Description

Technical Field

[0001] This invention relates to the field of juicer technology, and more particularly to a fresh-squeezed orange juicer. Background Technology

[0002] Existing juicers generally use screw-type or knife-type pressing methods for juicing. Both methods require peeling, cutting, and washing the fruit before juicing. During the peeling and cutting process, the fruit pulp is easily contaminated, and the fruit is prone to oxidation, which cannot guarantee the hygiene, taste, and nutrition of the juice. Furthermore, there is a lack of orange juicers on the market that can juice whole oranges. This paper proposes an orange juicer that can guarantee hygiene, taste, and nutrition while juicing whole oranges. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fresh-squeezed orange juice machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fresh-squeezed orange juicer includes a base on which a drive unit, a juicing unit, and a retractable pressing device are mounted. The base has a sleeve for mounting the pressing device, which is retractably mounted inside the sleeve, with one end adapted to and connected to the juicing unit and the other end adapted to and connected to the drive unit. The juicing unit includes a juicing cover and a juicing chamber, with the juicing cover rotatably mounted at the front end of the juicing chamber.

[0006] Furthermore, the pressing device includes a pressing head, a pressing head connecting rod, a driving rod, and a driving part connecting block. One end of the pressing head connecting rod is adapted and installed with the pressing head. The front end of the driving rod is fitted inside the pressing head connecting rod, and the rear end of the driving rod is adapted and connected with the driving part connecting block.

[0007] Furthermore, the pressing head connecting rod is provided with a first cavity and a second cavity, and the outer circumferential wall of the pressing head connecting rod is provided with an external thread; the driving rod is adapted to be movably installed in the first cavity, and the driving part connecting block is adapted to be movably installed in the second cavity.

[0008] Furthermore, the sleeve is hollow, and the inner wall of the sleeve is provided with an internal thread that matches the external thread.

[0009] Furthermore, the pressing head is provided with a third cavity for installing the pressing head connecting rod, the front end of the pressing head is provided with a pointed part, and the outer wall of the pressing head is provided with a number of juicing ribs and a number of juice outlet holes.

[0010] Furthermore, a positioning block is provided below the juicing chamber, a positioning ring is provided on the positioning block, and a limiting block is provided above the juicing chamber.

[0011] Furthermore, the juicing cap includes a first cap body and a second cap body, which are adapted to be installed and connected, and a positioning buckle adapted to the positioning ring is provided between the first cap body and the second cap body; the juicing cap is rotatably installed on the juicing chamber through the cooperation of the positioning ring and the positioning buckle; a limiting groove adapted to the limiting block is provided on the upper part of the first cap body and the lower part of the second cap body.

[0012] Furthermore, the juicing cap is provided with several limiting strips.

[0013] Furthermore, a material discharge port is provided above the juicing chamber, and a juice outlet is provided at the bottom of the juicing chamber.

[0014] This invention has the following beneficial effects: It proposes an orange juicer that can juice whole oranges while ensuring hygiene and taste. Through the linkage between the motor and the pressing device, namely the linkage between the pressing head, the pressing head connecting rod, the drive rod and the drive unit connecting block, the telescopic pressing rod is slowly pushed forward at a uniform speed to press the orange. The orange does not need to be cut into pieces, which avoids the contamination of the pulp during the cutting process. It also reduces the chance of the pulp coming into contact with air after being cut into pieces, thus avoiding oxidation of the pulp and affecting its taste and nutrition.

[0019] The figure includes the following reference numerals: base 1, sleeve 11, internal thread 12, juicing part 3, juicing chamber 31, positioning block 32, positioning ring 33, limiting block 34, juicing cover 35, positioning buckle 351, first cover 36, second cover 37, limiting groove 38, limiting strip 39, pressing device 4, drive unit connecting block 41, pressing head 43, third chamber 431, tip 432, juicing rib 433, juice outlet 434, pressing head connecting rod 44, first chamber 441, external thread 443, and drive rod 45. Detailed Implementation

[0020] like Figure 1 , Figure 2 As shown, a fresh orange juicer includes a base 1, on which are mounted a drive unit (not shown), a juicing unit 3, a retractable pressing device 4, and a control panel (not shown). The drive unit and control panel are electrically connected to a power source. Specifically, the juicing unit 3 is mounted on the base 1 in an integral molding manner for ease of production and installation. Alternatively, it could be glued or welded, representing a direct substitution of equivalent technologies, as those skilled in the art should understand. The drive unit is located on one side of the base 1. One end of the pressing device 4 passes through the juicing unit 3 and is installed within it, while the other end is mounted to the drive unit. The drive unit, in conjunction with the pressing device 4, performs a retractable movement within the juicing unit 3 to press the fruit and obtain juice.

[0021] Furthermore, such as Figure 3 , Figure 4 As shown, the base 1 is provided with a sleeve 11 for installing the pressing device 4. The sleeve 11 is hollow and the inner wall of the sleeve 11 is provided with an internal thread 12. The internal thread 12 covers the entire inner wall of the sleeve 11, which facilitates the pressing device 4 to move back and forth in the juicing section 3 through the internal thread 12.

[0022] Furthermore, the pressing device 4 includes a pressing head 43, a pressing head connecting rod 44, a driving rod 45, and a driving part connecting block 41 connected in sequence.

[0023] Specifically, such as Figures 2-4 As shown, the pressing head 43 has a third cavity 431 for mounting the pressing head connecting rod 44. The third cavity 431 is located at the center of the pressing head 43, and the front end of the pressing head connecting rod 44 is adapted to be installed in the third cavity 431. When the pressing head connecting rod 44 rotates, the pressing head 43 rotates in the same direction. Furthermore, the front end of the pressing head 43 has a tip 432, which protrudes forward in a "drill" shape to position the fruit and pierce the peel. When juicing, the tip 432 pierces the fruit peel to fix it in place, making it less likely to shift during juicing and facilitating the pressing head 43 to enter the fruit for pressing. The outer wall of the pressing head 43 is provided with a number of juicing ribs 433 and a number of juice outlet holes 434. The juicing ribs 433 are designed in an "S" shape. When the pressing head 43 rotates to juic the fruit, the juicing ribs 433 can squeeze the pulp, so that the juice and pulp are quickly separated. Some of the juice can enter the juicing chamber 31 through the juice outlet holes 434, effectively improving the juicing efficiency and juice yield.

[0024] The pressing head connecting rod 44 is cylindrical, with its front end being oblong. The third cavity 431 follows this shape. An external thread 443 is provided on the outer circumference of the rear end of the pressing head connecting rod 44. This external thread 443 is adapted to the internal thread 12, and the pressing head connecting rod 44 moves back and forth within the sleeve 11 through the engagement of the external thread 443 and the internal thread 12. Furthermore, the pressing head connecting rod 44 contains a first cavity 441, and the driving rod 45 is movably fitted within this first cavity 441. Specifically, the driving rod 45 has an oblong cross-section, and the first cavity 441 follows and adapts to its shape. When the driving rod 45 rotates, it drives the pressing head connecting rod 44 to rotate as well. The tail end of the driving rod 45 has a semi-circular shape different from its front portion.

[0025] One end of the drive unit connecting block 41 is adapted to the end of the drive rod 45, and the other end is adapted to the drive unit. When the drive unit is started, it drives the drive unit connecting block 41 to rotate, and sequentially links the drive rod 45, the pressing head connecting rod 44, and the pressing head 43 to rotate synchronously.

[0026] Furthermore, the juicing part 3 includes a juicing cover 35 and a juicing chamber 31, wherein the juicing cover 35 is rotatably mounted on the front end of the juicing chamber 31. Specifically, a positioning block 32 is provided below the juicing chamber 31, a positioning ring 33 is provided on the positioning block 32, and a limiting block 34 is provided above the juicing chamber 31.

[0027] The juicing cover 35 includes a first cover body 36 and a second cover body 37, which are arranged side by side and integrally formed. A positioning buckle 351 adapted to the positioning ring 33 is provided between the first cover body 36 and the second cover body 37. The positioning ring 33 and the positioning buckle 351 are fixed by bolts or screws. The juicing cover 35 is rotatably mounted on the juicing chamber 31 through the cooperation of the positioning ring 33 and the positioning buckle 351. Furthermore, a limiting groove 38 adapted to the limiting block 34 is provided on the upper part of the first cover body 36 and the lower part of the second cover body 37. After the juicing cover 35 is rotated to the appropriate position, it is positioned and installed by the limiting block 34 and the limiting groove 38, so that it will not move or shift during operation.

[0028] The inner walls of the first cover 36 and the second cover 37 are provided with several limiting strips 39 to increase the friction between the juicing cover 35 and the orange, so as to prevent the fruit from rotating or shifting during the juicing process and affecting the juicing efficiency.

[0029] The juicing chamber 31 has a material discharge port 311 at the top and a juice outlet 312 at the bottom. A filter screen (not shown in the figure) may be provided on the juice outlet 312. The filter screen is used to filter the pulp that falls off during the juicing process, making the juice purer and taste better.

[0030] Furthermore, the inner diameter of the discharge port 311 is 70mm-90mm, preferably 90mm in this invention. This diameter is suitable for the size of large oranges on the market, making it convenient for users to put whole oranges into the port. The oranges do not need to be cut into pieces, and the oranges fall smoothly into the juicing chamber 31 for pressing. Compared with existing juicers or orange juice machines, the orange juice machine shown in this invention eliminates the need to cut oranges into pieces, saving the cutting process before juicing. It is more convenient, faster, and more hygienic, avoiding contamination of the pulp during the cutting process.

[0031] Working Principle: When the orange juicer is connected to the power supply and started, the first cover 36 is rotated upwards to seal and connect with the juicing chamber 31. A whole orange is placed into the discharge port 311. The drive unit drives the drive unit connecting block 41 to rotate at a constant speed, thereby linking the drive rod 45, the pressing head connecting rod 44, and the pressing head 43 to rotate synchronously. When the pressing head connecting rod 44 rotates, the external thread 443 and the internal thread 12 engage, causing the pressing head connecting rod 44 to be slowly pushed forward. In other words, the pressing head 43 is slowly pushed forward, squeezing the orange. The orange juice flows out from the juice outlet 312 after being filtered through the filter screen. When the pressing head connecting rod 44 is completely pushed out, the juicing is complete. At this time, the drive unit is operated to rotate in the opposite direction, causing the pressing head connecting rod 44 to move backwards at a constant speed, facilitating a second juicing. After juicing, the peel and pulp remain inside the upper juicing cover 35, specifically the first cover 36 or the second cover 37 installed with the juicing chamber 31. For ease of explanation, in this embodiment, the juicing cover 35 is the first cover 36. Since the pulp remains inside the first cover 36, its weight is greater than that of the lower second cover 37. Due to gravity, the first cover 36, with pulp remaining, swings downward around the positioning buckle 351, exchanging positions with the lower second cover 37. At this time, the second cover 37 is on top, corresponding to and sealingly installed with the juicing chamber 31, while the first cover 36 containing pulp is on the bottom. This allows the user to easily clean the pulp inside the first cover 36 while continuing to add oranges to the discharge port 311 for juicing, effectively improving juicing efficiency and facilitating user operation.
