Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically a spray device and cleaning machine that facilitates rinsing. 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 rotating water spray mechanisms to spray and clean baby products from both above and below. The spray jets, with a certain water pressure, wash away dirt from the surface of the baby products. However, most baby bottles in existing cleaning machines are placed vertically, meaning that the spray jets can only clean the top and bottom of the baby products. The bottle body is not directly sprayed and rinsed, resulting in incomplete cleaning. Before cleaning, the bottle body usually retains grease, milk residue, dust, and other mixtures that have adhered to it from human contact. If not thoroughly cleaned over time, dirt will remain on the outside of the bottle, which will then contaminate and affect other baby products stored and sterilized together.

[0004] To address the above shortcomings, we need to develop a spray device and cleaning machine that is easy to rinse to meet the needs of a wide range of users. Utility Model Content

[0005] Regarding the aforementioned problem that existing cleaning machines using vertical spray jets can only clean the top and bottom ends of baby care products, resulting in insufficient cleaning, the technical solution adopted by this utility model is as follows: A spray device for easy rinsing includes a water pump assembly installed inside a cleaning machine, a spray pipe installed on the water pump assembly for spray cleaning, and a rotating spray arm hinged to the spray pipe. The rotating spray arm can rotate around the spray pipe in a circumferential direction. The rotating spray arm includes an upper spray arm and a lower spray arm located at opposite ends of the axial direction of the spray pipe. The upper spray arm has a first water outlet facing the lower spray arm, and the lower spray arm has a second water outlet facing the upper spray arm. The spray pipe has a third water outlet between the upper spray arm and the lower spray arm.

[0006] As described above, a spray device for easy rinsing is provided, wherein the spray pipe is provided with a number of segmented branch pipes arranged sequentially along the axial direction, and adjacent segmented branch pipes are coaxially arranged.

The first branch pipe section has a fourth water outlet at the position corresponding to the installation of the lower spray arm. The fourth water outlet is connected to the second water outlet via the water path of the lower spray arm.

[0008] As described above, a spray device for easy rinsing includes a water circuit segmented branch pipe comprising a second branch pipe segment installed at the extended end of the first branch pipe segment, and a third outlet located at the extended end of the second branch pipe segment away from the first branch pipe segment.

[0009] As described above, a spray device for easy rinsing includes a water circuit segmented branch pipe comprising a third branch pipe segment installed at the extended end of the second branch pipe segment. A sealing pipe head is installed at the extended end of the third branch pipe segment away from the second branch pipe segment. The upper spray arm is installed on the outer wall of the sealing pipe head. The sealing pipe head has a fifth water outlet at the position corresponding to the installation of the upper spray arm. The fifth water outlet is connected to the first water outlet via the water circuit of the upper spray arm.

[0010] As described above, in a spray device for easy rinsing, an auxiliary support for enhancing connection stability is installed between the second branch pipe section and the third branch pipe section. The lower stabilizing part of the auxiliary support is installed on the outer side wall of the second branch pipe section, and the upper stabilizing part of the auxiliary support is installed on the outer side wall of the third branch pipe section. The auxiliary support adopts a hollow structure with several through holes.

[0011] As described above, a spray device for easy rinsing has a stepped pipe section on the outside of the spray pipe for easy external assembly. The stepped pipe section is located at the position of the first branch pipe section near the second branch pipe section, the position of the second branch pipe section near the third branch pipe section, and the middle position of the third branch pipe section.

[0012] As described above, a spray device for easy rinsing includes a pump assembly comprising a pump unit for connecting to an external water tank, a filter unit for collecting and filtering wastewater backflow, and a valve unit for controlling wastewater discharge. The filter unit is located at the input end of the pump unit, and the spray pipe is installed at the output end of the pump unit.

[0013] As described above, in a spray device that facilitates rinsing, the valve body is connected to the drain port of the filter section, and the filter section has a filter screen structure located near the input end of the pump section.

[0014] A cleaning machine includes a body, a cleaning chamber located inside the body, and a water tank for supplying cleaning water.

[0020] Figure 5 This is a schematic diagram of the structure of a spray device and cleaning machine that facilitates rinsing according to the present invention. Detailed Implementation

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1: like Figures 1 to 3 The spray device shown includes a water pump assembly 1 installed inside the cleaning machine, a spray pipe 2 installed in the water pump assembly 1 for spray cleaning, and a rotating spray arm 3 hinged to the spray pipe 2. The rotating spray arm 3 can rotate around the spray pipe 2 in a circumferential direction. The rotating spray arm 3 includes an upper spray arm 31 and a lower spray arm 32 located at the two ends of the axial direction of the spray pipe 2, respectively. The upper spray arm 31 has a first water outlet 311 facing the lower spray arm 32, and the lower spray arm 32 has a second water outlet 321 facing the upper spray arm 31. The spray pipe 2 has a third water outlet 221 between the upper spray arm 31 and the lower spray arm 32.

[0023] Specifically, in this embodiment, the water pump assembly 1 is connected to the water tank of the cleaning machine to provide spray rinsing water with a certain water pressure to the spray device. The water pump assembly 1 is preferably installed near the bottom of the cleaning machine. The spray pipe 2 is a water pipe used by the water pump assembly 1 to supply water to the designated spray position. The spray pipe 2 is installed vertically from the water pump assembly 1 relative to the cleaning machine from bottom to top. The rotating spray arm 3 is a straight-handled rotating arm installed on the spray pipe 2 for implementing rotating spray rinsing. The upper spray arm 31 is installed near the top of the spray pipe 2 in the axial direction, and the lower spray arm 32 is installed near the bottom of the spray pipe 2 in the axial direction. The internal water passage of the spray pipe 2... The structure is connected to the first water outlet 311 of the upper spray arm 31 and the second water outlet 321 of the lower spray arm 32. The third water outlet 221 is located between the upper spray arm 31 and the lower spray arm 32. The third water outlet 221 is arranged circumferentially around the outer wall of the spray pipe 2, forming a multi-outlet water outlet structure that can spray and rinse in a circumferential direction. When in use, the water pump assembly 1 draws water from the water tank of the cleaning machine and pressurizes it to supply the spray pipe 2. The spray water flows through the internal water passage structure of the spray pipe 2 to the first water outlet 311, the second water outlet 321 and the third water outlet 221 respectively to achieve the effect of comprehensive spray cleaning of mother and baby products.

[0024] Furthermore, in some embodiments, such as Figures 1 to 3 as well as Figure 5 As shown, the rotating spray arm 3 extends symmetrically to both sides from the hinged installation position to form a spray arm structure of the same length. The first water outlet 311 or the second water outlet 321 is located on the extended spray arm structure. This spray arm structure covers a wider spray rinsing range and further improves the rinsing effect.

[0025] Example 2: like Figure 4 The spray device shown is easy to rinse. The water pump assembly 1 includes a pump unit 11, a filter unit 12 for collecting and filtering wastewater, and a valve body 13 for controlling wastewater discharge. The filter unit 12 is located at the input end of the pump unit 11, and the spray pipe 2 is installed at the output end of the pump unit 11. The valve body 13 is connected to the drain port 121 of the filter unit 12. The filter unit 12 is provided with a filter screen structure 122 near the input end of the pump unit 11. The wastewater generated by the spray rinsing flows down to the water inlet 123 of the filter unit 12. After being filtered by the filter screen structure 122 of the filter unit 12, it is pumped by the pump unit 11 to the spray pipe 2 for spraying. The dirt that cannot be filtered is discharged to the outside from the drain port 121 through the valve body 13.

[0026] Example 3: like Figures 1 to 3The spray device shown is easy to rinse. The spray pipe 2 is arranged with several segmented branch pipes along the axial direction. The adjacent segmented branch pipes are coaxially arranged. The adjacent segmented branch pipes are preferably integrally formed, but they can also be connected to each other by a detachable sleeve structure. The integrally formed structure can increase the structural stability of the spray device, improve the intensity of water pressure spraying, and reduce leakage and pressure loss at the connection points. The detachable sleeve structure makes it convenient for users to open the cleaning machine for internal cleaning and facilitates regular cleaning.

[0027] Furthermore, the water circuit segmented branch pipe includes a first branch pipe section 21 located near the water pump assembly 1. The first branch pipe section 21 is used to hinge the installation of the lower spray arm 32. The lower spray arm 32 is installed at the extended end of the first branch pipe section 21 away from the water pump assembly 1. The first branch pipe section 21 has a fourth water outlet 211 at the position corresponding to the installation of the lower spray arm 32. The fourth water outlet 211 is connected to the second water outlet 321 through the water circuit of the lower spray arm 32. During rinsing, the spray water is transported to the second water outlet 321 through the fourth water outlet 211 and sprayed out. The fourth water outlet 211 is arranged circumferentially around the outer wall of the first branch pipe section 21, forming a multi-outlet water outlet structure that can transport water in the circumferential direction. This facilitates the continuous water supply through the fourth water outlet 211 when the lower spray arm 32 rotates. The lower spray arm 32 has a hollow sleeve structure for wrapping around the fourth water outlet 211, so as to reduce leakage and pressure loss at the connection position when sleeved on the outer wall of the first branch pipe section 21.

[0028] Furthermore, the water circuit segmented branch pipe includes a second branch pipe section 22 installed at the extended end of the first branch pipe section 21. The second branch pipe section 22 is used to lengthen the middle length of the spray pipe 2 so that the spray pipe 2 can adapt to the inner height of the cleaning chamber 5 of the cleaning machine. The third outlet 221 is located at the extended end of the second branch pipe section 22 away from the first branch pipe section 21, preferably at a position close to the middle of the inner height of the cleaning chamber 5.

[0029] Furthermore, the water circuit segmented branch pipe includes a third branch pipe section 23 installed at the extended end of the second branch pipe section 22. The third branch pipe section 23 is used to lengthen the middle length of the spray pipe 2 so that the spray pipe 2 can adapt to the height of the inner cavity of the cleaning chamber 5 of the cleaning machine. A sealing pipe head 24 is installed at the extended end of the third branch pipe section 23 away from the second branch pipe section 22. The sealing pipe head 24 is used to hinge the upper spray arm 31 and restrict the spray pipe 2 to the top position of the cleaning chamber 5. The upper spray arm 31 is installed on the outer wall of the sealing pipe head 24. The sealing pipe head 24 has a fifth water outlet 24 at the position corresponding to the installation of the upper spray arm 31. 1. The fifth outlet 241 is connected to the first outlet 311 via the water passage of the upper spray arm 31. During rinsing, the spray water is transported to the first outlet 311 through the fifth outlet 241 and sprayed out. The fifth outlet 241 is arranged circumferentially around the outer wall of the sealing pipe head 24 to form a multi-outlet water outlet structure that can transport water in the circumferential direction. This allows the upper spray arm 31 to supply water continuously through the fifth outlet 241 when it rotates. The upper spray arm 31 has a hollow sleeve structure for wrapping around the fifth outlet 241 to reduce leakage and pressure relief at the connection point when it is sleeved on the outer wall of the sealing pipe head 24.

[0030] Furthermore, an auxiliary support 25 for enhancing connection stability is installed between the second branch pipe section 22 and the third branch pipe section 23. The third outlet 221 is located within the installation range of the auxiliary support 25. The lower stabilizing part 251 of the auxiliary support 25 is installed on the outer wall of the second branch pipe section 22, and the upper stabilizing part 252 of the auxiliary support 25 is installed on the outer wall of the third branch pipe section 23. The auxiliary support 25 adopts a hollow structure with several through holes, which can prevent flushing residue from blocking and clogging the third outlet 221. During washing, the spray water is sprayed out from the third outlet 221, passing through the hollow structure with several through holes and being dispersed and sprayed onto the baby products to be cleaned, which can disperse the spray water column and further improve the coverage of the spray. The upper stabilizing part 252 and the lower stabilizing part 251 of the auxiliary support 25 strengthen the connection stability between the second branch pipe section 22 and the third branch pipe section 23, and can maintain good structural stability even when using high-level spray, reducing the shaking, loosening and detachment of the connection position caused by high-level spray.

[0031] Furthermore, the outer side of the spray pipe 2 has a pipe segment step 26 for easy external assembly. The pipe segment step 26 is a limiting structure for the detachable sleeve structure between adjacent branch pipe segments. It can also be used to limit the installation height of the shelf inside the cleaning chamber 5. After the adjacent branch pipe segments are sleeved and installed, the insertion distance and position can be limited after being inserted into the position of the pipe segment step 26. The pipe segment step 26 is located at the position of the first branch pipe segment 21 near the second branch pipe segment 22, the position of the second branch pipe segment 22 near the third branch pipe segment 23, and the middle position of the third branch pipe segment 23. The outer diameter of the branch pipe segment on one side of the pipe segment step 26 is larger than the outer diameter of the branch pipe segment on the other side, forming a pipe segment step 26 similar to a right angle corner through the difference in outer diameter.

[0032] Example 4: like Figures 1 to 5 The washing machine shown includes a body 4, a washing chamber 5 located inside the body 4, and a water tank 6 for supplying water for washing. The washing chamber 5 is equipped with the spray device. A water pump assembly 1 is installed at the bottom of the washing chamber 5, and a spray pipe 2 is installed at the top of the washing chamber 5, away from the top of the water pump assembly 1. The water pump assembly 1 is connected to the water tank 6. The body 4 is the outer casing of the washing machine and its electrical control unit. The washing chamber 5 is an inner chamber structure located inside the body 4 for placing and washing baby care products. The water pump assembly 1 of the spray device is installed at the bottom outside the washing chamber 5 and is connected to the water tank 6 of the washing machine. The spray pipe 2 extends into the washing chamber 5 from the bottom. The interior of the cleaning chamber 5 is vertically oriented, reaching the top of the cleaning chamber 5. The upper spray arm 31 is installed inside the cleaning chamber 5 near the top of the cleaning chamber 5, with its first outlet 311 facing the bottom of the cleaning chamber 5. The lower spray arm is installed inside the cleaning chamber 5 near the bottom of the cleaning chamber 5, with its second outlet 321 facing the top of the cleaning chamber 5. In use, the water pump assembly 1 draws water from the water tank 6 of the cleaning machine and pressurizes it to supply the spray pipe 2. The spray water flows through the internal water passage structure of the spray pipe 2 to the first outlet 311, the second outlet 321 and the third outlet 221 respectively to achieve the effect of comprehensive spray cleaning of mother and baby products.
