Alternatively, the cartridge assembly 10 includes a seal ring 11 and a rotatable inner cartridge, the seal ring 11 and the inner cartridge being coaxially disposed, and the seal ring 11 and the inner cartridge surrounding to form the accommodation chamber 101.

The following will focus on the description of the structure of the head 20. As shown in fig. 4 to 6, fig. 4 schematically illustrates a schematic structural view of the spray head 20 according to an embodiment of the present utility model, and fig. 5 is a schematic structural view of the spray head 20 illustrated in fig. 4 at a second viewing angle; fig. 6 is a sectional view in the direction C-C of fig. 5. The nozzle 20 includes an inlet port 22, a tube body 21, an outlet port 23, and an inlet port 25, the outlet port 23 and the inlet port 22 communicating with a lumen 24 of the tube body 21, respectively; the air inlet 25 is provided in the pipe body 21 and communicates with the pipe chamber 24, and the air inlet 25 and the air outlet 23 are offset from each other along the circumferential direction of the pipe body 21.

In general, the air inlet 25 and the air outlet 23 are located on the same side of the tube 21 and are spaced along the axial direction of the tube 21, so that the detergent solution sprayed from the air outlet 23 easily enters the tube cavity 24 of the tube 21 from the position of the air inlet 25, and the amount of foam sprayed on the clothes is reduced.

According to the spray head 20 of the present utility model, by arranging the air inlet 25 and the air outlet 23 so as to be offset along the circumferential direction of the pipe body 21, the distance between the air outlet 23 and the air inlet 25 can be increased, so that the detergent solution is not easy to enter the air inlet 25 when discharged from the air outlet 23 after entering the pipe body 21 from the inlet 22, and the amount of foam sprayed on clothes is increased.

Here, the air inlet 25 and the air outlet 23 are offset from each other in the circumferential direction of the pipe 21, that is, the projection of the air inlet 25 toward the air outlet 23 in the extending direction of the pipe 21 does not overlap with the air outlet 23, and the air inlet 25 and the air outlet 23 are located at different positions in the radial direction of the pipe 21.

Optionally, the air inlet 25 is a circular hole, and the diameter of the air inlet 25 is in a range of 2 to 3.6 mm, such as 3 mm or 2.5 mm, so that on one hand, the air intake amount can be ensured, and on the other hand, the probability of liquid entering the lumen 24 from the position of the air inlet 25 can be reduced.

Optionally, the air inlet 25 is disposed on a side wall of the pipe body 21, the outlet 23 is disposed at one end of the pipe body 21, the inlet 22 is disposed at the other end of the pipe body 21, and a first included angle β is formed between the air inlet 25 and the outlet 23, and the range of the first included angle β is greater than or equal to 90 degrees and less than or equal to 180 degrees. Here, by defining the first angle β between the intake port 25 and the exhaust port 23, when the first angle β is an obtuse angle, the orientations of the intake port 25 and the exhaust port 23 can be reversed such that the distance between the exhaust port 23 and the intake port 25 is long. The first included angle β may be 120 degrees or 135 degrees, which may make the distance between the discharge port 23 and the air inlet 25 in the circumferential direction of the tube 21 longer, so as to reduce the probability of the cleaning agent solution entering the lumen 24 from the air inlet 25.

Alternatively, the height of the air inlet 25 and the discharge 23 in the axial direction of the tube 21 is different. Wherein the air inlet 25 is provided closer to the inlet port 22 in the flow direction of the fluid, and the height of the air inlet 25 is different from the height of the outlet port 23 in the axial direction of the tube body 21, wherein the height of the air inlet 25 is higher than the height of the outlet port 23. Here, by making the heights of the air inlet 25 and the air outlet 23 along the axial direction of the pipe body 21 different, the heights of the air inlet 25 and the air outlet 23 along the pipe body 21 can be made different, and the distance between the air inlet 25 and the air outlet 23 in the axial direction of the pipe body 21 can be increased, so that the distance between the air inlet 25 and the air outlet 23 can be increased, and the probability of the detergent solution entering the pipe cavity 24 from the air inlet 25 can be reduced.

It is to be understood that the heights of the air inlet 25 and the air outlet 23 along the axial direction of the pipe body 21 may be the same, and in this case, the air inlet 25 and the air outlet 23 are provided at both ends of the pipe body 21 in the radial direction, respectively. Considering that the diameter sizes of the air inlet 25 and the exhaust 23 may be non-uniform, the axis of the air inlet 25 and the axis of the exhaust 23 may be selected as a reference for comparison.

The structure of the pipe body 21 will be described with emphasis.

Alternatively, the tube 21 is a venturi structure. And the pipe body 21 comprises at least two mutually communicated pipe sections, and the air inlet 25 and the air outlet 23 are respectively arranged on different pipe sections. The venturi tube generally comprises an inlet section, a constriction section, a throat section and a diffuser section, where the inlet 25 and the outlet 23 are provided on separate tube sections, respectively, whereby the inlet 25 is used for the inlet and the outlet 23 is used for the outlet of the foam.

In some embodiments, the at least two interconnected tube segments comprise a first tube segment 241, a second tube segment 242, and a third tube segment 243 in sequential communication, wherein the exhaust port 23 is disposed at an end of the third tube segment 243; the air inlet 25 is disposed in the second tube segment 242 and communicates with the lumen 24. The first pipe section 241 is a constriction section of the venturi tube, the second pipe section 242 is a throat of the venturi tube, the third pipe section 243 is a diffusion section of the venturi tube, and the air inlet 25 is disposed on the second pipe section 242 to realize air intake. The interior of the tube section is a lumen 24.

The inner diameter of the second pipe section 242 is smaller than that of the first pipe section 241, and the inner diameter of the second pipe section 242 is smaller than that of the third pipe section 243, and the side wall of the second pipe section 242 is provided with the air inlet 25. Since the second tube section 242 is the narrowest section of the tube body 21, a negative pressure is created within the second tube section 242 and the air inlet 25 is configured such that air can be drawn into the lumen 24 by the negative pressure to mix with the water flow within the tube body 21 to create foam. The tube 21 is a venturi tube, and in use, when the spray head 20 is used for spraying the detergent solution, the detergent solution is mixed with air to generate more foam, so that the washing effect of the laundry treating apparatus 100 is better.

In some embodiments, at least two interconnected pipe segments further comprise a fourth pipe segment 244. The fourth pipe section 244 is arranged above the third pipe section 243, that is to say the fourth pipe section 244 is arranged on the side of the third pipe section 243 remote from the second pipe section 242. Within the fourth pipe section 244, a turbulence structure 245 is provided, the turbulence structure 245 providing a velocity division of the fluid in the lumen 24 flowing through the turbulence structure 245 in the circumferential direction of the lumen 24. The turbulence structures 245 may break up the fluid flowing through the turbulence structures 245 to form fine particles and then spray the fine particles through the discharge port 23, so that the washing effect of the laundry treating apparatus 100 is better.

In some embodiments, the internal flow passage of the first tube segment 241 is of a tapered configuration with the small rounded end of the tapered configuration communicating with the second tube segment 242; the tapered configuration enables a negative pressure to be created within the tube 21 after the fluid is ejected from the outlet 23. That is, the internal flow channel of the first pipe section 241 has an inverted cone structure, so that the fluid is ejected from the outlet 23 to generate negative pressure in the pipe body 21, thereby facilitating air entering from the position of the air inlet 25.

In some embodiments, the first tube segment 241 is a conical converging segment, the second tube segment 242 is a cylindrical throat segment, the third tube segment 243 is a conical diverging segment, and the fourth tube segment 244 is an inlet cylindrical segment. This structure is a typical venturi structure where the structure of each segment is not expanded.

In some embodiments, as shown in fig. 7 and 8, fig. 7 is a schematic perspective view of the third pipe section 243 of the sprinkler head 20 shown in fig. 5, and fig. 8 is a schematic perspective view of the third pipe section of the sprinkler head shown in fig. 5 at a second viewing angle. The tube 21 further comprises a communication chamber 29. The communication chamber 29 is provided in the second pipe section 242. The air inlet 25 communicates with the lumen 24 through a communication chamber 29. Thus, under the action of the negative pressure, air can enter the air inlet 25 and the communication cavity 29 in sequence, and then enter the pipe cavity 24. At least one bending structure 293 is provided in the communication chamber 29, which prevents the fluid in the receiving chamber 101 from flowing back from the communication chamber 29 to the air inlet 25 and into the lumen 24 during use of the laundry treating apparatus 100.

In some embodiments, as shown in fig. 7 and 8, the communication cavity 29 includes a first communication portion 291 and a second communication portion 292. The first and second communication portions 291 and 292 constitute the communication chamber 29, and the first and second communication portions 291 and 292 may be provided by providing a bent structure 293 in the communication chamber 29. The inner cavity of the second pipe section 242, the first communication portion 291, the second communication portion 292, and the air inlet 25 are sequentially communicated, wherein the size of the first communication portion 291 is smaller than the size of the second communication portion 292 and smaller than the size of the air inlet 25 and smaller than the size of the second pipe section 242, respectively, along the axial direction of the second pipe section 242. The first communicating portion 291 is directly communicated with the second pipe section 242, the axial dimension of the first communicating portion 291 is minimum, fluid in the second pipe section 242 can be guaranteed not to flow backwards into the first communicating portion 291 easily, and further the fluid cannot flow backwards into the second communicating portion 292 and the air inlet 25, and water leakage from the outer side of the air inlet 25 is avoided.

In some embodiments, the tube 21 is a common straight tube, the air inlet 25 may be formed in the middle of the tube 21, and then the air is pumped into the tube cavity 24 through the air inlet 25 by an additional pumping device, so that more foam can be generated by mixing with the washing water of the tube 21, and the washing effect of the laundry treatment apparatus 100 is better.

Alternatively, the air inlet 25 is provided on the side wall of the second pipe section 242, and the air inlet 25 is provided at a connection position of the second pipe section 242 and the first pipe section 241, that is, the air inlet 25 may be provided at a position of the first pipe section 241 adjacent to the second pipe section 242, or the air inlet 25 may be provided at a position of the second pipe section 242 adjacent to the first pipe section 241.

By providing the gas inlet 25 at the outflow end of the first pipe section 241 or the inflow end of the second pipe section 242, the tapered structure can be utilized sufficiently to generate negative pressure in the pipe body 21 after the fluid is ejected from the outlet 23, thereby increasing the amount of gas entering from the gas inlet 25.

In some embodiments, as shown in fig. 6, the angle between the axis of the second tube segment 242 and the axis of the exhaust port 23 is a second angle phi that is greater than 90 degrees and less than or equal to 180 degrees. The second pipe section 242 is a vertical pipe section, the third pipe section 243 is an arc pipe, and the second included angle phi is greater than 90 degrees and less than or equal to 180 degrees, such as 135 degrees or 145 degrees, so that the flow of the cleaning agent solution is smoother, the resistance in the flowing process is reduced, and the cleaning agent solution is quickly sprayed into the accommodating cavity 101.

Referring to fig. 4, a first protrusion 26 and a second protrusion 27 are provided on the outer peripheral surface of the tube 21 at intervals. A first protrusion 26 and a second protrusion 27. The first protrusion 26 and the second protrusion 27 play a limiting role, and prevent the pipe body 21 from moving up and down along the axial direction of the pipe body 21, so that the pipe body 21 is kept fixed. It will be appreciated that the first projection 26 and the second projection 27 are both located above the air inlet 25, i.e. the first projection 26 and the second projection 27 are both located on the side of the air inlet 25 remote from the outlet 23, the air inlet 25 being located inside the receiving chamber 101.

That is, the first protrusion 26 and the second protrusion 27 are both located above the air inlet 25, and the discharge port 23 is flush with the air inlet 25 or lower than the air inlet 25.

Referring to fig. 4, a third protrusion 28 is further disposed on the outer peripheral surface of the tube 21, and the third protrusion 28 is disposed near the inlet 22. In use, the tube 21 is inserted into the delivery tube 30, and the third protrusion 28 may cause the tube 21 to have an interference fit with the delivery tube 30, thereby firmly connecting the tube 21 with the delivery tube 30.

In some embodiments, the third protrusion 28 is annular and fits over the outer circumference of the tube 21. And the third projection 28 extends from the end of the outer peripheral surface of the tube body 21 where the inlet port 22 is located toward the outlet port 23 by a certain distance. This facilitates a certain mating distance between the third protrusion 28 and the delivery tube 30, so that the interference fit between the third protrusion 28 and the delivery tube 30 is relatively strong. Further, the outer diameter of the third protrusion 28 gradually increases from the inlet port 22 to the outlet port 23, which may allow the third protrusion 28 to have a guiding effect for facilitating insertion of the tube body 21 into the interior of the delivery tube 30 during use.

In some embodiments, the first boss 26, the second boss 27, and the third boss 28 are integrally formed with the tube body 21. The integral structure can simplify the manufacturing process of the spray head 20, and the spray head 20 can be manufactured by an integral molding process in an injection molding or casting mode. Accordingly, the material of the nozzle 20 may be metal or plastic, and may be manufactured by an integral molding process.

The structure of other parts in the present utility model is referred to the prior art, and the description of the present utility model is omitted herein.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
