Description

Technical Field

[0001] This application belongs to the field of cleaning technology, and more specifically, relates to a cleaning machine and its water inlet assembly. Background Technology

[0002] The cleaning machine can wash the items to be cleaned in the cleaning chamber. The cleaning machine needs to add cleaning fluid into the cleaning chamber through the water inlet component.

[0003] In related technologies, the water inlet component of the cleaning machine is a breather. To prevent the cleaning fluid in the cleaning chamber from flowing back, the breather has a complex flow guiding structure inside, which increases production costs. Utility Model Content

[0004] The purpose of this application is to provide a cleaning machine and its water inlet assembly to reduce production costs.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a water inlet assembly for a cleaning machine is provided. The water inlet assembly includes a water inlet shell, the water inlet shell having a cavity and a water inlet hole and a water outlet hole communicating with the cavity, the water outlet hole being used to communicate with the cleaning chamber of the cleaning machine, and the lowest point of the water inlet hole being higher than the lowest point of the water outlet hole.

[0007] Through the above technical solution, the cleaning fluid can enter the cavity through the inlet hole and then enter the cleaning chamber of the cleaning machine through the outlet hole, thus adding water to the cleaning chamber. Furthermore, the lowest point of the inlet hole is higher than the lowest point of the outlet hole, meaning the cleaning fluid in the cavity preferentially flows out through the outlet hole compared to the inlet hole, which helps prevent the cleaning fluid in the cavity from entering the inlet hole, thereby preventing backflow. In addition, the inlet shell has a cavity, a simple internal structure, is easy to manufacture, and helps reduce production costs.

[0008] Therefore, the water inlet component provided in this application can reduce production costs and help prevent backflow of cleaning fluid.

[0009] In some implementations, the lowest point of the water outlet is not higher than the lowest point of the cavity.

[0010] In this way, the cleaning fluid in the cavity can flow out smoothly from the water outlet, which helps to prevent the cleaning fluid from accumulating in the cavity.

[0011] In some implementations, the water inlet housing is integrally molded. This eliminates the need for seams in the water inlet housing, preventing leakage of the cleaning fluid.

[0012] In some embodiments, the water inlet assembly provided in this application further includes a water inlet pipe, which is connected to the water inlet shell and communicates with the water inlet hole, and the water inlet pipe and the water inlet shell are integrally formed.

[0013] In this way, there is no connection seam between the water inlet pipe and the water inlet shell, which can prevent the cleaning fluid from leaking.

[0014] In some embodiments, the water inlet shell is a cylindrical structure with an opening at one end, and the water outlet is located at one end of the water inlet shell, forming the opening. The water inlet is located on the peripheral wall of the water inlet shell.

[0015] In this way, the direction of the water inlet is different from that of the water outlet, so the cleaning fluid splashed into the cavity from the water outlet is less likely to enter the water inlet, thus helping to prevent the cleaning fluid from flowing back.

[0016] In some embodiments, the inlet housing is a cylindrical or conical structure. This makes the inner circumferential surface of the inlet housing cylindrical or conical, which facilitates the return of cleaning fluid splashed onto the inner circumferential surface of the inlet housing to the bottom.

[0017] In some embodiments, the inlet shell has a conical structure, and the radial dimension of the cavity gradually increases along the direction close to the opening;

[0018] Alternatively, the inlet shell may be a cylindrical structure, with the thickness of the inlet shell's peripheral wall gradually decreasing towards the opening.

[0019] In this way, the cavity is a conical cavity, and the lowest point of the cavity at the end furthest from the opening is higher than the lowest point at the end closest to the opening. The cleaning fluid in the cavity can flow out smoothly from the outlet hole and will not accumulate in the cavity, thus helping to prevent the cleaning fluid from flowing back in.

[0020] In some embodiments, the water inlet assembly provided in this application further includes a mounting bracket, which includes a first mounting plate and a second mounting plate. The first mounting plate and the second mounting plate are arranged at an angle. The first mounting plate is connected to the water inlet shell and is used to support the water inlet shell. The second mounting plate is used to connect to the cleaning chamber of the cleaning machine.

[0021] Through the above technical solution, the water inlet assembly provided in this application can use the first mounting plate to support the water inlet shell, so that the water outlet of the water inlet shell can be connected to the cleaning chamber at one position, and can also use the second mounting plate to connect to the cleaning chamber of the cleaning machine at another position. Therefore, the water inlet assembly is stably installed in the cleaning chamber of the cleaning machine through the mounting bracket.

[0022] In some embodiments, the water inlet assembly provided in this application further includes a sealing ring, which surrounds the outer periphery of the water inlet shell and is located close to the opening. The sealing ring is used to be located at the connection between the water outlet and the cleaning chamber.

[0023] In this way, the sealing ring can seal the connection between the water outlet and the cleaning chamber, which helps to prevent the cleaning fluid from leaking.

[0024] In some embodiments, the first mounting plate surrounds the outer periphery of the water inlet shell and is located close to the opening, and the sealing ring is located on the side of the first mounting plate close to the opening;

[0025] The sealing ring includes a first sealing part and a second sealing part. The first sealing part is attached to the outer peripheral surface of the water inlet shell, and the second sealing part is attached to the side surface of the first mounting plate near the opening.

[0026] In this way, the sealing ring can achieve two seals through the first sealing part and the second sealing part, which helps to improve the sealing effect.

[0027] Secondly, this application provides a cleaning machine, which includes a cleaning chamber and a water inlet assembly according to any of the above embodiments. The cleaning chamber has a cleaning cavity and a mounting hole communicating with the cleaning cavity. The water inlet shell is installed in the cleaning chamber through the mounting hole, and the water outlet is directly communicating with the cleaning cavity.

[0028] The cleaning machine provided in this application has the same or similar technical effects as the water inlet assembly of any of the above embodiments, and will not be described again here. In addition, the water outlet is directly connected to the cleaning chamber, which can reduce intermediate parts, improve the speed at which the cleaning fluid enters the cleaning chamber, and reduce the risk of cleaning fluid leakage.

[0029] In some embodiments, the water inlet assembly further includes a mounting bracket, which includes a first mounting plate and a second mounting plate. The first mounting plate and the second mounting plate are arranged at an angle. The first mounting plate is connected to the water inlet shell and is used to support the water inlet shell.

[0030] The cleaning chamber also includes a connecting column, which is located on two adjacent sides of the cleaning chamber, along with the mounting hole. The second mounting plate is connected to the connecting column.

[0031] In this way, in the cleaning machine provided by this application, the first mounting plate and the second mounting plate of the mounting frame are respectively connected to two adjacent sides of the cleaning chamber, which is beneficial to the compactness of the structure.

[0032] In some implementations, there are multiple connecting columns, and the cleaning chamber also includes a support plate connecting two adjacent connecting columns.

[0033] In this way, the support plate can increase the strength of the connecting column, which helps to prevent the connecting column from deforming. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] Please see Figure 1 This application provides a cleaning machine 100, which includes a cleaning chamber 110 with a cleaning cavity 111. Items to be cleaned can be placed in the cleaning cavity 111 for cleaning. The cleaning machine 100 needs to add cleaning fluid to the cleaning cavity 111 to clean the items. The cleaning fluid can be water or a mixture of water and detergent, etc.

[0052] The cleaning machine 100 provided in this application embodiment can be a baby bottle cleaning machine, which can be used to clean baby bottles, nipples, breast pumps or other maternal and infant products. Of course, the cleaning machine 100 can also be used to clean food, tableware, etc.

[0053] In related technologies, cleaning machines use a breather to add cleaning fluid into the cleaning chamber. To prevent the cleaning fluid from flowing back into the cleaning chamber, the breather is usually equipped with a complex flow guiding structure, which increases production costs.

[0054] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5To solve the above-mentioned technical problems, this application provides a water inlet assembly 120, which includes a water inlet shell 1. The water inlet shell 1 has a cavity 101 and a water inlet hole 102 and a water outlet hole 103 communicating with the cavity 101. The water outlet hole 103 is used to communicate with the cleaning chamber 111 of the cleaning machine 100. Therefore, the cleaning liquid can enter the cavity 101 through the water inlet hole 102 and then enter the cleaning chamber 111 of the cleaning machine 100 through the water outlet hole 103, thereby adding water to the cleaning chamber 111 of the cleaning machine 100.

[0055] The lowest point of the inlet hole 102 is higher than the lowest point of the outlet hole 103. Compared with the inlet hole 102, the cleaning fluid in the cavity 101 flows out preferentially from the outlet hole 103, which helps to prevent the cleaning fluid in the cavity 101 from entering the inlet hole 102, thus preventing backflow of the cleaning fluid. In addition, the interior of the water inlet shell 1 is a cavity 101, which has a simple internal structure, is easy to process, and helps to reduce production costs.

[0056] Therefore, the water inlet component 120 provided in this application embodiment can reduce production costs and help prevent backflow of cleaning fluid.

[0057] Optionally, the cleaning machine 100 provided in this application embodiment also includes a water tank for storing cleaning fluid, and a water inlet 102 for connecting to the water tank of the cleaning machine 100, so that the cleaning fluid in the water tank can enter the cavity 101 of the water inlet shell 1 through the water inlet 102, and then be added to the cleaning chamber 111 through the water outlet 103.

[0058] Optionally, the cleaning machine 100 provided in this application embodiment also includes a water supply component, which is connected to a water tank and a water inlet 102. In this way, the cleaning fluid in the water tank can be transported to the water inlet 102 through the water supply component.

[0059] Optionally, the water delivery assembly may include a delivery pump that can extract cleaning fluid from the water tank and pump it into the water inlet 102. The delivery part may be a diaphragm pump or the like.

[0060] Optionally, the water supply assembly may also include a water supply pipe that can be connected to the water inlet 102. The water supply pipe may be a flexible hose, allowing it to be deformable and thus avoid other components.

[0061] In some embodiments, the lowest point of the water outlet 103 is not higher than the lowest point of the cavity 101. In this way, the cleaning fluid in the cavity 101 can flow out smoothly from the water outlet 103, which helps to prevent the cleaning fluid from accumulating in the cavity 101, and thus helps to prevent the cleaning fluid from flowing back into the water inlet 102.

[0062] In some embodiments, the cleaning chamber 110 has a mounting hole 112 communicating with the cleaning cavity 111, the water inlet shell 1 is installed in the cleaning chamber 110, and the water outlet 103 is directly communicating with the cleaning cavity 111.

[0063] The cleaning machine 100 provided in this application embodiment has the same or similar technical effects as the water inlet assembly 120 in any of the above embodiments, and will not be described again here. In addition, the water outlet 103 is directly connected to the cleaning chamber 111, which can reduce intermediate parts, improve the speed at which the cleaning fluid enters the cleaning chamber 111, and reduce the risk of cleaning fluid leakage.

[0064] Please continue reading. Figure 3 , Figure 4 and Figure 5 In some embodiments, the water inlet assembly 120 provided in this application also includes a mounting bracket 3. The mounting bracket 3 includes a first mounting plate 31 and a second mounting plate 32. The first mounting plate 31 and the second mounting plate 32 are arranged at an angle. The first mounting plate 31 is connected to the water inlet shell 1 and is used to support the water inlet shell 1. The second mounting plate 32 is used to connect to the cleaning chamber 110 of the cleaning machine 100.

[0065] Optionally, the first mounting plate 31 is perpendicular to the second mounting plate 32, and the included angle between the first mounting plate 31 and the second mounting plate 32 is 90°. The connection between the first mounting plate 31 and the water inlet shell 1 is on the outside of the water inlet shell 1, so there is no need to worry about cleaning fluid leakage. Therefore, the connection method between the first mounting plate 31 and the water inlet shell 1 can be threaded connection, snap-fit ​​connection, welding, integral connection, etc.

[0066] In this way, the water inlet assembly 120 provided in this application embodiment can use the first mounting plate 31 to support the water inlet shell 1, so that the water outlet 103 of the water inlet shell 1 can communicate with the cleaning chamber 111 in one position, and can also use the second mounting plate 32 to connect to the cleaning chamber 110 of the cleaning machine 100 in another position. Therefore, the water inlet assembly 120 is stably installed in the cleaning chamber 110 of the cleaning machine 100 through the mounting bracket 3, which is beneficial to the compact structure.

[0067] Please continue reading. Figure 3 , Figure 4 and Figure 5 Optionally, the cleaning chamber 110 also includes a connecting column 113, which is located on two adjacent sides of the cleaning chamber 110, and the second mounting plate 32 is connected to the connecting column 113.

[0068] It is understandable that by placing the connecting post 113 on the bottom wall of the cleaning chamber 110, the water inlet shell 1 can fit against the side wall of the cleaning chamber 110, so that the water outlet 103 of the water inlet shell 1 can be located inside the mounting hole 112.

[0069] Furthermore, in the cleaning machine 100 provided in this application embodiment, the first mounting plate 31 and the second mounting plate 32 of the mounting frame 3 are respectively connected to two adjacent sides of the cleaning chamber 110, which is beneficial to the compactness of the structure.

[0070] Optionally, the connecting post 113 is provided with a first connecting hole 114, and the second mounting plate 32 is provided with a second connecting hole 301. After the second connecting hole 301 of the second mounting plate 32 is engaged with the first connecting hole 114 of the connecting post 113, the second mounting plate 32 and the connecting post 113 can be fixed by a threaded connector.

[0071] Optionally, there are multiple connecting columns 113, and the cleaning chamber 110 also includes a support plate 115 connecting two adjacent connecting columns 113. It is understood that the support plate 115 can increase the strength of the connecting column 113, which helps to prevent the connecting column 113 from deforming, thereby facilitating the connection of the second mounting plate 32 to the connecting column 113, and thus making it easier for the mounting frame 3 to be installed in the cleaning chamber 110.

[0072] It is understandable that the connection between the second mounting plate 32 and the connecting post 113 can also be a snap-fit ​​connection, adhesive bonding, welding, hot-melt connection, etc.

[0073] Please see Figure 6 In some embodiments, the mounting bracket 3 further includes a stiffener 33, which is disposed at the connection between the first mounting plate 31 and the second mounting plate 32, and the stiffener 33 is connected to the first mounting plate 31 and the second mounting plate 32 respectively.

[0074] In this way, the stiffener 33 can improve the strength of the mounting bracket 3 and its resistance to deformation, which is conducive to the stable connection between the water inlet shell 1 and the cleaning chamber 110, thereby improving the reliability of the water inlet assembly 120.

[0075] Optionally, there are two stiffening plates 33, with the connecting post 113 located between the two stiffening plates 33. In this way, the stiffening plates 33 can avoid the connecting post 113, thus preventing interference. For example, the stiffening plates 33 are located at the edge of the second mounting plate 32.

[0076] Optionally, the first mounting plate 31 is provided with a protruding reinforcing rib 311 on the side facing the cleaning chamber 110. The reinforcing rib 311 can improve the strength of the first mounting plate 31, thereby improving the deformation resistance of the mounting frame 3.

[0077] Optionally, the reinforcing rib 311 has a mesh structure, which can further improve the strength of the first mounting plate 31.

[0078] In some embodiments, the water inlet housing 1 is integrally formed. In this way, there are no seams in the water inlet housing 1, which can prevent the leakage of cleaning fluid.

[0079] Please see Figure 7 In some embodiments, the water inlet assembly 120 provided in this application further includes a water inlet pipe 2, which is connected to the water inlet shell 1 and communicates with the water inlet hole 102. The water inlet pipe 2 can be connected to a water delivery assembly to introduce cleaning fluid into the water inlet hole 102 and the cavity 101 of the water inlet shell 1. The water inlet pipe 2 and the water inlet shell 1 are integrally formed, thus eliminating the connection seam between them and preventing cleaning fluid leakage.

[0080] Optionally, the end of the water inlet pipe 2 away from the water inlet hole 102 is provided with an annular protrusion. This annular protrusion can be interference-fitted with the water supply pipe of the water supply assembly, so that the water supply pipe is not easy to fall off and can improve the stability of the connection between the water inlet pipe 2 and the water supply pipe.

[0081] Optionally, the water inlet assembly 120 provided in this application embodiment further includes a support block 5, which is connected to the water inlet pipe 2 and the first mounting plate 31 respectively. The support block 5 can support the water inlet pipe 2, thereby improving the strength of the water inlet pipe 2 and helping to prevent the water inlet pipe 2 from deforming.

[0082] The support block 5 may have a hollow hole 501, which can reduce the weight of the water inlet assembly 120.

[0083] Please continue reading. Figure 7 In some embodiments, the water inlet shell 1 is a cylindrical structure with an opening at one end, the water outlet 103 is disposed at one end of the water inlet shell 1 and forms the opening, and the water inlet 102 is disposed on the peripheral wall of the water inlet shell 1, that is, the water inlet pipe 2 is disposed on the peripheral wall of the water inlet shell 1.

[0084] It is understandable that, provided that the lowest point of the water inlet hole 102 is higher than the lowest point of the water outlet hole 103, the water inlet pipe 2 and the water inlet hole 102 can be set at multiple positions around the water inlet shell 1.

[0085] In this way, the extension direction of the water inlet hole 102 is different from that of the water outlet hole 103. That is, the extension direction of the water inlet hole 102 intersects with that of the water outlet hole 103. The cleaning fluid splashed into the cavity 101 from the water outlet hole 103 is less likely to enter the water inlet hole 102, which helps to prevent the cleaning fluid from flowing back.

[0086] Please continue reading. Figure 7 and combined Figure 8 In some embodiments, the water inlet shell 1 is a cylindrical or conical structure. In this way, the inner circumferential surface of the water inlet shell 1 is a cylindrical or conical surface with an arc. The cleaning liquid splashed onto the inner circumferential surface of the water inlet shell 1 can flow along the arc direction, which is conducive to the return of the cleaning liquid splashed onto the inner circumferential surface of the water inlet shell 1 to the bottom.

[0087] Optionally, the water inlet shell 1 has a conical structure, and the radial dimension of the cavity 101 gradually increases along the direction close to the opening. In this way, the cavity 101 is a conical cavity, and the lowest point of the end of the cavity 101 away from the opening is higher than the lowest point of the end of the cavity 101 close to the opening. The cleaning fluid in the cavity 101 can flow out smoothly from the water outlet 103 without accumulating in the cavity 101, which helps to prevent the cleaning fluid from flowing back.

[0088] Optionally, the water inlet shell 1 has a cylindrical structure, and the thickness of the peripheral wall of the water inlet shell 1 gradually decreases along the direction close to the opening. Similarly, the cavity 101 can be a conical cavity, and the lowest point of the cavity 101 away from the opening is higher than the lowest point of the cavity 101 close to the opening. The cleaning fluid in the cavity 101 can flow smoothly out from the water outlet 103 and will not accumulate in the cavity 101, thereby helping to prevent the cleaning fluid from flowing back in.

[0089] Please continue reading. Figure 7 and Figure 8 In some embodiments, the water inlet assembly 120 provided in this application also includes a sealing ring 4. The sealing ring 4 surrounds the outer periphery of the water inlet shell 1 and is located close to the opening. The sealing ring 4 is used to be located at the connection between the water outlet 103 and the cleaning chamber 111.

[0090] Optionally, the sealing ring 4 can be made of silicone.

[0091] In this way, the sealing ring 4 can seal the connection between the water outlet 103 and the cleaning chamber 111, which helps to prevent the cleaning fluid from leaking.

[0092] Please see Figure 8 and Figure 9 In some embodiments, the first mounting plate 31 surrounds the outer periphery of the water inlet shell 1 and is disposed near the opening, and the sealing ring 4 is located on the side of the first mounting plate 31 near the opening.

[0093] The sealing ring 4 includes a first sealing part 41 and a second sealing part 42. The first sealing part 41 is attached to the outer peripheral surface of the water inlet shell 1, and the second sealing part 42 is attached to the side surface of the first mounting plate 31 near the opening.

[0094] In this way, the sealing ring 4 can achieve two seals through the first sealing part 41 and the second sealing part 42, which helps to improve the sealing effect.

[0095] Optionally, the first mounting plate 31 is provided with a sealing groove 302 on the side facing the cleaning chamber 110, and the second sealing part 42 can be embedded in the sealing groove 302, thereby improving the sealing effect.

[0096] In addition, the hollow hole 501 of the support block 5 can communicate with the sealing groove 302, and part of the second sealing part 42 can extend into the hollow hole 501, so that the second sealing part 42 can be limited.

[0097] For example, the perforation 501 penetrates the bottom wall of the sealing groove 302.

[0098] The above are merely specific embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
