Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically a side-flow water spraying device and a cleaning machine. Background Technology

[0002] In the daily life of mothers and infants, baby bottles, nipples, breast pump suction cups, and other baby supplies need to be cleaned frequently. The traditional method is to wash them by hand repeatedly with water in a sink. Since hand washing is tiring, cleaning machines suitable for baby supplies quickly appeared on the market. Baby supplies can be placed in the cleaning machine for cleaning, helping families to free themselves from the cleaning process, reducing fatigue and saving more time to care for infants and young children.

[0003] Existing cleaning machines typically use a spray system that delivers water up and down through the center of the cleaning chamber. Because this water delivery method is located in the center of the space, it is relatively easy to cover the cleaning area of ​​baby and maternity products placed around the center. However, this method causes the water channel structure of the spray system to occupy the space in the center of the cleaning chamber, preventing baby and maternity products from being placed in the center. The spray system indirectly occupies the space for placing baby and maternity products, affecting the overall capacity of the cleaning machine.

[0004] To address the above shortcomings, we need to develop a side-flow water spraying device and cleaning machine to meet the needs of a wide range of users. Utility Model Content

[0005] Regarding the aforementioned problem that the water circuit structure of existing spray devices occupies space in the middle of the cleaning chamber and affects the placement and capacity of the cleaning machine, the technical solution adopted by this utility model to solve this problem is:

[0006] A side-flow water spraying device includes a cleaning chamber housing with an internal cleaning cavity, a water pump assembly mounted on the cleaning chamber housing, and a cleaning spraying mechanism mounted on the water pump assembly. The cleaning spraying mechanism includes a first branch pipe section and a second branch pipe section. The first branch pipe section extends into the cleaning cavity from the bottom of the cleaning chamber housing, and the second branch pipe section extends into the cleaning cavity from the top of the cleaning chamber housing via the outside of the cleaning chamber housing. Rotating spray arms for spraying cleaning are respectively hinged to the outside of the pipe body of the first branch pipe section and the outside of the pipe body of the second branch pipe section. The rotating spray arms can rotate circumferentially around the outside of the pipe body.

[0007] As described above, in a side-flow water spraying device, the cleaning chamber housing includes an upper housing and a lower housing that are detachable from each other. The upper housing and the lower housing each have a junction structure for assembly and closing. A pipe section clearance groove extends from the middle of the top side of the upper housing toward the junction structure and is recessed toward the cleaning chamber.

[0008] As described above, in a side-flowing spray device, the upper housing is provided with an upper pipe section interface at a position near the pipe section clearance groove in the junction structure, the lower housing is provided with a lower pipe section interface at a position near the pipe section clearance groove in the junction structure, the water pump assembly is connected to the lower pipe section interface via a water pipe, the lower pipe section interface is connected to the upper pipe section interface within the junction structure, and the upper pipe section interface is connected to the second branch pipe section via a water pipe.

[0009] As described above, in a side-flowing water spraying device, the upper housing includes a pipe groove cover adapted to cover the void groove of the pipe section, and the pipe groove cover and the void groove of the pipe section are connected by a snap-fit ​​connection.

[0010] As described above, in a side-flow water spraying device, the pipe section clearance groove has a vertically arranged first pipe groove side e and second pipe groove side f. The first pipe groove side e and the second pipe groove side f form a pipe groove angle structure that gradually opens from the middle of the top side of the upper shell toward the extension direction of the pipe section clearance groove. The opening angle C of the pipe groove angle structure is an acute angle.

[0011] In the lateral water supply spray device described above, the opening angle C of the pipe groove angle structure is between 10 degrees and 15 degrees.

[0012] As described above, in a side-flowing water spraying device, the pipe section has a horizontally arranged third pipe groove bottom surface g, and the first pipe groove side surface e and the second pipe groove side surface f are respectively perpendicular to the third pipe groove bottom surface g.

[0013] As described above, in a side-flowing water spraying device, the rotating spray arm includes a lower spray arm installed on a first branch pipe section and an upper spray arm installed on a second branch pipe section. The lower spray arm has a first water outlet facing the upper spray arm, and the upper spray arm has a second water outlet facing the lower spray arm.

[0014] As described above, in a side-flow water spraying device, the pump assembly includes a pump section for connecting to an external water tank, a filter section for collecting and filtering wastewater backflow, and a valve body section for controlling wastewater discharge. The filter section is located at the input end of the pump section, and the first branch pipe section and the second branch pipe section are respectively installed at the output end of the pump section.

[0015] A cleaning machine includes a body, a water tank mounted on the body for supplying water for cleaning, a spray device installed on the body, a cleaning chamber housing located inside the body, and a water pump assembly connected to the water tank.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention employs a first branch pipe section and a second branch pipe section that extend into the cleaning chamber from the top and bottom sides of the cleaning chamber shell, respectively. The second branch pipe section extends from the outside of the cleaning chamber shell to the top of the cleaning chamber shell, eliminating the need to pass through the middle of the cleaning chamber and thus not occupying the internal space of the cleaning chamber shell. This allows more space inside the cleaning chamber shell to be used for placing baby and maternity products to be cleaned. The first and second branch pipe sections extend from the top and bottom sides of the cleaning chamber shell, respectively, and when used in conjunction with the rotating spray arm, they create an up-and-down spray rinsing effect, making the baby and maternity products cleaner. The rotating spray arm can rotate circumferentially around the outside of the pipe body to cover a wider spray rinsing range, further improving the rinsing spray effect. Attached Figure Description

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1:

[0027] like Figures 1 to 6The illustrated side-flow water spraying device and cleaning machine include a cleaning chamber housing 1 with an internal cleaning cavity 14, a water pump assembly 2 mounted on the cleaning chamber housing 1, and a cleaning spraying mechanism 3 mounted on the water pump assembly 2. The cleaning spraying mechanism 3 includes a first branch pipe section 31 and a second branch pipe section 32. The first branch pipe section 31 extends into the cleaning cavity 14 from the bottom of the cleaning chamber housing 1, and the second branch pipe section 32 extends into the cleaning cavity 14 from the top of the cleaning chamber housing 1 via the outside of the cleaning chamber housing 1. Rotating spray arms 33 for spray cleaning are respectively hinged to the outside of the pipe body of the first branch pipe section 31 and the outside of the pipe body of the second branch pipe section 32. The rotating spray arms 33 can rotate around the outside of the pipe body in a circumferential direction.

[0028] Specifically, in this embodiment, the water pump assembly 2 is connected to the water tank 5 of the cleaning machine to provide spray rinsing water with a certain water pressure to the spray device. The water pump assembly 2 is preferably installed near the bottom of the cleaning chamber shell 1. The first branch pipe section 31 and the second branch pipe section 32 are water pipes used by the water pump assembly 2 to supply water to the designated spray position. The rotating spray arm 33 is a straight-handled rotary arm used to perform rotating spray rinsing. The rotating spray arm 33 is located at the first branch pipe section 31 at the bottom of the cleaning chamber shell 1 and the second branch pipe section 32 at the top of the cleaning chamber shell 1, and rotates towards the inside of the cleaning chamber 14 for spray rinsing. More specifically, the first branch pipe section 31 has a first branch pipe outlet 311 at the position corresponding to the installation of the rotating spray arm 33, and the second branch pipe section 32 has a first branch pipe outlet 311 at the position corresponding to the installation of the rotating spray arm 33. The second branch pipe outlet 321 is provided at the location. When in use, the water pump assembly 2 draws water from the water tank 5 of the cleaning machine and pressurizes it to supply the first branch pipe section 31 and the second branch pipe section 32 respectively. The spray water flows through the internal water passage structure of the first branch pipe section 31 and the second branch pipe section 32 to the first branch pipe outlet 311 and the second branch pipe outlet 321 respectively. The second branch pipe section 32 extends into the cleaning chamber 14 from the top of the cleaning chamber shell 1 through the outside of the cleaning chamber shell 1. The spray water is delivered to the rotating spray arm 33 located in the first branch pipe section 31 through the first branch pipe outlet 311 and sprayed out for rinsing. The spray water is delivered to the rotating spray arm 33 located in the second branch pipe section 32 through the second branch pipe outlet 321 and sprayed out for rinsing, so as to achieve the effect of comprehensive spray cleaning of mother and baby products.

[0029] Furthermore, in some embodiments, the cleaning chamber housing 1 includes a detachable upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 each have a junction structure 13 for assembly and fitting. The top side of the upper housing 11 extends from the middle toward the junction structure 13 to form a pipe section clearance groove 112 recessed toward the cleaning chamber 14. The detachable upper housing 11 and the lower housing 12 facilitate the customer to open and place the baby and maternity utensils to be cleaned. The junction structure 13 is located at the middle of the vertical height of the cleaning chamber housing 1 and forms a horizontal junction boundary. The junction structure 13 can adopt an inverted structure, a snap-fit ​​structure, friction installation, etc. to ensure the stable assembly position of the upper housing 11 and the lower housing 12. The pipe section clearance groove 112 is used to prevent the installation of the second branch pipe section 32 from being exposed on the surface of the cleaning chamber housing 1. The water passage structure of the second branch pipe section 32 connected to the water pump assembly 2 is via the pipe section clearance groove 112, making the overall appearance more aesthetically pleasing and reducing the space occupied.

[0030] Furthermore, in some embodiments, the upper housing 11 is provided with an upper pipe section interface 111 near the pipe section clearance groove 112 in the confluence structure 13, and the lower housing 12 is provided with a lower pipe section interface 121 near the pipe section clearance groove 112 in the confluence structure 13. The water pump assembly 2 is connected to the lower pipe section interface 121 through a water pipe. The lower pipe section interface 121 is connected to the upper pipe section interface 111 in the confluence structure 13. The upper pipe section interface 111 is connected to the second branch pipe section 32 through a water pipe. The water passage structure of the second branch pipe section 32, which is separately provided in the upper housing 11 and the lower housing 12, is smoothly connected through the upper pipe section interface 111 and the lower pipe section interface 121, forming a water passage structure that smoothly connects the water pump assembly 2 from the bottom of the cleaning chamber housing 1 to the top of the cleaning chamber housing 1 via the outside of the cleaning chamber housing 1.

[0031] Furthermore, in some embodiments, the upper housing 11 includes a pipe groove cover 15 adapted to cover the pipe section clearance groove 112. The pipe groove cover 15 and the pipe section clearance groove 112 are connected by a snap-fit. The shape of the pipe groove cover 15 matches the corner shape of the pipe section clearance groove 112. After installation, the pipe section clearance groove 112 is not exposed outside the cleaning chamber housing 1. The pipe groove cover 15 can also cover the water passage structure of the second branch pipe section 32 that runs through the pipe section clearance groove 112, making the exterior of the cleaning chamber housing 1 more complete and aesthetically pleasing. It can also prevent the water passage structure of the pipe section clearance groove 112 from being damaged by external influences.

[0032] Furthermore, in some embodiments, the pipe section clearance groove 112 has a vertically arranged first pipe groove side 112e and second pipe groove side 112f. The first pipe groove side 112e and the second pipe groove side 112f form a pipe groove angle structure that gradually opens from the middle of the top side of the upper shell 11 toward the extension direction of the pipe section clearance groove 112. The opening angle C of the pipe groove angle structure is an acute angle. The first pipe groove side 112e and the second pipe groove side 112f are the vertical sidewalls inside the pipe section clearance groove 112. The pipe groove angle structure can adapt to water pipe structures with straight connections and corner transitions. Moreover, such a structure is easier to process and form. The opening angle C of the pipe groove angle structure is an acute angle. The opening angle C is preferably an angle adjustment between 10 degrees and 15 degrees. If the opening angle C is too small, it is not convenient to install water pipe structures. If the opening angle C is too large, it occupies too much space in the upper shell 11 and affects the actual use effect.

[0033] Furthermore, in some embodiments, the pipe section clearance groove 112 has a horizontally arranged third pipe groove bottom surface 112g, and the first pipe groove side surface 112e and the second pipe groove side surface 112f are respectively perpendicular to the third pipe groove bottom surface 112g. Such a structure is easier to process and form, reduces the requirements for bending or transition of waterway structure pipes, and is easier to assemble and form.

[0034] Furthermore, in some embodiments, the rotating spray arm 33 includes a lower spray arm 331 installed on the first branch pipe section 31 and an upper spray arm 333 installed on the second branch pipe section 32. The lower spray arm 331 has a first water outlet 332 facing the upper spray arm 333, and the upper spray arm 333 has a second water outlet 334 facing the lower spray arm 331. The spray water flows through the internal water passage structure of the first branch pipe section 31 and the second branch pipe section 32 to the first branch pipe outlet 311 and the second branch pipe outlet, respectively. The second branch pipe section 32 extends into the cleaning chamber 14 from the top of the cleaning chamber housing 1 via the outside of the cleaning chamber housing 1. Spray water is delivered to the lower spray arm 331 located in the first branch pipe section 31 via the first branch pipe outlet 311 and sprayed out for rinsing via the first outlet 332. Spray water is delivered to the upper spray arm 333 located in the second branch pipe section 32 via the second branch pipe outlet 321 and sprayed out for rinsing via the second outlet 334, so as to achieve the effect of comprehensive spray cleaning of mother and baby products.

[0035] Furthermore, in some embodiments, such as Figures 5 to 6 As shown, the rotating spray arm 33 extends symmetrically to both sides from the hinged installation position to form a spray arm structure of the same length. The first water outlet 332 or the second water outlet 334 is located on the extended spray arm structure. This spray arm structure covers a wider spray rinsing range and further improves the rinsing effect.

[0036] Furthermore, in some embodiments, the pump assembly 2 includes a pump section 21 for connecting to an external water tank, a filter section 22 for collecting and filtering wastewater backflow, and a valve body section 23 for controlling wastewater discharge. The filter section 22 is located at the input end of the pump section 21, and the first branch pipe section 31 and the second branch pipe section 32 are respectively installed at the output end of the pump section 21. More specifically, the valve body section 23 is connected to the drain port 221 of the filter section 22. The filter section 22 is provided with a filter screen structure 222 near the input end of the pump section 21. Wastewater generated by spraying and rinsing flows down into the water inlet 223 of the filter section 22. After being filtered by the filter screen structure 222 of the filter section 22, it is pumped again by the pump section 21 to the first branch pipe section 31 and the second branch pipe section 32 for use. The dirt that cannot be filtered is discharged to the outside from the drain port 221 through the valve body section 23.

[0037] Example 2:

[0038] like Figures 1 to 7 The cleaning machine shown includes a body 4 and a water tank 5 installed on the body for supplying water for cleaning. The body 4 is equipped with the spray device. A cleaning chamber shell 1 is located inside the body 4. A water pump assembly 2 is connected to the water tank 5. The body 4 is the outer casing of the cleaning machine and its electrical control unit. The water pump assembly 2 of the spray device is installed at the bottom of the outer side of the cleaning chamber shell 1 and is connected to the water tank 5 of the cleaning machine. A first branch pipe section 31 extends from the bottom of the cleaning chamber shell 1 into the interior of the cleaning chamber shell 1 and is located at the bottom of the cleaning chamber 14, where it sprays water through the lower spray arm 331. A second branch pipe section 32 extends from the bottom of the cleaning chamber shell 1 along the outer side of the cleaning chamber shell 1, through the lower pipe section interface 121 and the upper pipe section interface 32. Interface 111 and pipe section clearance groove 112 are connected to the top of the cleaning chamber shell 1 and extend into the interior of the cleaning chamber shell 1. Spraying is carried out at the top of the cleaning chamber 14 through the upper spray arm 333. When in use, the water pump assembly 2 draws water from the water tank 5 of the cleaning machine and pressurizes it to supply the first branch pipe section 31 and the second branch pipe section 32 respectively. The spray water is transported through the outlet 311 of the first branch pipe to the lower spray arm 331 located in the first branch pipe section 31 and sprayed out through the first outlet 332 for rinsing. The spray water is transported through the outlet 321 of the second branch pipe to the upper spray arm 333 located in the second branch pipe section 32 and sprayed out through the second outlet 334 for rinsing, so as to achieve the effect of comprehensive spray cleaning of mother and baby products.
