It should be noted that a nursing bottle generally includes a body 22, a nipple 24, and a milk cap. In cleaning a baby bottle using the baby bottle cleaning machine 10, the baby bottle is typically disassembled into the bottle body 22, the nipple 24 and the milk cap, and then the bottle body 22 and/or the nipple 24 and/or the milk cap are placed on the first shelf 12 for cleaning. It is to be understood that the above-described baby bottle washing machine 10 can wash cups similar in shape to the body 22 of a baby bottle, and that the above-described baby bottle washing machine 10 can also wash utensils similar in shape to a nipple 24 or a nipple cap, i.e., the above-described baby bottle washing machine 10 is not limited to washing a baby bottle, but can also wash cups similar in shape to the body 22 of a baby bottle and utensils similar in shape to the nipple 24 or the nipple cap.

In the present embodiment, the spray device includes a lower spray assembly 300 and an upper spray assembly 400. The lower spray assembly 300 is adapted to be disposed below the first rack 12. The upper spray assembly 400 is adapted to be disposed above the first shelf 12. In the above-described baby bottle washing machine 10, when the openings of the bottle bodies 22 and/or the nipples 24 and/or the milk caps are directed downward, the lower spray assemblies 300 spray water upward to wash the inner sides of the bottle bodies 22 and/or the nipples 24 and/or the milk caps, and the upper spray assemblies 400 spray water downward to wash the outer sides of the bottle bodies 22 and/or the nipples 24 and/or the milk caps; and when the openings of the bottle body 22 and/or the nipple 24 and/or the milk cap are directed upward, the lower spray assembly 300 sprays water upward, the outside of the bottle body 22 and/or the nipple 24 and/or the milk cap can be cleaned, and the upper spray assembly 400 sprays water downward, the inside of the bottle body 22 and/or the nipple 24 and/or the milk cap can be cleaned.

In the related art, when the milk bottle cleaning machine works, the spray column located below the milk bottle sprays water upwards, part of the water sprays upwards to directly clean the inner sides of the milk bottle and the accessories thereof, and part of the water enters the leaching cavity located above the milk bottle and then falls back downwards under the action of gravity to clean the outer sides of the milk bottle and the accessories thereof (it should be noted that a water inlet hole with a larger aperture and a spray hole with a smaller aperture are arranged below the leaching cavity, and the water sprayed from the spray column enters the leaching cavity through the water inlet hole and then is sprayed with Kong Huila). In practical application, it is found that the cleaning effect of the milk bottle cleaning machine in the related art needs to be improved, and the improvement of the spraying device of the milk bottle cleaning machine in the related art is one of the directions for improving the cleaning effect.

For this reason, in the embodiment of the present invention, a spray device in the related art is improved. In this embodiment, the spray device includes a hollow spray arm 410 for communicating with a water supply. A hollow spray arm 410 is rotatably connected to the housing and has an outlet opening 410a for cleaning the bottle. Specifically, in the present embodiment, the hollow spray arm 410 can be rotated by the water stream formed by the water discharged through the water outlet hole 410a. Thus, the rotation of the hollow spray arm 410 can be achieved without providing an additional driving mechanism.

It should be noted that, in the present embodiment, the upper spray assembly 400 includes the hollow spray arm 410, and the lower spray assembly 300 does not include the hollow spray arm 410. It is understood that in other embodiments, the lower spray assembly 300 may also include a hollow spray arm 410, while the upper spray assembly 400 does not include a hollow spray arm 410, and the upper spray assembly 400 may also include a hollow spray arm 410, while the lower spray assembly 300 also includes a hollow spray arm 410.

In the baby bottle washing machine 10, the hollow spray arm 410 is used for being communicated with a water supply device, so that the hollow spray arm 410 has a larger water pressure, and meanwhile, the hollow spray arm 410 can rotate, so that the hollow spray arm 410 has a larger washing range, and under the synergistic effect of the larger water pressure and the larger washing range, the baby bottle washing machine 10 has a better washing effect.

In the present embodiment, as shown in fig. 1 to 3, the baby bottle washing machine 10 further includes a connection ring 16. The connection ring 16 is rotatably provided on the housing. The hollow spray arm 410 is connected to the connection ring 16. Thus, it is very convenient to realize the rotation connection of the hollow spray arm 410 and the housing, so that one side of the hollow spray arm 410 close to the housing can be provided with a closed area 410c, the discharge flow is reduced, and the hollow spray arm 410 can have a larger water pressure.

In this embodiment, the housing has mounting posts 182, as shown in fig. 2-7. The attachment ring 16 is disposed on the mounting post 182 and is rotatable relative to the mounting post 182. Specifically, in the present embodiment, one end of the mounting post 182 is disposed on the housing, the other end is a free end, and the free end has a stopper 184 to limit the connection ring 16 from coming out of the free end. More specifically, in the present embodiment, the connection ring 16 can move along the length direction of the mounting post 182, so that the connection ring 16 has better mobility, reduced wear and easy installation. The corresponding position-limiting member 184 can limit the connection ring 16 from coming off the end of the mounting post 182 away from the housing, so that the connection ring 16 is stably mounted on the mounting post 182. It will be appreciated that in other embodiments, rotation of the attachment ring 16 relative to the mounting posts 182 may also be achieved when the inner peripheral wall of the attachment ring 16 has inserts, the mounting posts 182 have circumferentially extending slots, the inserts are inserted into the slots, and the inserts are slidably engaged with the slots.

In this embodiment, the attachment ring 16 is removably attached to the mounting post 182. In this way, the attachment ring 16 is very easily attached and detached. Specifically, in the present embodiment, as shown in fig. 7 and 8, the connection ring 16 includes two removably connected half rings 162. In this manner, it is very convenient to removably couple the coupling ring 16 to the mounting post 182, which in turn facilitates the rotatable coupling of the hollow spray arm 410 to the housing via the coupling ring 16, i.e., it is very convenient to mount the hollow spray arm 410. It is understood that in other embodiments, when the retaining member 184 is detachably connected to the mounting post 182, the connecting ring 16 can be detachably connected to the mounting post 182 by detaching the retaining member 184, and in this case, the connecting ring 16 does not include two detachably connected halves 162, but is an integral ring.

In the embodiment, each half ring 162 has a buckle 162a at one end and a slot 162b at the other end, and the buckle 162a of one half ring 162 is connected with the slot 162b of the other half ring 162. In this manner, it is very convenient for the two half rings 162 to be detachably connected. It is understood that in other embodiments, the two half rings 162 can be detachably connected by screwing, interference fit, etc.

In this embodiment, the hollow spray arm 410 is detachably connected to the housing. Thus, the hollow spray arm 410 is very convenient to disassemble and assemble. Specifically, in the present embodiment, the hollow spray arm 410 is detachably coupled to the connection ring 16. More specifically, in the present embodiment, the hollow spray arm 410 includes an arm body 412 and a mounting tube 414 provided to protrude on one side of the arm body 412. The outlet hole 410a is located on the arm 412. The mounting tube 414 is detachably sleeved outside the connection ring 16.

In the present embodiment, one of the connection ring 16 and the mounting tube 414 has a protrusion 164, and the other of the connection ring 16 and the mounting tube 414 has a groove 414a, and the protrusion 164 is inserted into the groove 414a. Thus, it is very convenient for the mounting tube 414 to be detachably sleeved outside the connection ring 16. Specifically, in this embodiment, the outer peripheral wall of the connection ring 16 has the projection 164 thereon, and the inner peripheral wall of the mounting tube 414 has the recess 414a thereon. It will be appreciated that in other embodiments, the ring 16 may have a recess 414a in the outer peripheral wall and a projection 164 in the inner peripheral wall of the mounting tube 414.

In the present embodiment, as shown in fig. 1, the lower spray assembly 300 has a spray post 310, and the spray post 310 is used to communicate with a water supply device. The upper spray assembly 400 has a hollow spray arm 410. The spray post 310 facilitates cleaning of the inside of the bottle 22 and/or nipple 24 and/or nipple cap which is more difficult to clean, while the hollow spray arm 410 provides for good cleaning of the outside of the bottle 22 and/or nipple 24 and/or nipple cap. With such a layout, the feeding bottle washing machine 10 has a better washing effect.

In this embodiment, the lower spray assembly 300 has a water inlet 300a, and the water inlet 300a communicates with the water spray post 310 and the water supply device. That is, in the present embodiment, the lower spray assembly 300 may be directly communicated with the water supply device. In this manner, a greater water pressure may be provided to lower spray assembly 300, and lower spray assembly 300 may be better suited for cleaning the inside of bottle 22 and/or nipple 24 and/or the milk cap.

In this embodiment, the spray device further includes a connection pipe 500. The connection pipe 500 communicates the water inlet 300a with the hollow nozzle arm 410. That is, in the present embodiment, the water supply device, the lower spray assembly 300, and the upper spray assembly 400 are sequentially communicated, so that the upper spray assembly 400 is indirectly communicated with the water supply device. The hollow spray arm 410 of the upper spray assembly 400 has a greater water pressure than the spray column 310 that sprays water into the spray chamber above the baby bottle (in which case the water pressure in the spray chamber is lower), and the water sprayed from the hollow spray arm 410 under a higher pressure can better clean the outside of the bottle body 22 and/or nipple 24 and/or the milk cap under its own weight. And the water supply device, the lower spray assembly 300 and the upper spray assembly 400 are communicated in sequence, and one water supply device can be adopted to simultaneously supply water to the lower spray assembly 300 and the upper spray assembly 400, so that the structure of the milk bottle cleaning machine 10 is simpler, and the volume is smaller. It is understood that in other embodiments, the baby bottle washing machine 10 may have two water supplies, one supplying water directly to the lower spray assembly 300 and the other supplying water directly to the upper spray assembly 400, and in this case, the connection pipe 500 may be omitted.

In the present embodiment, as shown in fig. 3, 6 and 7, and 9 and 10, one side of the hollow spray arm 410 has a mounting hole 410b. One end of the connection pipe 500 is inserted into the hollow spray arm 410 through the mounting hole 410b and is communicated with the hollow spray arm 410, and the other end of the connection pipe 500 is used for being communicated with a water supply device (indirectly communicated with the water supply device through the lower spray assembly 300). The hollow spray arm 410 is rotatable with respect to the connection pipe 500. In this manner, indirect communication of the hollow spray arm 410 with a water supply device is facilitated, and rotation of the hollow spray arm 410 is facilitated.

In the present embodiment, the region of the other side of the hollow spray arm 410 corresponding to the mounting hole 410b is a closed region 410c. Thus, when the connection pipe 500 supplies water to the hollow spray arm 410, the closed area 410c can effectively prevent the water from flowing out through the closed area 410c, so that the water can be ensured to flow into the hollow spray arm 410, and the hollow spray arm 410 can be ensured to have a larger water pressure, so that the baby bottle washing machine 10 has a better washing effect.

In the present embodiment, the closed region 410c protrudes toward a direction away from the mounting hole 410b, forming a protruding portion located outside the hollow nozzle arm 410 and an inner recessed portion located inside the hollow nozzle arm 410. So, be more convenient for connecting pipe 500 and cavity spray arm 410 to communicate, after cavity spray arm 410 (the interior concave part of cavity spray arm 410) pressed on the terminal surface 500b of the blind end of connecting pipe 500, can reduce the area of contact of cavity spray arm 410 and the blind end of connecting pipe 500 moreover to can reduce the friction, and then more do benefit to cavity spray arm 410 and rotate for connecting pipe 500.

In this embodiment, the end of the connection pipe 500 located inside the hollow spray arm 410 is a closed end, and the circumferential wall of the closed end has a water outlet 500a for communicating the connection pipe 500 and the hollow spray arm 410. The blind end of connecting pipe 500 can prevent effectively that rivers from unloading through the blind end and flowing, rivers can follow the circumference of connecting pipe 500 moreover and get into in the cavity spray arm 410, can also do benefit to in water gets into cavity spray arm 410 for the rotatory prerequisite of connecting pipe 500 at cavity spray arm 410, and then can ensure that cavity spray arm 410 has great water pressure.

In the present embodiment, the area corresponding to the mounting hole 410b on the other side of the hollow spray arm 410 is a closed area 410c, and one end of the connection pipe 500 located inside the hollow spray arm 410 is a closed end, and the circumferential wall of the closed end has a water outlet 500a for communicating the connection pipe 500 and the hollow spray arm 410. It is understood that in other embodiments, the other side of the hollow spray arm 410 corresponding to the mounting hole 410b may be a closed region 410c, or one end of the connection pipe 500 located inside the hollow spray arm 410 may be a closed end, and the circumferential wall of the closed end has a water outlet 500a for communicating the connection pipe 500 and the hollow spray arm 410.

In the present embodiment, end surface 500b of the closed end of connecting pipe 500 is tapered in the direction toward the closed end, that is, end surface 500b of the closed end of connecting pipe 500 has a structure with a large bottom and a small top. Thus, after the hollow spray arm 410 is pressed on the end surface 500b of the closed end of the connection pipe 500, the contact area between the hollow spray arm 410 and the closed end of the connection pipe 500 can be reduced, so that friction can be reduced, and the hollow spray arm 410 can rotate relative to the connection pipe 500.

Specifically, in the present embodiment, the end surface 500b of the closed end of the connection pipe 500 is a conical surface, so that the contact between the top of the end surface 500b of the closed end of the connection pipe 500 and the hollow spray arm 410 is point contact, and the friction is minimized. It is understood that in other embodiments, the end face 500b of the closed end of the connection tube 500 may be a circular table.

In the present embodiment, the closed region 410c protrudes toward a direction away from the mounting hole 410b, a protruding portion located outside the hollow nozzle arm 410 and an inner recessed portion located inside the hollow nozzle arm 410 are formed, and the end surface 500b of the closed end of the connection pipe 500 is tapered. It is understood that in other embodiments, the closed region 410c may be protruded away from the mounting hole 410b to form a protrusion outside the hollow nozzle arm 410 and an inner recess inside the hollow nozzle arm 410, or the end surface 500b of the closed end of the connection pipe 500 may be tapered.

In this embodiment, the hollow spray arm 410 has a guide tube 416 disposed around the mounting hole 410b, and the connection tube 500 is inserted into the guide tube 416. In this manner, the guide tube 416 can guide the insertion of the connection tube 500 into the mounting hole 410b, thereby facilitating the insertion of the connection tube 500 into the mounting hole 410b, that is, the assembly of the hollow spray arm 410 with the connection tube 500.

In the present embodiment, as shown in fig. 3, 4 and 11, the inner diameter of the connection ring 16 is larger than the outer diameter of the mounting post 182, and the inner circumferential wall of the connection ring 16 or the outer circumferential wall of the mounting post 182 is provided with a plurality of first protrusions 166 arranged in a dispersed manner. The inner diameter of the connecting ring 16 is larger than the outer diameter of the mounting post 182 to reduce friction and ensure smooth rotation of the connecting ring 16 relative to the mounting post 182, while the larger the gap between the inner peripheral wall of the connecting ring 16 and the outer peripheral wall of the mounting post 182, the more severe the flow discharge between the connecting ring 16 and the mounting post 182 (note that the flow discharge between the connecting ring 16 and the mounting post 182 is severe when the closed region 410c is replaced by an open region). The addition of the first projection 166 reduces the flow discharge between the attachment ring 16 and the mounting post 182 while ensuring smooth rotation of the attachment ring 16 relative to the mounting post 182.

In the present embodiment, the end surface of the connection ring 16 close to the limiting member 184 or the side surface of the limiting member 184 close to the connection ring 16 is provided with a plurality of second protrusions 168 arranged in a dispersed manner. Since the connection ring 16 can also move along the length direction of the mounting post 182, when the hollow spray arm 410 is rotated to spray water, a large gap may occur between the connection ring 16 and the limiting member 184, resulting in a serious discharge between the connection ring 16 and the limiting member 184. The added second protrusion 168 can reduce the flow discharge between the connection ring 16 and the position-limiting member 184 while ensuring a better mobility of the connection ring 16.

In the present embodiment, the inner diameter of the guide tube 416 is larger than the outer diameter of the connection tube 500, and the inner circumferential wall of the guide tube 416 or the outer circumferential wall of the connection tube 500 is provided with a plurality of third protrusions 500c arranged in a dispersed manner. The guide tube 416 has an inner diameter larger than an outer diameter of the connection tube 500, which facilitates the assembly of the guide tube 416 with the connection tube 500, and the larger the gap between the inner circumferential wall of the guide tube 416 and the outer circumferential wall of the connection tube 500, the more serious the discharge between the guide tube 416 and the connection tube 500. The third protrusion 500c is added to reduce the flow discharge between the guide tube 416 and the connection tube 500 while ensuring the smooth assembly of the guide tube 416 and the connection tube 500.

In the present embodiment, first protrusion 166, second protrusion 168, and third protrusion 500c are all tapered in the direction of extension. Wherein the first protrusion 166 tapers in a direction toward the free end of the first protrusion 166, further reduces the flow discharge between the attachment ring 16 and the mounting post 182 while ensuring smooth rotation of the attachment ring 16 relative to the mounting post 182. The second protrusion 168 tapers in a direction toward the free end of the second protrusion 168, which further reduces the flow discharge between the connection ring 16 and the stopper 184 while ensuring a better mobility of the connection ring 16. The third protrusion 500c is tapered in a direction toward the free end of the third protrusion 500c, which can further reduce the flow discharge between the guide tube 416 and the connection tube 500 while ensuring smooth assembly of the guide tube 416 and the connection tube 500.

In the present embodiment, as shown in fig. 1, the first shelf 12 has a through hole 12a through which the connection pipe 500 passes. The connection pipe 500 is inserted through the through hole 12a. Thus, the internal space of the baby bottle washing machine 10 is more conveniently arranged. It is understood that in other embodiments, the connection tube 500 may be located at one side of the first shelf 12, and in this case, the through hole 12a may be omitted.

In the present embodiment, the hollow spray arm 410 has water outlet holes 410a on both upper and lower sides thereof. Thus, water flow can be formed above and below the hollow spray arm 410 by the water outlet hole 410a, so that the rotation of the water flow formed by the water outlet hole 410a of the hollow spray arm 410 is facilitated.

In this embodiment, as shown in fig. 1, in order to fully utilize the water discharged from the water outlet hole 410a of the upper side of the hollow spray arm 410, the housing of the baby bottle washing machine 10 further includes a second shelf 18 for holding the baby bottle, the second shelf 18 being provided in the outer case and located above the upper spray assembly 400 and the first shelf 12. The hollow spray arm 410 is rotatably connected to the second shelf 18, so that the water outlet hole 410a on the upper side of the hollow spray arm 410 can spray water upwards to wash the bottle body 22 and/or the nipple 24 and/or the milk cap on the second shelf 18, the washed water falls down to the first shelf 12 under the action of gravity to wash the bottle body 22 and/or the nipple 24 and/or the milk cap on the first shelf 12 (both the water outlet hole 410a on the lower side of the hollow spray arm 410 and the water outlet hole 410a on the upper side of the hollow spray arm 410 can be used for washing the feeding bottle on the first shelf 12). In this way, the water from the outlet holes 410a on the upper side of the hollow spray arm 410 can be fully utilized, and different cleaning options can be provided for the user. In particular, in this embodiment, the second shelf 18 is primarily used for resting the nipple 24 and/or milk cap, as well as other novelties that require cleaning.

In this embodiment, the hollow spray arm 410 is indirectly mounted to the housing via the second shelf 18. It will be appreciated that in other embodiments, the hollow spray arm 410 may be provided directly on the housing, in which case the second shelf 18 may be omitted.

In this embodiment, the hollow spray arm 410 is movably coupled to the connection pipe 500. In this manner, when it is desired to place a bottle 22 and/or nipple 24 and/or a milk cap on first shelf 12, second shelf 18 and hollow spray arm 410 may be removed first to facilitate placement of a bottle 22 and/or nipple 24 and/or a milk cap on first shelf 12. It will be appreciated that in other embodiments, bottles 22 and/or nipples 24 and/or caps may be placed on first shelf 12 from the sides of first shelf 12 and second shelf 18 when the interior space of bottle washing machine 10 permits, and that prior removal of second shelf 18 and hollow spray arm 410 is not required.

The above is only the optional embodiment of the present invention, and not limiting the patent scope of the present invention, all under the inventive concept of the present invention, the equivalent structure transformation made by the contents of the specification and the attached drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
