For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0041] Embodiment 1

[0042] Please refer to Figures 1 - 7 , this embodiment provides a water jet, including a water jet body 1. One end of the water jet body 1 is provided with a water inlet 11, the other end of the water jet body 1 is provided with a vibrating water outlet 12, and a water channel 13 for allowing water to flow through is provided inside the water jet body 1.

[0043] In this embodiment: The user can connect the water inlet 11 of the water knife body 1 to the water outlet pipe of the water pump, and then align the water outlet 12 with the surface of the tableware to be rinsed. Water flows into the water channel 13 from the water inlet 11, and then sprays out from the vibrating water outlet 12 through the water channel 13. Due to the vibration of the water outlet 12, impurities in the water body will not accumulate at the water outlet 12, and the generated water knife water curtain is uniform and complete, which can wash the dirt attached to the surface of the tableware clean, solving the problem that the water knife is prone to blockage during use, resulting in the splitting or scattering of the water knife water curtain, thereby affecting the decontamination effect.

[0044] Embodiment 2

[0045] Please refer to Figures 1 - 7 , based on Embodiment 1, this embodiment provides a water knife. The difference from Embodiment 1 is that the above-mentioned water outlet 12 is an arc groove, and the arc angle of the above-mentioned arc groove is 30 - 90°.

[0046] In this embodiment: The water outlet 12 is set in the shape of an arc groove. When water flows out from the water outlet 12, the water flow presents a fan-shaped spray relative to the water outlet 12, increasing the flushing range of the water flow. The arc angle of the arc groove is 30 - 90°. The smaller the arc angle, the thicker the thickness of the water curtain, and the longer the effective range of the water curtain; the larger the arc angle, the thinner the thickness of the water curtain, and the shorter the effective range of the water curtain. In addition, the thinner the thickness, the stronger the penetration ability and the more energy-saving. The user can set arc grooves with different arc angles according to actual needs.

[0047] Embodiment 3

[0048] Please refer to Figure 2 and Figure 3 , based on any one of the above embodiments, this embodiment provides a water knife. The difference from any one of the above embodiments is that the above-mentioned water channel 13 includes a first cavity 131 and a second cavity 132. The first cavity 131 is communicated with the water inlet 11, the second cavity 132 is communicated with the water outlet 12, and the first cavity 131 is communicated with the second cavity 132.

[0049] In this embodiment: The above-mentioned water channel 13 includes a first cavity 131 and a second cavity 132. Water flows into the first cavity 131 along the water inlet 11, then enters the second cavity 132, and finally sprays out from the water outlet 12. By setting the first cavity 131 and the second cavity 132, the first cavity 131 is used to buffer the water body, preventing the water body pressurized by the water pump from directly flushing into the second cavity 132, reducing the damage of impurities in the water body to the water outlet 12, and extending the service life of the water knife.

[0050] Embodiment 4

[0051] Please refer toFigure 2 and Figure 3 , based on any of the above embodiments, this embodiment provides a water jet, which is different from any of the above embodiments in that: the above water channel 13 further includes a third cavity 133, the above first cavity 131 and the above second cavity 132 are communicated through the above third cavity 133, and the diameter of the connection between the third cavity 133 and the first cavity 131 is smaller than that of the connection between the third cavity 133 and the second cavity 132.

[0052] In this embodiment: a third cavity 133 is provided between the first cavity 131 and the second cavity 132, and the diameter of the connection between the third cavity 133 and the first cavity 131 is smaller than that of the connection between the third cavity 133 and the second cavity 132. When the water flow flows from the first cavity 131 into the third cavity 133, due to the smaller diameter of the connection between the third cavity 133 and the first cavity 131, when the water flow passes through this connection, the flow rate of the water flow increases, and then the third cavity 133 and the subsequent second cavity 132 are scoured. While increasing the water flow rate, the third cavity 133 and the second cavity 132 are self-cleaned, reducing the maintenance cost.

[0053] Embodiment 5

[0054] Please refer to Figures 1 - 7 , based on any of the above embodiments, this embodiment provides a water jet, which is different from any of the above embodiments in that: the water jet body 1 includes a first splicing member 2, a second splicing member 3, and a telescopic assembly 4 for driving the second splicing member 3 to telescope. The telescopic assembly 4 is provided on the first splicing member 2, the telescopic end of the telescopic assembly 4 is connected to the second splicing member 3, the first cavity 131 and the third cavity 133 are both provided inside the first splicing member 2, the second cavity 132 includes a first splicing groove 1321 and a second splicing groove 1322, and the first splicing groove 1321 and the second splicing groove 1322 are respectively provided on the opposite side surfaces of the first splicing member 2 and the second splicing member 3.

[0055] In this embodiment: the user can control the distance between the second splicing piece 3 and the first splicing piece 2 through the telescopic component 4, thereby controlling the gap size of the water outlet 12 to achieve control of the water flow rate of the water outlet 12. In addition, when the water jet body 1 needs to be maintained, the user can separate the second splicing piece 3 from the first splicing piece 2 through the telescopic component 4, which is convenient for the user to maintain the components inside the water jet body 1. In addition, when there are more suspended matter in the water body, the resistance of the water outlet 12 increases, and the flow rate of the water curtain will slow down. The flow rate is inversely proportional to the pressure. The reduction in flow rate causes the pressure inside the waterway 13 to increase, and the high-pressure water squeezes the second splicing piece 3 and the first splicing piece 2 outward. When the outward pressure on the second splicing piece 3 is greater than the contraction pressure of the telescopic assembly 4, the second splicing piece 3 and the first splicing piece 2 will separate. The moment the second splicing piece 3 and the first splicing piece 2 separate, the gap of the water outlet 12 increases, and the resistance of the water outlet 12 decreases accordingly, and the water curtain speed increases accordingly. The flow rate is inversely proportional to the pressure. The increase in flow rate causes the internal pressure of the waterway 13 to decrease, so that the outward pressure on the second splicing piece 3 is less than the contraction pressure of the telescopic assembly 4. The second splicing piece 3 and the first splicing piece 2 are closed again, realizing the vibration cycle of the water outlet 12, and preventing the suspended matter in the water body from accumulating and clogging the water outlet 12.

[0056] In some other implementations of this embodiment, the telescopic assembly 4 may be any one of commercially available electric cylinders, electric hydraulic cylinders or electric mechanical telescopic arms.

[0057] In this embodiment, any one of the commercially available electric cylinders, electric hydraulic cylinders or electric mechanical telescopic arms can be used to drive the second splicing member 3 to extend and retract, and has the advantages of strong replaceability and low cost.

[0058] Example 6

[0059] Please refer to Figures 5 - 7 This embodiment provides a water knife based on any one of the above embodiments, and the difference from any one of the above embodiments is that the water outlet 12 includes a first lower edge 121 and a second lower edge 122, the first lower edge 121 is arranged at the bottom of the first splicing groove 1321, the second lower edge 122 is arranged at the bottom of the second splicing groove 1322, and the length of the first lower edge 121 is smaller than the second lower edge 122.

[0060] In this embodiment: the length of the first lower edge 121 is smaller than the second lower edge 122. When water flows out from the water outlet 12, due to the height difference between the first lower edge 121 and the second lower edge 122, the second lower edge 122 can play a vertical guiding role to ensure the verticality of the water curtain.

[0061] In some other embodiments of the present embodiment, the above-mentioned first lower edge 121 and the above-mentioned second lower edge 122 are both located above the bottom end of the water knife body 1.

[0062] In the present embodiment: The first lower edge 121 and the second lower edge 122 are both located above the bottom end of the water knife body 1, preventing the first lower edge 121 and the second lower edge 122 of the water knife from being knocked by foreign objects during actual use, resulting in dimensional deformation, and further causing the water curtain to scatter or deflect, ultimately scrapping the water knife body 1.

[0063] Embodiment 7

[0064] Please refer to Figures 1 - 7 Based on any one of the above embodiments, the present embodiment provides a water knife. The difference from any one of the above embodiments is that: the above-mentioned water knife body 1 further includes a limiting member 5, and the above-mentioned limiting member 5 is arranged between the above-mentioned first splicing member 2 and the above-mentioned second splicing member 3.

[0065] In the present embodiment: A limiting member 5 is arranged between the first splicing member 2 and the second splicing member 3. When the user contracts the second splicing member 3 through the telescopic assembly 4, the limiting member 5 can prevent the first splicing member 2 and the second splicing member 3 from being completely closed, resulting in mutual collision and damage between the first splicing member 2 and the second splicing member 3, and ensuring that there is a water outlet 12 for water to spray out between the first splicing member 2 and the second splicing member 3.

[0066] In some other embodiments of the present embodiment, the thickness of the above-mentioned limiting member 5 is 0.02 mm - 0.1 mm.

[0067] In the present embodiment: By setting the limiting member 5 with a thickness of 0.02 mm - 0.1 mm, the user can select limiting members 5 with different thicknesses according to actual needs, and then adjust the size of the water outlet 12 when the first splicing member 2 and the second splicing member 3 are clamped.

[0068] In some other embodiments of the present embodiment, the thickness of the above-mentioned limiting member 5 is 0.05 mm.

[0069] In the present embodiment: When the first splicing member 2 and the second splicing member 3 are clamped, the minimum size of the water outlet 12 is 0.05 mm. When the water flow velocity of the water sprayed out from the water outlet 12 is 43 m / s, it can penetrate the surface tension of animal and vegetable oils, effectively scrape the grease on the surface of tableware, and wash the grease and food residues in the micropores and micro-grooves on the surface of tableware clean.

[0070] Embodiment 8

[0071] Please refer to Figures 8 - 10, this embodiment is based on any of the above embodiments and provides a water knife machine. The difference from any of the above embodiments is that it includes a first water knife mounting assembly 6, a second water knife mounting assembly 7, a transport assembly 8, and two water knives as described above. The first water knife mounting assembly 6 is disposed above the transport assembly 8, the second water knife mounting assembly 7 is disposed below the transport assembly 8, the first water knife mounting assembly 6 and the second water knife mounting assembly 7 are symmetrically arranged with respect to the transport assembly 8, and the two water knives are symmetrically arranged above and below the transport assembly 8 on the first water knife mounting assembly 6 and the second water knife mounting assembly 7.

[0072] In this embodiment: The user can connect the water inlet 11 of the water knife to the water pump outlet pipe, and then place the tableware to be washed on the transport assembly 8. The transport assembly 8 transports the tableware in sequence. When the tableware passes through the first water knife mounting assembly 6 and the second water knife mounting assembly 7, the water outlets 12 of the water knives symmetrically arranged above and below wash the tableware, scraping off the dirt attached to the surface of the tableware, and solving the problem that the existing large-aperture dot spraying requires hot water and detergent soaking to remove oil and dirt.

[0073] Embodiment 9

[0074] Please refer to Figures 8 - 10 , this embodiment is based on any of the above embodiments and provides a water knife machine. The difference from any of the above embodiments is that several groups of the above water knives are provided on the first water knife mounting assembly 6 and the second water knife mounting assembly 7.

[0075] In this embodiment: By setting several groups of water knives on the first water knife mounting assembly 6 and the second water knife mounting assembly 7, on the one hand, the width of the water knife is increased, thereby increasing the washing efficiency of the water knife machine; on the other hand, the tableware on the transport assembly 8 can be washed multiple times to ensure that the water knife machine can completely wash off the dirt attached to the surface of the tableware.

[0076] Embodiment 10

[0077] Please refer to Figures 8 - 10 , this embodiment is based on any of the above embodiments and provides a water knife machine. The difference from any of the above embodiments is that the first water knife mounting assembly 6 includes a lifting frame 61 and a fixed frame 62. The lifting frame 61 is slidably connected to the fixed frame 62 up and down, and the water knife is disposed on the lifting frame 61.

[0078] In this embodiment: The water knife is arranged on the lifting frame 61 and cooperates with the fixed frame 62. When the transportation component 8 transports the tableware, the tableware lifts the lifting frame 61. At the same time, the lifting frame 61 slides downward along the fixed frame 62 under its own gravity, forcing the lower surface of the lifting frame 61 to closely adhere to the upper surface of the tableware, thereby ensuring that the water outlet 12 of the water knife closely adheres to the upper surface of the tableware, and finally ensuring that the tableware passes through smoothly and evenly under the high-speed water jet.

[0079] In some other embodiments of this embodiment, the above-mentioned transportation component 8 is provided with a number of baffles 81 that move along with the above-mentioned transportation component 8.

[0080] In this embodiment: The baffle 81 cooperates with the transportation component 8 to transport the tableware. The baffle 81 can limit the position of the tableware to prevent the tableware from slipping off the transportation component 8. In addition, when the tableware contacts the lower surface of the above-mentioned lifting frame 61, the baffle 81 plays a limiting role to ensure that the tableware can lift the lifting frame 61, thereby ensuring that the water outlet 12 of the water knife closely adheres to the upper surface of the tableware, and finally ensuring the flushing effect of the water knife machine.

[0081] In some other embodiments of this embodiment, the bottom of the above-mentioned lifting frame 61 is provided with a first pressing plate 611 and a second pressing plate 612. The above-mentioned second pressing plate 612 is located on the right side of the above-mentioned first pressing plate 611. A gap 613 for inserting the above-mentioned water outlet 12 of the water knife is provided between the above-mentioned first pressing plate 611 and the above-mentioned second pressing plate 612.

[0082] In this embodiment: The first pressing plate 611 and the second pressing plate 612 help the lower surface of the lifting frame 61 to better adhere to the upper surface of the tableware. The gap 613 facilitates the installation of the water outlet 12 of the water knife and can also ensure that the water flow ejected from the water outlet 12 of the water knife can directly spray onto the upper surface of the tableware, and finally ensure the flushing effect of the water knife machine.

[0083] In some other embodiments of this embodiment, one end of the above-mentioned first pressing plate 611 away from the above-mentioned gap 613 is provided with a first guiding slope 6111, and one end of the above-mentioned second pressing plate 612 away from the above-mentioned gap 613 is provided with a second guiding slope 6121.

[0084] In this embodiment: When the upper side wall of the tableware contacts the first guiding slope 6111, the first guiding slope 6111 can cooperate with the baffle 81 to easily and evenly lift the lifting frame 61, preventing the lifting frame 61 from directly contacting the tableware and causing damage to the tableware. The second guiding slope 6121 can cooperate with the baffle 81 to evenly lower the lifting frame 61, preventing the lifting frame 61 from directly falling and causing damage to the subsequent tableware.

[0085] Effect example

[0086] The water jet machine of the above embodiment is used to wash the test tableware with grease, glutinous rice and fluorescent paint on its surface, and the washing results are as follows Figure 11 and Figure 12 shown

[0087] Figure 11 In , the water temperature of the water jet water curtain is 20°C, the effective range of the water curtain of the water jet is ≤230 mm, the width of the water curtain of the water jet is 200 mm, the thickness of the water curtain of the water jet is 0.02 mm, and the mixing ratio of the grease, glutinous rice and fluorescent paint attached to the surface of the test tableware is 3:1:0.2. Among them, the grease, glutinous rice and fluorescent paint are respectively used to simulate the oil stains, food residues and bacteria remaining on the surface of the test tableware Figure 12 In Figure 12 , the water temperature of the water jet water curtain is 20°C, the effective range of the water curtain of the water jet is ≤230 mm, the width of the water curtain of the water jet is 200 mm, the thickness of the water curtain of the water jet is 0.02 mm, and a purple light lamp is used to identify the remaining fluorescent agent Figure 11 and Figure 12 In Figure 11 and Figure 12 , the vertical axis is the water curtain flow velocity Figure 11 and Figure 12 In Figure 11 and Figure 12 , the horizontal axis is the scraping surface area. Among them, dividing the scraping surface area by the width of the water curtain can obtain the rate of the transport component 8 transporting the test tableware

[0088] From Figure 11 it can be known that when the water curtain flow velocities reach 43 m / s and 63 m / s respectively, the edible oil and engine oil respectively appear the peeling critical points. That is, when the water curtain flow velocity reaches this speed value, without detergent and hot water, the water flow can peel the edible oil and engine oil from the surface of the stationary test tableware. At this time, the scraping surface area is 10 cm 2 / s, and the converted rate of the transport component 8 transporting the test tableware is 0.5 cm / s. That is, when the water curtain flow velocities reach 43 m / s and 63 m / s respectively and when the rate of transporting the test tableware ≤0.5 cm / s, the water flow can peel the edible oil and engine oil from the surface of the test tableware transported by the transport component 8. After that, the greater the water curtain flow velocity, the higher the speed of the water jet machine for transporting tableware can be increased, and the washing efficiency of the water jet machine can be increased

[0089] From Figure 12 it can be known that when the water curtain flow velocity reaches 42 m / s, the fluorescent agent appears the peeling critical point. That is, when the water curtain flow velocity reaches this speed value, without detergent and hot water, the water flow can peel the fluorescent agent from the surface of the stationary test tableware. At this time, the scraping surface area is 25 cm 2 / s, when converted to the rate at which the transportation component 8 transports the test tableware, it is 1.25 cm / s. That is, when the water curtain flow rate reaches 42 m / s and when the rate of transporting the test tableware ≤ 1.25 cm / s, the water flow can strip the fluorescent agent from the surface of the test tableware transported by the transportation component 8. After that, the greater the water curtain flow rate, the higher the speed of the waterjet machine for transporting tableware can be increased, improving the flushing efficiency of the waterjet machine.

[0090] In summary, the embodiments of the present invention provide a waterjet and a waterjet and air knife machine, which at least have the following beneficial effects:

[0091] A waterjet includes a waterjet body 1. One end of the waterjet body 1 is provided with a water inlet 11, the other end of the waterjet body 1 is provided with a water outlet 12, and a water channel 13 for allowing water flow to pass through and increasing the water flow rate is provided inside the waterjet body 1.

[0092] The user can connect the water inlet 11 of the waterjet body 1 to the water pump outlet pipe, and then align the water outlet 12 with the surface of the tableware to be blown and washed. The water flow enters the water channel 13 from the water inlet 11, passes through the water channel 13, and sprays out from the water outlet 12, generating a high-speed and high-pressure water flow to wash away the dirt attached to the surface of the tableware, solving the problem that the waterjet is prone to blockage during use, resulting in the water curtain of the waterjet splitting or scattering, thereby affecting the oil and dirt removal effect of the waterjet.

[0093] A waterjet machine includes a first waterjet installation component 6, a second waterjet installation component 7, a transportation component 8, and two waterjets as described above. The first waterjet installation component 6 is provided above the transportation component 8, the second waterjet installation component 7 is provided below the transportation component 8, the first waterjet installation component 6 and the second waterjet installation component 7 are symmetrically arranged with respect to the transportation component 8, and the two waterjets are symmetrically arranged above and below the transportation component 8 on the first waterjet installation component 6 and the second waterjet installation component 7.

[0094] The user can connect the water inlet 11 of the waterjet to the water pump outlet pipe, and then place the tableware to be washed on the transportation component 8. The transportation component 8 transports the tableware in sequence. When the tableware passes through the first waterjet installation component 6 and the second waterjet installation component 7, the water outlets 12 of the waterjets symmetrically arranged above and below wash the tableware to wash away the dirt attached to the surface of the tableware, solving the problem that the spraying of existing dishwashers requires hot water and detergents to emulsify and decompose oil and dirt, resulting in difficult control of tableware detergent residues, high treatment costs for detergent-containing wastewater and waste gas emissions from boilers for heating hot water, and thus making it difficult for dishwashing enterprises to control product quality and having high operating costs.

[0095] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
