Description

Technical Field

[0001] This utility model specifically relates to an improved structure for a filter module. Background Technology

[0002] An improved structure of existing filter modules, such as Chinese Utility Model Patent CN203885248U, entitled "An Easy-to-Clean Juicer," authorized on October 22, 2014, includes a base with a motor, a juice collection chamber connected to one side of the base, a crushing and extruding section placed within the juice collection chamber, and an end cap for fixing the crushing and extruding section. The crushing and extruding section includes a screw and a crushing cylinder that cooperates with the screw. The screw is arranged laterally. The juicer also includes a filter section located at the front end of the crushing cylinder. The filter section includes multiple filter rings with pulp and juice filtration gaps between them. By configuring the filter section to consist of multiple filter rings with pulp and juice filtration gaps between them, the filter section adopts a gap structure, making it less prone to clogging by material residue and easier to clean. At the same time, the juice can flow out smoothly and promptly from the gaps, accelerating the juice extraction efficiency.

[0003] However, the juicer with the above structure still has the following shortcomings: (1) The above filter section is composed of multiple filter rings and multiple filter rings are sleeved on the positioning column through the mounting hole, thereby realizing the installation of multiple filter rings on the crushing section. However, due to the manufacturing precision of the positioning column and the mounting hole, there is a large gap between the positioning column and the mounting hole. When in use, the filter rings are easily subjected to the horizontal force of the high-speed rotating screw, causing different filter rings to undergo different degrees of horizontal displacement, thereby shortening the pulp and juice filtration gap and affecting the filtration effect. Furthermore, the filter rings and the positioning column are subjected to the horizontal force of the screw for a long time, and the filter rings and the positioning column are easily deformed or even damaged, affecting the service life of both. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology and provide an improved filter module structure that ensures filtration effectiveness and extends service life.

[0005] The purpose of this utility model is achieved as follows:

[0006] An improved filter module structure includes a first module and a second module. The second module is movably connected to the lower part of the first module, and the inner circumferences of the first and second modules form a pressing space. A first filter gap is provided between the second and first modules. The improved structure features a mounting recess at the lower part of the first module and a mounting protrusion on the second module corresponding to the mounting recess. The mounting protrusion is inserted into the mounting recess, and a connector passes through the mounting protrusion of the second module and the mounting recess of the first module from bottom to top, connecting the second and first modules together. This improved filter module structure achieves high precision through the cooperation of the mounting protrusion and the mounting recess, resulting in a smaller horizontal gap. This effectively prevents large horizontal displacement of the second module on the first module under stress, ensuring the filtration accuracy of the first filter gap and the filtration effect of the filter module. Furthermore, the radial cooperation of the mounting protrusion and the mounting recess effectively distributes the radial force on the second module and the connector, thus improving the service life of the second module and the connector.

[0007] The objective of this utility model can also be achieved by the following technical measures:

[0008] Furthermore, the lower part of the second module is also provided with a concave cavity. The upper end of the connector passes upward through the concave cavity, the mounting protrusion, and the mounting recess. The lower end of the connector is located inside the concave cavity, and there is a movable gap between the lower end of the connector and the inner top surface of the concave cavity, so that the second module and the first module are connected in the movable manner. This allows the second module to move downward along the movable gap, enabling the second module to be opened in the first module, facilitating the cleaning of the first filter gap between the first module and the second module. In addition, the concave cavity serves to hide the connector.

[0009] Specifically, the height of the mounting recess is less than the height of the mounting protrusion, and the upper surface of the mounting protrusion abuts against the inner top surface of the mounting recess; so as to form a first filter gap between the first module and the second module, which is relatively simple and convenient to implement.

[0010] Specifically, the mounting protrusion is a mounting post that is narrower at the top and wider at the bottom, and the mounting recess is a mounting groove that is narrower at the top and wider at the bottom. The mounting post that is narrower at the top and wider at the bottom cooperates with the mounting groove that is narrower at the top and wider at the bottom, which not only facilitates the insertion of the mounting post into the mounting groove, but also improves the connection stability after the mounting post is inserted into the mounting groove and enhances the fitting accuracy between the two.

[0011] Furthermore, a positioning protrusion is provided on the outer side of the mounting protrusion, and a positioning groove is provided on the inner side of the mounting recess, with the positioning protrusion extending into the positioning groove; the cooperation between the positioning protrusion and the positioning groove provides a good installation guide for the mounting protrusion in the mounting recess, facilitating the installation of the mounting protrusion in the mounting recess.

[0012] Specifically, the first module is a hollow pressing cylinder, and the second module is a hollow ring assembly. The inner circumference of the hollow ring assembly extends upward with a first upper protrusion. The lower part of the inner circumference of the pressing cylinder is provided with a first upper concave portion corresponding to the position of the first upper protrusion. The first upper protrusion extends into the first upper concave portion, and the first filter gap exists between the first upper protrusion and the first upper concave portion. The mounting protrusion is located outside the first upper protrusion. The first filter gap is formed by the first upper protrusion and the first upper concave portion, which is relatively simple and convenient to implement.

[0013] Specifically, the first filter gap includes a first radial section, a first axial section, and a first coiled section that slows down the flow of juice. The two ends of the first coiled section are connected to the first axial section and the first radial section, respectively. The first radial section facilitates the entry of juice in the pressing space into the first filter gap. The first coiled section slows down the juice discharge speed, which helps the juicing material to be fully ground and discharged in the pressing space, improving the grinding effect and juice yield of the juicing material. The first axial section facilitates the faster discharge of juice from the first filter gap after passing through the first coiled section.

[0014] Specifically, the upper surface of the first convex portion and the inner top surface of the first concave portion form the first radial segment, the outer side surface of the first convex portion and the inner side surface of the first concave portion form the first axial segment, a first transition portion is provided between the upper surface of the first convex portion and the outer side surface of the first convex portion, a second transition portion is provided between the inner top surface of the first concave portion and the inner side surface of the first concave portion, and the first transition portion and the second transition portion form the first coiled segment; the first radial segment, the first coiled segment and the first axial segment are all surrounded by the first convex portion and the first concave portion, and the formation of the first radial segment, the first coiled segment and the first axial segment is relatively easy.

[0015] Specifically, the upper surface of the hollow ring assembly located outside the first upper protrusion is set as an inclined surface. The inclined surface gradually slopes downward from the outside of the first upper protrusion towards the outer periphery of the hollow ring assembly. The mounting protrusion is set on the inclined surface. The inclined surface plays a good guiding role for the juice discharged from the first filter gap, which is conducive to the smooth discharge of the juice from the filter module.

[0016] Specifically, the hollow ring assembly includes multiple stacked hollow rings, with juice outlet gaps between adjacent hollow rings, and the first upper protrusion extending upward from the inner circumference of the uppermost hollow ring; it is relatively simple and convenient to implement, and the multiple juice outlet gaps can effectively improve the juice output of the hollow ring assembly.

[0017] The beneficial effects of this utility model are as follows:

[0018] This filter module features an improved structure. Through the cooperation of the mounting protrusion and mounting recess, the fit between the two is highly precise, meaning that the horizontal gap between them is small. This effectively prevents the second module from undergoing large horizontal displacement on the first module when under stress, ensuring the filtration accuracy of the first filter gap and guaranteeing the filtration effect of the filter module. Furthermore, the radial cooperation between the mounting protrusion and mounting recess also effectively distributes the radial force on the second module and the connector, which helps to extend the service life of the second module and the connector.

[0019] The cooperation between the positioning protrusion and the positioning groove provides a good installation guide for the installation of the mounting protrusion in the mounting groove, making it convenient for the mounting protrusion to be installed in the mounting groove.

[0020] The first radial section facilitates the entry of juice from the pressing space into the first filter gap. The first coiled section slows down the juice discharge speed, which helps the juicing material to be fully ground and discharged in the pressing space, improving the grinding effect and juice yield. The first axial section facilitates the faster discharge of juice from the first filter gap after passing through the first coiled section. Attached Figure Description
