Technical Field
[0001] This utility model relates to the field of tea bar machines, and in particular to a dustproof heating base for a tea bar machine. Background Technology
[0002] Existing tea bar machine heating bases are typically exposed to the elements, lacking effective dust protection. This allows dust to easily accumulate in the heating area over time, affecting heating efficiency, potentially causing internal dust buildup, reducing lifespan, and even compromising drinking water hygiene. Some existing solutions use fixed dust covers, but these require manual opening and closing, which is inconvenient and cannot be coordinated with the placement and removal of the kettle, resulting in a poor user experience. Utility Model Content
[0003] The purpose of this invention is to provide a dustproof heating base for a tea bar machine, solving the problem that the heating base of a traditional tea bar machine is exposed to the outside and easily accumulates dust.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof heating base for a tea bar machine, comprising a body, the upper part of which is provided with a water receiving platform, the water receiving platform being divided into a water receiving area and a heating area, a heating base being provided in the heating area, a settling trough being opened in the heating area, the heating base being located at the center of the settling trough, and a dustproof device being provided around the heating base. The dustproof device includes a linkage drive mechanism; An iris opening and closing mechanism is located directly above the heating base. The iris opening and closing mechanism includes a fixed outer ring, a rotatable inner ring, and a valve plate whose opening and closing are controlled by the rotation of the rotatable inner ring, and a telescopic support column supported on the fixed outer ring. The linkage drive mechanism includes: A guide tube is fixedly disposed below the heating base, and a spiral path is provided on the surface of the guide tube; The transmission rod has its upper end fixedly connected to the rotating inner ring, and its lower end has a transmission part that engages with the spiral path.
[0005] Furthermore, a sealing cover is provided on the fixed outer ring, and an opening matching the diameter of the heating base is provided in the center of the sealing cover. A sealing ring is provided below the fixed outer ring, and the sealing ring extends downward and slides against the inner wall of the settling tank.
[0006] Furthermore, the inner wall of the settling tank is provided with a vertical lifting guide groove, and a guide slider is fixed on the circumferential surface of the sealing ring. The guide slider is fitted into the lifting guide groove and can slide along it.
[0007] Furthermore, the fixed outer ring has a ring matrix with multiple guide pins, and the rotating inner ring has crescent-shaped holes matching the number of guide pins. The guide pins pass through the corresponding crescent-shaped holes to restrict the radial degree of freedom of the rotating inner ring. A support ring is fixedly provided on the inner side of the rotating inner ring. One end of the valve plate is hinged to the support ring, and the other end is hinged to the inner area of the crescent-shaped hole of the rotating inner ring through a crescent-shaped connecting rod.
[0008] Furthermore, a support ring is fixedly provided on the inner side of the rotating inner ring, one end of the valve plate is hinged to the support ring, and the other end is hinged to the inner area of the crescent hole of the rotating inner ring through a crescent connecting rod.
[0009] Furthermore, the support ring is provided with a through hole that matches the diameter of the heating base. When the valve plate is open, it surrounds a circular hole with the same diameter as the through hole. When closed, it surrounds a disc.
[0010] Furthermore, the telescopic support includes an inner column, an outer column, and a compression spring. The inner column is vertically connected to the bottom of the settling tank. The outer column is sleeved above the inner column and can slide. The top of the outer column is connected to the bottom surface of the fixed outer ring. The compression spring is located inside the inner column and is connected to the outer column.
[0011] Furthermore, the machine body also includes an operation panel, which is located at the upper end of the machine body.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Designed to solve the problem of dust accumulation on the exposed heating base of traditional tea bar machines, this invention achieves automatic opening of the heating base when a kettle is placed in the heating area and automatic closing and sealing after the kettle is removed by incorporating a settling tank and dustproof device in the heating zone. Specifically, it utilizes an iris opening and closing mechanism combined with a linkage drive mechanism. The technical solution involves creating a settling tank in the heating zone, with the heating base positioned at the center. A dustproof device consisting of an iris opening and closing mechanism and a linkage drive mechanism surrounds the iris opening and closing mechanism. The iris opening and closing mechanism is supported by a telescopic support column and presses down according to the weight of the kettle. The transmission rod in the linkage drive mechanism moves through a spiral guide tube, causing the inner ring of the iris opening and closing mechanism to rotate and control the valve plate to open and close. The advantages of this technical solution are that it automatically opens the heating base when the kettle is placed in the heating area, ensuring heating efficiency, and automatically closes and seals after the kettle is removed, effectively preventing dust from entering the heating base, keeping it clean, extending the equipment's lifespan, and improving user convenience and hygiene.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0017] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.
[0018] like Figures 1 to 9As shown, this utility model provides a dustproof heating base for a tea bar machine, including a body 1. The body 1 has a double-layer cabinet structure. The upper surface of the upper cabinet serves as a water receiving platform 11, which is divided into a water receiving area 111 and a heating area 112. A water outlet pipe is provided above the body 1. The water outlet pipe can rotate and alternate between the water receiving area 111 and the heating area 112. A circular settling trough 113 is opened in the area of the heating area 112. A heating base 2 is provided at the center of the settling trough 113. An electric heating tube is provided in the heating base 2 for heating the kettle. A dustproof device 3 is provided around the heating base 2. The dustproof device 3 includes an iris opening and closing mechanism 31 and a linkage drive mechanism 32. The iris opening and closing mechanism 31 is located directly above the heating base 2. The iris opening and closing mechanism 31 includes a fixed outer ring 311, a rotatable inner ring 312, and a valve plate 313 whose opening and closing are controlled by the rotation of the inner ring 312. A telescopic support 314 is supported on the fixed outer ring 311. When the kettle is not placed on the iris opening and closing mechanism 31, it is directly above the heating base 2. When the kettle is placed on the iris opening and closing mechanism 31, it presses the mechanism into the settling groove 113. At this time, the valve plate 313 is open, and the heating base 2 passes through. After the valve plate 313 opens the channel and exposes it to the water receiving platform 11, the kettle can be inserted into the heating base 2, which can then heat the kettle. The telescopic support column 314 adopts an elastic reset type lifting column, which is an existing mature structure and will not be described in detail. When the kettle leaves the heating base 2, the telescopic support column 314 will reset the iris opening and closing mechanism 31, allowing the iris opening and closing mechanism 31 to return to the top of the heating base 2, and the valve plate 313 will be in the closed state, preventing the heating base 2 from being directly exposed to the outside world and effectively preventing dust from entering the heating base 2.
[0019] The principle of rotation of the inner rotating ring 312 of the iris opening and closing mechanism 31 during descent: When the kettle is placed above the iris opening and closing assembly, the iris opening and closing assembly moves downward under gravity due to the support of the telescopic support column 314. During this process, the upper end of the transmission rod 323 is fixed to the inner rotating ring 312, while the lower end of the transmission rod 323 is provided with a transmission part 324. This transmission part 324 engages with the spiral path 322 on the surface of the guide tube 321. As the iris opening and closing assembly moves downward, the lower end of the transmission rod 323 slides along the spiral path 322 of the guide tube 321. Since the spiral path 322 of the guide tube 321 is inclined and spiral-shaped, the lower end of the transmission rod 323 slides along the spiral path 322 of the guide tube 321 as it moves downward. The transmission part 324 will generate lateral displacement along the spiral path 322, thereby driving the transmission rod 323 to rotate as a whole. Since the upper end of the transmission rod 323 is fixed to the inner rotating ring 312, the rotation of the transmission rod 323 will directly drive the inner rotating ring 312 to rotate synchronously, thereby driving the valve plate 313 to open. Conversely, when the iris opening and closing assembly rises and resets, the lower end of the transmission rod 323 slides in the opposite direction along the spiral path 322, which will also drive the inner rotating ring 312 to rotate in the opposite direction, causing the valve plate 313 to close, achieving dustproof sealing. This utility model utilizes the linkage between the spiral guide and the transmission rod 323 to enable the iris opening and closing assembly to achieve rotational opening and closing while moving vertically, ensuring the automatic sealing and dustproof effect of the heating base 2.
[0020] A sealing cover 4 is provided on the fixed outer ring 311. The sealing cover 4 has an opening in the center that matches the diameter of the heating base 2. A sealing ring 5 is provided below the fixed outer ring 311. The sealing ring 5 extends downward and slides against the inner wall of the settling groove 113. The sealing cover 4 covers the top of the outer ring and has an opening in the middle that is the same diameter as the heating base 2, so that the base can be added through the opening when it descends. The sealing cover 4 is in direct contact with the kettle. The sealing cover 4 will also descend with the iris opening and closing mechanism 31. When the iris opening and closing mechanism 31 descends to the lowest point... At this time, the upper surface of the sealing cover 4 is flush with the water receiving platform, which serves to support the kettle and prevent the heating base 2 from directly supporting the kettle and causing the heating tube inside the heating base 2 to bend and be damaged. At the same time, a sealing ring 5 is provided below the fixed outer ring 311. The sealing ring 5 wraps around the upper part of the telescopic support column 314. When the iris opening and closing mechanism 31 is above the settling tank 113, the sealing ring 5 is used to seal the circumference of the iris opening and closing mechanism 31. The axial height of the sealing ring 5 is equal to half the height of the settling tank 113.
[0021] The inner wall of the settling trough 113 is provided with a vertical lifting guide groove 114, and a guide slider 51 is fixed on the circumference of the sealing ring 5. The guide slider 51 is embedded in the lifting guide groove 114 and can slide along it, making the lifting and sliding more stable and avoiding deviation and jamming.
[0022] The fixed outer ring 311 has a plurality of guide pins 317 arranged in an annular matrix. The rotating inner ring 312 has crescent holes 318 matching the number of guide pins 317. The guide pins 317 pass through the corresponding crescent holes 318 to restrict the radial degree of freedom of the rotating inner ring 312. A support ring 315 is fixedly provided on the inner side of the rotating inner ring 312. One end of the valve plate 313 is hinged to the support ring 315, and the other end is hinged to the inner area of the crescent holes 318 of the rotating inner ring 312 through a crescent connecting rod 316. A support ring 315 is fixedly provided on the inner side of the rotating inner ring 312. One end of the valve plate 313 is hinged to the support ring 315, and the other end is hinged to the inner area of the crescent hole 318 of the rotating inner ring 312 through the crescent connecting rod 316. The iris opening and closing mechanism 31 realizes the opening and closing control of the iris (i.e., the valve plate 313) through the relative rotation of the fixed outer ring 311 and the rotating inner ring 312. The core purpose of its structural design is to convert the rotational motion into the linear opening and closing action of the valve plate 313, while ensuring the precise guidance and stable transmission of the motion. The specific principle is as follows: multiple guide pins 317 are evenly distributed on the fixed outer ring 311, and the rotating inner ring 312 is provided with the same number of crescent holes 318. After the guide pins 317 pass through the crescent holes 318, the rotating inner ring 312 is allowed to rotate around the axial direction, and its radial displacement is restricted by the contour of the crescent holes 318, thereby ensuring that the rotating inner ring 312 can only rotate along a preset trajectory. The support ring 315 fixed to the inner side of the rotating inner ring 312 serves as the fixed fulcrum of the valve plate 313. One end of the valve plate 313 is hinged to this, and the other end is hinged to the inner area of the crescent holes 318 on the rotating inner ring 312 through the crescent connecting rod 316. When the rotating inner ring 312 rotates, the contour change of the crescent holes 318 is transmitted to the valve plate 313 through the connecting rod mechanism, driving the valve plate 313 to swing around the hinge point of the support ring 315, thereby realizing the opening or closing action of the iris. The above-mentioned valve plate 313 opening and closing structure is a known mature technology, and this utility model will not describe it in detail.
[0023] The support ring 315 is provided with a through hole 319 that matches the diameter of the heating base. When the valve plate 313 is open, it surrounds the through hole 319 to form a circular hole with the same diameter. When closed, it surrounds the through hole 319 to form a disc. When the valve plate 313 is open, the support ring 315 can pass directly through the heating base 2 and descend below the heating base 2.
[0024] The telescopic support column 314 includes an inner column 3141, an outer column 3142, and a compression spring 3143. The inner column 3141 is vertically connected to the bottom of the settling tank 113. The outer column 3142 is sleeved above the inner column 3141 and can slide. The top of the outer column 3142 is connected to the bottom surface of the fixed outer ring 311. The compression spring 3143 is located inside the inner column 3141 and connected to the outer column 3142. The telescopic support column 314 adopts the structural design of inner column 3141, outer column 3142, and compression spring 3143 to achieve stable support and automatic reset function of the iris opening and closing component. The inner column 3141 is vertically fixed to the bottom of the settling tank 113. The bottom of the settling tank 113 serves as a guide support. The outer column 3142 is sleeved on the inner column 3141 and can slide freely, and is connected to the fixed outer ring 311. The compression spring 3143 is placed inside the inner column 3141 and connected to the outer column 3142. When the kettle is placed, the outer column 3142 is pressed down and the compression spring 3143 causes the iris opening and closing component to descend and open the heating base 2. After the kettle is removed, the spring rebounds and pushes the outer column 3142 up, causing the iris opening and closing component to reset and seal, ensuring the stability of the vertical guiding movement. At the same time, it realizes automatic reset without power. It has the advantages of simple structure, high reliability and long service life, and effectively solves the pain points of the traditional tea bar machine heating base 2 being prone to dust accumulation and requiring manual operation.
[0025] The machine body 1 also includes an operation panel 6, which is located at the top of the machine body 1. The operation panel 6 integrates function buttons or touch interface for temperature adjustment, heating control, mode selection, etc., so that users can operate the tea bar machine intuitively and conveniently. Its position at the top of the machine body 1 is ergonomic, so that users can easily adjust it without bending over when operating it while standing. At the same time, the operation panel 6 is connected to the internal control system and can display information such as water temperature and working status in real time, enhancing the convenience of use.
[0026] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
