Description

Technical Field

[0001] The utility model relates to the technical field of fluid pumps, in particular to a liquid leakage-proof peristaltic pump for a cooking machine. Background Art

[0002] A cooking machine is a kitchen appliance that can automatically cook. At present, it has been widely used in the catering industry and home kitchens. The most basic cooking machine has a relatively simple function and structure. It generally includes a heating mechanism for heating food materials and a stir-frying mechanism for stirring food materials. When using it, the user needs to manually put the ingredients or related seasonings into the pot of the cooking machine, and then the heating mechanism and the stir-frying mechanism automatically process the ingredients into dishes. Since the addition of seasonings still requires manual intervention, the automation level of this type of cooking machine needs to be improved. With the continuous advancement of technology, people have invented cooking machines that can automatically add related materials. By adding a seasoning mechanism, this type of cooking machine can add related seasoning items to the pot at a regular and quantitative time, thereby greatly improving the full automation level of the cooking machine.

[0003] At present, the function of automatically adding seasonings in cooking machines is mostly realized by peristaltic pumps. The working principle of the peristaltic pump is as follows: the peristaltic pump motor provides power to drive the pump head to operate, and the rollers in the pump head work by alternately squeezing and releasing the elastic hose to generate pumping efficiency; the squeezed fluid in the elastic hose generates flow output, and when the pressure disappears, the hose relies on its own elasticity to restore its original state, the volume increases, and a vacuum is generated, thereby sucking in the fluid. Therefore, the amount of seasoning added can be precisely controlled by setting the number of revolutions or rotation time of the motor. However, after a period of use, the existing peristaltic pump for cooking machines has a pipeline (elastic hose) that is prone to rupture due to wear (generally, the wear time for a pipeline with a wall thickness of 3mm is about half a year). Once the pipeline is worn, the fluid in the pipeline (such as soy sauce and other seasoning media) will flow out. Due to the leakage of seasoning, the amount of seasoning added to the pot will definitely be less than the standard value, which will eventually cause the dish to taste poor and reduce quality; at the same time, the leaked seasoning material may flow and accumulate freely inside the pump body, thereby corroding the relevant parts of the peristaltic pump, and it is difficult for users to find it. Users may need to wait for a long time before discovering the pipeline leakage, such as waiting for the material to stink and the smell to drift out before being discovered by users. In view of this, the present application aims to provide a peristaltic pump for a cooking machine, which can prevent the material from flowing freely after leakage and corroding the corresponding parts, and is convenient for users to observe pipeline leakage. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art and provide a peristaltic pump for a cooking machine to prevent liquid leakage, which can prevent the material from flowing freely and corroding after the pipeline is damaged, and the user can observe the pipeline leakage at the first time for timely maintenance and treatment.

[0005] The technical solution of the utility model is: a peristaltic pump for preventing liquid leakage for a cooking machine, comprising a pump body and a rotor, an inner cavity is arranged inside the pump body, the rotor is arranged in the inner cavity, a material inlet and a material outlet are arranged on the pump body, and a guide structure is also arranged on the pump body, the guide structure is used to guide the fluid to flow to the bottom of the pump body, a waste liquid outlet is arranged below the guide structure, a waste liquid pipe joint is installed at the waste liquid outlet, the waste liquid pipe joint is connected to one end of a discharge pipe, and the other end of the discharge pipe is connected to a collection container.

[0006] Furthermore, the pump body includes a base and a pump casing, and two ends of the rotor are movably connected to the base and the pump casing respectively. The rotor is connected to the motor and rotates when driven by the motor.

[0007] Furthermore, the base is in the shape of a flat plate, and the pump shell is in the shape of a hemispherical shell.

[0008] Furthermore, the rotation axis of the rotor is perpendicular to the base.

[0009] Furthermore, a guide structure is provided on the base, and the guide structure is a guide groove, and the guide groove is provided on the inner surface of the base, and the direction of the guide groove is vertically downward. The inner diameter of the guide groove or the waste liquid outlet is adapted to the inner diameter of the feed pipeline. If the inner diameter of the guide groove or the waste liquid outlet is too small, the waste liquid will flow out slowly and easily overflow outside the pump casing, and will not be able to prevent liquid leakage; if the guide groove or the waste liquid outlet is too large, it will affect the size of the peristaltic pump material inlet and outlet positions (limited by the volume of the peristaltic pump body), thereby affecting the conveying function of the peristaltic pump itself. The guide structure may also include a protrusion provided on the base, that is, any structure that can centrally guide the leaked fluid to flow to the waste liquid outlet below the pump body can be used as a guide structure.

[0010] Furthermore, a fixing ring is arranged in the middle of the base, and the rotor and the fixing ring are arranged coaxially.

[0011] Furthermore, the guide groove passes through the fixing ring, so when the fluid material leaks into the fixing ring, the leaked material can also flow downward through the guide groove and will not accumulate in the fixing ring.

[0012] Furthermore, the drain pipe or the collecting container is made of a transparent material, so that the user can observe whether there is material in the drain pipe or the collecting container.

[0013] Furthermore, the pump housing is made of transparent material, which is convenient for observing the inner cavity of the pump body. The pump housing and the base are detachably connected.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the peristaltic pump in the utility model is provided with a guide groove, so that when a leakage occurs in the seasoning delivery pipeline, the outflowing liquid can be concentrated and guided to the collecting container under the pump body, thereby preventing the waste liquid from flowing to other positions of the cooking machine at will and polluting or corroding the relevant parts of the cooking machine. In addition, it is also convenient to check whether there is liquid in the collecting container, thereby determining whether the peristaltic pump tube is damaged, so as to replace the damaged peristaltic pump tube in time.
