Description

Technical Field

[0001] The utility model relates to the technical field of juicers, in particular to a filter screen and a juicer. Background Art

[0002] In daily life, people mainly use juicers to squeeze fruits and vegetables to extract juice to meet the intake of fruit and vegetable juice. Juicers generally include a squeezing mechanism and a filter. When squeezing fruits, the squeezed juice is separated from the pomace through the filter holes of the filter. However, when separating the pomace and juice, the general filter has a large hole depth and a small hole diameter, which causes the juice and pomace particles to be easily retained in the filter holes and difficult to remove. In addition, the filter holes have a large surface tension during cleaning. When flushing is not in place, the dirty water is sucked back into the filter holes under the action of surface tension, which affects the sanitary condition of the filter and is prone to breed bacteria. Utility Model Content

[0003] The main purpose of the utility model is to provide a filter screen, which is intended to prevent juice and dregs particles from being easily retained in the filter holes, making it easier to clean the filter screen.

[0004] To achieve the above-mentioned purpose, the filter proposed in the utility model is applied to a juicer, and the filter has a first side and a second side opposite to each other in the thickness direction, and the first side is used to place the squeezed material. The filter is provided with a plurality of filter holes, and the filter holes penetrate the first side and the second side along the thickness direction of the filter to allow juice on the first side to flow to the second side, and the hole depth of the filter holes ranges from 0.3 mm to 7 mm.

[0005] Optionally, the pore size of the filter pores ranges from 1 mm to 8 mm.

[0006] Optionally, the pore depth of the filter holes ranges from 3 mm to 5 mm.

[0007] Optionally, the filter screen is made of stainless steel.

[0008] Optionally, the filter is made of plastic.

[0009] Optionally, the diameter of the filter hole gradually increases in a direction from the first side surface toward the second side surface.

[0010] Optionally, in a direction from the first side surface toward the second side surface, the first side surface is arranged as a concave curved surface.

[0011] Optionally, the first side surface is arranged as a concave cone, and the cone angle of the concave cone is arranged at the center of the first side surface.

[0012] Optionally, the depth of the concave cone surface ranges from 10 mm to 18 mm.

[0013] Optionally, in the direction from the first side surface toward the second side surface, the second side surface is arranged as a convex conical surface adapted to the concave conical surface.

[0014] The utility model also provides a juicer, comprising the aforementioned filter screen.

[0015] Optionally, the juicer further comprises a base and a frame, wherein the end of the frame is mounted on the base, and the middle portion of the frame at least partially abuts against the second side surface of the filter screen to support the filter screen.

[0016] In the technical solution of the utility model, the depth of the filter holes is adjusted so that the residue and juice of the squeezed material are not easily retained in the filter holes. When the hole depth value is less than 0.3mm, due to the small hole depth, the thickness of the filter screen is also small, so that the structural strength of the filter screen is low, and the squeezed material placed on the first side of the filter screen may cause the filter screen to produce a large deformation during the squeezing process, resulting in the destruction of the structure of the filter screen; when the hole depth value of the filter hole is greater than 7mm, due to the large hole depth of the filter hole, the juice and residue of the squeezed material may remain in the filter hole, which is not convenient for cleaning the filter screen, and due to the small pore size of the filter hole, water is easily adsorbed in the filter hole under the action of surface tension during flushing, It will breed bacteria and cause the sanitation of the filter to be poor; therefore, the hole depth of the filter is set between 0.3mm and 7mm, so that the hole depth of the filter is within a more appropriate range. On the one hand, the filter has a certain structural strength during the squeezing of the squeezed material, and is not easy to be damaged by plastic deformation. On the other hand, the smaller hole depth makes it difficult for the residue and juice of the squeezed material to accumulate in the filter holes, which is convenient for the user to clean up the juice and residue remaining in the filter holes. At the same time, the smaller hole depth can effectively reduce the surface tension of water at the filter holes, so as to reduce the possibility of water being adsorbed at the filter holes under the action of surface tension during flushing, thereby improving the sanitation of the filter.

[0030] In daily life, people mainly use juicers to squeeze fruits and vegetables to extract juice to meet the intake of fruit and vegetable juice. Juicers generally include a squeezing mechanism and a filter. When squeezing fruits, the squeezed juice is separated from the pomace through the filter holes of the filter. However, when separating pomace and juice, the general filter has a large hole depth and a small hole diameter, which causes juice and pomace particles to be easily retained in the filter holes and difficult to remove. In addition, the filter holes have a large surface tension during cleaning. When flushing is not in place, dirty water is sucked back into the filter holes under the action of surface tension, which affects the sanitation of the filter and is easy to breed bacteria. To this end, the utility model proposes a filter, which is intended to prevent juice and pomace particles from being easily retained in the filter holes, making it easy to clean the filter.

[0031] Reference Figures 1 to 5In the technical solution of the utility model, the filter 100 is applied to a juicer. The filter 100 has a first side surface 110 and a second side surface 120 opposite to each other in the thickness direction. The first side surface 110 is used to place the squeezed material 900. The filter 100 is provided with a plurality of filter holes 130. The filter holes 130 penetrate the first side surface 110 and the second side surface 120 along the thickness direction of the filter 100 so that the juice on the first side surface 110 flows to the second side surface 120. The hole depth of the filter holes 130 ranges from 0.3 mm to 7 mm. The squeezed object 900 in this solution can be oranges, tangerines, watermelons, lychees, cucumbers, etc., and this application does not limit this. In order to facilitate understanding of this solution, the squeezed object 900 in this article is described by taking oranges as an example. Oranges are placed on the first side 110. During the process of squeezing the oranges by the juicer, the orange juice flows from the first side 110 to the second side 120 through the filter holes 130. In this process, orange juice and pomace particles are likely to remain in the filter holes 130 due to the large hole depth of the filter holes 130. If the orange A lot of juice and pomace particles remain in the filter pores 130. On the one hand, the orange juice and pomace particles accumulated in the filter pores 130 are prone to deterioration and breeding of bacteria, resulting in poor sanitary conditions of the filter 100 and affecting the quality of the subsequently squeezed orange juice. On the other hand, the filter pores 130 are deep, which makes it inconvenient to clean the orange juice and pomace particles remaining in the filter pores 130. In addition, water during flushing is easily adsorbed in the filter pores 130 under the action of surface tension, which is easy to breed bacteria, resulting in poor sanitary conditions of the filter 100. Therefore, the present invention adjusts the depth of the filter hole 130 so that the orange juice and pomace particles are not easily retained in the filter hole 130. A large amount of orange juice and pomace particles may remain in the filter hole 130, which makes it inconvenient to clean the filter 100. In addition, since the pore size of the filter hole 130 is small, water is easily adsorbed in the filter hole 130 under the action of surface tension during flushing, which will breed bacteria and cause the sanitation of the filter 100 to be poor. Therefore, the pore depth of the filter hole 130 is set between 0.3 mm and 7 mm, so that the pore depth of the filter hole 130 is within a relatively large range. Within a suitable range, on the one hand, the filter 100 has a certain structural strength during the squeezing of the oranges and is not easily damaged by plastic deformation; on the other hand, a smaller pore depth value makes it difficult for orange juice and pomace particles to accumulate in the filter holes 130, making it convenient for the user to clean up the orange juice remaining in the filter holes 130; meanwhile, a smaller pore depth value can effectively reduce the surface tension of water at the filter holes 130, thereby reducing the possibility of water being adsorbed at the filter holes 130 under the action of surface tension during flushing, thereby improving the sanitary condition of the filter 100.

[0032] Furthermore, in one embodiment, the hole depth of the filter hole 130 ranges from 3 mm to 5 mm. Thus, limiting the hole depth value to between 3 mm and 5 mm, on the one hand, makes the thickness value of the filter 100 within a suitable range, improves the structural strength of the filter 100 when the thickness is set to the lowest value, and makes the filter 100 less likely to be deformed and damaged during the process of squeezing oranges with a juicer; on the other hand, limiting the hole depth value of the filter hole 130 within a smaller range, further reduces the amount of orange juice remaining in the filter hole 130, and improves the convenience of cleaning the filter 100.

[0033] Optionally, in one embodiment, the aperture of the filter hole 130 ranges from 1 mm to 8 mm. Thus, when the aperture of the filter hole 130 is too small, the orange juice may not easily flow into the filter hole 130 and accumulate on the first side 110, making it inconvenient to collect the orange juice; when the aperture of the filter hole 130 is too large, pomace may flow into the filter hole 130, and the pomace may flow from the first side 110 to the second side 120 together with the orange juice, reducing the separation effect between the pomace and the orange juice, thereby reducing the quality of the orange juice. The pomace may also cause the filter hole 130 to be blocked, making it difficult for the orange juice to flow from the first side 110 to the second side 120 through the filter hole 130, and also It is inconvenient to clean the filter 100, and the pomace and orange juice that are blocked in the filter holes 130 for a long time will deteriorate, making the sanitation of the filter 100 poor, thereby reducing the quality of the orange juice; therefore, the aperture value of the filter holes 130 is set between 1 mm and 8 mm. On the one hand, it is easy for the orange juice to flow into the filter holes 130 and be separated from the pomace. On the other hand, it is not easy for the pomace to flow into the filter holes 130 and cause blockage, or flow from the first side 110 to the second side 120 together with the orange juice, thereby improving the separation effect between the pomace and the orange juice, thereby improving the quality of the orange juice.

[0034] Optionally, in another embodiment, there are many options for setting the aperture size of the filter hole 130. The aperture size of the filter hole 130 can also be set at 9 mm, as long as the filter hole 130 can achieve the separation function between pomace and orange juice.

[0035] Optionally, in one embodiment, the filter 100 is made of stainless steel. In this way, the filter 100 is made of stainless steel, so that the filter 100 has a high structural strength, and the filter 100 is not prone to excessive deformation and damage when it is subjected to the pressure of the juicer and the orange; because orange juice contains fruit acid, which is highly corrosive and will corrode the instrument and cause damage to the instrument, therefore, the filter 100 made of stainless steel with strong corrosion resistance is selected to reduce the risk of the fruit acid in the orange juice corroding and damaging the filter 100, effectively extending the service life of the filter 100.

[0036] Optionally, in another embodiment, there are many choices for the material of the filter 100. Aluminum can be selected to make the filter 100. Since aluminum has strong corrosion resistance, the possibility of corrosion damage to the filter 100 by the fruit acid in the orange juice can be reduced. Other materials can also be selected to manufacture the filter 100, as long as they are resistant to corrosion by fruit acid.

[0037] Optionally, in another embodiment, the material of the filter 100 is configured as plastic. In this way, a lighter plastic material is selected to make the filter 100 to reduce the weight of the filter 100, making the juicer as a whole lighter and more convenient for users to take and use. The production cost of the filter 100 made of plastic is low, which is easy to promote.

[0038] In the embodiment where the filter 100 is made of plastic, optionally, the diameter of the filter hole 130 gradually increases in the direction from the first side 110 toward the second side 120. That is, the filter hole 130 is arranged in a trumpet shape. On the one hand, it is used to guide the orange juice to flow to the filter hole 130 and accelerate the flow of oranges in the filter hole 130. The trumpet-shaped structure can also help the oranges flow more smoothly in the filter hole 130, reduce resistance loss, and facilitate the smooth flow of orange juice through the filter hole 130. On the other hand, it can reduce the amount of orange juice remaining in the filter hole 130, and improve the convenience of cleaning the filter 100.

[0039] The shape of the filter holes 130 can be set in many ways. For example, in other implementations, the pore diameters of the filter holes 130 in the depth direction are all set to the same size, as long as the oranges can flow through the filter holes 130.

[0040] Optionally, in one embodiment, the first side surface 110 is arranged as a concave curved surface in the direction from the first side surface 110 toward the second side surface 120. In this way, the first side surface 110 of the filter 100 is arranged as a concave curved surface, so that the orange placed on the first side surface 110 can roll to the bottom of the concave curved surface of the first side surface 110 under the action of gravity, so that the juicer can squeeze the orange.

[0041] In order to facilitate understanding of the squeezing work of the juicer on oranges in this solution, the process of squeezing oranges by the juicer is introduced here. In this application, whole oranges with peels are used for squeezing. Figure 4 and Figure 5The juicer includes a frame 400, a base 200, a rolling plate 500, a first driving device 600, a second driving device 700, and a juice storage box 800, wherein the rolling plate 500 and a filter screen 100 for placing oranges are arranged on the frame 400, the rolling plate 500 is arranged above the filter screen 100 at intervals, and a squeezing space is formed with the filter screen 100, the rolling plate 500 has a squeezing area for squeezing oranges, the filter screen 100 is provided with a filter hole 130, the juice storage box 800 is arranged below the filter screen 100, and is used to receive the orange juice flowing out of the filter hole 130, the first driving device 600 and the second driving device 700 are both It is arranged on the frame 400. When juicing, the first driving device 600 drives the rolling disc 500 to perform oscillating rolling, and the second driving device 700 drives the base 200 to move toward the rolling disc 500. At this time, the filter 100 follows the base 200 to move toward the rolling disc 500 to reduce the squeezing space so that the juice is squeezed out of the oranges between the filter 100 and the rolling disc 500. After the juicing is completed, the first driving device 600 stops driving the oscillating movement of the rolling disc 500, and the second driving device 700 drives the base 200 to drive the filter 100 to move in the direction away from the rolling disc 500, thereby completing a juicing operation. It is understandable that the base 200, driven by the second driving device 700, will only change the distance from the rolling disc 500 in the up and down directions, while the projection position of the squeezing area of ​​the rolling disc 500 on the filter 100 remains relatively unchanged. Therefore, when the rolling disc 500 is squeezing oranges, the oranges need to be positioned first so that the oranges are located within the projection of the squeezing area of ​​the rolling disc 500 on the filter 100, so that the rolling disc 500 can squeeze the oranges. Otherwise, if the oranges deviate from the squeezing area of ​​the rolling disc 500, the rolling disc 500 may not squeeze the oranges or cause one side of the orange to be squeezed and deviate from the squeezing area of ​​the rolling disc 500, thereby reducing the squeezing efficiency and quality of the oranges by the juicer. Therefore, the first side surface 110 of the filter 100 is set to be a concave surface, so that a complete orange can be automatically positioned under the action of gravity, and the orange can spontaneously roll from the first side surface 110 to the bottom of the concave surface of the first side surface 110. It is worth mentioning that the bottom of the concave surface corresponds to the squeezing area of ​​the rolling disc 500, and the bottom of the concave surface falls within the projection of the squeezing area of ​​the rolling disc 500 on the filter 100. Therefore, the orange can be accurately squeezed by the rolling disc 500 to extract juice, thereby improving the squeezing efficiency and quality of the juicer for the orange.

[0042] Furthermore, in one embodiment, the first side surface 110 is provided as a concave cone surface 111, and the cone angle of the concave cone surface 111 is provided at the center of the first side surface 110. In this way, the first side surface 110 is provided as a concave cone surface 111, and the cone angle of the concave cone surface 111 is provided at the center of the first side surface 110, so that the orange can roll to the center of the first side surface 110 under the action of gravity. It is worth mentioning that the projection of the squeezing area of ​​the rolling disc 500 on the filter screen 100 falls into the center of the first side surface 110, so that the orange can be automatically positioned and accurately squeezed by the rolling disc 500 to extract juice, which reduces the deviation of the orange from the squeezing area of ​​the rolling disc 500 and reduces the efficiency and quality of squeezing the orange by the juicer.

[0043] Optionally, in one embodiment, the depth of the concave cone surface 111 ranges from 10 mm to 18 mm. In this way, if the depth value of the concave cone 111 is set too small, the orange placed on the first side 110 may not be easy to spontaneously move on the concave cone 111, so that the positioning of the orange cannot be achieved, and the orange may deviate from the squeezing area setting of the rolling disc 500, so that the rolling disc 500 cannot squeeze the orange, thereby reducing the squeezing efficiency and quality of the orange by the juicer; if the depth value of the concave cone 111 is set too large, the periphery of the rolling disc 500 may directly squeeze the filter 100, thereby reducing the squeezing force on the orange, resulting in incomplete squeezing of the orange, reducing the squeezing efficiency and quality of the orange by the juicer, and may also cause the rolling disc 500 to directly squeeze the filter 100 and damage the filter 100. If the depth value of the concave cone 111 is set too large, it may also cause the rolling disc 500 to be unable to contact the orange, thereby reducing the squeezing quality of the orange by the juicer. Therefore, the depth of the concave cone 111 is set between 10 mm and 18 mm. On the one hand, the orange can roll to the center of the first side surface 110 spontaneously under the action of gravity, so as to achieve the positioning of the orange and facilitate the rolling disc 500 to squeeze the orange to extract juice; on the other hand, when the orange rolls to the center of the first side surface 110, there is still a large contact area with the rolling disc 500, so that the orange can absorb most of the force of the rolling disc 500, and the rolling disc 500 can cooperate with the filter 100 to fully squeeze the orange, thereby improving the squeezing quality of the orange by the juicer.

[0044] Optionally, in another implementation, there are many options for the depth value of the concave cone surface 111, and the depth value of the concave cone surface 111 can also be set at 19 mm, as long as the rolling disc 500 can achieve the squeezing work of the oranges.

[0045] Optionally, in one embodiment, in the direction from the first side surface 110 toward the second side surface 120, the second side surface 120 is provided as a convex conical surface 121 adapted to the concave conical surface 111. Thus, in the direction from the first side surface 110 toward the second side surface 120, the second side surface 120 is provided as a convex conical surface 121 adapted to the concave conical surface 111, so that the orange can roll to the cone angle of the concave conical surface 111, that is, the center of the first side surface 110, under the action of gravity.

[0046] The utility model further provides a juicer, which includes the aforementioned rolling plate 500, frame 400, base 200, first drive device 600, second drive device 700, juice storage box 800, and filter 100. The specific structure of the filter 100 refers to the above-mentioned embodiment. Since the juicer adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0047] The juice extractor further includes a frame 300, the ends of which are mounted on the base 200, and the middle of the frame 300 at least partially abuts against the second side surface 120 of the filter 100, so as to support the filter 100. In this way, the frame 300 is arranged below the filter 100, so that the frame 300 abuts against the second side surface 120 of the filter 100, and is used to share the pressure borne by the filter 100, so as to enhance the pressure bearing capacity of the filter 100, and reduce the possibility of structural damage of the filter 100 due to excessive pressure. At the same time, the frame 300 can also effectively limit the displacement of the filter 100 downward, reduce the displacement of the filter 100 downward under the pressure from the rolling plate 500, and reduce the risk of damage to the filter 100 due to plastic deformation.

[0048] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
