baffle 36 is a space through which the mixture fluid can flow.

In one embodiment, referring to fig. 2, 5-7, a baffle plate 36 is positioned between the inner surface of the second chamber 31a "and the baffle plate 35 closest to the outlet 31b. For example, the baffle plate 36 is located between the inner top surface of the second chamber 31a ″ and the baffle plate 35 at the highest position. That is, the baffle plate 36 is disposed close to the outlet 31b, on one hand, the baffle plate 36 can effectively prevent the mixture fluid from directly flowing out of the outlet 31b, and the residence time of the mixture fluid is prolonged; on the other hand, the baffle plate 36 is prevented from interfering excessively with the flow of the mixture fluid to some extent, and the flow rate of the mixture fluid is prevented from being reduced sharply, so that the mixture fluid can flow smoothly and in multiple paths in the second chamber 31a ″.

The number of the flow blocking plates 36 is not limited, and in an exemplary embodiment, the number of the flow blocking plates 36 is one. In another embodiment, referring to fig. 2 and 5, the number of the flow baffles 36 is multiple, for example, two, and the flow baffles 36 are arranged in a staggered manner. For example, the baffle plates 36 are arranged in a staggered manner in a direction perpendicular to the height direction of the housing 31. For example, the baffle plates 36 are arranged in a staggered manner in the radial direction of the casing 31. In this way, the plurality of baffle plates 36 function to block the flow of the mixture fluid multiple times, which can more effectively extend the residence time of the mixture fluid in the second chamber 31a ″.

The specific location of the flow baffle 36 is not limited, and referring to fig. 2, 5 to 7, in an embodiment, the flow baffle 36 is fixedly connected to the inner circumferential wall of the housing 11. That is, the baffle plate 36 is fixed to the inner surface of the second chamber 31a ", for example, the baffle plate 36 is fixed to the inner top surface of the second chamber 31 a". In one embodiment, the baffle 36 is perpendicular to the baffle 35. That is, the baffle plate 35 is fixed with a baffle plate 36, for example, the baffle plate 36 is fixed on the top surface of the baffle plate 35. This facilitates, on the one hand, the fixing of the baffle plate 36 and, on the other hand, the re-change of the direction of the mixture flow flowing through the baffle plate 35 by the baffle plate 36, which increases the turbulence of the mixture flow.

In one embodiment, the angle between the baffle plate 36 and the baffle plate 34 is greater than 0 degrees. That is, the baffle 36 is not parallel to the separator 34. For example, the angle between the baffle plate 36 and the baffle plate 34 is 45 degrees. Thus, the baffle plate 36 is inclined so that the mixture flow has a suitable flow rate and residence time.

In one embodiment, referring to fig. 2 and 5, the angle between the baffle plate 36 and the partition plate 34 is 90 degrees, i.e. the baffle plate 36 is perpendicular to the partition plate 34. The second chamber 31a "is provided with a baffle 36 on the top surface, and the baffle 35 at the highest position is also provided with a baffle 36. The flow rate of the mixture fluid is relatively high at a position away from the outlet 31b, for example, the bottom of the second chamber 31a ", and the flow rate of the mixture fluid is relatively low at a position close to the outlet 31b, for example, the bottom of the second chamber 31 a". The mixture fluid flowing at high speed passes through the baffle 35 and the flow passing area 35b, etc., and the mixture fluid moving in multiple directions flows to a position close to the outlet 31b, and is discharged from the outlet 31b after being temporarily retained by the baffle 36.

In one embodiment, referring to fig. 5, the minimum distance L between the baffle 36 and the center line E of the shell 31 is not less than one sixth of the minimum inner diameter of the shell 31. For example, the housing 31 is generally cylindrical, and the minimum distance L between the baffle 36 and the centerline E of the housing 31 is greater than or equal to one sixth of the minimum inner diameter of the housing 31, so that the baffle 36 is located closer to the central region of the housing 31 for better adjustment of the flow direction of the mixture fluid.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
