Technical Field

[0001] This utility model relates to the technical field of coffee brewing devices, and in particular to a coffee filter cup and pour-over coffee pot set. Background Technology

[0002] Currently, there are more and more ways to brew coffee, such as cold brew and hot water brewing of coffee grounds. During the brewing process, coffee grounds need to be filtered out. Drinking filtered coffee tastes better. Existing coffee brewing devices use a drip method to let water flow through the coffee grounds, reducing the number of brewing times, and the water slowly flows through the coffee grounds.

[0003] In the prior art, such as the Chinese utility model patent publication number CN210643714U, a coffee filter cup is disclosed, including a cup body. The bottom of the cup body has an upward protrusion, and filter paper is hot-stamped onto the inner bottom of the cup body. The cup body has an outward-facing annular horizontal edge at the rim, and a support ring is fitted around the outside of the cup body below the annular horizontal edge. The upper surface of the support ring is in contact with the lower surface of the annular horizontal edge, and the inner peripheral wall of the support ring is in close contact with the outer peripheral wall of the cup body. However, the bottom of this coffee filter cup is difficult to clean and is prone to bacterial growth. Utility Model Content

[0004] One objective of this application is to provide a coffee filter cup and pour-over coffee maker set that is easy to clean.

[0005] The technical solution adopted in this application is: a coffee filter cup, including a cup body and a filter element, a first opening is provided at the bottom of the cup body, the filter element is detachably disposed on the first opening, the filter element is provided with a filter channel, and a sealing element is provided between the cup body and the filter element.

[0006] Compared with the prior art, the advantages of this application are that the filter element is designed to be detachable, which makes it easy to disassemble the filter element for cleaning, especially the filter channel on the filter element is easier and cleaner to clean; the sealing element is used to improve the sealing between the cup body and the filter element, preventing coffee extract from leaking out from the gap between the cup body and the filter element.

[0007] In some embodiments of this application, the filter element has a first groove on its side, and the seal element is located on the first groove. The design of the first groove facilitates the positioning and installation of the seal element, and also prevents the seal element from falling off during the assembly and disassembly of the filter element.

[0008] In some embodiments of this application, the cross-section of the seal is C-shaped, T-shaped, or V-shaped. C-shaped, T-shaped, or V-shaped seals can produce greater deformation, and while ensuring a good seal, they are suitable for frequent disassembly and assembly of the filter element, resulting in less wear and a longer service life.

[0009] In some embodiments of this application, the cup body comprises an inner wall and an outer wall from the inside out, with the upper end of the inner wall connected to the upper end of the outer wall, and the lower end of the inner wall connected to the lower end of the outer wall. This double-layered design improves the structural strength of the cup body.

[0010] Furthermore, a cavity is formed between the inner and outer walls; the inner wall is generally inverted conical; the outer wall is generally cylindrical. The cavity can delay heat loss from the side wall of the cup, so that the drip-filtered coffee can still maintain a high temperature, ensuring the coffee flavor, and the user will not be burned when handling the outer wall after or during use; the inverted conical shape of the inner wall makes it easy to fit the filter paper and can guide the water flow downwards and concentrate, which is convenient for drip-filtering.

[0011] In some embodiments of this application, a protrusion is provided at the center of the upper surface of the filter element.

[0012] In some embodiments of this application, a base is also included, the upper surface of which mates with the lower surface of the cup body; the base has a second opening, the projection of the second opening onto the horizontal plane at least partially coinciding with the projection of the first opening onto the horizontal plane. One side of the base is used to connect to the coffee pot, and the other side is used to place the cup body, thus connecting the cup body to the coffee pot; the second opening is used to ensure that the filter channel is in communication with the coffee pot.

[0013] Furthermore, a base pad is provided on the bottom surface of the cup body, and the upper surface of the base is at least partially toothed, with the lower surface of the base pad engaging with the upper surface of the base. This base pad design enhances the structural strength of the cup body's bottom, and the combination of the base pad and the toothed upper surface of the base makes the cup more stable, preventing it from sliding freely and reducing the risk of it falling.

[0014] Furthermore, the lower surface of the base is provided with a protruding limiter, which can be locked onto the opening of the coffee pot to prevent the base from slipping off relative to the coffee pot.

[0015] In some embodiments of this application, the upper surface of the filter element is provided with at least one flow channel, and the filter channel is located at the bottom surface of the flow channel. The design of the flow channel allows coffee liquid to concentrate in the flow channel, making it easier to discharge from the filter channel and reducing coffee liquid residue on the filter element.

[0016] A pour-over coffee maker set includes a coffee filter cup, filter paper, and a pot body disposed at the bottom of the cup body, wherein the filter paper is disposed on the cup body; the filter channel connects the cup body and the pot body. Attached Figure Description

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Example 1:

[0024] This embodiment provides a coffee filter cup, such as... Figure 1 , Figure 2 As shown, it includes a cup body 1 and a filter element 2. The bottom of the cup body 1 is provided with a first opening 3. The filter element 2 is detachably mounted on the first opening 3. The filter element 2 is provided with a filter channel 4. A sealing element 5 is provided between the cup body 1 and the filter element 2.

[0025] The traditional cup body 1 and filter element 2 are integrated into one structure. The opening of the cup body 1 is limited, making it difficult to clean the bottom of the cup body 1. In particular, the bottom of the cup body 1 has a channel for coffee extract, which can easily leave residue. The filter element 2 is designed to be detachable, making it easy to remove and clean. In particular, it is easier and cleaner to clean the filter channel 4 on the filter element 2. The sealing element 5 is used to improve the seal between the cup body 1 and the filter element 2, preventing coffee extract from leaking out of the gap between the cup body 1 and the filter element 2.

[0026] In this embodiment, the sealing element 5 is made of elastic rubber material and is sleeved on the filter element 2; a baffle plate 17 extending towards the center is provided on the first opening 3, and the lower surface of the filter element 2 is in contact with the baffle plate 17 to prevent the filter element 2 from falling downward and to ensure reliable installation of the filter element 2; the baffle plate 17 is located at the bottom of the inner wall 7 and the baffle plate 17 and the inner wall 7 are an integral structure.

[0027] To ensure the reliability of the seal 5, the seal 5 has a C-shaped, T-shaped, or V-shaped cross-section. A first groove 6 is provided on the side of the filter element 2, and the seal 5 is located on the first groove 6. Part of the seal 5 extends beyond the first groove 6, ensuring the seal 5 fits snugly against the inner wall 7, thereby guaranteeing the sealing effect. In this embodiment, the seal 5 has a C-shaped cross-section. Traditional O-rings have limited deformation capacity. While ensuring the sealing effect, the pressure from both sides is high. When the filter element 2 needs frequent disassembly and assembly, it is prone to wear, affecting the sealing effect, resulting in a short service life and increased maintenance costs. However, the C-shaped seal 5 can generate a larger deformation, ensuring the sealing effect while being suitable for frequent disassembly and assembly of the filter element 2, with less wear and a longer service life. The design of the first groove 6 facilitates the positioning and installation of the seal 5, and prevents it from falling off during the disassembly and assembly of the filter element 2. Of course, the cross-section of the sealing element 5 can also be T-shaped or V-shaped. When using a T-shape, the T-shape is placed horizontally, with the horizontal side of the T-shape located on the first groove 6 and in contact with the filter element 2, and the vertical side of the T-shape in contact with the cup body 1. When using a V-shape, one side of the V-shape is located on the first groove 6 and in contact with the filter element 2, and the other side is in contact with the cup body 1.

[0028] In this embodiment, the C-shaped opening faces the center line of the seal 5, so that both ends of the C-shaped opening contact the first groove 6, achieving a two-stage seal with good sealing effect.

[0029] To ensure the reliability of the cup body 1, the cup body 1 includes an inner wall 7 and an outer wall 8 from the inside out. The upper end of the inner wall 7 is connected to the upper end of the outer wall 8, and the lower end of the inner wall 7 is connected to the lower end of the outer wall 8. The first opening 3 is provided on the inner wall 7. The double-layer design of the cup body 1 can improve the structural strength of the cup body 1. Especially when the cup body 1 is made of glass, the inner wall 7 is in contact with hot water, and the alternation of hot and cold temperatures causes large temperature differences, making it prone to breakage. Most of the broken glass fragments remain inside the outer wall 8, making it easy to clean.

[0030] To improve heat retention, a cavity is formed between the inner wall 7 and the outer wall 8. The inner wall 7 is generally inverted conical, while the outer wall 8 is generally cylindrical. The lower part of the inner wall 7 is bent, which improves its structural strength and enhances its fit with the filter element 2. During drip brewing, besides heat loss from the top, the coffee experiences the greatest contact with the side wall of the cup body 1, making it a prime location for heat loss. The cavity slows down heat loss from the side wall of the cup body 1, ensuring the brewed coffee maintains a relatively high temperature and preserves its flavor. Users will not be burned when handling the outer wall 8 during or after use. The inverted conical shape of the inner wall 7 facilitates the fit of the filter paper and directs water flow downwards to a concentrated point, making drip brewing easier. The cylindrical shape of the outer wall 8 enhances the overall aesthetics.

[0031] To facilitate the placement of the cup body 1, a base 9 is also included, the upper surface of which mates with the lower surface of the cup body 1. The base 9 has a second opening 10, the projection of which onto the horizontal plane at least partially overlaps with the projection of the first opening 3 onto the horizontal plane. The upper surface of the base 9 is in contact with the lower surface of the cup body 1. One side of the base 9 is used to connect to the coffee pot, and the other side is used to place the cup body 1, thus connecting the cup body 1 to the coffee pot. The second opening 10 ensures that the filter channel 4 is connected to the coffee pot.

[0032] In this embodiment, the projection of the second opening 10 on the horizontal plane completely coincides with the projection of the first opening 3 on the horizontal plane.

[0033] To ensure stable placement between the cup body 1 and the base 9, a base pad 11 is provided on the bottom surface of the cup body 1, and at least part of the upper surface of the base 9 is toothed. The lower surface of the base pad 11 mates with the upper surface of the base 9. In this embodiment, the entire upper surface of the base 9 is toothed. The design of the base pad 11 enhances the structural strength of the bottom of the cup body 1. Simultaneously, the base pad 11, in conjunction with the toothed upper surface of the base 9, makes the cup body 1 more stable, preventing it from sliding freely and reducing the risk of it falling. Of course, the upper surface of the base 9 can also be wavy; as long as the base 9 and the base pad 11 have a concave-convex fit, the cup body 1 can be placed stably.

[0034] In this embodiment, the toothed shape on the upper surface of the base 9 surrounds the center of the base 9, which is aesthetically pleasing and prevents the cup 1 from moving on the horizontal surface of the base 9, thus ensuring the stability of the cup 1. The bottom pad 11 is arranged in a ring around the first opening 3, so that the weight of the cup 1 can be evenly distributed on the bottom pad 11, and the contact area between the bottom pad 1 and the base 9 is large.

[0035] To ensure the base 9 can be stably placed on the coffee pot, a raised stop 12 is provided on the lower surface of the base 9. The raised stop 12 can be engaged with the opening of the coffee pot to prevent the base 9 from slipping off relative to the coffee pot. In this embodiment, the raised stop 12 is annular.

[0036] To ensure the effective flow of coffee liquid into the coffee pot, the upper surface of the filter element 2 is provided with at least one flow channel 13, and the filter channel 4 is located on the bottom surface of the flow channel 13. The design of the flow channel 13 allows the coffee liquid to concentrate in the flow channel 13, making it easier to discharge from the filter channel 4 and reducing coffee liquid residue on the filter element 2.

[0037] In this embodiment, the upper surface of the filter element 2 is provided with two spaced-apart flow channels 13, which are concentric rings.

[0038] To ensure the coffee liquid enters the coffee pot effectively, a protrusion 14 is provided at the center of the upper surface of the filter element 2. The center of the upper surface of the filter element 2 is where coffee liquid is most likely to remain. The protrusion 14 prevents the coffee liquid from concentrating in the center and guides it towards the flow channel 13. It also prevents the filter paper from sticking to the filter element 2 during use, increasing filtration efficiency and allowing the filtered liquid to have more contact with air, thus improving the taste.

[0039] Example 2:

[0040] This embodiment provides a pour-over coffee maker set, such as Figure 3 , Figure 4 As shown, the device includes a coffee filter cup as described in Embodiment 1, a filter paper 15, and a pot body 16 disposed at the bottom of the cup body 1. The filter paper 15 is disposed on the cup body 1; the filter channel 4 connects the cup body 1 and the pot body 16. In use, coffee powder is placed on the filter paper 15, and hot water is poured in for brewing. The water flows through the coffee powder for extraction. The filter paper 15 blocks the coffee powder, and the extracted liquid passes through the filter paper 15 into the cup body 1 and drips into the pot body 16 through the filter channel 4.

[0041] The protruding limit 12 is inserted through the opening of the pot body 16, so that the movement of the base 9 will be blocked by the pot body 16.

[0042] In this embodiment, the filter paper 15 includes a folded skirt 18 and a flat bottom 19 at the bottom of the skirt 18. The skirt 18 and the flat bottom 19 form a filter cavity for holding coffee powder. The folded design of the skirt 18 increases the area and improves the extraction efficiency. During brewing, the water flow can expand the skirt 18, resulting in a better fit with the cup body 1. Traditional filter paper is inverted conical with a pointed bottom and a small area. At the same time, the water flow is concentrated at the pointed top, which is prone to over-extraction. The design of the flat bottom 19 increases the area and improves the extraction efficiency. The water flow is concentrated on the flat surface, which can reduce the probability of over-extraction in a certain area. The protrusion 14 cooperates with the flat bottom 19 to support the center of the flat bottom 19 and prevent the water flow from concentrating at the center of the flat bottom 19 and causing it to protrude downwards and break.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
