[0002] With the advancement of technology and the continuous improvement of people's living standards, the market demand for household cleaning machines is becoming increasingly widespread. For example, cleaning machines are used to automatically clean drinking water bottles and baby bottles. The cleaning effect of the cleaning machine is directly related to the user experience and health and safety. However, there are many problems that need to be solved in the cleaning machines currently on the market.

[0003] Traditional fixed spray structures have fixed spray nozzle positions and angles, which can only rinse specific areas of the item. For the inner walls of deep containers and the threaded parts of the bottle mouth, the water flow of fixed spray is difficult to cover, which can easily create cleaning blind spots, resulting in incomplete cleaning and poor cleaning effect.

[0004] Therefore, in order to solve the problem that the existing spray structure of the cleaning machine is prone to blind spots, resulting in poor cleaning effect, it is necessary to develop a spray mechanism and cleaning machine. Utility Model Content

The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0026] Please see Figures 1 to 6 The spraying mechanism shown includes a spray column 1, a first fixed spraying assembly 2 connected to the spray column 1, and a first rotating spraying assembly 3 connected to the first fixed spraying assembly 2. A liquid channel is provided between the spray column 1, the first fixed spraying assembly 2, and the first rotating spraying assembly 3. The first rotating spraying assembly 3 includes a plurality of first rotating spraying elements 31 rotatably connected to the first fixed spraying assembly 2. The first rotating spraying elements 31 are provided with first spray nozzles 311 for spraying liquid.

[0027] In this invention, a liquid channel is provided between the first fixed spray assembly and the first rotating spray assembly to deliver cleaning liquid from a water pump or water source to each spray nozzle. The spray column is the central support structure of the entire spray mechanism. The first fixed spray assembly is connected to multiple first rotating spray components, and each first rotating spray component is provided with a first spray nozzle for liquid spraying. By setting multiple first rotating spray components to spray and rinse the cleaning object individually, the water flow rinsing frequency is effectively increased while expanding the cleaning coverage area and reducing cleaning blind spots. Especially when multiple cleaning objects are placed in the cleaning chamber at the same time, the existing single rotating spray structure will cause an increase in cleaning blind spots due to the stacking of bottles, making it impossible to effectively clean the bottles. However, the multiple first rotating spray components of this invention effectively solve the problem of increased cleaning blind spots caused by bottle stacking. In this invention, the cleaning object can be a thermos, a baby bottle, a sports water bottle, and a nipple, etc.

[0028] Furthermore, such as Figure 6 , Figure 7 As shown, the first fixed spray assembly 2 includes a connecting arm 21 connected to the spray column 1 and a plurality of first fixed spray arms 22 connected to the connecting arm 21. The first rotating spray member 31 is rotatably disposed on the upper side and / or lower side of the connecting arm 21. The first fixed spray arm 22 is provided with a second spray nozzle 221 for liquid to be sprayed out.

[0029] In this invention, the connecting arm is connected to the spray column and is connected to a plurality of first fixed spray arms, preferably 2-6. Each first fixed spray arm is provided with a first spray nozzle for targeted rinsing of the interior of the object to be cleaned in the cleaning chamber. The first rotating spray component is rotatably disposed on the upper side and / or lower side of the connecting arm. The two are rotatably connected by a rotating connection structure, wherein the rotating connection structure can be a bearing, bushing or other low-friction rotating structure.

[0030] Furthermore, in this utility model, the number of the first rotating spray members may be the same as or different from the number of the first fixed spray members, and this utility model does not make a specific limitation.

[0031] As a preferred embodiment of this utility model and not a limitation, the first rotating spray member corresponds one-to-one with the first fixed spray arm in the vertical direction, meaning that the number of the first rotating spray members is the same as the number of the first fixed spray arms and they are arranged in a one-to-one correspondence. Each of the first rotating spray members is provided with a second spray nozzle. Each of the first rotating spray members can independently rotate and rinse each bottle. Compared with the traditional rotating spray structure of the washing machine, this structure can effectively increase the cleaning area of ​​the rotating spray member, ensure that the rotating spray member can effectively rinse the bottle, eliminate cleaning blind spots, improve cleaning coverage, and thus improve the cleaning effect of the washing machine. It avoids the problem of increased cleaning dead corners caused by the accumulation of multiple bottles in the cleaning chamber, which ultimately leads to a reduction in cleaning effect.

[0032] Furthermore, the first fixed spray assembly 2 also includes a first connecting portion 211 for connecting the first rotating spray member 31. The first rotating spray member 31 includes a first rotating portion 312 rotatably connected to the first connecting portion 211 and a first rotating spray arm 313 connected to the first rotating portion 312. The first spray nozzle 311 is located at the first rotating spray arm 313. When liquid is sprayed from the first spray nozzle 311, it can drive the first rotating spray member 31 to rotate about the first connecting portion 211 as an axis.

[0033] In one alternative embodiment of the first rotating spray element, such as Figure 6As shown, the first rotating spray component is disposed on the lower side of the connecting arm, and the first connecting portion can be correspondingly disposed on the lower side of the connecting arm. Optionally, the bottom of the connecting arm is provided with an extension portion, which provides space for the first connecting portion. The first connecting portion is disposed at the extension portion. The first rotating spray component is provided with a first rotating portion rotatably connected to the first connecting portion. Through the rotatable connection between the first connecting portion and the first rotating portion, the first rotating spray component can rotate freely around the first connecting portion. The first rotating spray arm is connected to one end of the first rotating portion, and the first spray nozzle is disposed on the first rotating spray arm. Both the connecting arm and the first rotating spray component are provided with liquid channels for liquid flow, and the first connecting portion is provided with a water outlet for liquid to pass through. Liquid can flow from the liquid channels in the spray column to... The liquid flows through the connecting arm's liquid channel and then through the outlet hole of the first connecting part into the liquid channel of the first rotating spray component, finally spraying out from the first spray nozzle. The reaction force generated by the liquid spraying out of the first spray nozzle can drive the first rotating component to rotate around the first connecting part as an axis. This structural design does not require an additional motor drive and relies on the principle of fluid dynamics to achieve the self-rotation function, simplifying the structural design of the cleaning machine and improving the overall reliability and service life of the equipment. In summary, through the design of the connecting arm and the first rotating spray component, a combination of fixed and rotating double-layer spray structure is achieved, which can significantly expand the spray range without increasing the volume and energy consumption. The fixed spray arm is responsible for basic rinsing of the bottle interior, while the first rotating spray component dynamically covers the bottle neck threads, the exterior of the bottle body, and other positions, eliminating cleaning blind spots and improving cleaning coverage.

[0034] In another optional embodiment of the first rotating spray member, this embodiment differs from the above-described embodiment of the first rotating spray member in that, as Figure 7 As shown, the first rotating spray member is disposed on the upper side of the connecting arm, and the first connecting part is correspondingly disposed on the upper side of the connecting arm, with the first connecting part located between the first fixed spray arm and the connecting arm. Optionally, the first rotating spray member can be directly connected to the connecting arm, or it can be directly connected to the first fixed spray arm. This utility model does not make specific limitations. For example, if the first rotating spray member is directly connected to the connecting arm, the upper part of the connecting arm is provided with an extension, and the first connecting part is disposed on the extension. Or, for example, if the first rotating spray member is directly connected to the first fixed spray arm, the first connecting part is correspondingly disposed on the first fixed spray arm.

[0035] Furthermore, the first rotating spray member 31 is provided with at least two first rotating spray arms 313, and the first spray nozzle 311 is provided on the upper side of the first rotating spray arm 313. When the liquid is sprayed out from the first spray nozzle 311, it can drive the first rotating spray member 31 to rotate. The upper side of the first rotating spray arm 313 is provided with a fourth spray nozzle 314.

[0036] In this invention, the first rotating spray component is mounted on the connecting arm and can rotate freely around the first connecting part. Each first rotating spray component has at least two first rotating spray arms, preferably 2-4. The first rotating arm has a liquid channel for conveying cleaning liquid to the first spray port. Further, the first spray port is located on the upper side of the first rotating spray arm, and the opening direction of the first spray port is inclined along the long side of the first rotating spray arm, that is, the axis of the first spray port forms a certain angle with the longitudinal direction of the first rotating spray arm, so that the water flow has a tangential component. When the liquid is sprayed out of the port at high speed, a reaction torque is generated, which drives the first rotating spray component to rotate. In addition, the fourth spray port is another spray port of the first rotating spray arm, which is located on the upper side of the first rotating spray arm and its opening direction is vertically upward, forming a composite spray function with the first spray port, further improving the cleaning efficiency and comprehensiveness of the spray mechanism.

[0037] As a preferred embodiment of the present invention and not a limitation thereof, each of the first rotating spray components is provided with two first rotating spray arms. The two first rotating spray arms are respectively connected to the opposite sides of the first rotating part to form a symmetrical arrangement on both sides. With this design, when the cleaning liquid is sprayed out from the second spray nozzle, the first rotating spray component is subjected to more uniform force and rotates more smoothly.

[0038] Furthermore, it includes a second rotating spray assembly 4, which includes a second rotating spray member 41 rotatably connected to the spray column 1. The second rotating spray member 41 is provided with a third spray nozzle 411, and when liquid is sprayed out from the third spray nozzle 411, it can drive the second rotating spray member 41 to rotate.

[0039] In this invention, the second rotating spray component is another rotating spray mechanism in the cleaning machine besides the first rotating spray component. The second rotating spray component is provided with a third spray nozzle and a liquid channel for liquid flow. The cleaning liquid flows from the liquid channel of the spray column to the second rotating spray component and is then sprayed out from the third spray nozzle of the second rotating spray component. The reaction force generated by the sprayed water can drive the second rotating spray component to rotate around the axis of the spray column. In summary, the design of the second rotating spray component further expands the cleaning coverage of the spray mechanism and improves the cleaning effect of the cleaning machine. Specifically, the second rotating spray component is located above the first rotating spray component and is used to spray and rinse the upper or middle area of ​​the object to be cleaned. Combined with the first rotating spray component, it forms a rotating spray mechanism for different areas, further improving the cleaning range and cleaning effect of the spray mechanism.

[0040] Furthermore, the top of the spray column 1 is provided with a second connecting part 11, and the second rotating spray member 41 includes a second rotating part 412 rotatably connected to the second connecting part 11 and a second rotating spray arm 413 connected to the second rotating part 412. The third spray nozzle 411 is located at the second rotating spray arm 413. When the liquid is sprayed out from the third spray nozzle 411, it can drive the second rotating spray member 41 to rotate about the second connecting part 11 as an axis.

[0041] In this invention, the second connecting part is located at the top of the spray column, and the second rotating spray component is provided with a second rotating part that cooperates with the second connecting part. Through the cooperation between the second connecting part and the second rotating part, the second rotating spray component can rotate around the second connecting part as an axis, realizing the rotatable connection between the second rotating spray component and the second connecting part. Specifically, the second connecting part is provided with a water outlet for liquid to pass through. The cleaning liquid in the liquid channel of the spray column can enter the liquid channel in the second rotating spray component through the water outlet of the second connecting part, and finally spray out from the fourth spray port. This achieves cleaning of the object while the reaction torque generated by the water flow drives the second rotating spray component to rotate around the second connecting part, realizing dynamic spray cleaning, significantly expanding the cleaning coverage area, and effectively avoiding the occurrence of cleaning blind spots.

[0042] As a preferred embodiment of the present invention and not a limitation thereof, the third spray nozzle is located on the upper side of the second rotating spray member, and the cleaning liquid is sprayed upward from the third spray nozzle to spray the cleaning object on the upper side of the second rotating spray member. The spray column extends to the upper or middle part of the cleaning chamber, further improving the cleaning efficiency and cleaning coverage of the spray mechanism for the cleaning object.

[0043] Optionally, two adjacent first rotating spray elements 21 are staggered in the vertical direction.

[0044] In some embodiments of this utility model, two adjacent first rotating spray elements are staggered in the vertical direction, meaning that in the height direction, two adjacent first rotating spray elements are not on the same horizontal plane, that is, one first rotating spray element is slightly higher than the other, forming a stepped or staggered arrangement. This design can avoid mechanical interference between adjacent first rotating spray elements, and at the same time, more first rotating spray elements can be set in the same unit space to form a denser jet of water to clean the object, effectively improving the cleaning efficiency and space utilization of the spray mechanism.

[0045] Optionally, several of the first rotating spray elements 31 are located on the same plane.

[0046] In other embodiments of this utility model, several of the first rotating spray elements are on the same plane, which means that multiple first rotating spray elements operate on the same plane, which facilitates the rotation direction and coverage area, and the spray paths between each first rotating spray arm are less likely to cross and interfere with each other, effectively improving the cleaning efficiency.

[0047] Furthermore, the number of connecting arms 21 is at least two, and each connecting arm 21 is connected to at least two first fixed spray arms 22. The third spray nozzle 411 is provided in multiple ways and is evenly arranged on the upper side of the second rotating spray member 41 along the circumference of the spray column 1.

[0048] In this invention, at least two of the connecting arms are simultaneously connected to the spray column and distributed within the cleaning chamber. By providing multiple connecting arms, the space utilization efficiency within the cleaning chamber is further improved. In addition, multiple third spray nozzles are provided, preferably 3-6, and these multiple third spray nozzles are evenly distributed along the circumference of the spray column, enabling the second rotating spray component to achieve dynamic spraying of multiple water streams during rotation, thereby further improving the cleaning effect of the spray mechanism.

[0049] As a preferred embodiment of this utility model and not a limitation thereof, the two connecting arms are respectively connected to opposite sides of the spray column to form a symmetrical arrangement on both sides, which improves the cleaning effect while ensuring the uniformity of the spray water flow in the cleaning chamber.

[0050] In another embodiment of this utility model, the three connecting arms are connected to the side of the spray column and are evenly distributed along the periphery of the spray column.

[0051] A cleaning machine, including a cleaning machine body, wherein the cleaning machine body includes any one of the spraying mechanisms described above.

[0052] Furthermore, the cleaning machine body includes an electric pump 5 and a cleaning chamber 6, the spraying mechanism is disposed in the cleaning chamber 6, the electric pump 5 is connected to the spray column 1, and the cleaning machine body includes a cleaning bracket 7 disposed in the cleaning chamber 6, the cleaning bracket 7 including a bottle bracket 71 and a nipple bracket 72.

[0053] The cleaning machine described in this utility model achieves efficient cleaning of the object by integrating the spray mechanism and combining it with the electric pump and the cleaning chamber in a reasonable layout. The spray mechanism adopts a combination of fixed and rotating design to ensure that the cleaning liquid can cover every corner of the object in the cleaning chamber. It is especially suitable for cleaning the inner walls of deep-mouthed containers such as baby bottles, thermos cups, and sports water bottles, as well as the threads of the bottle mouth, which are difficult to reach by traditional cleaning methods. This effectively improves the cleaning efficiency and cleaning effect of the cleaning machine. Furthermore, the cleaning chamber is equipped with a bottle bracket for fixing the water bottle and a nipple bracket for fixing the nipple. The design of the bottle bracket ensures that the water bottle can be fixed in a fixed posture in the cleaning chamber and is set in accordance with the preset spray mechanism. This design ensures that the spray mechanism can effectively clean the water bottle and prevent it from shaking and failing to rinse effectively, further ensuring the cleaning effect of the cleaning machine.
