Description

Technical Field

[0001] This utility model relates to down mixing equipment, and more particularly to an anti-tangling mixing mechanism for a down washing machine. Background Technology

[0002] In down processing, the washing process must avoid down tangling to ensure cleanliness and fiber integrity, but existing related mixing technologies have limitations in adaptability to different scenarios.

[0003] The utility model patent with patent number CN217795968U discloses a down mixing device, which uses an installation pipe with an air outlet in the mixing barrel and a base air supply component to send air into the barrel, assisting the mixing rod to disperse the dry down and solve the problem of adhesion when mixing (piling) down in the dry state. At the same time, a telescopic mixing rod is used to improve the mixing uniformity.

[0004] However, the core design goal of this device is to dry and mix down, which cannot meet the wet requirements of the washing scenario: First, its stirring rod and air supply structure are designed for dry environments. In water containing detergent, the airflow diffusion is obstructed, making it impossible to accurately disperse the down that is tangled due to the surface tension of water and the viscosity of detergent. Second, the stirring rod does not have a special anti-tangling design. In wet conditions, down is easily adsorbed and tangled on the rod. Moreover, the device does not solve the problem that the eddies generated during stirring during washing may cause down to gather and tangle, resulting in uneven washing and easy fiber damage. It is difficult to meet the requirements of low tangling and high cleanliness for down washing. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing an anti-tangling stirring mechanism for a down washing machine.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: An anti-tangling stirring mechanism for a down washing machine includes a machine housing, a stirring chamber inside the machine housing, and a stirring mechanism installed inside the stirring chamber. The stirring mechanism includes a stirring rod and a driver. The radial cross-section of the stirring rod is triangular star-shaped. An air passage is provided on the central axis of the stirring rod. Several air blowing holes are provided on the stirring arm of the stirring rod. All air blowing holes are connected to the air passage. A pipe connector is provided at one end of the air passage. The output end of the driver is connected to the pipe connector and drives the stirring rod to rotate.

[0007] Preferably, the pipe connector is provided with multiple air supply holes, and an air pump connector is fitted onto the pipe connector. The air pump connector is mounted on the pipe connector via a bearing, and the air pump connector is connected to the air passage through the air supply holes.

[0008] Preferably, the pipe joint is provided with an annular groove, the air outlet is located on the annular groove, and two bearings are fitted on the pipe joint, with the annular groove located between the two bearings.

[0009] Preferably, the end of the stirring arm is an arc-shaped surface, and the end of the stirring arm is provided with a number of notches corresponding to the number of air blowing holes, with the outlet of the air blowing holes located at the bottom of the notches.

[0010] Preferably, the air inlets are perpendicularly connected to the air passage, and the central axes of all air inlets are on the same plane.

[0011] Preferably, the machine casing is also equipped with a collection chamber located below the mixing chamber. The bottom of the mixing chamber is equipped with a discharge port that communicates with the collection chamber, and the top of the collection chamber is hinged with a lower cover plate to cover the discharge port.

[0013] Preferably, the top of the chassis is equipped with a funnel that communicates with the mixing chamber, and the side of the funnel is provided with an insertion hole, on which an upper cover plate is inserted and removed.

[0014] This utility model, by adopting the above technical solution, has significant technical effects: The triangular star shape of the stirring rod reduces the contact area between the down and the rod and guides the down to detach, reducing the probability of down entanglement caused by the surface tension of water and the viscosity of detergent in a wet state from the structural source; the air passage in the central shaft of the stirring rod is connected to the air blowing hole on the stirring arm, which can accurately deliver air to the core area where the down and the stirring rod are in contact, effectively breaking the entanglement.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to the embodiments.

[0021] Example 1 An anti-tangling stirring mechanism for a down washing machine includes a housing 10. Figure 1 One side panel of the middle casing 10 is not shown. The casing 10 is equipped with a mixing chamber 101, and a mixing mechanism is installed in the mixing chamber 101. The stirring mechanism includes a stirring rod 11 and a driver. In this embodiment, the driver is a motor. The radial cross-sectional shape of the stirring rod 11 is triangular star-shaped, that is, the stirring rod 11 is provided with three evenly distributed stirring arms 112. An air passage 111 is provided on the central axis of the stirring rod 11. A number of air blowing holes 113 are provided on the stirring arms 112 of the stirring rod 11. Each stirring arm 112 is provided with six air blowing holes 113. All air blowing holes 113 are connected to the air passage 111. A pipe connector 114 is provided at one end of the air passage 111. The output end of the driver is connected to the pipe connector 114 and drives the stirring rod 11 to rotate.

[0022] Working principle: The output end of the driver is directly connected to the pipe joint 114 at one end of the air passage 111 in the central shaft of the stirring rod 11. After the driver is started, it can drive the stirring rod 11 to rotate stably in the stirring chamber 101, thereby realizing the mechanical stirring of the down in the chamber. At the same time, the external air source is connected to the air passage 111 through the pipe joint 114. The airflow is conducted through the air passage 111 to the stirring arm 112 of the stirring rod 11, and is sprayed out from several air blowing holes 113 on the stirring arm 112 to complete the cleaning and anti-tangling treatment of the down.

[0023] The triangular star shape of the stirring rod 11 can significantly reduce the contact area between the down and the rod body, and the star-shaped edges can guide the down to detach from the rod body, reducing the probability of down entanglement caused by the surface tension of water and the viscosity of detergent during wet washing from the structural source; the air passage 111 of the stirring rod 11 and the air blowing hole 113 of the stirring arm 112 can directly spray air in the core area where the down and the stirring rod 11 are in contact, accurately breaking up the entangled down and improving the anti-entanglement effect.

[0024] The pipe connector 114 is provided with multiple air inlets 115. In this embodiment, there are three air inlets 115. An air pump connector 12 is fitted onto the pipe connector 114. The air pump connector 12 is connected to the air pump, which supplies gas to the air passage 111. The air pump connector 12 is mounted on the pipe connector 114 via a bearing 13 and is connected to the air passage 111 via the air inlets 115. The airflow delivered by the air pump connector 12 enters the air passage 111 of the stirring rod 11 more evenly and efficiently, reducing pressure loss during airflow transmission and ensuring the strength and stability of the airflow ejected from the air outlets 113 on the stirring arm 112, thereby improving the effect of dispersing and preventing tangling of wet down.

[0025] The pipe connector 114 is provided with an annular groove 116, and the air outlet 115 is provided on the annular groove 116. Two bearings 13 are fitted on the pipe connector 114, and the annular groove 116 is located between the two bearings 13. The annular groove 116 on the pipe connector 114, together with the air outlet 115 opened on the annular groove 116, can form an annular sealing fit between the air pump connector and the annular groove 116. No matter how the pipe connector 114 rotates with the stirring rod 11, the air outlet 115 can always be stably connected to the air pump connector.

[0026] The end of the stirring arm 112 is an arc-shaped surface 118, and the end of the stirring arm 112 is provided with notches 117 corresponding to the number of air holes 113. The outlet of the air holes 113 is located at the bottom of the notches 117. In wet cleaning scenarios, sharp structures can easily snag down fibers, aggravating down entanglement and potentially causing fiber wear. The arc-shaped surface 118 can eliminate the snagging points of sharp or right-angled structures on wet down, reducing the probability of down entanglement caused by snagging. At the same time, the gentle arc-shaped contact can reduce frictional damage to down fibers during stirring, ensuring the integrity of down fibers.

[0027] The air inlet 113 is vertically connected to the air passage 111, allowing the airflow to be ejected directly in a direction perpendicular to the radial direction of the stirring rod 11. The airflow impact direction is more in line with the entanglement direction of the down during the stirring process, which can directly disperse the radially gathered wet down. The central axis of all air inlets 113 is on the same plane.

[0028] The casing 10 also includes a collection chamber 102, located below the mixing chamber 101. The bottom of the mixing chamber 101 has a discharge port communicating with the collection chamber 102. A lower cover plate 103, hinged to the top of the collection chamber 102 to cover the discharge port, is sealed to the discharge port. The lower cover plate 103 is opened and closed by a cylinder push rod. The corresponding components are not shown in the accompanying drawings of this embodiment. By placing the collection chamber 102 below the mixing chamber 101 and directly connecting it to the discharge port at the bottom of the mixing chamber 101, the washed down feathers can fall into the collection chamber 102 under their own weight, eliminating the need for an external container. This achieves an integrated "washing-collection" process, preventing down feathers from scattering and significantly improving collection efficiency.

[0029] Windows 104 are installed on both sides of the casing 10. The windows 104 are equipped with baffles made of transparent material, which allow operators to clearly observe the cleaning progress, anti-tangling effect and material level of the down in the mixing chamber 101 in real time during the down cleaning and mixing process. The operation stage can be accurately judged without stopping the machine, avoiding incomplete cleaning or damage to the down due to blind operation.

[0030] The top of the casing 10 is equipped with a funnel 105 that communicates with the mixing chamber 101. Down is put into the mixing chamber 101 through the funnel 105. The side of the funnel 105 is provided with an insertion hole 106. An upper cover plate is inserted into the insertion hole 106. The upper cover plate is not shown in this embodiment.
