Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A dispensing assembly for dispensing lotion according to an embodiment of the present invention is described below with reference to fig. 1-3.
A dispensing assembly for dispensing a lotion according to an embodiment of the first aspect of the present invention comprises: a main vessel shell 1 and an injection tube 3.
Referring to fig. 1, the main pipe casing 1 includes a liquid inlet section 11, a mixing section 12 and a liquid outlet section 13 connected in sequence, a suction port 101 and a gas inlet 102 are formed on a side wall of the main pipe casing 1, gas such as air can enter the main pipe casing 1 through the gas inlet 102, and lotion is adapted to flow into the main pipe casing 1 through the suction port 101.
Alternatively, the suction port 101 and the air inlet 102 may be different ports independent of each other, the suction port 101 and the air inlet 102 being formed at different positions of the main tubular housing 1; the suction port 101 and the gas inlet port 102 may share one port through which both the wash solution and the external gas may enter the main tubular housing 1, and the wash solution and the external gas may alternately enter the main tubular housing 1 through the shared port.
The injection pipe 3 is disposed on the main casing 1 and located on the upstream side of the mixing section 12 (the "injection pipe 3 is located on the upstream side of the mixing section 12" means that the entire injection pipe 3 is located on the upstream side of the mixing section 12, the upstream is with respect to the flow direction of the water flow), at least a part of the injection pipe 3 is disposed in the liquid inlet section 11, for example, the entire injection pipe 3 may be located in the liquid inlet section 11, or a part of the injection pipe 3 may be located in the liquid inlet pipe, another part of the injection pipe 3 is located outside the liquid inlet section 11 and outside the main casing 1, and the inlet end of the injection pipe 3 may be connected to the water inlet valve of the washing machine through a connection hose. The portion of the injection pipe 3 adjacent to the mixing section 12 is formed as an injection section 32, and water is adapted to be injected into the mixing section 12 through the injection section 32 of the injection pipe 3, so that external air is sucked into the main tubular housing 1 through the air inlet 102 using negative pressure generated by water flow in the mixing section 12 as a driving force.
Wherein, can utilize the negative pressure that the rivers produced in mixing section 12 as the driving force for lotion is inhaled through suction inlet 101 to be in being responsible for the shell 1, also can utilize pump etc. as power, make lotion be inhaled through suction inlet 101 to be responsible for in the shell 1 through the suction action of pump. Alternatively, the negative pressure generated by the water flow in the mixing section 12 and the suction action of the pump may be used simultaneously to suck the lotion into the main pipe housing 1 through the suction port 101.
Therefore, when the putting assembly is used for the putting device of the washing machine, the putting device can put the washing agent into the washing barrel of the washing machine. In the process of putting the lotion by using the putting component, water flow flows into the injection pipe 3 and forms high-speed water flow to be injected into the mixing section 12 after being pressurized and accelerated by the injection section 32 of the injection pipe 3, the lotion sucked by the suction port 101 and the gas sucked by the gas inlet 102 also enter the main pipe shell 1, and the gas, the water and the lotion are mixed in the mixing section 12 of the main pipe shell 1, so that the lotion is fully mixed, dissolved and foamed, and the lotion flows into a washing barrel of the washing machine through the liquid outlet section 13 after being fully mixed, dissolved and foamed. Therefore, after the lotion enters the main pipe shell 1, the lotion is dissolved in the water flow in the main pipe shell 1, and at the same time, because the air enters the main pipe shell 1, the dissolution of the lotion can be promoted through the sufficient mixing of the air, the water and the lotion, for example, when the lotion is a detergent, the foaming effect of the lotion can be improved, the foam after foaming is more fine, and the cleaning effect is improved.
The lotion comprises detergent, softener, disinfectant and the like, namely the lotion generally refers to additives for putting in a laundry process. When the washing machine is in a washing stage, the detergent can enter the main pipe shell 1 through the suction inlet 101, and the gas can enter the main pipe shell 1 through the gas inlet 102, so that the detergent can be fully dissolved, the foaming effect of the detergent is improved, and the cleaning effect is improved; when the washing machine is in a rinsing stage, the softener and the disinfectant can enter the main pipe shell 1 through the suction inlet 101, and the gas can enter the main pipe shell 1 through the gas inlet 102, so that the softener and the disinfectant can be fully dissolved, the hand feeling is improved, and the disinfection rate is improved. After the washing and rinsing phases of the washing machine, a water flow may be sucked through the suction port 101 to flush the suction port 101 after the corresponding detergent is put in.
Because the dispensing assembly can fully dissolve the lotion in water, the lotion can play a more sufficient role in the washing process, for example, the cleaning effect can be improved, the hand feeling can be improved, and the disinfection rate can be improved.
Alternatively, when the suction port 101 and the air inlet port 102 are different ports independent from each other, the air inlet port 102 and the suction port 101 may be disposed adjacent to each other, and by disposing the air inlet port 102 and the suction port 101 adjacent to each other, lotion and air can be contacted and sufficiently mixed in a short time after entering the main casing 1, so that the dissolving effect and the foaming effect of the lotion can be further improved.
In addition, when suction inlet 101 and air inlet 102 are the different mouths that are independent from each other, because gas is in being responsible for the shell 1 through air inlet 102 entering, lotion is in being responsible for the shell 1 through suction inlet 101 entering, and air inlet 102 and suction inlet 101 are independent from each other, lotion and gas are in entering main shell 1 by independent passageway separately for the letting in of lotion and gas is not influenced mutually, make under the condition that does not wash, can not influence gaseous letting in because of the caking coagulation of lotion under the influence of air, reduce the jam risk of gas circuit.
Wherein the inner diameter of the mixing section 12 is d1, the inner diameter of the jetting section 32 is d2, and the value range of d1/d2 is 1.44-2.1. If the ratio d1/d2 is too small, the high-speed water flow sprayed from the spraying section 32 of the spraying pipe 3 is subjected to a large resistance after being sprayed into the mixing section 12, which is not beneficial to generating the negative pressure at the air inlet 102; if the ratio d1/d2 is too large, after the high-speed water flow ejected from the ejection section 32 of the ejection pipe 3 is ejected into the mixing section 12, because the space in the mixing section 12 is too large relative to the space in the ejection section 32, the high-speed water flow ejected into the mixing section 12 has a small influence on the space disturbance in the mixing section 12, so that the negative pressure formed at the air inlet 102 is also small, which is not favorable for increasing the air intake.
According to the invention, by optimizing the inner diameter d1 of the mixing section 12 and the inner diameter of the injection section 32d2, the value range of d1/d2 is set between 1.44 and 2.1, so that the resistance of the high-speed water flow injected from the injection section 32 of the injection pipe 3 after being injected into the mixing section 12 is small, the negative pressure at the air inlet 102 is favorably generated, the space in the mixing section 12 is not too large relative to the space in the injection section 32, the high-speed water flow injected into the mixing section 12 is not subjected to small resistance, and the rest space near the water flow in the mixing section 12 is reasonably arranged, so that the high-speed water flow injected into the mixing section 12 has a large influence on the space disturbance in the mixing section 12, the negative pressure formed at the air inlet 102 is also large, and the suction quantity of gas is favorably improved.
Table 1 below shows the pressure at the inlet 102 for testing the internal diameters d1 of the various mixing sections 12 and d2 of the injection section 32.
TABLE 1-testing of inlet 102 pressure for different mixing section 12 inside diameters d1, and injection section 32 inside diameters d2
By analyzing the above table 1 in combination with fig. 2 (fig. 2 is a graph of pressure change at the inlet port 102 at different d1/d2 ratios when the inner diameter d2 of the injection section 32 is 3mm, wherein the horizontal axis is the ratio of d1/d2, the vertical axis is the pressure value generated at the inlet port 102, the negative pressure is a negative value, and the positive pressure is a positive value), in the test data of fig. 2: when d1/d2 is 1.15, the negative pressure at the air inlet 102 is zero, that is, no negative pressure is generated at the air inlet 102, and external air cannot enter the main pipe shell 1 through the air inlet 102 because no negative pressure is used as a driving force; when d1/d2 < 1.15, positive pressure is generated at the air inlet 102, and the water injected into the mixing section 12 may flow back to the air inlet 102; also, when d1/d2 < 1.15 and decreases, the positive pressure generated at the inlet 102 also increases. When d1/d2 is more than 1.15, negative pressure is generated at the air inlet 102, and under the premise that d1/d2 is more than 1.15, the negative pressure generated at the air inlet 102 is increased and then reduced along with the increase of the ratio of d1/d 2. The ratio of d1/d2 has a preferred range that allows for a greater negative pressure at the inlet 102.
When the value range of d1/d2 is set between 1.44 and 2.1, negative pressure is generated at the air inlet 102 and the generated negative pressure is larger, which is beneficial for the gas to enter the main pipe shell 1 from the air inlet 102, so that the amount of the gas entering the air inlet 102 is larger, the larger the negative pressure at the air inlet 102 is, the more the amount of the gas entering the mixing section 12 of the main pipe shell 1 is, the better the turbulent flow effect of the water flow sprayed into the mixing section 12 through the spraying section 32 of the spraying pipe 3 is, therefore, the mixing effect is good, the dissolving effect and the foaming effect of the lotion can be better improved, and the cleaning effect is improved.
Because can be so that the negative pressure that rivers in the mixing section 12 produced is great, the inspiratory gas volume of air inlet 102 is more, and lotion mixes the dissolution with rivers intensive mixing in mixing section 12, and the foaming effect is better, and the washing effect is better and the lotion utilization ratio is higher, also can reduce the caking risk of remaining lotion to can reduce the jam risk of pipeline.
According to the dispensing assembly for dispensing the lotion of the embodiment of the invention, the accelerated water flow is sprayed into the mixing section 12 of the main shell pipe through the arranged spraying pipe 3, and the negative pressure is generated by the water flow in the mixing section 12, external air can be sucked into the main tubular housing 1 through the suction port 101, the detergent entering from the suction port 101 and the air entering from the air inlet 102 can be mixed and foamed in the mixing section 12, by optimizing the inner diameter d1 of the mixing section 12 and the inner diameter of the spraying section 32d2, the value range of d1/d2 is set between 1.44 and 2.1, can be so that air inlet 102 department produces great negative pressure, the inspiratory gas quantity of air inlet 102 is more, and lotion mixes the dissolution with rivers intensive mixing in mixing section 12, and the foaming effect is better, and the washing effect is better and the lotion utilization ratio is higher, also can reduce the caking risk of remaining lotion to can reduce the jam risk of pipeline.
According to some embodiments of the invention, d1/d2 has a value in the range of 1.65-1.69. Therefore, the value range of d1/d2 is further optimized, negative pressure can be generated at the air inlet 102 and generated negative pressure is larger, the gas can enter the main pipe shell 1 from the air inlet 102 more conveniently, the gas quantity entering the air inlet 102 is larger, the turbulent flow effect of water flow sprayed into the mixing section 12 through the spraying section 32 of the spraying pipe 3 is better, the mixing effect is better, the dissolving effect and the foaming effect of a lotion can be better improved, and the cleaning effect is improved. For example, d1/d2 is 1.67, which is the optimum ratio for best mixing, dissolving and foaming.
With reference to table 1 and fig. 2, when the value of d1/d2 is in the range of 1.65-1.69, the negative pressure generated by the air inlet 102 can reach 200Pa basically, and when the value of d2 is small, the negative pressure generated by the air inlet 102 can reach more than 400 Pa.
According to some embodiments of the present invention, referring to fig. 1 and 2, the inner diameter d2 of the jet section 32 is no greater than 3.5 mm. Under the condition that the ratio d1/d2 is constant, the smaller the inner diameter of the injection section 32 of the injection pipe 3 is, the greater the speed of the water flow accelerated by the injection section 32 is, so that the water flow injected into the mixing section 12 through the injection section 32 has a greater influence on the air disturbance in the mixing section 12, and the more beneficial the generation of the negative pressure at the air inlet 102 and the greater the generated negative pressure are. Through the setting that is not more than 3.5mm with the internal diameter d2 of injection section 32 for the internal diameter d2 of injection section 32 sets up less, guarantees that the negative pressure that air inlet 102 department produced is great, thereby makes air inlet 102 department get into to the gas volume in the mixing channel more, further guarantees and promotes mixing, dissolving and foaming effect.
According to some embodiments of the invention, the minimum limit value of the internal diameter d2 of the injection section 32 is determined according to the pressure resistance limit of the connection hose connected to the injection pipe 3. With reference to fig. 3 (fig. 3 is a graph of the pressure change at the inlet end of the injection tube 3 under the condition of the inner diameter d2 of the different injection sections 32, where the vertical axis is the pressure at the inlet end of the injection tube 3, when d1/d2 is 1.67), the smaller the inner diameter d2 of the injection section 32, the larger the pressure at the inlet end of the injection tube 3.
Under the condition that the ratio d1/d2 is constant, the smaller the inner diameter of the injection section 32 of the injection pipe 3 is, the greater the speed of the water flow accelerated by the injection section 32 is, so that the water flow injected into the mixing section 12 through the injection section 32 has a greater influence on the air disturbance in the mixing section 12, and the more beneficial the generation of the negative pressure at the air inlet 102 and the greater the generated negative pressure are. In view of the limited pressure-bearing capacity of the connection hose connected to the ejector tube 3, in order to prevent the connection hose connected to the ejector tube 3 from bursting due to excessive water pressure, the minimum limit value of the inner diameter d2 of the ejector stage 32 is determined in accordance with the pressure-resistant limit value of the connection hose connected to the ejector tube 3 so that the inner diameter d2 of the ejector stage 32 is not greater than the minimum limit value, and the connection hose connected to the ejector tube 3 can be prevented from bursting due to excessive water pressure while allowing as much negative pressure to be generated at the air inlet 102 as possible.
According to some embodiments of the present invention, referring to fig. 1, the intake 102 is formed at the intake section 11, and the intake 101 is formed at the intake section 11 or the mixing section 12. Therefore, the air inlet 102 is formed in the liquid inlet section 11, so that negative pressure generated by water flow in the mixing section 12 can be better utilized as driving force, and external air is sucked into the main pipe shell 1 through the air inlet 102; in addition, the suction port 101 is formed in the liquid inlet section 11 or the mixing section 12, so that the lotion and the gas can be conveniently and fully mixed in the mixing section 12, and the dissolving and foaming effects are improved.
In some alternative embodiments of the invention, referring to fig. 1, a flow space 301 is defined between the outer side wall of the injection pipe 3 and the inner side wall of the liquid inlet section 11, the flow space 301 communicating with the mixing section 12. When the air inlet 102 is formed in the liquid inlet section 11 and the suction inlet 101 is formed in the liquid inlet section 11, the lotion enters the flowing space 301 through the suction inlet 101, and the air enters the flowing space 301 through the air inlet 102, the lotion can enter the flowing space 301 through the suction inlet 101 and the air inlet 102, so that the lotion and the air are fully mixed before contacting with the water flow, and the lotion and the air are fully mixed in the flowing space 301 and then flow into the mixing section 12 to contact with the water flow, thereby further improving the dissolving effect and the foaming efficiency of the lotion, and further improving the cleaning effect. When the air inlet 102 is formed in the liquid inlet section 11 and the suction inlet 101 is formed in the mixing section 12, the lotion enters the mixing section 12 from the suction inlet 101, and the air firstly enters the flowing space 301 through the air inlet 102, and then the air enters the mixing section 12, so that the water flow, the lotion and the air are fully mixed, dissolved and foamed in the mixing section 12, the dissolving effect and the foaming effect of the lotion can be improved, and the cleaning effect is improved.
Optionally, the cross-section of the flow space 301 is annular extending around the ejector tube 3. Thereby, the flow space 301 is made large, so that the lotion and the gas can be sufficiently mixed in the flow space 301.
According to some embodiments of the present invention, referring to fig. 1, the injection pipe 3 comprises a main body section 31 connected to a side of the injection section 32 remote from the mixing section 12, the main body section 31 having an inner diameter larger than the inner diameter of the injection section 32. Therefore, in the process that water flows through the injection pipe 3, the water flows to the injection section 32 with the smaller inner diameter through the main body section 31 with the larger inner diameter for acceleration, the injection pipe 3 and the water inlet valve can be connected through the connecting hose, the connecting hose can be connected with the main body section 31 through the arranged main body section 31 with the larger inner diameter, the water flow is pressurized and accelerated by the injection pipe 3, meanwhile, the pressure born by the connecting hose can be reduced, and the risk of pipe explosion is reduced.
In some alternative embodiments of the present invention, referring to fig. 1, the injection pipe 3 may include a connection section 33, the connection section 33 connects the main body section 31 and the injection section 32, an outer side wall of the connection section 33 extends obliquely toward a direction adjacent to a central axis of the main body casing 1 in a direction from the main body section 31 to the injection section 32, a minimum inner diameter of the connection section 33 is not smaller than an inner diameter of the injection section 32, and the suction port 101 and the intake port 102 are both located upstream of the connection section 33 (the "suction port 101 and the intake port 102 are both located upstream of the connection section 33" means that the suction port 101 and the intake port 102 are both located upstream of the entire connection section 33, the upstream being with respect to a flow direction of the water flow). Thus, the change in the flow area between the main body segment 31 and the injection segment 32 is alleviated by the connection segment 33, and the flow loss can be reduced. Also, since the suction port 101 and the gas inlet port 102 are both located upstream of the connection section 33, the distance between the suction port 101 and the gas inlet port 102 and the injection section 32 of the injection pipe 3 can be further increased, so that the wash and the gas can be more sufficiently mixed in space and time before the wash and the gas contact the water flow. In addition, after the lotion sucked by the suction port 101 and the gas sucked by the gas inlet 102 enter the flow space 301, the lotion and the gas can more smoothly flow forward to contact with the water flow by the guiding action of the outer side wall of the connecting section 33.
According to some embodiments of the present invention, referring to fig. 1, the flow area of the mixing section 12 is smaller than the flow area of the inlet section 11 and the flow area of the mixing section 12 is smaller than the flow area of the outlet section 13, in which case the main pipe shell 11 itself may be formed as a venturi tube. In the process of mixing the lotion, the gas and the water flow in the mixing section 12, the mixing section 12 has a small flow area and a good turbulent motion effect, so that the mixing effect is good, the dissolving effect and the foaming effect of the lotion can be further improved, and the cleaning effect is improved.
Referring to fig. 1, a dispensing device for dispensing a lotion according to an embodiment of the second aspect of the present invention comprises: a dispensing assembly and a lotion storage box 4. The dispensing assembly is the dispensing assembly according to the above-mentioned first aspect of the present invention, the lotion storage box 4 is disposed outside the main pipe case 1 and connected to the main pipe case 1, the inner cavity of the lotion storage box 4 communicates with the suction port 101, and the lotion in the lotion storage box 4 is adapted to flow into the main pipe case 1 through the suction port 101.
Wherein, the lotion storage box 4 can be used for storing detergent, and the lotion storage box 4 can also be used for storing various types of lotions such as detergent, softener, disinfectant and the like.
