Description

Technical Field

[0001] The present application relates to the technical field of moka pots, and in particular to a moka pot with good sealing performance. Background Art

[0002] The Moka pot, a classic coffee brewing device, is widely popular for its simple structure and ease of use. However, for traditional Moka pots, the lower pot body must be sealed because it uses high pressure to transfer hot water to the upper pot body.

[0003] Conventional moka pots, such as the pressurized moka pot proposed in announcement number CN216724179U, use a third sealing ring to press-seal the high-pressure environment of the lower pot body. However, this conventional sealing method, when used at high intensity, will inevitably reduce the sealing performance of the thinner sealing ring after long-term use, thereby affecting the coffee extraction efficiency. Therefore, a method is proposed that can effectively seal the lower pot body and the upper pot body.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, the present application provides a moka pot with good sealing performance to solve one of the above technical problems.

[0006] The technical solution adopted by the present application to solve its technical problem is a moka pot with good sealing performance, including: an upper pot body, used to store coffee liquid, and a first connecting part is fixedly provided on the bottom of the upper pot body; a lower pot body, used to store hot water, and a second connecting part is provided at the opening of the lower pot body; a coffee powder tank, placed inside the opening of the lower pot body; a rubber sealing block, including a third connecting part, the third connecting part and the second connecting part are interconnected, and the first connecting part is provided above the rubber sealing block; the rubber sealing block can simultaneously connect the upper pot body and the lower pot body and perform effective sealing.

[0007] In some embodiments, the rubber sealing block is provided with two circles of protrusions, and the inner side of the first connecting portion is provided with a recessed portion that cooperates with the protrusions.

[0008] In some embodiments, the third connection portion and the second connection portion are both provided with threads, and the third connection portion and the second connection portion are threadedly connected.

[0009] In some embodiments, a first step is formed on the top of the second connecting portion, and an outer edge of the coffee powder trough is placed on the first step.

[0010] In some embodiments, the rubber sealing block is formed with an abutting portion abutting against the top of the second connecting portion and the top of the coffee powder groove, and the abutting portion is pressed by the bottom of the upper kettle body.

[0011] In some embodiments, the rubber sealing block is made of fluoroelastomer, and the Shore hardness of the rubber sealing block ranges from 60A to 80A.

[0012] In some embodiments, the rubber sealing block is formed with a second step, the bottom of the first connecting portion abuts against the top surface of the second step, and the inner wall of the first connecting portion abuts against the outer wall of the rubber sealing block.

[0013] The rubber sealing block can be threadedly connected with the lower kettle body, and the abutting portion can simultaneously press the top of the lower kettle body and the top of the coffee powder groove after the thread connection is completed, so that the coffee wind is sealed. The threadedly connected rubber sealing block is more stable than the conventional press-connected sealing ring, and the large coverage range of the rubber sealing block prevents the Moka kettle from being press-connected for a long time to cause a decrease in sealing performance, thereby prolonging the service life of the Moka kettle. Meanwhile, the upper kettle body is connected and inserted with the rubber sealing block through the deformation of the rubber, and is fixed through the convex portion, thereby simplifying the installation process of the upper kettle body and optimizing the use experience.

DETAILED DESCRIPTION

[0019] With reference to the drawings and based on the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the protection scope of the present application. In addition, the technical solutions of various embodiments can be combined with each other, but the combination of the technical solutions should be based on the fact that a person of ordinary skill in the art can realize the combination, and when the combination of the technical solutions is contradictory or unachievable, it should be considered that the combination of the technical solutions does not exist and is not within the protection scope of the present application.

[0020] In the embodiments of the present application, as shown in Figures 1-3 The present application provides a mocca pot with good sealing performance, which mainly comprises: an upper pot body 1 for storing coffee liquid, a first connecting part 11 fixedly arranged at the bottom of the upper pot body 1; a lower pot body 2 for storing hot water, a second connecting part 21 arranged at the opening of the lower pot body 2; a coffee powder groove 3 placed inside the opening of the lower pot body 2; a rubber sealing block 4 comprising a third connecting part 41, the third connecting part 41 is connected with the second connecting part 21, and the first connecting part 11 is arranged above the rubber sealing block 4; the rubber sealing block 4 can simultaneously connect the upper pot body 1 and the lower pot body 2 and effectively seal.

[0021] Specifically, when the rubber sealing block 4 is installed on the second connecting part 21, most of the rubber sealing block 4 is wrapped outside and on top of the second connecting part 21, and can press the outer edge of the coffee powder groove 3, so that the coffee powder groove 3 does not shake when placed at the opening of the lower pot body 2, and the sealing effect is guaranteed, and the upper pot body 1 is pressed, further guaranteeing the connection performance of the rubber sealing block 4.

[0022] Some preferred / modified embodiments based on the above embodiments will be further described below. The following embodiments can be selected or combined.

[0023] As shown in Figure 3 The inner side of the first connecting part 11 is provided with a recess 111 matched with the convex part 42, so that the first connecting part 11 has a certain connection strength when arranged on the rubber sealing block 4, not only relying on the elastic potential of the rubber to fix, preventing the lower pot from falling off when the mocca pot is lifted by the user.

[0024] As a preferred, in order to enhance the connection strength of the rubber sealing block 4 arranged on the second connecting part 21, and guarantee that the third connecting part 41 and the second connecting part 21 are both provided with threads, the third connecting part 41 is threadedly connected with the second connecting part 21.

[0025] Specifically, in order to ensure the sealing performance of the rubber sealing block 4 on the lower kettle body 2, a first step 211 is formed on the top of the second connecting part 21, and the outer edge of the coffee powder groove 3 is placed on the first step 211. The rubber sealing block 4 is formed with an abutting part 43 which abuts on the top of the second connecting part 21 and the top of the coffee powder groove 3 at the same time, and the abutting part 43 is crimped by the bottom of the upper kettle body 1.

[0026] As a preferred, the rubber sealing block 4 is made of fluororubber material, and the Shore hardness of the rubber sealing block 4 ranges from 60A to 90A. The fluororubber material can ensure that the rubber sealing block 4 does not deform when it is subjected to high temperature, and to some extent, it can reduce the heat transfer. The higher Shore hardness facilitates the processing of threads for screwing with the second connecting part 21, so that the fluororubber retains a certain elasticity to connect with the first connecting part 11.

[0027] Referring to Figure 3 As shown in the figure, the outer side of the rubber sealing block 4 is formed with a second step 44, the bottom of the first connecting part 11 abuts on the top surface of the second step 44, and the inner wall of the first connecting part 11 abuts on the outer wall of the rubber sealing block 4. The rubber sealing block 4 has a certain elasticity, and the first connecting part 11 is inserted on the second step 44 by extruding the rubber sealing block 4, forming an outer ring composed of the outer wall of the first connecting part 11 and the outer wall of the second step 44. As a preferred, the first connecting part 11 can be made of a material with poor heat conduction performance, so that the outer ring can serve as a holding part to prevent the user from being scalded when he / she is difficult to lift the moka pot with one arm due to small strength.
