Referring to fig. 1, a laundry treating apparatus includes a laundry treating drum 300, a front support 200 disposed at a front end of the laundry treating drum 300, and a spraying system according to any embodiment of the present application.

The laundry treating drum 300 has a laundry treating chamber 300a. The laundry treating chamber 300a is for placing laundry. The front side of the laundry treating chamber 300a is opened.

The front supporter 200 has a laundry inlet 200a. The laundry introduction port 200a communicates with the laundry treating chamber 300a.

The clothes treating apparatus includes a front sealing plate disposed at a front side of the front supporter 200, and a door body having a front surface as an appearance surface of the clothes treating apparatus. The front closing plate is provided with a doorway aligned with the laundry entrance 200a, and the door body is used to open and close the doorway.

Illustratively, the laundry treating apparatus further includes a door gasket coupled between the doorway of the front sealing plate and the laundry access opening 200a of the front support for sealing a gap therebetween. When the door is closed, the laundry treating chamber 300a forms a relatively closed space. Referring to fig. 7, 8 and 13, the injection device 100 includes a body and a branch pipe 3.

Referring to fig. 10 and 12, the first end of the body has the injection port 133b, and the branch pipe 3 is connected to one side of the body, i.e., to an arbitrary portion on the circumferential side of the first injection part 1.

Referring to fig. 10 and 11, the body is provided with a first fluid medium inlet 2a', from which the first fluid medium enters the interior of the injection device 100.

Referring to fig. 10 and 11, the branch tube 3 is provided with a second fluid medium inlet 3a'. The second fluid medium enters the interior of the jetting device 100 from the second fluid medium inlet 3a'.

The spray device 100 is used for mixing the first fluid medium and the second fluid medium and spraying mist from the spray port 133b to the laundry in the laundry treating chamber 300a.

Referring to fig. 6, the front support 200 has a through hole 200b. The body portion passes through the through hole 200b and protrudes into a side of the front supporter 200 toward the laundry treatment chamber 300a, and the branch pipe 3 is located outside the front supporter 200.

Wherein, the outer side of the front supporter 200 refers to a side of the front supporter facing away from the laundry loading port 200a or from the laundry treating chamber 300a. Specifically, when the door is closed, the outer side of the front supporter 200 is positioned outside the closed space formed by the laundry treating chamber 300a and the laundry introduction opening 200a.

The clothes treatment equipment provided by the embodiment of the application can introduce the dry cleaning agent into the first fluid medium inlet or the second fluid medium inlet, so that dry cleaning of clothes is realized.

In the clothes treatment apparatus of the embodiment of the application, the front support 200 provides an installation position for the spraying device 100, so that the problem that the spraying device 100 is inconvenient to install is solved; because the branch pipe 3 is arranged on the outer side of the front support 200, only one through hole 200b for penetrating the body needs to be arranged on the front support 200, and the branch pipe 3 is not required to be accommodated in a groove or a hole on the front support 200, so that the installation is convenient. In addition, the connection of the first fluid medium inlet with its corresponding conduit, and the connection of the second fluid medium inlet with its corresponding conduit, can both be operated outside the front support 200, having a larger operating space; the sealing performance of the joint of the first fluid medium inlet and the corresponding pipeline and the sealing performance of the joint of the second fluid medium inlet and the corresponding pipeline can be visually observed by an operator, so that the daily maintenance and overhaul are facilitated.

The clothes treatment equipment of the embodiment of the application, the spraying device can directly spray atomized dry cleaning agent to the clothes in the clothes treatment cylinder 300, and the drying system is not required to carry, so that the dry cleaning agent has sufficient contact time with the clothes, the utilization rate of the dry cleaning agent is improved, and the dry cleaning effect is improved.

Referring to fig. 1 and 2, the through hole 200b and the injection device 100 are exemplarily located above the laundry access opening 200a. Thus, after the mist is sprayed from the spray port 133b, the mist is scattered farther in the front-rear direction in the laundry treatment chamber 300a, and the mist covers a wider range, so that the medium in the mist can be better brought into contact with the laundry.

Exemplarily, referring to fig. 7, 8 and 13, the body includes a first injection part 1 and a second injection part 2. The first end of the first injection part 1 has an injection port 133b, and the second injection part 2 is connected to the second end of the first injection part 1. The branch pipe 3 may be connected to the first injection part 1 or to the second injection part 2.

Referring to fig. 6, when the injection device 100 extends into the front support 200, the first injection part 1 is disposed obliquely with respect to the horizontal plane, and the first end of the first injection part 1 is inclined downward, wherein the first end of the first injection part 1 is an end far from the second injection part 2, that is, an end where the injection port 133b is located. The second ejection parts 2 are arranged in the front-rear direction in the horizontal plane. That is, the first injection part 1 and the second injection part 2 form a bent structure, and the first injection part 1 extends obliquely rearward and downward from the rear end of the second injection part 2.

Since the laundry is easily accumulated at the lower portion of the laundry treating chamber by gravity, the injection port 133b is inclined downward, and the mist such as the dry cleaning agent from the injection port 133b can fall in a parabolic shape by its initial speed and gravity, so that the liquid such as the dry cleaning agent is more dispersed to cover the laundry of the laundry treating chamber more widely, facilitating the liquid such as the dry cleaning agent to be directly attached to the laundry, thereby improving the cleaning effect.

It is understood that mist refers to a dispersion of liquid in the form of droplets of particulate form. Illustratively, the diameter of the atomized droplets may be no greater than 50 μm. This is only one example diameter of a mist of droplets.

For example, referring to fig. 11, an included angle β formed between the extending direction of the first injection part 1 and the extending direction of the second injection part 2 is 110 ° to 150 °. For example, 110 °, 113 °, 120 °, 125 °, 130 °, 137 °, 140 °, 144 °, 150 °. This angle range allows the mist sprayed from the atomizing core 13 to be sprayed to the laundry in the laundry treating chamber 300a more obliquely downward.

Illustratively, the branch pipes 3 and the second ejection parts 2 are arranged in parallel, i.e., the branch pipes 3 are arranged in the front-rear direction. In this way, it is convenient to collectively externally connect the piping on the second jetting parts 2 and the branch pipes 3 from the front side of the front support 200.

Illustratively, referring to fig. 1 and 2, the anterior support 200 includes a collar portion 2001 and a surrounding portion 2002. The bobbin portion 2001 defines a laundry access opening 200a. It should be noted that in a planar projection perpendicular to the axis of laundry treatment drum 300, laundry access opening 200a is located within the projection range of the front side opening of laundry treatment drum 300, i.e. laundry access opening 200a is smaller than the inner diameter of laundry treatment drum 300.

The surrounding portion 2002 extends from the axial rear end of the drum ring portion 2001 to the front edge of the laundry treatment drum 300, and the surrounding portion 2002 is substantially trumpet-shaped. The radially outer end of the surrounding portion 2002 is for rotatably engaging with the laundry treating drum 300.

Referring to fig. 6, the through hole 200b penetrates the surrounding portion 2002. That is, the injection device 100 passes through the surrounding portion 2002 from front to back.

Referring to fig. 7, 8 and 13, the spraying device 100 includes a position-limiting plate 4, and the position-limiting plate 4 is used for abutting against a portion around the through hole 200b on the front surface of the front support 200. After the first spraying part 1 is inserted into the through hole 200b, the limiting plate 4 abuts against the front surface of the front support 200 to prevent the spraying device 100 from being continuously inserted into the through hole 200b, so that the spraying device 100 can be quickly inserted in place.

In some embodiments, the retainer plate 4 is provided with a coupling hole through which a fastener such as a screw is inserted and screwed into the front support 200, so that the injection device 100 can be mounted on the front support 200.

In some embodiments, the restriction plate 4 is provided on the outer surface of the first ejection part 1.

In other embodiments, a restriction plate 4 is provided on the outer surface of the second ejection portion 2 and/or the branch pipe 3.

The structure of the stopper plate 4 is not limited.

For example, in some embodiments, referring to fig. 13, the plate surface of the limiting plate 4 is perpendicular to the extending direction of the second spraying portion 2, referring to fig. 6, a boss 2002 'is formed on the front surface of the surrounding portion 2002, and the through hole 200b penetrates through the boss 2002'. The boss 2002' has a vertically positioned face 2002a. The stopper plate 4 abuts against the vertical positioning surface 2002a. In this manner, it can be ensured that the second jetting parts 2 and the branch pipes 3 are arranged substantially horizontally in the front-rear direction.

In other embodiments, the front support 200 has an inclined mounting surface around the through hole 200b, the plate surface of the limit plate 4 is perpendicular to the extending direction of the first injection part 1, and the limit plate 4 abuts against the inclined mounting surface. In this way, it can be ensured that the second ejection portions 2 and the branch pipes 3 are arranged substantially horizontally in the front-rear direction.

When the atomizing core 13 is clogged or aged, the atomizing core 13 is taken out while the cover 12 is opened, and a new integral member of the atomizing core 13 and the cover 12 is replaced.

In the spraying device 100 of the embodiment of the application, the mounting direction of the cover body 12 is the same as that of the atomizing core 13, and the spraying device is assembled along the length direction of the atomizing core 13, so that the atomizing core 13 and the cover body 12 can be assembled and disassembled conveniently; the atomizing core 13 is convenient to replace and maintain.

For example, referring to fig. 10 and 11, the body has a first flow channel 2a therein, the branch tube 3 has a second flow channel 3a therein, and an outlet 3a ″ of the second flow channel 3a is disposed on a sidewall of the first receiving groove 11 a. A part of the circumferential surface of the shaft section of the atomizing core 13 is spaced from the inner wall of the mounting chamber 1a and forms a liquid inlet passage which communicates the outlet 3a ″ of the second flow channel 3a and the inner space of the atomizing core 13.

In the embodiment, the dry cleaning agent enters the liquid inlet passage from the second flow passage 3a, flows along the liquid inlet passage, finally enters the inner space of the atomizing core 13, and is mixed with the gas from the first flow passage 2a in a gas-liquid two-phase manner, so that the liquid inlet passage plays a role of a flow passage of the dry cleaning agent, the dry cleaning agent from the second flow passage 3a is guided to the atomizing core 13, an independent passage is avoided, the structure is simplified, and the structure of the injection device is simpler and more compact; in addition, the dry cleaning agent can flow along the circumferential surface of the atomizing core 13, so that more flow paths can be provided, and the flow of the dry cleaning agent is facilitated.

For example, referring to fig. 10 and 12 in combination, along the length direction of the atomizing core 13, the liquid inlet path includes a premixing area 1b and a flow control area 1c, and the flow cross-sectional area of the premixing area 1b is larger than that of the flow control area 1 c. The flow control area 1c has a small flow cross-sectional area and is used for controlling the flow of the dry cleaning agent entering the inner space of the atomizing core 13, that is, the flow of the dry cleaning agent can be controlled by controlling the fitting clearance between the atomizing core 13 and the inner wall of the mounting chamber 1a, thereby facilitating the control of the precision. It should be noted that, the atomizing core 13 itself has a smaller size, and the size of the internal flow passage of the atomizing core 13 is smaller, if the flow rate of the dry cleaning agent is controlled by controlling the precision of the small holes on the atomizing core 13, the processing difficulty is greater, and the processing cost is obviously increased.

The outlet 3a' of the second flow passage 3a is arranged on the side wall of the premixing area 1b, the injection device is provided with an air inlet micro-channel, and the air inlet micro-channel is communicated with the premixing area 1b and the external environment of the injection device, so that the dry cleaning agent can realize gas-liquid two-phase premixing in the premixing area 1 b.

The dry cleaning agent in the second flow passage 3a is basically a continuous liquid phase, the liquid dry cleaning agent enters the premixing area 1b, and is subjected to primary premixing with air in the premixing area 1b to form a gas-liquid premixed two-phase flow. It will be appreciated that the dry cleaning agent, when entering the inner space of the atomizing core 13, will undergo secondary premixing with the air flow from the first flow passage 2a. The primary premixing provides favorable conditions for the secondary premixing, and the dry cleaning agent can be conveniently and fully mixed with air during the secondary premixing.

The inlet microchannels only allow the gas flow from the outside into the premixing zone 1b, while the liquid in the premixing zone 1b does not flow to the outside environment through the inlet microchannels.

It can be understood that, as the gas-liquid two-phase flow in the liquid inlet passage continuously flows to the inner space of the atomizing core 13, the premixing area 1b forms negative pressure to continuously suck the external air from the air inlet micro-channel, thereby realizing continuous premixing of the continuous dry cleaning agent.

Illustratively, the extending direction of the end of the second flow channel 3a and the length direction of the atomizing core 13 form an angle of 30 ° to 90 °, for example, 30 °, 35 °, 45 °, 60 °, 80 °, 90 °, and the like.

In this embodiment, when liquid dry cleaning agent flowed to premixing district 1b from second runner 3a, liquid dry cleaning agent was under the effect of flow inertia, around atomizing core 13 spiral advancing, so, liquid dry cleaning agent can be drawn into more spaces, forms tiny liquid pearl, and the air content is better, mixes the effect in advance better.

For example, in some embodiments, the end of the second flow channel 3a extends at an angle of 40 ° to 60 ° with respect to the length of the atomizing core 13.

Referring to fig. 9 and 11, the atomizing core 13 has a venturi flow channel 13a and a venturi negative pressure suction opening 133a, and the nozzle 133b is formed at the end of the venturi flow channel 201.

The second ejection parts 2 independently define the first flow passage 2a, or the second ejection parts 2 and a part of the housing 11 together define the first flow passage 2a. The outlet of the first flow channel 2a communicates with the inlet of the venturi flow channel 13a, and the inlet of the first flow channel 2a is the first fluid medium inlet 2a' described above. That is, the first fluid medium inlet communicates with the inlet of the venturi flow passage 201 through the first flow passage 2a.

The second flow path 3a communicates with the venturi negative pressure suction port 133a, and the inlet of the second flow path 3a is the second fluid medium inlet 3a' described above.

For example, the first fluid medium is introduced into the first flow passage 2a and flows through the venturi flow passage 13a, during the process of flowing through the venturi flow passage 13a, a negative pressure is generated at the venturi negative pressure suction port 133a based on the venturi effect, the second fluid medium in the second flow passage 3a is sucked into the venturi flow passage 13a from the second flow passage 3a under the negative pressure, and the first fluid medium and the second fluid medium are ejected from the ejection port 133b of the atomizing core 13 together.

In the spraying device 100 of the embodiment of the application, the venturi negative pressure suction port 133a and the spraying port 133b are both concentrated on the atomizing core 13, the atomizing core 13 is equivalent to a venturi tube, the size, shape and the like of the flow channel inside the atomizing core 13 and the spraying port 23b, the atomizing core 13 determines the form and the spraying speed of the sprayed mist, and the assembling error of the shell 11, the cover 12 and the atomizing core 13 has relatively small influence on the spraying effect, so that the spraying device 100 can have better batch consistency by only controlling the batch consistency of the atomizing core 13.

In some embodiments, the atomizing core 13 and the cover 12 are non-detachably connected, for example, integrally injection molded, or integrally formed metal. The atomizing core 13 is also removed simultaneously with the opening of the cover 12.

In other embodiments, the atomizing core 13 is removably attached to the cover 12. When the atomizing core 13 needs to be replaced, the cover body 12 is opened first, and then the atomizing core 13 is taken out, or the atomizing core 13 is connected to the cover body 12, and when the cover body 12 is taken down, the atomizing core 13 is taken down along with the cover body 12, and then the atomizing core 13 is detached from the cover body 12. In this way, when the atomizing core 13 is replaced, the cover 12 does not need to be replaced.

The material of the atomizing core 13 is not limited, and may be, for example, ceramic, plastic, or the like.

Illustratively, the atomizing core 13 is a metal piece, that is, the atomizing core 13 is made of a metal material. So, be convenient for control atomizing core 13's size in manufacturing process, metal material can control better size precision and error in the course of working, ensures atomizing core 13's size precision and batch uniformity.

Illustratively, the atomizing core 13 is a one-piece structure. Of course, the atomizing core 13 may be a split structure.

Illustratively, the cover 12 is a one-piece structure, e.g., integrally injection molded. The cover body 12 of the integrated type can reduce the number of parts and assembly time and improve the assembly efficiency

Of course, the cover 12 may be a split structure.

Illustratively, the housing 11, the second injection part 2 and the branch pipe 3 are of an integral structure, for example, are integrally injection-molded, so that the number of parts can be reduced, the assembly time can be reduced, and the assembly efficiency can be improved.

For example, referring to fig. 10, the cover 12 has a second receiving groove 12a, and the second receiving groove 12a and the first receiving groove 11a are butted along the length direction of the atomizing core 13.

Referring to fig. 9, a portion of the atomizing core 13 is inserted into the first receiving groove 11a, and another portion of the atomizing core 13 is inserted into the second receiving groove 12 a. That is, the first accommodation groove 11a and the second accommodation groove 12a together define the installation cavity 1a for installing the atomizing core 13, and thus, the cover body 12 and the housing 11 together accommodate the atomizing core 13, taking into account the dimensions of the housing 11 and the cover body 12 in the length direction of the atomizing core 13.

The venturi negative pressure suction port 133a is provided at an end of the atomizing core 13 in the second housing groove 12a near the ejection port 133b.

The mounting and positioning manner of the cover 12 in the first receiving groove 11a and the second receiving groove 12a is not limited.

For example, referring to fig. 9, the groove bottom of the first accommodation groove 11a has a first positioning surface 11b surrounding the outlet of the first flow channel 2a, the groove bottom of the second accommodation groove 12a has an escape opening 12c for escaping the ejection opening 133b of the atomizing core 13 and a second positioning surface 12b surrounding the escape opening 12c, and the cover body 12 is screwed to the housing 11 and clamps opposite ends of the atomizing core 13 between the first positioning surface 11b and the second positioning surface 12 b.

During screwing of the cover 12 onto the housing 11, the distance between the first positioning surface 11b and the second positioning surface 12b gradually decreases until the opposite ends of the atomizing core 13 are clamped against the first positioning surface 11b and the second positioning surface 12 b. Because the threaded connection can realize the continuous adjustment of the distance between the first positioning surface 11b and the second positioning surface 12b, no matter whether the length of the atomizing core 13 has an error or not, the threaded connection between the cover body 12 and the housing 11 can clamp the atomizing core 13 between the first positioning surface 11b and the second positioning surface 12b, and the gap between the two opposite ends of the atomizing core 13 and the first positioning surface 11b and the second positioning surface 12b is eliminated.

In this embodiment, the cover 12 and the housing 11 are only required to clamp the atomizing core 13, and fastening members such as screws are not required. When the cover body 12 is unscrewed, the atomizing core 13 may be directly drawn out from the opening of the first housing groove 11 a. When the assembly is needed, the atomizing core 13 is inserted into the first accommodating groove 11a from the opening, and then the cover body 12 is screwed, so that the disassembly and the assembly are convenient.

Referring to fig. 7, for example, one end of the cover 12 close to the housing 11 is formed with a threaded section, and the threaded section extends into the first receiving groove 11a from the opening and is matched with the internal thread on the inner wall of the first receiving groove 11 a.

In other embodiments, an external thread may be disposed at one end of the housing 11 close to the cover 12, an internal thread is disposed on an inner wall of the cover 12, and the cover 12 is sleeved on the circumferential outer side of the housing 11.

Illustratively, the first flow channel 2a is a gas flow channel, and the second flow channel 3a is a liquid flow channel. That is, the first flow path 2a is filled with gas, the second flow path 3a is filled with liquid, such as the dry cleaning agent, the gas flows through the venturi flow path 13a, negative pressure is generated in the venturi negative pressure suction port 133a, the liquid is sucked into the venturi flow path 13a from the venturi negative pressure suction port 133a, the gas and the liquid are mixed in the venturi flow path 13a, and mist of gas-liquid mixture is ejected from the ejection port 133b.

For example, referring to fig. 10, the groove bottom of the first receiving groove 11a has a positioning ring platform 111, the first positioning surface 11b surrounds the positioning ring platform 111, a circumferential surface of the positioning ring platform 111 and a circumferential inner wall of the first receiving groove 11a define an annular slot 11c, and referring to fig. 9, one end of the atomizing core 13 is inserted into the annular slot 11 c. It will be appreciated that the venturi channel 13a extends lengthwise through the atomizing core 13, and when the atomizing core 13 is inserted into the annular slot 11c, the outlet 2a ″ of the first channel 2a is aligned with and communicates with the inlet of the venturi channel 13 a.

Note that the groove bottom of the first accommodation groove 11a refers to a side of the first accommodation groove 11a away from the opening.

In this embodiment, the positioning ring 111 can better position the atomizing core 13, prevent the atomizing core 13 from moving in the first receiving groove 11a along any side perpendicular to the length direction of the atomizing core 13, and enable the atomizing core 13 to be accurately inserted into the correct position during the assembly process, so that the inlet of the venturi channel 13a is aligned with the outlet 2a ″ of the first channel 2a.

Referring to fig. 7, for example, the circumferential outer surface of the atomizing core 13 at the end close to the outlet 2a ″ of the first flow passage 2a is provided with an annular groove 131a, i.e., the annular groove 131a surrounds the circumferential surface of the outer portion of the atomizing core 13. Referring to fig. 7 and 9, the injection device 100 includes a sealing ring 5, and the sealing ring 5 is disposed in the annular groove 131a and is in sealing contact with the circumferential inner wall of the first receiving groove 11 a. The seal ring 5 can enhance the sealing performance between the atomizing core 13 and the circumferential inner wall of the first containing groove 11a, and reduce the possibility that the fluid in the first flow passage 2a enters the second flow passage 3a along the gap between the atomizing core 13 and the circumferential inner wall of the first containing groove 11 a.

For example, referring to fig. 7, the atomizing core 13 includes an inlet shaft segment 131, a necking shaft segment 132 and an outlet shaft segment 133 which are sequentially arranged along the fluid flow direction of the first flow channel 2a. The neck shaft segment 132 has an outer diameter that is less than the outer diameter of the inlet shaft segment 131 and less than the outer diameter of the outlet shaft segment 133. That is, the atomizing core 13 has a structure in which both ends are large and the middle is small.

The inlet shaft segment 131 is inserted into the first receiving groove 11a, and the outer surface of the inlet shaft segment 131 is in sealing engagement with the circumferential inner wall of the first receiving groove 11 a. For example, the inlet shaft segment 131 is inserted into the annular insertion groove 11c described above. The ring groove 131a is provided on the circumferential surface of the inlet shaft section 131.

The outlet shaft section 133 is inserted into the second accommodation groove 12a, the venturi negative pressure suction port 133a is provided in the outlet shaft section 133, and the outlet of the second flow passage 3a is provided on the circumferential inner wall of the first accommodation groove 11 a.

The gap between the neck shaft segment 132 and the circumferential inner wall of the mounting cavity 1a is a first gap, and the gap between the outlet shaft segment 133 and the circumferential inner wall of the second accommodation groove 12a is a second gap, wherein the first gap is larger than the second gap.

Referring to fig. 9, a region between the circumferential surface of the necking shaft segment 132 and the circumferential inner wall of the mounting cavity 1a forms a premixing zone 1b, and the outlet of the second flow channel 3a is disposed on the sidewall of the premixing zone 1b, i.e., on the sidewall of the first receiving groove 11a within the length range corresponding to the premixing zone 1 b.

The liquid from the second flow path 3a enters the premixing area 1b, flows spirally in the premixing area 1b, and is premixed with the air, so that the liquid can be more efficiently mixed with the air flow from the first flow path 2a after entering the venturi flow path 13a from the venturi negative pressure suction port 133a, and the size of the mist beads sprayed from the spray port 133b is smaller and more uniform.

The number of the venturi negative pressure suction ports 133a is not limited, and may be one or more, for example.

Illustratively, the minimum flow cross-sectional area of the region between the outlet shaft section 133 and the circumferential inner wall of the second accommodation groove 12a is smaller than the sum of the flow cross-sectional areas of the venturi negative pressure suction ports 133 a. In this way, the total flow rate entering the venturi flow passage 13a from the second flow passage 3a depends on the minimum flow cross-sectional area of the region between the outlet shaft section 133 and the circumferential inner wall of the second housing groove 12a, which can be controlled by the dimensional clearance between the outlet shaft section 133 and the second housing groove 12a, the size of the venturi negative pressure suction port 133a itself is small, and it is difficult to control the accuracy of the small size during the manufacturing process, whereas in this embodiment, it is much easier to control by the dimensional clearance between the outlet shaft section 133 and the second housing groove 12a, and thus, the manufacturing accuracy requirement and the process requirement can be reduced, and the cost can be reduced while the accuracy of the ejector 100 is secured.

Illustratively, the threaded engagement of the cover 12 and the housing 11 forms an air intake passage. That is, the screw-fitting of the cover body 12 and the housing 11 does not completely seal air-tightly, but a small amount of gas can be allowed to flow from the screw gap into the butt joint of the first receiving groove 11a and the second receiving groove 12 a.

Illustratively, the screw thread interface between the housing 11 and the cover 12 is located on the side wall corresponding to the premixing area 1b, that is, on the side wall of the mounting cavity 1a corresponding to the necking shaft segment 132. In this way, during the injection process, the external air is continuously sucked into the premixing area 1b from the thread butt joint, so that the liquid entering from the second flow passage 3a can be premixed with the air in the premixing area 1 b.

Illustratively, referring to FIG. 11, venturi flow passage 13a includes a converging section 13aa, a throat section 13ab, and a diverging section 13ac. A throat section 13ab connects the converging section 13aa and the diverging section 13ac. The venturi negative pressure suction port 133a is provided in the side wall of the divergent section 13ac corresponding to a portion close to the throat section 13 ab. In the direction from the inlet of the venturi flow passage 13a to the injection port 133b, the flow cross-sectional area of the convergent section 13aa gradually decreases, and the flow cross-sectional area of the divergent section 13ac gradually increases. The flow cross-sectional area of throat section 13ab remains substantially constant. The end of the divergent section 13ac forms the ejection port 133b.

When the gas flows in the venturi channel 13a, in the process of flowing through the convergent section 13aa, the flow cross-sectional area of the convergent section 13aa is gradually reduced, so that the flow velocity of the gas flow is gradually increased, the static pressure is gradually reduced, when the gas flow flows to the throat section 13ab, the flow velocity of the gas flow reaches the maximum, and the static pressure reaches the minimum, so that the gas flow can have a great flow velocity near the outlet of the throat section 13ab, and great suction force is generated conveniently. The venturi negative pressure suction port 133a is disposed on the side wall corresponding to the portion of the expansion section 13ac close to the throat section 13ab, so that on one hand, the airflow can generate a large suction force at the portion, and on the other hand, after being sucked into the expansion section 13ac from the venturi negative pressure suction port 133a, the dry cleaning agent can smoothly flow to the injection port 133b along the expansion section 13ac without being obstructed by the flow.

So, can obviously increase the speed and the energy that dry cleaning agent sprays to clothing surface, fast, kinetic energy is big, promotes that dry cleaning agent permeates to the clothing fibre of micron order fast, deeply in, promotes scrubbing efficiency.

Illustratively, the venturi channel 13a corresponding to the length of the outlet shaft segment 133 is composed of the converging section 13aa, the throat section 13ab, and the diverging section 13ac.
