Description

Technical Field

[0001] This application relates to the field of water purifiers, and more particularly to a water purification machine for food safety production. Background Technology

[0002] Currently, in the process of processing beverages, the water quality is very important in order to improve the safety and quality of beverages. To improve the water quality of beverages, tap water generally needs to be purified, and the current tap water purification is mainly carried out by water purifiers.

[0003] Regarding the aforementioned technologies, there are still some shortcomings: Water purification devices can sterilize water and prevent microbial contamination. However, when these devices are applied to the production of beverages and food products, we have found that the filter cartridges inside the purification devices need to be replaced regularly during the water purification process. Currently, the replacement method involves disassembling the housing with screws and then replacing the filter cartridges. This process is cumbersome and affects the convenience of filter cartridge replacement. Utility Model Content

[0004] To facilitate filter replacement, this application provides a water purification machine for food safety production.

[0005] This application provides a water purification machine for food safety production, which adopts the following technical solution:

[0006] A water purification machine for food safety production includes a housing and a U-shaped frame. The U-shaped frame has a U-shaped cavity for installing a filter cartridge. The U-shaped frame is inserted through the side of the housing. Drive rods are slidably connected to both ends of the U-shaped frame. Worms are rotatably connected to the upper and lower sides of each drive rod. The drive rod has an external thread that engages with the worm gear. A limit block is integrally formed on the worm gear. The limit block has a locking position and an unlocking position. When the limit block is in the locking position, it is perpendicular to the drive rod and can contact the wall of the filter cartridge. When the limit block is in the unlocking position, it is parallel to the drive rod and misaligned with the filter cartridge.

[0007] Optionally, a parallel block is fixedly connected to the end of the drive rod, and a baffle plate is slidably connected to one end of the encapsulation housing near the parallel block. When the baffle plate is in close contact with the parallel block, the position of the limiting block is locked.

[0008] Optionally, the side of the shield facing away from the drive rod has a linear array of multiple anti-slip patterns.

[0009] Optionally, a limiting member is also connected inside the U-shaped cavity, and a limiting spring is connected between the limiting member and the U-shaped cavity. The ends of the limiting members that are close to each other can fit tightly together, and the limiting spring makes the limiting members always have a tendency to move towards the limiting member in the opposite direction.

[0010] Optionally, each of the limiting members has an arc-shaped groove at one end that is close to the other.

[0011] Optionally, a handle is rotatably connected to the end of the U-shaped frame, and a storage cavity for inserting the handle is provided at the end of the encapsulation housing.

[0012] Optionally, a magnetic component is fixedly bonded to the inner wall of the storage cavity, and the magnetic component can be magnetically connected to the storage cavity.

[0013] In summary, the beneficial technical effect of this application is that when the user places the filter cartridge into the U-shaped cavity, the filter cartridge will first push the limiting member, and the limiting member will initially limit the filter cartridge. Then the user pushes the drive rod to make the limiting block clamp the filter cartridge, thus realizing the installation of the filter cartridge.

[0014] When the user needs to remove the filter cartridge from the U-shaped frame, the U-shaped frame must first be pulled out of the packaging shell, and then the drive rod is pushed to rotate the limit block to be misaligned with the filter cartridge, thus enabling the filter bottle to be removed.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses a water purification machine for food safety production. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 A water purification machine for food safety production includes a housing 1 and a U-shaped frame 2. The U-shaped frame 2 has a U-shaped cavity 3 for mounting filter cartridges 16, and multiple filter cartridges 16 are arranged in an array within the U-shaped cavity 3. The U-shaped frame 2 slides along the side of the housing 1. The multiple filter cartridges located within the U-shaped frame 2 are connected by conduits, and a water inlet pipe communicating with the filter cartridges is located above the housing 1, connecting to the ends of the filter cartridges. A water outlet pipe and a drain pipe are also located below the housing 1 to treat impurities generated after filtration by the filter cartridges 16.

[0023] Reference Figure 2 , Figure 3 as well as Figure 4 A drive rod 4 is installed at both ends of the U-shaped frame 2, and the drive rod 4 can slide freely within the U-shaped frame 2. A worm gear 5 is connected to the upper and lower ends of the drive rod 4, and the worm gear 5 is set perpendicular to the drive rod 4. The drive rod 4 also has an external thread that can rotate with the worm gear 5. The two worm gears 5, one above the other, form a group and are used to fix the filter bottle located between the two worm gears 5. In this embodiment, a total of three filter bottles are arranged in the U-shaped frame 2, and the number of groups of worm gears 5 is the same as the number of filter bottles. A limiting block 6 is integrally formed on the solid part of the worm gear 5 located in the U-shaped cavity 3, which can contact the filter bottle and fix the position of the filter bottle. Depending on the position of the limiting block 6, the limiting block 6 has a locking position and an unlocking position.

[0024] When the user pushes the drive rod 4 outwards from the U-shaped frame 2, the two worm gears 5, threadedly connected to the drive rod 4, will rotate in different directions. The free ends of the two limit blocks 6 also rotate in opposite directions as the worm gears 5 rotate. When the limit blocks 6 rotate to a position parallel to the drive rod 4, they are in the unlocked position, and a gap exists between the limit blocks 6 and the filter bottle. The filter bottle can then move horizontally within the U-shaped cavity 3 without being obstructed by the limit blocks 6, allowing the user to slide the filter bottle out of the U-shaped cavity 3 for replacement.

[0025] If the user pushes the two drive rods 4 in the direction of pushing into the U-shaped frame 2, the position of the limiting block 6, which was originally parallel to the drive rod 4, will change. The free ends of the two limiting blocks 6 will move towards each other until the two limiting blocks 6 are in close contact with the sides of the filter bottle. At this time, the limiting blocks 6 are in the locking position, which reinforces the filter bottle located in the U-shaped cavity 3.

[0026] Reference Figure 2 , Figure 3 as well as Figure 4 Parallel blocks 7 are also provided at the ends of the two drive rods 4. The user can move both drive rods 4 simultaneously by pulling the parallel blocks 7. A baffle plate 8 is slidably connected to the end of the housing 1 of the parallel blocks 7 near the parallel blocks 7. When the baffle plate 8 falls freely under gravity, it can block the parallel blocks 7. At this time, the parallel blocks 7 are located between the baffle plate 8 and the U-shaped frame 2.

[0027] After the user pushes the baffle 8, the baffle 8 will eventually be completely misaligned with the parallel block 7. At this time, the user can pull the parallel block 7, which will simultaneously move the drive rods 4 located on both sides of the U-shaped frame 2, thereby changing the position of the limit block 6.

[0028] Multiple anti-slip textures 9 are linearly arranged on the side of the shield 8 facing away from the drive rod 4 to increase the friction between the user's hand and the shield 8, so as to facilitate pushing the shield 8.

[0029] Reference Figure 3 , Figure 4 as well as Figure 5 A limiting member 10 is also connected inside the U-shaped cavity 3. A limiting spring 11 is connected between the limiting member 10 and the U-shaped frame 2. One end of the limiting spring 11 is fixedly connected to the limiting member 10, and the other end of the limiting spring 11 is fixedly connected to the U-shaped frame 2. An arc-shaped groove 12 is also provided at the end of the limiting member 10 that is close to each other.

[0030] When the user inserts the filter bottle into the U-shaped cavity 3, the presence of the arc-shaped groove 12 pushes the limiting member 10, causing the limiting member 10 to move in a direction away from each other until the bottom of the filter bottle contacts the bottom of the U-shaped frame 2. Due to the action of the limiting spring 11, the limiting member 10 always tends to move in the direction of the opposite limiting member 10, thus clamping the filter bottle and stabilizing its bottom.

[0031] The top of the filter bottle is clamped by the limiting block 6, and the body of the filter bottle is clamped by the limiting member 10, thereby enhancing the stability of the filter bottle in the U-shaped cavity 3.

[0032] Reference Figure 1 , Figure 2 A handle 13 is rotatably connected to the end of the U-shaped frame 2, and a storage cavity 14 for inserting the handle 13 is provided at the end of the encapsulation housing 1. When the user needs to push the U-shaped frame 2 using the handle 13, the user can pull the handle 13 out of the storage cavity 14 by grasping the handle 13 located in the storage cavity 14 and continue to apply force to the handle 13, so that the user can easily pull the storage rack out of the encapsulation housing 1.

[0033] A magnetic component 15, which can be magnetically connected to the handle 13, is also bonded to the inner wall of the storage cavity 14. When the user is not using the handle 13, the handle 13 can be attracted by the magnetic component 15, thus confining the handle 13 within the storage cavity 14. At the same time, since the handle 13 attracted by the magnetic component 15 is in contact with both the U-shaped frame 2 and the packaging shell 1, it can also serve to fix the U-shaped frame 2.

[0034] The implementation principle of a water purifier for food safety production disclosed in this application embodiment is as follows: when the user places the filter cartridge 16 into the U-shaped cavity 3, the filter cartridge 16 will first push the limiting member 10, and the limiting member 10 will initially limit the filter cartridge 16. Then the user pushes the drive rod 4, so that the limiting block 6 clamps the filter cartridge 16, thereby realizing the installation of the filter cartridge 16.

[0035] When the user needs to remove the filter cartridge 16 from the U-shaped frame 2, the U-shaped frame 2 must first be pulled out from the encapsulation housing 1, and then the drive rod 4 is pushed to make the limiting block 6 rotate to be misaligned with the filter cartridge 16, so that the filter bottle can be taken out.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
