Description

Technical Field

[0001] This utility model relates to a coffee brewing device. Background Technology

[0002] Existing coffee brewing devices generally consist of a brewing head, a sealing ring, and a brewing base. The brewing head and base are locked together to allow coffee to flow and brew. In practical applications, the brewing head and base often experience repeated friction and contact at the connection point. Due to long-term pressure and friction, wear and tear can easily occur. This wear not only gradually weakens the seal between the brewing head and base, leading to problems such as poor coffee flow or leakage, but may also affect the quality of the coffee and even shorten the overall lifespan of the equipment.

[0003] In addition, due to the internal pressure and high temperature of coffee liquid during the brewing process, the wear-resistant design of the brewing head connection in the existing technology is not perfect and cannot effectively deal with the wear problem caused by long-term friction, which increases the maintenance cost and replacement frequency of the equipment.

[0004] To address the aforementioned technical issues, this innovative design incorporates a first locking block at a gap on the inner wall of the brewing head facing the connecting cavity, with a metal wear-resistant sheet on its surface. Simultaneously, a second locking block is positioned at a gap on the outer wall of the brewing base near the top. When the brewing head and brewing base are locked together, the second locking block presses against the metal wear-resistant sheet. Utilizing the excellent wear resistance of the metal wear-resistant sheet, wear caused by locking friction is effectively reduced, thus maintaining the integrity and stability of the sealing ring connection. This ensures that the coffee machine maintains excellent sealing performance and overall performance even during long-term use. Utility Model Content

[0005] The purpose of this invention is to provide a coffee machine brewing device that effectively reduces wear caused by clamping friction and ensures that the coffee machine can maintain a good sealing effect during long-term use.

[0006] The purpose of this utility model is achieved as follows:

[0007] A coffee maker brewing device includes a brewing head, a sealing ring, and a brewing base. The brewing head has a downward-facing connecting cavity and a water outlet communicating with the connecting cavity. The sealing ring is disposed on the brewing head and located inside the connecting cavity.

[0008] The inner wall of the brewing head is provided with first locking blocks at intervals facing the connecting cavity, the gap between the first locking blocks forms an entrance, and the surface of the first locking blocks is provided with metal wear-resistant plates.

[0009] The brewing base is provided with a brewing cavity with an upward opening. The brewing base is provided with a coffee liquid outlet communicating with the brewing cavity. The outer wall of the brewing base near its top is provided with second clamping blocks at intervals;

[0010] The brewing head and the brewing base are clamped tightly with each other. The top of the brewing head abuts against the sealing ring, and at the same time, the second clamping block presses the metal wear-resistant sheet.

[0011] The first clamping block arranged on the inner wall of the brewing head is covered with a metal wear-resistant sheet. By utilizing the high wear-resistant performance of the metal material, the friction loss caused by the clamping of the brewing head and the brewing base is effectively reduced, thereby prolonging the service life of the device.

[0012] The top of the brewing head abuts against the sealing ring, and the second clamping block on the brewing base applies pressure to the metal wear-resistant sheet to ensure that the brewing head and the brewing base are clamped tightly with each other, and a tight contact is formed between the sealing ring and the connection cavity. Thus, excellent sealing performance is maintained during long-term use, preventing problems such as water leakage or coffee liquid leakage.

[0013] By improving the overall wear resistance and sealing performance, the replacement and maintenance frequencies caused by long-term wear are reduced, thereby reducing the equipment maintenance cost and enhancing the user experience.

[0014] The stable and reliable sealing effect and wear-resistant design ensure that the coffee liquid can flow out evenly during the brewing process, which helps to maintain the stability and quality of coffee brewing.

[0015] The object of the present utility model can also be solved by adopting the following technical measures:

[0016] Furthermore, the metal wear-resistant sheet includes a transverse portion and a vertical portion. The vertical portions are respectively arranged at the ends of the transverse portion to form a "C"-shaped metal wear-resistant sheet.

[0017] The metal wear-resistant sheet improves the rigidity of the first clamping block, so that during long-term friction and repeated clamping, the wear speed is significantly reduced, and the service life of the brewing device is prolonged.

[0018] Furthermore, the first clamping block is provided with a socket, and the transverse portion is inserted into the corresponding socket and clamped tightly, so as to fix the metal wear-resistant sheet on the first clamping block.

[0019] By opening a socket on the first clamping block and inserting the transverse portion of the metal wear-resistant sheet into the corresponding socket and clamping tightly, the reliable fixation of the wear-resistant sheet and the clamping block is achieved, preventing loosening or falling off due to vibration or external force.

[0020] The clamping fixation forms an integrated structure, enhancing the overall impact resistance and wear resistance ability, and ensuring the durability of the brewing device during long-term use.

[0021] The secure installation of the wear-resistant plate allows it to stably provide support and wear resistance under the pressure of the second locking block, thereby ensuring a tight fit between the sealing ring and the inner wall of the brewing head and preventing water leakage.

[0022] The snap-fit ​​design of the socket and the horizontal part makes the installation of the metal wear-resistant plate simple and reliable, which helps to improve production efficiency and assembly quality, while also facilitating later maintenance and replacement.

[0023] Furthermore, the brewing head is a die-cast aluminum brewing head.

[0024] Die-cast aluminum has excellent thermal conductivity, which helps to dissipate heat evenly and improve the accuracy of temperature control during brewing, thereby improving the extraction effect and flavor stability of coffee.

[0025] Furthermore, the metal wear-resistant sheet is a stainless steel sheet.

[0026] By using stainless steel wear-resistant metal sheets, their excellent wear and corrosion resistance properties are fully utilized to effectively reduce wear caused by long-term friction, extend the service life of key components, and maintain sealing performance.

[0027] The combination of die-cast aluminum brewing head and stainless steel wear-resistant sheet not only ensures the lightweight and high strength of the brewing head, but also provides a good sealing effect under the pressing action of the second retaining block, thereby improving the overall brewing quality and work efficiency of the coffee machine.

[0028] Furthermore, it also includes a shower head and a water distribution base, wherein the water distribution base has an annular water groove, and at least three drain outlets are spaced apart at the bottom of the water distribution base corresponding to the annular water groove;

[0029] The water distribution seat is set on the brewing head, and the water outlet is connected to the annular water tank.

[0030] The shower head has drainage holes spaced apart, and the shower head is located on the rinsing head and below the water distribution base.

[0031] The ring-shaped water tank of the water distribution seat is connected to the water outlet of the brewing head, so that the water entering the tank can be evenly distributed throughout the entire ring area. Then, through the drainage holes spaced on the shower blade, the water is evenly delivered to the coffee grounds, which helps to achieve a comprehensive and uniform coffee extraction and enhance the coffee flavor.

[0032] The proper configuration of the water distribution base and the shower head not only ensures even water distribution and efficient drainage, but also improves the continuity and balance of the brewing water flow, further enhancing the extraction effect of coffee and ensuring that every cup of coffee can present its best flavor.

[0033] The beneficial effects of this utility model are as follows:

[0034] This invention features a metal wear-resistant sheet covering the surface of the first locking block on the inner wall of the brewing head. By utilizing the high wear resistance of the metal material, frictional losses caused by the locking of the brewing head and the brewing base are effectively reduced, thereby extending the service life of the device.

[0035] In this invention, the top of the brewing head rests against the sealing ring, and pressure is applied to the metal wear-resistant sheet by the second locking block on the brewing base, ensuring that the brewing head and the brewing base are locked together, and that the sealing ring and the connecting cavity form a tight contact, thereby maintaining excellent sealing performance during long-term use and preventing water leakage or coffee leakage.

[0036] This invention achieves reliable fixation between the wear-resistant sheet and the locking block by opening an insertion port on the first locking block and inserting the transverse part of the metal wear-resistant sheet into the corresponding insertion port and locking it. This prevents the wear-resistant sheet from loosening or falling off due to vibration or external force. Moreover, the locking and fixing form an integrated structure, which improves the overall impact resistance and wear resistance, and ensures the durability of the brewing device during long-term use.

[0037] In this invention, the annular water tank of the water distribution base is connected to the water outlet of the brewing head, so that the water flowing into the water tank can be evenly distributed throughout the entire annular area. Then, through the drainage holes spaced apart on the shower blade, the water is evenly delivered to the coffee powder, which helps to achieve comprehensive and uniform coffee extraction and enhance the coffee flavor.
