Description

Technical Field

[0001] This utility model relates to the field of washing equipment technology, specifically to a positionable cleaning spray assembly. Background Technology

[0002] The spray assembly of existing baby bottle washing machines mainly adopts a combination of a fixed spray column structure that extends into or faces the bottle opening and a rotating spray arm structure. Because the water channel of this spray assembly has many branches and a large number of nozzles, the dynamic pressure of the water channel is low under the condition of a fixed water pump power, resulting in insufficient spray impact force. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a positionable cleaning spray assembly, which can realize continuous rotating spraying and positional spraying, reduce water path branches and nozzle dynamic pressure dispersion, and help improve the cleaning effect.

[0004] The technical solution adopted in this utility model is: a positionable cleaning spray assembly, comprising:

[0005] A first rotating spray arm, wherein the first rotating spray arm is provided with a first nozzle that sprays upwards;

[0006] A drive motor, the power output end of which is connected to the first rotating spray arm via a transmission connection;

[0007] A first shelf is disposed above a first rotating spray arm; the first shelf is provided with at least one first storage slot;

[0008] The drive modes of the drive motor include at least:

[0009] First mode: Continuous operation drives the first rotating spray arm to rotate;

[0010] Second mode: Stop rotating according to the positioning signal, so that the spray direction of the first nozzle is positioned to the corresponding first storage slot.

[0011] To further optimize this technical solution, a second rotating spray arm is coaxially, fixedly, and fluidly connected above the first rotating spray arm, and the second rotating spray arm is provided with a second spray nozzle that is angled upward.

[0012] A second shelf is provided above the first shelf; the second shelf is provided with at least one second storage slot;

[0013] When the drive motor is in the second mode, the third nozzle spray direction is positioned to the corresponding second storage slot.

[0014] To further optimize this technical solution, a second rotating spray arm of a positionable cleaning spray assembly is provided with a third nozzle for lateral spraying.

[0015] To further optimize this technical solution, the drive motor is located at the top of the second rotating spray arm and is in transmission cooperation with the second rotating spray arm; the second rotating spray arm drives the first rotating spray arm to rotate synchronously through its fixed connection with the first rotating spray arm.

[0016] To further optimize this technical solution, the positioning signal is generated by a position sensor that responds to changes in the relative position of the first rotating spray arm and the first shelf.

[0017] To further optimize this technical solution, the drive motor is a stepper motor, and the positionable cleaning spray assembly also includes a pulse distributor circuit, which presets a pulse sequence corresponding to the position of each first placement slot.

[0018] In the technical solution described in this utility model, the first rotating spray arm, driven by a drive motor, can continuously rotate to rinse the baby bottles on the first shelf. The direct spray range includes the inner wall of the baby bottle, and the dripping water from the top can cover the outer wall of the baby bottle, resulting in a large coverage area. Baby bottles can be positioned in the first shelf compartment. When the drive motor is in the second driving mode, the first nozzle can be positioned to spray onto the inner wall of the corresponding baby bottle in the first shelf compartment, achieving the fixed-point rinsing effect of a traditional fixed spray column. This reduces water path branches and nozzle dynamic pressure dispersion, thus improving the cleaning effect.

[0019] The second shelf has a second storage slot where bottle caps and nipple accessories can be placed. The second nozzle can be continuously rotated for rinsing or positioned for rinsing.

[0020] Other technical effects of this utility model will be gradually explained in the unfolding of the embodiments. Attached Figure Description

[0026] A positionable cleaning spray assembly, comprising:

[0027] A first rotating spray arm 4 is provided with an upward spray nozzle 5;

[0028] The drive motor 6 is connected to the first rotating spray arm 4 via a transmission connection.

[0029] A first shelf 7 is disposed above the first rotating spray arm 4; the first shelf 7 is provided with at least one first storage slot 8;

[0030] The driving modes of the drive motor 6 include at least:

[0031] First mode: Continuous operation drives the first rotating spray arm 4 to rotate;

[0032] Second mode: Stop rotating according to the positioning signal, so that the spray direction of the first nozzle 5 is positioned to the corresponding first storage slot 8.

[0033] The number of first storage slots 8 can be one or more; multiple first storage slots 8 can hold multiple baby bottles 14, or baby bottle caps 15 and nipples; the baby bottles 14, bottle caps 15 or nipples are placed on the first storage slots 8 with their openings facing downwards. The number of first nozzles 5 can be single, or they can be all or some of them corresponding to the positions of the first storage slots 8;

[0034] like Figure 1 As shown, when the drive motor 6 is in the first mode, when the jet from the first nozzle 5 reaches the top cover 3 of the bottle cleaner 1, it will splash downwards, and the splashed water can clean the outer walls of the bottle 14 and the bottle cap 15; when the drive motor 6 is in the second mode, the jet from the first nozzle 5 is positioned and sprayed towards the corresponding first storage compartment 8; according to the relative number and position distribution of the first storage compartment 8 and the first nozzle 5, the number, position and duration of the stop points of the drive motor 6 in the second mode are set. Figure 1 The number of first storage slots 8 is set to four, and the number of first nozzles 5 is set to two sets symmetrically, with two nozzles in each set. The drive motor 6 has two stop points, each stop point being distributed for the two first storage slots 8 symmetrically set in each set. The control circuit of the baby bottle washing machine 1 can set the cleaning time of each set of first storage slots 8 to 2-7 minutes.

[0035] The drive motor 6 can be installed below the first rotating spray arm 4, and the drive motor 6 is installed in a waterproof structure at the bottom of the body 2 of the baby bottle washing machine 1. Figure 1As shown, the drive motor 6 is preferentially installed on the top cover 3 of the bottle washing machine 1, and the first shelf 7 is placed on the inner wall of the body 2 of the bottle washing machine 1; the phase angle between the first shelf 8 and the drive motor 6 can be determined by the installation and positioning of the body 2, the top cover 3, and the first shelf 7 of the bottle washing machine 1; the specific implementation methods include, but are not limited to, slot positioning, guide rail positioning, or shape matching positioning.

[0036] The rotational connection between the first rotating spray arm 4 and the bottle washing machine 1, as well as the water pump and water circuit connection, are all existing technologies and are omitted.

[0037] Further optimization of this embodiment:

[0038] like Figure 2 As shown, a second rotating spray arm 9 is coaxially, fixedly, and fluidly connected above the first rotating spray arm 4, and the second rotating spray arm 9 is provided with a second nozzle 10 that is angled upward.

[0039] A second shelf 11 is provided above the first shelf 7; the second shelf 11 is provided with at least one second storage slot 12;

[0040] When the drive motor 6 is in the second mode, the spray direction of the third nozzle 13 is positioned to the corresponding second storage slot 12.

[0041] Since some users will wash multiple baby bottles 14 at the same time, the second shelf 11 can be used to place baby bottle 14, bottle cap 15, nipple, gravity ball, straw and other baby bottle parts after the first shelf 7 is full of baby bottles 14.

[0042] The first rotating spray arm 4 and the second rotating spray arm 9 rotate synchronously and are connected by water channels; the number of second storage troughs 12 can be one or more; the number of second nozzles 10 can be single, or they can be all or some of them corresponding to the positions of the second storage troughs 12. Figure 2 The second nozzle 10 and the second storage slot 12 are both provided with four.

[0043] like Figure 2 , Figure 3 As shown, in a further optimized embodiment, the second rotating spray arm 9 is provided with a third nozzle 13 for lateral spraying.

[0044] The function of the third nozzle 13 is to rinse the body of the baby bottle 14 and the inner wall of the baby bottle washing machine 1 from the side. The spray angle of the third nozzle 13 can be between 0° and 60° with the horizontal plane, and the third nozzle 13 can also be set as a fan-shaped nozzle.

[0045] Figure 1As shown, in a further optimized embodiment, the drive motor 6 is located on the top of the second rotating spray arm 9 and is in transmission cooperation with the second rotating spray arm 9; the second rotating spray arm 9 drives the first rotating spray arm 4 to rotate synchronously through its fixed connection with the first rotating spray arm 4.

[0046] like Figure 4 As shown, the power output end of the drive motor 6 slides into the top of the second rotating spray arm 9, with radial transmission and axial detachable connection. The second rotating spray arm 9 is a tubular structure with a sealed top. Thus, no fluid flows between the drive motor 6 and the second rotating spray arm 9; only transmission is involved. Placing the drive motor 6 at the top facilitates waterproofing, requiring only a rotating seal between the drive motor 6's power output shaft and the top cover 3. The connection between the drive motor 6 and the control circuit of the bottle washing machine 1 is achieved through detachable electrode contacts between the top cover 3 and the machine body 2. Alternatively, the top cover 3 can be fixedly connected to the machine body 2, and the first shelf 7 and the second shelf 11 can be horizontally opened and closed with the machine body 2 via a drawer-type structure.

[0047] As a preferred embodiment of the above, the positioning signal is generated by a position sensor that responds to changes in the relative position of the first rotating spray arm 4 and the first shelf 7.

[0048] In the second mode, the drive motor 6 forms a closed-loop feedback with the position sensor to determine that the jet direction of the first nozzle 5 of the first rotating spray arm 4 corresponds to the first storage tray 8. The position sensor can be a Hall sensor located between the first rotating spray arm 4 and the bottom of the inner cavity of the bottle cleaner 1, or it can be a reed switch sensor assembly.

[0049] As a preferred embodiment of the above, the drive motor 6 is a stepper motor, and the positionable cleaning spray assembly further includes a pulse distributor circuit, which presets a pulse sequence corresponding to the position of each first placement slot 8.

[0050] In the second mode, the drive motor 6 is a stepper motor, and positioning is achieved by using an open-loop pulse sequence preset by the pulse distributor circuit.

[0051] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0052] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
