A spray device for a baby bottle cleaning machine and the baby bottle cleaning machine
[0001] This application claims priority to Chinese patent application No. 202422811141.3, filed on November 18, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the technical field of baby bottle cleaning machines, specifically to a spray device for a baby bottle cleaning machine and the baby bottle cleaning machine itself. Background Technology
[0003] Currently, in some childcare facilities, baby bottles need to be cleaned and sterilized before and after use to ensure the health of infants. Based on this, existing technologies have developed bottle cleaning machines for cleaning and sterilizing bottles, providing great convenience. Existing bottle cleaning machines typically include a water supply system, a hollow column, a bottle holder, a nipple holder, and a spray arm mounted on the column. In use, the bottle is usually placed upside down on the bottle holder, and the nozzles on the holder clean the inside of the bottle, while the spray nozzles on the spray arm clean the outside. In existing technology, the spray arm is directly fitted onto the column, and then the nipple holder presses the spray arm down from above. However, this connection is unstable. Because the spray arm generates a reverse thrust when spraying water downwards, it is prone to sliding upwards and losing contact between the water channels inside the spray arm and the water channels inside the column, thus affecting the spraying effect. Therefore, improvements are needed. Technical issues
[0004] This application provides a spray device for a baby bottle cleaning machine and a baby bottle cleaning machine, aiming to solve the problem that the connection between the spray arm and the column in the prior art baby bottle cleaning machine is unstable, which easily leads to instability of the spray arm when spraying water. Technical solutions
[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows:
[0006] In a first aspect, this application provides a spray device for a baby bottle washing machine, comprising:

[0036] Example
[0037] As shown in Figures 1 to 3, this embodiment provides a spray device for a baby bottle washing machine, including:
[0038] The base frame is equipped with a water supply system;
[0039] A water-guiding column 1, mounted on a base frame, has a water-guiding channel 13 extending upwards and communicating with the water supply assembly; and...
[0040] The upper spray arm 2 is sleeved on the upper part of the water guide column 1 and has a number of spray holes on the upper spray arm 2 that are connected to the water guide channel 13.
[0041] A locking assembly is provided between the upper spray arm 2 and the water guide column 1 to engage the upper spray arm 2 onto the water guide column 1. The locking assembly includes a first locking part located on the upper spray arm 2 and having elasticity, and a second locking part located on the outer wall of the water guide column 1. The first locking part engages with the second locking part under the action of elasticity. By engaging with the second locking part, the upper spray arm 2 and the water guide column 1 form a stable connection.
[0042] In some specific embodiments, as shown in Figures 1 and 2, the spray holes of the upper spray arm 2 include upper spray holes that can spray water upwards, lower spray holes that can spray water downwards, and oblique spray holes 24 that drive the upper spray arm 2 to rotate around the water guide column 1 by spraying water. There are two oblique spray holes 24, which are located on opposite sides of the upper spray arm 2. When the two oblique spray holes 24 spray water, the reaction force drives the upper spray arm 2 to rotate around the water guide column 1, so as to achieve rotational spraying to clean more bottles 5 or nipples. Specifically, the upper spray arm 2 is provided with an upper spray arm 2 channel that communicates with the water guide channel 13, and the spray holes of the upper spray arm 2 are all connected to the upper spray arm 2 channel.
[0043] In some specific embodiments, as shown in Figures 1 to 3, the first engaging part is an elastic hook 22, and the second engaging part is a locking block 12. The elastic hook 22 hooks onto the locking block 12 to fix the upper spray arm 2 to the water guide column 1. Specifically, the locking block 12 can be a protrusion provided on the surface of the water guide column 1, and the hook end of the elastic hook 22 hooks onto the locking block 12.
[0044] In some specific embodiments, the first engaging part is an elastic hook 22, and the second engaging part is a groove. The elastic hook 22 fixes the upper spray arm 2 to the water guide column 1 by hooking into the groove. The groove can be formed by the outer wall of the water guide column 1 being recessed inward, or by the groove being formed between two upper and lower protrusions on the outer wall of the water guide column 1.
[0045] In some specific embodiments, as shown in Figures 1 to 3, there are two elastic hooks 22, which are located on opposite sides of the lower end of the upper spray arm 2 respectively; the upper end of the elastic hook 22 is preferably integrally formed with the upper spray arm 2, and the lower end of the elastic hook 22 is provided with a hook end that hooks against the locking block 12.
[0046] The second engaging part is preferably a locking block 12, and the locking block 12 is an annular locking block arranged around the water guiding column 1. The elastic hook 22 hooks onto the lower side of the locking block 12 and can rotate around the annular locking block 12. Specifically, after the two elastic hooks 22 hook onto the locking block 12 from opposite sides, the upper spray arm 2 can be balanced by forces on opposite sides, preventing tilting. When the upper spray arm 2 rotates to spray water, the elastic hook 22 can rotate around the annular locking block 12, and always hooks onto the lower side of the locking block 12 during the rotation.
[0047] As shown in Figures 1 to 3, to facilitate the installation of the upper spray arm 2, the annular locking block 12 has an upper guide surface on its upper surface and a lower guide surface on its lower surface, with elastic hooks 22 hooking onto the lower guide surface. Specifically, when installing the upper spray arm 2, the two elastic hooks 22 slide downwards along the upper guide surface until they hook onto the lower guide surface. To facilitate the rotation of the elastic hooks 22 around the locking block 12, the elastic hooks 22 are preferably fitted against the lower guide surface, thus providing greater stability during rotation.
[0048] In some specific embodiments, as shown in Figures 1 and 2, in order to limit the position of the upper spray arm 2 on the water guide column 1 and prevent it from sliding up and down, an annular step 11 is provided around the upper part of the outer wall of the water guide column 1 and above the locking block 12. The upper spray arm 2 has a through hole in the middle that fits onto the water guide column 1, and the upper side of the inner wall of the through hole has an annular abutment part 21 that abuts against the upper surface of the annular step 11. When the elastic hook 22 is hooked on the locking block 12, the annular abutment part 21 abuts against the annular step 11. Specifically, when the elastic hook 22 is hooked on the lower guide surface of the locking block 12, the annular abutment part 21 abuts against the upper surface of the annular step 11, thereby limiting the up and down position of the upper spray arm 2 and preventing the upper spray arm 2 from sliding up or down.
[0049] In some specific embodiments, as shown in Figure 1, the water-guiding column 1, in addition to the upper spray arm 2, also includes a lower spray arm 3 sleeved on the lower part of the water-guiding column 1. The lower spray arm 3 has spray holes that communicate with the water-guiding channel 13. The lower spray arm 3 also has an upward spray hole 23 for spraying water. A bottle holder 4 is also sleeved on the water-guiding column 1, located between the upper spray arm 2 and the lower spray arm 3. The bottle holder 4 has several bottle placement positions, each with a nozzle for cleaning the inside of the bottle 5, and all nozzles are connected to the water-guiding column 1.
[0050] Example
[0051] As shown in Figures 1 to 3, this application provides a baby bottle cleaning machine, including a spray device on a baby bottle cleaning machine according to any of the above embodiments, and also includes a machine body 6, wherein the spray device is disposed inside the machine body 6.
[0052] Working principle explanation:
[0053] After the upper spray arm 2 is installed on the water guide column 1, the two elastic hooks 22 hook onto the lower guide surface of the locking block 12 from opposite sides, thereby preventing the upper spray arm 2 from sliding upward along the water guide column 1. At the same time, the lower surface of the annular abutment part 21 abuts against the upper surface of the annular step 11, thereby preventing the upper spray arm 2 from sliding downward along the water guide column 1. The above connection structure can limit the upper and lower positions of the upper spray arm 2, making its connection with the water guide column 1 more stable.
[0054] This application is not limited to the above-mentioned optional implementation methods. Under the premise of not conflicting with each other, the solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this application. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this application shall fall within the protection scope of this application.
