Description

Technical Field

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

[0002] With the widespread use of automated tableware cleaning equipment, the reliance on manual labor in tableware cleaning is decreasing. However, the maintenance and upkeep of the equipment still require the conscientiousness of the operators. The spray nozzles of the cleaning equipment need to be cleaned regularly to ensure cleaning effectiveness. However, customers often fail to perform regular cleaning and maintenance according to the cleaning process requirements, resulting in clogged or partially clogged spray nozzles and failure to achieve the designed cleaning effect. Therefore, an intelligent structure is needed to enable regular maintenance and upkeep of the equipment according to process requirements, ensuring both efficient use of the equipment and the cleanliness of the tableware. This effectively helps managers supervise operators' maintenance and upkeep work. Summary of the Invention

[0003] Purpose of this utility model: The purpose of this utility model is to address the shortcomings of existing technologies by developing a novel spray assembly for cleaning equipment. This assembly enables regular maintenance of the equipment according to process requirements, ensuring both efficient equipment use and thorough cleaning of tableware. It effectively assists managers in supervising operators' maintenance of the equipment.

[0004] Technical Solution: The present invention discloses a spray assembly for cleaning equipment, comprising a main water inlet pipe, the upper and lower ends of which are respectively connected to an upper spray assembly and a lower spray assembly, wherein both the upper and lower spray assemblies are fixed on a spray bracket, which is fixed on the frame of the cleaning equipment; the upper spray assembly includes an upper spray concentrator pipe and an upper spray branch pipe; the lower spray assembly includes a lower spray concentrator pipe and a lower spray branch pipe; water from the main water inlet pipe enters the upper and lower spray concentrator pipes and then flows into the spray branch pipes; it also includes an alert mechanism, which is disposed on one side of the main water inlet pipe and is connected to the spray assembly through a set of linkage components. The opening and closing of the alert mechanism is controlled by operating the linkage components; when the spray assembly is in operation, the alert mechanism starts operation; when the spray assembly has been used for a limited time, the alert mechanism issues an alarm to notify maintenance personnel to disassemble and clean the spray pipes.

[0005] Furthermore, as a preferred embodiment, the linkage assembly includes a linkage main rod located on one side of the main water inlet pipe. An upper limb rod is fixed to the upper part of the linkage main rod, and a lower limb rod is fixed to the lower end. An upper sleeve and a lower sleeve are provided on the linkage main rod between the upper and lower limb rods. The upper sleeve is fixedly connected to the linkage main rod. The lower sleeve is supported and fixed to the internal support plate, and the linkage main rod can rotate within the lower sleeve. The contact surfaces of both the upper and lower sleeves are inclined.

[0006] The reminder mechanism includes a trigger component, a limit switch, and a cumulative time relay. The trigger component includes a set of spring contact bars. After the top of the linkage main rod extends out of the top of the cleaning equipment box, an L-shaped pressure plate is fixed. When the spray assembly is installed in place, the upper limb rod abuts against the upper spray collection pipe, and the lower limb rod abuts against the lower spray collection pipe, causing the linkage main rod to rotate. This drives the L-shaped pressure plate at the top to press the spring contact bars, activating the limit switch. Once the system is powered on, the cumulative time relay starts to operate.

[0007] When the spray assembly is installed in place, the linkage main rod rotates, causing the upper sleeve to rotate. The tip of the upper sleeve moves to the tip of the lower sleeve, where its movement is obstructed and it stops, thus bringing the linkage assembly into a static equilibrium state.

[0008] After the cumulative time relay is activated, the cumulative operating time of the sprinkler assembly is recorded. Once the specified time is reached, an alarm is triggered to notify maintenance personnel to disassemble and clean the sprinkler assembly. After the sprinkler assembly is disassembled, the upper and lower limbs of the linkage main rod lose their resistance, breaking the static balance of the linkage assembly. Under the action of gravity, the tip of the upper sleeve slides down the slope of the lower sleeve, thereby driving the linkage main rod to rotate in the opposite direction. The limit switch is de-energized, and the cumulative time relay stops operating.

[0009] Furthermore, as a preferred embodiment, when the spray assembly is installed in place, the linkage main rod rotates counterclockwise from a top-down view; after the spray assembly is disassembled, the linkage main rod rotates clockwise from a top-down view.

[0010] Furthermore, as a preferred embodiment, the top of the linkage main rod is mounted on the top of the cleaning equipment housing via a set of bearings.

[0011] Furthermore, to avoid excessive rotation of the linkage main rod, an auxiliary limiting plate is provided on the top of the cleaning equipment housing, in front of the L-shaped pressure plate, to help limit the rotation range of the linkage main rod.

[0012] Beneficial effects: (1) The simple mechanism of this utility model can intelligently remind operators to clean equipment parts and perform regular maintenance of the equipment according to process requirements, which can ensure both the efficient use of the equipment and the cleanliness of the tableware. This effectively helps managers supervise operators' maintenance of the equipment. In this design, once the reminder mechanism issues a warning to clean, the warning can only be lifted and the timer reset by the worker disassembling the spray components, and then the next timer cycle can begin again. This avoids the problem of workers not disassembling and cleaning the spray components in time due to irresponsibility. (2) The use of this utility model solution can effectively improve the problem of spray pipe blockage or partial blockage caused by untimely cleaning of the spray pipe, which makes the cleaning effect not meet the design requirements and reduces the cleaning effect; (3) The application cleverly designs the upper sleeve and the lower sleeve, so that the upper sleeve and the linkage main rod operate as a whole, and the lower sleeve and the linkage main rod do not link; the tip and the inclined surface designed at the ends of the upper sleeve and the lower sleeve play a key role. Under normal operation of the spray pipe, the tip of the lower sleeve abuts against the tip of the upper sleeve to achieve static balance and remind the mechanism to start the operation when powered on; when the accumulated operation time reaches the set time, the spray pipe is removed for cleaning, the linkage main rod loses the resistance from the spray pipe, and the tip of the lower sleeve and the tip of the upper sleeve are no longer in a balanced state. The tip of the upper sleeve slides along the inclined surface of the lower sleeve under the action of gravity, which drives the linkage main rod to rotate, thereby causing the reminder mechanism to stop the operation when powered on. The key function of this application can be achieved through this exquisite and small modification, which greatly reduces the cost of equipment modification. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element; the terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Example 1: A spray assembly for a cleaning device includes a main water inlet pipe 1, with its upper and lower ends connected to an upper spray assembly 2 and a lower spray assembly 3, respectively. Both the upper spray assembly 2 and the lower spray assembly 3 are fixed to a spray bracket 4, which is fixed to the frame of the cleaning device. The upper spray assembly 2 includes an upper spray main pipe and upper spray branch pipes; the lower spray assembly 3 includes a lower spray main pipe 31 and a lower spray branch pipe 32. Water from the main water inlet pipe 1 enters the upper and lower spray main pipes and then flows into the spray branch pipes. It also includes a reminder mechanism 12 to provide reminders. The mechanism is located on one side of the main water inlet pipe 1. The reminder mechanism 12 is connected to the spray assembly through a set of linkage components. The linkage components include a linkage main rod 5, which is located on one side of the main water inlet pipe 1. The upper part of the linkage main rod 5 is fixed to the upper limb rod 6, and the lower part is fixed to the lower limb rod 7. An upper sleeve 8 and a lower sleeve 9 are provided on the linkage main rod 5 between the upper limb rod 6 and the lower limb rod 7. The upper sleeve 8 is fixedly connected to the linkage main rod 5. The lower sleeve 9 is fixed to the internal support plate 11 through the lower sleeve support 10. The linkage main rod 5 can rotate in the lower sleeve 9. The contact surfaces of the upper and lower sleeves are both inclined.

[0021] The reminder mechanism 12 includes a trigger component, a limit switch, and a cumulative time relay. The trigger component includes a set of spring contact bars 121. The top of the linkage main rod 5 is mounted on the top of the cleaning equipment housing 13 through a set of bearings. After the top of the linkage main rod 5 extends out of the top of the cleaning equipment housing 13, the L-shaped pressure plate 14 is fixed. When the spray assembly is installed in place, because the upper limb rod 6 abuts against the upper spray collection pipe and the lower limb rod 7 abuts against the lower spray collection pipe 31, the linkage main rod 5 rotates counterclockwise from the top view, which drives the L-shaped pressure plate 14 at the top to press the spring contact bars 121 and activate the limit switch. Once the system is powered on, the cumulative time relay starts to work.

[0022] With the spray assembly in place, the linkage main rod 5 rotates, causing the upper sleeve 8 to rotate. The tip of the upper sleeve 8 stops moving when it reaches the tip of the lower sleeve 9, thus bringing the linkage assembly into a static equilibrium state. An auxiliary limiting plate 15 is provided on the top of the cleaning equipment housing in front of the L-shaped pressure plate 14 to help limit the rotation amplitude of the linkage main rod 5.

[0023] After the cumulative time relay operates, the cumulative operating time of the upper spray assembly 2 and the lower spray assembly 3 is accumulated. Once the limited time is reached, a reminder alarm is issued to notify maintenance personnel to disassemble and clean the upper spray assembly 2 and the lower spray assembly 3. After the upper spray assembly 2 and the lower spray assembly 3 are disassembled, the upper limb rod 6 and the lower limb rod 7 of the linkage main rod 5 lose their resistance, breaking the static balance of the linkage assembly. Under the action of gravity, the tip of the upper sleeve 8 slides down the inclined surface of the lower sleeve 9, thereby driving the linkage main rod 5 to rotate clockwise from the top view. The limit switch is de-energized, the cumulative time relay stops operating, and the cumulative time relay is reset to zero, entering the next timing cycle.

[0024] The operating principle of this device is as follows: When the upper spray assembly 2 and lower spray assembly 3 are installed in place, the upper limb rod 6 abuts against the upper spray collection pipe, and the lower limb rod 7 abuts against the lower spray collection pipe. From a top-down perspective, this causes the linkage main rod 5 to rotate counterclockwise, driving the top L-shaped pressure plate 14 to press the spring contact strip 121, activating the limit switch. Once the system is powered on, the cumulative time relay begins operation. The cumulative time relay in the electrical control section calculates the operating time under the energized state of the limit switch. When the accumulated operating time reaches the set value for cleaning the spray pipes... At the designated time, the equipment stops spraying until the upper spray assembly 2 and lower spray assembly 3 are disconnected from the main water inlet pipe. The upper limb rod 6 and lower limb rod 7 lose their resistance, causing the linkage main rod 5 to lose the resistance of the spray collection pipe. This breaks the static balance of the linkage assembly. Under gravity, the tip of the upper sleeve 8 slides down the slope of the lower sleeve 9, causing the linkage main rod 5 to rotate clockwise from a top-down perspective. This causes the tip of the upper sleeve 8 to rotate to approximately the middle position of the lower sleeve 9's slope. The L-shaped pressure plate 14 then leaves the spring contact of the limit switch, and the limit switch disconnects. The cumulative time relay also disconnects and resets to zero, entering the next timing cycle. After the spray pipes are cleaned, they are reinstalled. The linkage main rod 5 rotates counterclockwise, and the tips of the upper sleeve 8 and lower sleeve 9 are aligned again, reaching static balance. The L-shaped pressure plate 14 again triggers the limit switch contact, activating the limit switch, and the cumulative time contactor begins calculation.

[0025] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
