Description

Technical Field

[0001] This application relates to the field of juice extraction technology, and more specifically, to a fruit and vegetable juice extraction device. Background Technology

[0002] In the prior art, for example, a fruit and vegetable juice extraction device disclosed in CN222603670U includes a tank, a fixed frame installed inside the tank, and a groove opened inside the fixed frame. A limiting rod is installed on the front of the groove. A first mounting frame is installed inside the fixed frame, and a second mounting frame is provided below the first mounting frame. Filter screens are installed inside both the second mounting frame and the first mounting frame, and a slider is installed outside the filter screen. A limiting block is connected to the outside of the slider, and a pressure plate is provided above the fixed frame.

[0003] This solution allows for easy movement of the filter screen by alternating operation of the first and second mounting frames, enabling continuous cleaning of the filter screen without stopping the machine. This prevents fruit, vegetable, and meat scraps from getting stuck in the filter screen holes and affecting the efficiency of fruit and vegetable juice delivery.

[0004] Although this solution allows the two filters to be pulled out and cleaned alternately through the first and second mounting frames, the two filters cannot be removed from the tank due to the cooperation of the limiting block and the limiting rod. As a result, dirt will splash onto the outside of the tank during cleaning, affecting the cleanliness and hygiene of the entire juice extraction device, and increasing the labor intensity of the workers. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a fruit and vegetable juice extraction device, aiming to improve upon the existing fruit and vegetable juice extraction device, which, although capable of continuous, alternating cleaning of the filter screen, suffers from the problem that the filter screen cannot detach from the tank, thus affecting the cleanliness and hygiene of the tank and increasing the labor intensity of workers.

[0006] This application discloses a fruit and vegetable juice extraction device, including an extraction tank. A top cover is coaxially mounted on the top of the extraction tank, and a drive assembly is mounted on the top cover. The drive assembly includes a pressure plate, and a juicing blade is coaxially fixed to the bottom of the pressure plate. The pressure plate rotates and moves up and down within the extraction tank. A filter assembly is sealed and inserted into the extraction tank. The filter assembly includes an upper filter element and a lower filter element that are identical in structure and size and are symmetrically arranged vertically. A leak-proof assembly is mounted on the side wall of the extraction tank. The leak-proof assembly elastically seals against the filter assembly, and the leak-proof assembly and the side wall of the extraction tank are adapted to form a sealed state.

[0007] According to an embodiment of this application, a fruit and vegetable juice extraction device has the following advantages: by utilizing the elastic contact between the leak-proof component and the filter component, when the upper or lower filter component is pulled out for cleaning, the leak-proof component can seal against the lower or upper filter component, ensuring the sealing of the extraction tank. In this way, the filter screen can be cleaned without stopping the machine, and the cleanliness of the side wall of the extraction tank will not decrease due to the cleaning of the filter screen on the extraction tank.

[0010] In some specific embodiments of this application, the upper filter element includes a filter screen, an extension plate, a pull ring, and two limiting strips. The filter screen is circular, the extension plate is fixed to one side of the filter screen, the pull ring is fixed to the outer edge of the extension plate and is axially protruding, and the two limiting strips are symmetrically fixed to both sides of the pull ring.

[0011] In some specific embodiments of this application, the filter screen and the inner wall of the extraction tank are adapted to each other.

[0012] In some specific embodiments of this application, the two limiting strips on the same side of the upper and lower filter elements are both located on the top side of the spacer strip.

[0013] In some specific embodiments of this application, the leak-proof component includes a positioning strip fixed to the outer wall of the extraction tank. The positioning strip is arc-shaped, and a blocking plate is elastically connected to the bottom side of the positioning strip. The blocking plate is arc-shaped and has a sealing sliding fit with the outer wall of the extraction tank.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] like Figures 1-4 As shown, a fruit and vegetable juice extraction device according to an embodiment of this application includes an extraction tank 1. A top cover 11 is coaxially disposed at the top of the extraction tank 1. A driving assembly 2 is disposed on the top cover 11. The driving assembly 2 includes a pressure plate 23. A juicing blade 25 is coaxially fixed to the bottom end of the pressure plate 23. The pressure plate 23 rotates and moves up and down within the extraction tank 1. Specifically, as shown... Figure 1 and Figure 2As shown, the drive assembly 2 also includes a motor 21 coaxially mounted on the top cover 11. The output shaft of the motor 21 extends into the top cover 11 and is connected to a passive telescopic member 24. The passive telescopic member 24 and the pressure plate 23 are coaxially fixed together. At least two active telescopic members 22 are also provided on the top cover 11. The telescopic ends of the two active telescopic members 22 extend into the top cover 11 and are slidably connected to the pressure plate 23. An annular groove 26 is coaxially provided on the pressure plate 23. The telescopic ends of the active telescopic members 22 are axially limited and inserted into the annular groove 26, and the two are slidably connected.

[0020] It can be understood that by extending or shortening the active telescopic component 22, the pressure plate 23 and the juicing blade 25 thereon will move up and down synchronously inside the extraction tank 1. During this process, the passive telescopic component 24 will also move up and down synchronously. It should be noted that the passive telescopic component 24 can only move axially. It can also be understood that the motor 21 and the passive telescopic component 24 are connected by a transmission. When the motor 21 starts, it will drive the passive telescopic component 24 to rotate, which in turn will drive the pressure plate 23 and the juicing blade 25 thereon to rotate. The above actions will realize the actions of chopping, squeezing and juicing fruits and vegetables.

[0021] It should be noted that an arc-shaped opening is provided on the side wall of the extraction tank 1, and the filter assembly 3 is sealed and slidably inserted into the arc-shaped opening. Two spacers 12 are symmetrically fixed on both sides of the arc-shaped opening, and the two spacers 12 are tangent to the side wall of the extraction tank 1.

[0022] It should be further noted that the extraction tank 1 is sealed with a filter assembly 3. The filter assembly 3 includes an upper filter element 31 and a lower filter element 32 with identical structure and size. The upper filter element 31 and the lower filter element 32 are arranged symmetrically in the vertical direction.

[0023] In a specific embodiment of this application, the upper filter element 31 is used as an example for description. The upper filter element 31 includes a filter screen 311, an extension plate 312, a pull ring 313, and two limiting strips 314. The filter screen 311 is circular. The extension plate 312 is fixed to one side of the filter screen 311. The pull ring 313 is fixed to the outer edge of the extension plate 312 and is axially protruding. The two limiting strips 314 are symmetrically fixed to both sides of the pull ring 313.

[0024] The filter screen 311 is compatible with the inner wall of the extraction tank 1.

[0025] It should be noted that when the upper filter element 31 is fully inserted into the extraction tank 1, the filter screen 311 is completely inside the extraction tank 1, and the extension plate 312 is outside the extraction tank 1. At this time, the extension plate 312 and the filter screen 311 form a sealed state with the extraction tank 1.

[0026] It is understandable that by symmetrically arranging the upper filter element 31 and the lower filter element 32, the pull rings 313 on both will face the upper and lower sides respectively, making it convenient for users to pull out the corresponding upper filter element 31 or lower filter element 32.

[0027] In a specific embodiment of this application, the two limiting strips 314 on the same side of the upper filter element 31 and the lower filter element 32 are both located on the top side of the spacer 12. It should be noted that the upper filter element 31 and the lower filter element 32 are sealed and slidably fitted together.

[0028] In a specific embodiment of this application, a leak-proof component 4 is provided on the side wall of the extraction tank 1. The leak-proof component 4 is elastically sealed against the filter component 3, and the leak-proof component 4 and the side wall of the extraction tank 1 are adapted to form a sealed state.

[0029] The leak-proof component 4 includes a positioning strip 41 fixed to the outer wall of the extraction tank 1. The positioning strip 41 is arc-shaped, and a blocking plate 42 is elastically connected to the bottom side of the positioning strip 41. The blocking plate 42 is arc-shaped and has a sealing sliding fit with the outer wall of the extraction tank 1.

[0030] In some specific embodiments of this application, a guide rod 43 is fixedly connected to the positioning strip 41, and a blocking plate 42 is slidably sleeved on the guide rod 43. An elastic member 44 is sleeved on the guide rod 43, and the two ends of the elastic member 44 abut against the positioning strip 41 and the blocking plate 42 respectively.

[0031] Therefore, it can be understood that during normal use, the blocking plate 42 is sealed to the extension plate 312 of the upper filter element 31 through the elastic element 44. When the upper filter element 31 is pulled out, the blocking plate 42 elastically abuts against the extension plate 312 of the lower filter element 32, and the outer wall of the extraction tank 1 is sealed at this time, preventing leakage of the contents of the extraction tank 1 due to the gap formed after the upper filter element 31 is pulled out. It can also be understood that when the lower filter element 32 is pulled out, the upper filter element 31 will be displaced downward by the elastic pressure of the blocking plate 42, and the two limiting strips 314 on it will abut against the partition strip 12 on the side wall of the extraction tank 1. At this time, the displacement of the blocking plate 42 and the upper filter element 31 also makes the extraction tank 1 sealed. It can also be understood that when installing the lower filter element 32, the upper filter element 31 is lifted upward and then the lower filter element 32 is inserted into the extraction tank 1.

[0032] It should be noted that the active telescopic component 22 in this application can be an electric push rod, and the elastic component 44 can be a spring. This application does not impose any specific restrictions, as long as it achieves the effect described in this application.

[0033] This design allows the upper filter element 31 and the lower filter element 32 to be pulled out of the extraction tank 1 alternately and cleaned independently, avoiding contamination of the side wall of the extraction tank 1 and reducing the labor intensity of the user. At the same time, the elastic sealing setting of the blocking plate 42 can maintain the sealing of the side wall of the extraction tank 1 at all times, preventing leakage of the extraction tank 1 after the upper filter element 31 or the lower filter element 32 is pulled out.

[0034] It should be noted that the specific models and specifications of the motor 21, active telescopic component 22, juicing blade 25, filter screen 311 and elastic component 44 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
