AI Technical Summary
In the long-term use of existing coffee machine evacuation valves, the service life is short and the adjustment performance is poor.
A coffee machine drain valve including a valve body, exhaust hole piece and a base is designed. The ball is used to press upwards and block the inlet end under the action of air pressure to form a confined space to prevent gas leakage and fall naturally when the air pressure is low for rapid drainage.
It effectively solves the problem of dirt blocking the channels due to long-term use, improves service life, and improves the regulation reaction performance through lightweight material spheres.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coffee machines, and in particular relates to an exhaust valve for coffee machines. Background Art
[0002] At present, the drain valves used in coffee machines on the market are mainly mechanical and electric. Although the electric type is easy to use, it is expensive and the life of the drain valve is affected by the quality of electronic components. The mechanical type is more complicated to operate, but the actual operation is complicated, the adjustment performance is poor, and the corrosion is serious. Therefore, there are disadvantages such as long-term use causing dirt to block the channel and a short service life. Utility Model Content
[0003] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.
[0004] To this end, the technical solution adopted by the utility model is: an exhaust valve for a coffee machine, including a valve body, a venting hole member is arranged on the upper part of the valve body, and a base is arranged on the lower part, a first channel on the valve body is connected with a second channel on the venting hole member, the second channel on the valve body is connected with a third channel on the base, the third channel on the base is connected with the inside of the coffee machine, the second channel on the venting hole member is connected with a copper joint, a ball is arranged in the base, and when the ball moves upward under the action of air pressure to support the valve body, the ball can block and close the first channel on the valve body.
[0005] A gasket is arranged between the valve body and the base.
[0006] The exhaust hole member is connected to the valve body by bolts.
[0007] Compared with the prior art, the utility model has the following beneficial effects: when the air pressure inside the coffee machine is relatively low, the sphere naturally falls due to gravity. The gas enters the third channel of the base through the air inlet end of the base, and communicates with the outside world through the valve body and the copper joint so that the pressure inside the valve body of the coffee machine is always equal to the pressure outside, and it is convenient for the coffee machine to drain water quickly when draining. When the air pressure inside the coffee machine is high, the sphere is pushed upward due to the air pressure, blocking the air inlet end of the first channel, forming a closed space to prevent gas leakage. This device effectively solves the shortcomings of the market that the channel is blocked by dirt due to long-term use and the service life is short. The sphere of the utility model is made of lightweight material, so that the adjustment reaction performance is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0011] On the contrary, the present application covers any alternatives, modifications, equivalent methods and solutions made to the essence and scope of the present application defined by the claims. Further, in order to enable the public to have a better understanding of the present application, some specific details are described in detail in the following detailed description of the present application. Those skilled in the art can fully understand the present application without the description of these details.
[0012] See Figures 1 to 2 , an emptying valve for a coffee machine, comprising a valve body 1, an exhaust hole member 2 is arranged on the upper part of the valve body 1, a base 3 is arranged on the lower part, a first channel on the valve body 1 is communicated with a second channel on the exhaust hole member 2, a second channel on the valve body 1 is communicated with a third channel on the base 3, the third channel on the base 3 is communicated with the inside of the coffee machine, a copper joint 4 is communicated with the second channel on the exhaust hole member 2, a sphere 5 is arranged in the base 3, when the sphere 5 moves upward under the action of air pressure and abuts against the valve body 1, the sphere 5 can block and seal the first channel on the valve body 1.
[0013] A gasket is arranged between the valve body 1 and the base 3.
[0014] The exhaust hole member 2 and the valve body 1 are connected by bolts.
[0015] When the air pressure inside the coffee machine is relatively small, the sphere naturally falls due to gravity. The gas enters the third channel of the base through the air inlet end of the base, and is communicated with the outside through the valve body and the copper joint, so that the inside of the coffee machine valve body is always equal to the external pressure, and at the same time, it is convenient for the coffee machine to drain water quickly when draining.
[0016] When the air pressure inside the coffee machine is high, the sphere abuts upward due to the air pressure and blocks the air inlet end of the first channel, forming a sealed space to prevent gas leakage.
[0017] This device effectively solves the disadvantages of dirt clogging the channel and short service life caused by long-term use on the market. The sphere of the present utility model adopts a light material, so that the adjustment reaction performance is strong.
