Description

Technical Field

[0001] This invention relates to the field of multifunctional tea bar machine technology, specifically a teacup cleaning system. Background Technology

[0002] A tea bar machine is essentially an upgraded water dispenser, a household appliance that combines a water dispenser and a tea maker. As the functions of tea bar machines continue to improve, multi-functional tea bar machines that integrate cleaning and drying are increasingly in demand by users. Existing tea bar machine teacup cleaning systems simply rinse or soak teacups placed on a rack, which is insufficient for thoroughly cleaning the rims and the inner and outer walls near the rims. However, these areas are where our mouths directly contact the teacups when drinking tea; only by thoroughly cleaning these areas can the safety and hygiene of the teacups be effectively ensured. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art: to provide a teacup cleaning system for a tea bar machine, which can achieve water-saving, efficient, and all-round cleaning of the rims of multiple teacups and the inner and outer walls near the rims of the teacups.

[0004] Therefore, the purpose of this invention is to provide a teacup cleaning system, including a cleaning tank, a cleaning arm, and a circular shelf;

[0005] The cleaning arm is located at the bottom of the cleaning tank; the cleaning arm has a cavity inside, and the cleaning arm is provided with at least one nozzle with a spray hole communicating with the cavity; the nozzle is rotatably connected to the cleaning arm.

[0006] The circular shelf is equipped with a rotating shaft, which is rotatably engaged with the cleaning arm;

[0007] The bottom of the cleaning tank is equipped with a lifting and rotating drive mechanism; the lifting and rotating drive mechanism drives the circular shelf to lift and rotate via a rotating shaft.

[0008] The bottom of the cleaning tank is provided with a cup-shaped cover that communicates with the cavity of the cleaning arm; the outer wall of the cup-shaped cover is provided with a water supply pipe that communicates with its interior.

[0009] As an optimization, the lifting and rotating drive mechanism includes at least one lifting guide rod, a lifting plate, a rotating drive motor, and a lifting drive motor located at the bottom of the cleaning tank; the lifting plate is slidably engaged with the lifting guide rod; the lifting drive motor is driven by the lifting plate through a lead screw pair; and the rotating drive motor is fixed to the lifting plate.

[0010] As an optimization, the bottom of the cup-shaped cover is dynamically sealed to the rotating shaft; the output shaft of the rotary drive motor is hinged to the lower end of the rotating shaft; the upper end of the rotating shaft passes through the cleaning arm and is connected to the circular shelf.

[0011] Specifically, the nozzle includes a housing, on which at least one rim spray hole and at least one inner wall spray hole are provided; the rim spray hole is used to spray water jets to clean the rim of the teacup to be cleaned; the inner wall spray hole is used to spray water jets to clean the inner wall of the teacup to be cleaned; the housing is also provided with at least one bottom spray hole for spraying water jets to clean the bottom of the teacup to be cleaned.

[0012] As an optimization, the housing is also provided with a hollow shaft; the spray holes along the cup opening, the spray holes on the inner wall of the cup, and the spray holes at the bottom of the cup are all connected to the hollow shaft; an axial flow impeller is coaxially fixed inside the hollow shaft.

[0013] As an optimization, the hollow shaft is rotatably and sealedly connected to the cleaning arm; the housing is provided with an axial limiting fastener that mates with the flange on the cleaning arm, and the hollow shaft is movably sleeved on the cleaning arm and axially limited.

[0014] As an optimization, the axis of the spray hole along the cup opening intersects with or is not parallel to the axis of the spray hole on the inner wall of the cup.

[0015] As an optimization, the circular shelf is a grid frame with a barrier fence on the outer edge, and the bottom surface of the circular shelf has a radially inclined annular surface that is inclined toward the barrier fence.

[0016] The present invention has the following beneficial effects: The nozzle and the cleaning arm are rotatably connected. The nozzle has at least one spray hole along the rim of the cup and at least one spray hole along the inner wall of the cup, which can thoroughly clean the rim of the teacup and the inner and outer walls near the rim. If the circular shelf is driven to rotate and water of a certain pressure is introduced into the nozzle, water-saving, efficient and precise cleaning of the rims and inner and outer walls of multiple cups fixed in a ring on the circular shelf can be achieved. By driving the circular shelf to move up and down slightly, the water jets sprayed from the nozzles can not only focus on the rim and inner and outer walls of the teacup at the initial position, but also cover and rinse a wider area of ​​the inner and outer walls of the cup from both above and below.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0029] Now combined Figure 1-10 A teacup cleaning system is described, including a cleaning tank 1, a cleaning arm 2, and a circular shelf 3;

[0030] The cleaning arm 2 is located at the bottom of the cleaning tank 1; the cleaning arm 2 has a cavity 21 inside, and the cleaning arm 2 has two nozzles 22 with spray holes communicating with the cavity 21; the nozzles 22 are rotatably connected to the cleaning arm 2.

[0031] The circular shelf 3 is provided with a rotating shaft 31, which is rotatably engaged with the cleaning arm 2;

[0032] The bottom of the cleaning tank 1 is provided with a lifting and rotating drive mechanism 4; the lifting and rotating drive mechanism 4 drives the circular shelf 3 to lift and rotate via a rotating shaft 31.

[0033] The bottom of the cleaning tank 1 is provided with a cup-shaped cover 5 that communicates with the cavity 21 of the cleaning arm 2; the outer wall of the cup-shaped cover 5 is provided with a water supply pipe 51 that communicates with its interior.

[0034] The lifting and rotating drive mechanism 4 includes two lifting guide rods 41, a lifting plate 42, a rotating drive motor 43, and a lifting drive motor 44 located at the bottom of the cleaning tank 1; the lifting plate 42 is slidably engaged with the lifting guide rods 41; the lifting drive motor 44 is driven by the lifting plate 42 through a lead screw pair 45; and the rotating drive motor 43 is fixed on the lifting plate 42.

[0035] The bottom of the cup-shaped cover 5 is dynamically sealed to the rotating shaft 31; the output shaft of the rotary drive motor 43 is hinged to the lower end of the rotating shaft 31; the upper end of the rotating shaft 31 passes through the cleaning arm 2 and is connected to the circular shelf 3.

[0036] The nozzle 22 includes a housing 221, on which are provided two rim spray holes 222 and two inner wall spray holes 223; the rim spray holes 222 are used to spray water jets to clean the rim of the teacup to be cleaned; the inner wall spray holes 223 are used to spray water jets to clean the inner wall of the teacup to be cleaned; the housing 221 is also provided with two bottom spray holes 224 for spraying water jets to clean the bottom of the teacup to be cleaned.

[0037] The housing 221 is also provided with a hollow shaft 225; the spray hole 222 at the mouth of the cup, the spray hole 223 on the inner wall of the cup and the spray hole 224 at the bottom of the cup are all connected to the hollow shaft 225; an axial flow impeller 226 is coaxially fixed inside the hollow of the hollow shaft 225.

[0038] The hollow shaft 225 is rotatably and sealedly connected to the cleaning arm 2; the housing 221 is provided with an axial limiting fastener 227 that cooperates with the flange on the cleaning arm 2, and the hollow shaft 225 is movably sleeved on the cleaning arm 2 and axially limited.

[0039] The above structure allows the nozzle 22 to rotate relative to the cleaning arm 2, while water in the cleaning arm 2 is transmitted to all nozzles through the hollow shaft 225. Due to the presence of the axial impeller 226, the water passing through the hollow shaft 225 drives the nozzle 22 to rotate relative to the cleaning arm 2, thereby achieving water jet focusing on the rim and inner / outer wall areas of the teacup for rotary scanning cleaning. Since the rotary drive motor 43 can drive the circular shelf 3 to rotate, the lifting drive motor 44 can reciprocate by driving the lifting plate 42 via the lead screw pair 45 to achieve small-amplitude reciprocating lifting of the circular shelf 3. Figure 10 As shown, the axis of the spray hole 222 along the cup rim intersects with the axis of the spray hole 223 on the inner wall of the cup. This allows the water jet from the spray hole to not only focus on the rim and inner and outer wall areas of the cup at the initial position, but also to cover and rinse a wider area of ​​the inner and outer walls of the cup from both above and below.

[0040] The axes of the spray holes 222 along the cup rim and 223 on the inner wall of the cup intersect or are not parallel. This causes the water jets from the spray holes to be focused on the rim and inner and outer wall areas of the teacup.

[0041] The circular shelf 3 is a grid frame with a barrier fence on its outer edge, such as... Figure 3-4 As shown, the circular shelf 3 is welded from multiple radial and circumferential grid strips. The bottom surface of the circular shelf 3 has a radially inclined annular surface, which is inclined towards the barrier fence. The barrier fence and the annular surface are used to limit the inverted placement of teacups to be washed on the annular surface, so that the teacups to be washed can be evenly distributed along the annular surface. Specifically, the annular surface is a common surface formed by the upper surfaces of the inclined grid strips.

[0042] In use, the force exerted by the nozzle 22 on the teacup to be cleaned is controlled to be less than the weight of the teacup itself, so as to prevent the teacup from moving or tipping over. Preferably, the teacup to be cleaned is of a size and shape that matches the nozzle 22. Since this invention is used in a tea bar machine, a set of matching teacups is generally used. Preferably, any prior art device that can further limit or fix the teacup can also be provided on the cleaning tank 1, such as a lid for the cleaning tank 1 and a teacup pressure plate for fixing on the lid.

[0043] like Figure 4-5The example shown illustrates the application of this device. Cups to be cleaned are arranged in a uniform ring and placed upside down on a circular shelf 3 above the nozzle 22. The nozzles 222 along the cup rim are aligned with the rim of the cup, the nozzles 223 along the inner wall are aligned with the inner wall of the cup, and the nozzles 224 at the bottom of the cup are aligned with the bottom of the cup. Hot water at a certain pressure is supplied through the water pipe 51. The hot water passes through the cup-shaped cover 5, enters the cavity 21, and drives the axial flow impeller 226 through the hollow shaft 225 leading to the nozzle 22, causing the nozzle 22 to rotate. This allows the water jet from the nozzle 22 to focus on the rim and inner / outer wall areas of the cup for a rotating scanning cleaning. The circular shelf 3 is then rotated by the rotation drive motor 43 to achieve batch cleaning. The circular shelf 3 is raised and lowered slightly by the lifting drive motor 44, allowing the water jets from the nozzles to not only focus on the rim and inner / outer wall areas of the cup at the initial position but also to cover and rinse a wider area of ​​the cup's inner and outer walls from both above and below.
