Description

Technical Field

[0001] This utility model relates to the field of coffee stand technology, specifically to a hand-drip coffee auxiliary stand with a quantitative water injection function. Background Technology

[0002] Traditional pour-over coffee brewing relies heavily on manual water pouring techniques, demanding extremely high precision in water flow control, volume, and pouring trajectory. However, most existing pour-over coffee stands only provide basic filter cup support, requiring manual control of the pouring process. This results in insufficient water flow stability and inconsistent pouring, directly impacting the extraction quality of the coffee. While some automated pouring devices exist, these typically employ fixed designs, resulting in complex structures and bulky sizes. This not only increases the difficulty of use and storage but also limits the flexibility for users to adjust pouring strategies based on the characteristics of different coffee beans. Furthermore, traditional metered pouring devices often rely on electric pumps or electronic flow meters, which are not only costly but also unusable in environments without power, failing to meet the needs of diverse brewing scenarios.

[0003] While some automated water-pouring devices exist on the market, current technology falls short in terms of comprehensive optimization regarding water temperature maintenance, pulsed pouring simulation, and portability, failing to fully replace the hand-drip technique of professional baristas. Therefore, there is an urgent need for a simple, highly reliable, and electrically powered metering water-pouring stand that ensures precise control while enhancing the user experience.

[0004] Therefore, it is necessary to invent a hand-drip coffee auxiliary stand with a metered water dispensing function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a hand-drip coffee auxiliary stand with a quantitative water injection function. The quantitative water injection is achieved through the cooperation of the support plate and the water injection mechanism, which solves the problem that traditional quantitative water injection devices in the prior art mostly rely on electric pumps or electronic flow meters, which are not only costly but also cannot be used in environments without power.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hand-drip coffee auxiliary support with a quantitative water injection function, comprising a support plate, a water injection mechanism fixedly connected to the surface of the support plate, the water injection mechanism including a water injection cup fixedly connected to the surface of the support plate, a first connecting pipe fixedly connected to the outside of the water injection cup, a water outlet pipe installed inside the first connecting pipe, a transfer cylinder fixedly connected to the top of the first connecting pipe, an equilateral triangle set inside the transfer cylinder, a squeeze wheel fixedly connected to the corner of the equilateral triangle, the water outlet pipe fitting against the left side of the inside of the transfer cylinder, a hollow frame rotatably connected to the top of the transfer cylinder, and the equilateral triangle driving the squeeze wheel to periodically squeeze the water outlet pipe through rotation to achieve quantitative water flow control.

[0007] Preferably, a connecting pipe is fixedly connected inside the hollow frame, and the bottom end of the connecting pipe is interference-fitted with the top end of the water outlet pipe. The interference fit ensures the water circuit is sealed and prevents liquid leakage during the water injection process.

[0008] Preferably, a filter cup is inserted into the surface of the support plate, and two sets of mounting slots are provided at the bottom of the support plate for installing subsequent parts.

[0009] Preferably, a support frame is snapped into the bottom of the mounting slot, and a counterweight is fixedly connected to the bottom of the mounting slot. The counterweight increases the overall stability of the support and prevents it from tipping over during the brewing process.

[0010] Preferably, a rotating handle is connected to the center of the transfer cylinder. The outer side of the rotating handle is fixedly connected to the inner side of the equilateral triangle. Asbestos is sleeved on the outer side of the rotating handle. The asbestos wrapping layer insulates against heat conduction and prevents burns to the user during operation.

[0011] Preferably, a rotating block is fixedly connected to the top of the hollow frame, and several sets of inner holes are opened on the outer side wall of the water outlet pipe. The inner holes cooperate with the elastic ball to facilitate the limiting of rotation.

[0012] Preferably, a number of sets of elastic balls are fixedly connected inside the connecting tube. The positions of the elastic balls and the inner hole are corresponding. The tactile sensation generated when the elastic balls rotate with the inner hole can prompt the user within a fixed angle, thereby improving the user experience.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By cooperating with the support plate and the water injection mechanism, the equilateral triangle drives the extrusion wheel to periodically squeeze the water outlet pipe, achieving precise quantitative water injection control. The water injection volume can be directly adjusted by rotating the handle. The operation is intuitive and has high repeatability. The combination of the counterweight at the bottom of the support plate and the detachable support frame ensures overall stability while also being portable. The asbestos wrapping layer on the outside of the handle effectively isolates high temperature conduction, solving the safety hazard of hot metal parts. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5The illustrated pour-over coffee support with a metered water dispensing function includes a support plate 1. A water dispensing mechanism 2 is fixedly connected to the surface of the support plate 1. The water dispensing mechanism 2 includes a water cup 201 fixedly connected to the surface of the support plate 1. A first connecting pipe 202 is fixedly connected to the outside of the water cup 201. A water outlet pipe 206 is installed inside the first connecting pipe 202. A transfer cylinder 203 is fixedly connected to the top of the first connecting pipe 202. An equilateral triangle 204 is arranged inside the transfer cylinder 203. A squeeze wheel 205 is fixedly connected to the corner of the equilateral triangle 204. The water outlet pipe 206... 6 is attached to the inside left side of the transfer cylinder 203. The top of the transfer cylinder 203 is rotatably connected to a hollow frame 207. The equilateral triangle frame 204 drives the extrusion wheel 205 to periodically extrude the water outlet pipe 206 to achieve quantitative water flow control. The hollow frame 207 is fixedly connected to a connecting pipe 208. The bottom end of the connecting pipe 208 is interference-fitted to the top end of the water outlet pipe 206. The interference fit ensures the water circuit is sealed and prevents liquid leakage during water injection. A filter cup 3 is inserted into the surface of the support plate 1. Two sets of mounting grooves 4 are opened at the bottom end of the support plate 1. The mounting grooves 4 are used to install subsequent parts.

[0025] Refer to the instruction manual appendix Figure 1-5 A support frame 5 is snapped into the bottom of the mounting slot 4, and a counterweight 10 is fixedly connected to the bottom of the mounting slot 4. The counterweight 10 increases the overall stability of the support and prevents it from tipping over during the brewing process. A rotating handle 6 is connected to the center of the central rotating cylinder 203. The outer side of the rotating handle 6 is fixedly connected to the inner side of the equilateral triangle frame 204. Asbestos is sleeved on the outer side of the rotating handle 6. The asbestos wrapping layer insulates heat conduction and prevents burns during user operation. A rotating block 7 is fixedly connected to the top of the hollow frame 207. Several sets of inner holes 8 are opened on the outer wall of the water outlet pipe 206. The inner holes 8 cooperate with the elastic balls 9 to facilitate the limiting of rotation. Several sets of elastic balls 9 are fixedly connected inside the connecting pipe 208. Corresponding to the position of the inner hole 8, the tactile sensation generated by the rotation of the elastic ball 9 and the inner hole 8 within a fixed angle prompts the user, improving the user experience. Through the cooperation of the support plate 1 and the water injection mechanism 2, the equilateral triangle 204 drives the extrusion wheel 205 to periodically extrude the water outlet pipe 206, achieving precise quantitative water injection control. The water injection volume can be directly adjusted by rotating the handle 6. The operation is intuitive and has high repeatability. The counterweight 10 at the bottom of the support plate 1 is combined with the detachable support frame 5, ensuring overall stability while also taking into account portability. The asbestos wrapping layer on the outside of the handle 6 effectively isolates high temperature conduction, solving the safety hazard of hot metal parts.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5When in use, hot water is poured into the water cup 201, and the water flows through the first connecting pipe 202 into the water outlet pipe 206. When the handle 6 is manually rotated, the equilateral triangle 204 rotates synchronously, and the squeezing wheels 205 at its three corners squeeze the water outlet pipe 206 in sequence. Each 120° rotation completes one metered water dispensing. The water flow rate can be adjusted by controlling the rotation speed. The top of the water outlet pipe 206 is connected to the connecting pipe 208 through an interference fit. The hollow frame 207 can rotate freely around the central rotating cylinder 203, driving the rotating block 7 to change the water outlet angle, so that it can rotate without affecting the water filling of the water cup 201. When the filter cup 3 is placed on the support plate 1, its weight is transferred to the support frame 5 through the mounting groove 4. The additional weight provided by the counterweight 10 ensures that the brewing process is stable and does not tilt. During the entire water filling process, the asbestos wrapping layer effectively blocks the heat transfer from the high-temperature components to the operating end of the rotating handle 6.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
