[0090] As an embodiment of the present application, the sub-guide unit 202 is horizontally arranged in the pressure mixing chamber 102 at a position corresponding to the first nozzle 104, and a distance is provided between the first end of the sub-guide unit 202 and the first nozzle 104, and the last end of the sub-guide unit 202 is connected to the first end of the limiting unit 201;

[0092] As an embodiment of the present application, as shown in Figure 7 the first channel 2011 penetrating the limiting unit 201 in the horizontal direction is arranged at a position corresponding to the first nozzle 104 in the limiting unit 201; in this embodiment, as shown in Figure 4 the connecting piece in communication with the first channel 2011 is extended at a position corresponding to the limiting unit 201 at the first end of the limiting unit 201, and the sub-guide unit 202 is connected to the connecting piece by direct insertion or threaded connection, thereby achieving the communication between the sub-guide unit 202 and the first end of the first channel 2011; the second channel 2012 penetrating the limiting unit 201 in the horizontal direction is arranged at a position corresponding to the second nozzle 204 in the limiting unit 201;

[0093] As an embodiment of the present application, the first channel 2011 and the second channel 2012 are respectively the guide flow channels for gas medium and liquid medium; specifically, in this embodiment, the sub-guide unit 202 comprises: a guide nozzle 2021, the input end of the guide nozzle 2021 is connected to the first end of the first channel 2011, Figure 4 in which the right end of the guide nozzle 2021 is the input end of the guide nozzle 2021; the guide nozzle 2021 and the first end of the first channel 2011 constitute the collecting and output channel; Figure 7 in which the left side of the first channel 2011 is the first end of the first channel 2011; Figure 8In the figure, the dotted arrow and the solid arrow represent the flow direction of two different fluid media in the device respectively;

[0094] As an embodiment of the present application, the fluid collection unit 203 comprises at least two flow guide pipes 2031, and it is conceivable that if the adapted cleaning product requires multiple inputs of the to-be-sprayed medium, multiple flow guide pipes 2031 and multiple second channels 2012 can be provided to meet the different medium input requirements;

[0095] As an embodiment of the present application, the two flow guide pipes 2031 are soft pipe joints, which are convenient for installation and insertion; the two flow guide pipes 2031 are respectively connected to the first channel 2011 and the second channel 2012 at the end of the limiting unit 201;

[0096] As an embodiment of the present application, the connection mode between the two flow guide pipes 2031 and the first channel 2011 and the second channel 2012 is direct insertion, or the first channel 2011 and the second channel 2012 are provided with threads, and the two flow guide pipes 2031 are threadedly connected; the two flow guide pipes 2031 are respectively connected to the end of the first channel 2011 and the end of the second channel 2012 to form two collection input channels;

[0097] As an embodiment of the present application, the length of the fluid channel formed by the flow guide nozzle 2021, the first channel 2011 and one flow guide pipe 2031 is greater than the length of the fluid channel formed by the second channel 2012 and the other flow guide pipe 2031; in this embodiment, the two flow guide pipes 2031 are parallel to each other, and the first channel 2011 and the second channel 2012 are parallel to each other, but correspondingly, the parallel relationship between the two flow guide pipes 2031, the first channel 2011 and the second channel 2012 needs to be set according to the specific situation, and is not limited to the above relationship;

[0098] As an embodiment of the present application, based on the structure design of each component in the above embodiment, when different forms of gas-liquid mixture spraying need to be realized by using the device, only the nozzle unit 101 with a different first nozzle 104 design needs to be replaced, so in this embodiment, the shape of the first nozzle 104 includes an oval shape and a circular shape, the gas-liquid mixture output by the oval-shaped first nozzle 104 is oval-shaped, and the gas-liquid mixture output by the circular-shaped first nozzle 104 is circular-shaped, and it is conceivable that the shape of the first nozzle 104 includes but is not limited to the above two shapes, and can be set according to specific needs;

[0099] As one embodiment of the present invention, in addition to achieving different forms of gas-liquid mixture injection through the shape design of the first nozzle 104, different forms of gas-liquid mixture injection can also be achieved through the design of the nozzle depth and nozzle length of the first nozzle 104. When achieving different forms of gas-liquid mixture injection, different degrees of gas-liquid mixing can also be achieved to meet the needs of different scenarios. Figure 3 The first nozzle 104 shown is an example. Figure 3 The length from the upper end to the lower end of the first nozzle 104 is the nozzle length of the first nozzle 104. Figure 3 The length between the edge of the first nozzle 104 at the top of the nozzle unit 101 and the edge of the first nozzle 104 near the pressure mixing chamber 102 inside the nozzle unit 101 is the nozzle depth of the first nozzle 104; therefore, the nozzle specifications of the first nozzle 104 include: nozzle length and nozzle depth; the specification parameters of the nozzle specifications of the first nozzle 104 include, but are not limited to: first specification parameter and second specification parameter. The first specification parameter is different from the second specification parameter. The first specification parameter and the second specification parameter are only used for illustration. The nozzle specifications of the first nozzle 104 are variable in design.

[0100] As one embodiment of the present invention, such as Figure 9 and Figure 10 As shown, Figure 9 and Figure 10 In this diagram, D represents the nozzle depth and L represents the nozzle width, both in millimeters (mm). Through simulation design and testing of four different schemes, the spraying state of the device under different nozzle depths and lengths was examined. Figure 9 The results show that when the nozzle length of the first nozzle 104 is constant, the smaller its nozzle depth, the better the fluid mixing; when the nozzle depth of the first nozzle 104 is constant, the smaller its nozzle length, the better the fluid mixing and the larger the spray range; according to Figure 10 The results show that when the length of the first nozzle 104 is constant, the smaller the nozzle depth, the greater the ellipticity of the gas-liquid mixture ejected by the first nozzle 104, the better the fluid mixing, and the larger the spray range; when the length of the first nozzle 104 is constant, the greater the nozzle depth, the smaller the ellipticity of the gas-liquid mixture ejected by the first nozzle 104, the worse the fluid mixing, and the smaller the spray range. Therefore, the nozzle specifications of the first nozzle 104 in this device can be designed according to this principle to meet the needs of different application scenarios.

[0101] Specifically, the working principle of this invention is as follows:

[0102] According to the structural positional relationship described above, after combining the various components of this device, it is used in cleaning products. During use:

[0103] The two fluid media continuously discharged by the cleaning product will enter the first channel 2011 and the second channel 2012 through the two guide tubes 2031 respectively.

[0104] After that, as Figure 7 As shown, since the lengths of the fluid channels corresponding to the first channel 2011 and the second channel 2012 are different, and the shapes of the two fluid channels are also different due to the design of the conical chamber inside the nozzle unit 101, the flow velocities of the two fluid media inside the nozzle unit 101 are different. Therefore, the two fluid media will generate a pressure difference at the position near the first nozzle 104 in the nozzle unit 101, so that the two fluid media will be fully mixed before being ejected from the first nozzle 104.

[0111] As one embodiment of the present invention, such as Figure 11The diagram illustrates a connection method between a pipeline module 301, a power source module 302, a supply source module 303, and the flow guiding device: one end of the second pipeline 3012 is connected to the collecting input channel corresponding to the first nozzle 104, and the other end of the second pipeline 3012 extends downward at an angle, and after the angled extension, is horizontally connected to the output end of the power source module 302; one end of the first pipeline 3011 is connected to the collecting input channel corresponding to the second nozzle 204, and the other end of the first pipeline 3011 extends downward at an angle... The first pipe 3011 extends vertically downwards after an inclined extension and connects to the inside of the supply source module 303. One end of the first pipe 3011 connecting to the inside of the supply source module 303 is positioned near the bottom of the supply source module 303. Correspondingly, based on the above embodiment, when the other end of the second pipe 3012 is horizontally connected to the output end of the power source module 302, an air intake valve 3032 is provided at the top of the supply source module 303 to ensure normal operation between the modules. Correspondingly, when this injection control device is used, if... Figure 13 As shown, Figure 13 The dashed arrow indicates the direction of gas flow, and the solid arrow indicates the direction of liquid flow; therefore, combining... Figure 13 As shown, in Figure 11 In the illustrated embodiment, the first nozzle 104 is a gas output nozzle, and the second nozzle 204 is a liquid output nozzle. The specific working principle is as follows: The gas injected by the power source module 302 (i.e., the air pump) directly reaches the pressure mixing chamber 102 inside the flow guide device through the second pipeline 3012 and the first channel 2011 between the flow guide device. In this structure, because the gas flow path is smooth and short, the gas velocity is relatively high, resulting in low pressure at the nozzle unit 101. According to Bernoulli's principle, the liquid to be mixed 3031 in the water tank, supplied by the power source module 303, is drawn through the first pipeline 3011 by external atmospheric pressure to the pressure mixing chamber 102 inside the flow guide device, thereby fully mixing the slow-flowing liquid with the fast-flowing gas and ejecting it. In this embodiment, the air inlet valve 3032 is one-way open to balance the pressure inside the water tank. This injection control device design simplifies the pipeline structure and reduces production costs.

[0112] As one embodiment of the present invention, such as Figure 12As shown, another connection method between the pipeline module 301, power source module 302, supply source module 303, and the flow guiding device is illustrated: one end of the first pipeline 3011 is connected to the collecting input channel corresponding to the first nozzle 104, and the other end of the first pipeline 3011 extends downward at an angle, and after the angled extension, extends vertically downward and connects to the interior of the supply source module 303 near the bottom of the supply source module 303; one end of the second pipeline 3012 is connected to the collecting input channel corresponding to the second nozzle 204, and the other end of the second pipeline 3012 extends upward at an angle, and after the angled extension, extends vertically downward and connects to the interior of the supply source module 303 near the top of the supply source module 303; the vertical section of the second pipeline 3012 corresponding to the position of the power source module 302 is connected to the output end of the power source module 302 via a connecting member 3013; in this embodiment, the connecting member 3013 is a tee; as Figure 12 and Figure 13 As shown, Figure 12 Implementation methods and Figure 11 The implementation methods differ significantly in that they are in Figure 12 In this embodiment, the second gas-guiding pipe 3012 is connected to the second nozzle 204, and the first liquid-guiding pipe 3011 is connected to the first nozzle 104. This makes the first nozzle 104 a liquid output nozzle and the second nozzle 204 a gas output nozzle. Figure 13 As shown, in Figure 12 In the illustrated embodiment, the working principle is as follows: The gas ejected from the power source module 302, i.e., the air pump, is divided into two paths through a three-way valve. One path of gas directly reaches the nozzle unit 101 of the flow guiding device through the second nozzle 204; the other path of gas enters the water tank, forcing the liquid in the tank out and flowing along the first pipe 3011 to the first nozzle 104, and finally reaching the nozzle unit 101. The liquid and gas are fully mixed in front of the pressure mixing chamber 102 in the nozzle unit 101 and then ejected, realizing the gas-liquid mixture injection. When using this embodiment, it is necessary to ensure the sealing of the first pipe 3011 and the second pipe 3012. In this embodiment 2, including but not limited to the above... Figure 11 as well as Figure 12 The two implementation methods are shown.
