Description

Technical Field

[0001] This utility model relates to the field of air mixing technology, specifically a binary mixer with self-cleaning function. Background Technology

[0002] A binary gas mixer (also known as a binary gas mixer) is an industrial device that precisely mixes two gases in a set ratio and outputs a stable mixture. It is widely used in food preservation, electronics manufacturing, medical research, and other fields. The following analysis covers its core principles, technology types, application scenarios, and key selection considerations.

[0003] When the existing device is in use, the air pressure will bring the outside dust to the vicinity of the mixer, and then it will adhere to the surface of the controller. The presence of dust can easily obstruct the operating interface, thus affecting the normal use of the mixer.

[0004] To address this, a binary mixer with self-cleaning function is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a binary mixer with a self-cleaning function to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A binary mixer with self-cleaning function includes a mixing cylinder and an operating box, and further includes a sealing plate, a drive mechanism, a push plate, a connecting mechanism, a piston plate, and a nozzle. The sealing plate and the nozzle are both connected to the mixing cylinder. The drive mechanism is connected to the sealing plate, the push plate is connected to the drive mechanism, the connecting mechanism is connected to the push plate, and the piston plate is connected to the connecting mechanism. When gas is injected into the mixing cylinder, the sealing plate moves horizontally under the action of gas pressure, and the drive mechanism controls the push plate to rise and fall. When the push plate rises and falls, the connecting mechanism controls the piston plate to move within the push plate and squeeze the gas toward the nozzle.

[0008] Preferably, the driving mechanism includes a connecting rod, a telescopic spring, a fixed rod, a baffle, a rack, a gear, a screw, a threaded block, and an L-shaped rod. The connecting rod and the rack are both connected to the sealing plate. The telescopic spring is connected to the connecting rod. The fixed rod is connected to the telescopic spring. The baffle is connected to the fixed rod. The gear engages with the rack. The screw is connected to the gear. The threaded block is connected to the screw. The L-shaped rod is connected to the threaded block.

[0009] Preferably, the diameters of the baffle and the sealing plate are the same, and the length of the fixing rod is half of the maximum distance between the baffle and the sealing plate.

[0010] Preferably, the connecting mechanism includes a buffer spring, a guide rod, and a rubber ring. The buffer spring and the guide rod are both connected to the push plate, and the rubber ring is connected to both the push plate and the piston plate.

[0011] Preferably, there are two buffer springs and guide rods symmetrically arranged around the center line of the push plate.

[0012] Preferably, the push plate has an arc-shaped groove inside, the piston plate cooperates with the arc-shaped groove, and the curvature value of the arc-shaped groove is consistent with the curvature value of the piston plate.

[0013] Preferably, the inner wall of the air inlet of the mixing cylinder is provided with air holes, the air holes are arc-shaped, and the diameter of the air hole inlet and outlet is smaller than the thickness of the sealing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] While gas is being added to the mixer, the piston plate moves inside the mixing cylinder to compress the air. The air is then blown onto the control panel under high pressure, which blows away dust from the control panel, ensuring that the control panel remains clean every time it is used. This makes it easier for users to operate the equipment and avoids operational errors. Attached Figure Description

However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0023] Reference Figures 1 to 5 A binary mixer with self-cleaning function includes a mixing cylinder 1 and an operating box 2. The mixing cylinder 1 is one of the core components of the mixer, used to mix two gases. Its material can be a high-strength, corrosion-resistant metal, such as stainless steel. This material has good sealing and pressure resistance, ensuring the stability and safety of the mixing process. The operating box 2 is used by operators to control and monitor the mixer. The outer shell of the operating box 2 can be made of plastic or metal to provide good protection. Internally, it is equipped with an operating panel, controller, etc. The operating panel can be a touch screen for convenient operation and parameter setting. It also includes a sealing plate 3, a drive mechanism 4, a push plate 5, a connecting mechanism 6, a piston plate 7, and a nozzle 8. Both the sealing plate 3 and the nozzle 8 are connected to the mixing cylinder 1. The function of the sealing plate 3 is to achieve specific actions using gas pressure during gas injection. The material of the sealing plate 3 should have good sealing performance and wear resistance; rubber or silicone can be used. Its dimensions are designed based on the air inlet size of the mixing cylinder 1 to ensure a good sealing effect. It is used to blow the compressed high-pressure gas towards the control panel to achieve a self-cleaning function. The nozzle 8 can be made of metal or plastic. The shape and size of its nozzle are designed according to actual needs to ensure that the gas can be blown evenly towards the control panel. The inner wall of the air inlet of the mixing cylinder 1 is provided with air holes 10. The air holes 10 are arc-shaped. The diameter of the inlet and outlet of the air holes 10 is smaller than the thickness of the sealing plate 3. The drive mechanism 4 is connected to the sealing plate 3. The push plate 5 is connected to the drive mechanism 4. The push plate 5 can be made of high-strength plastic or metal. Its size and shape are determined according to actual design requirements. The connecting mechanism 6 is connected to the push plate 5. The piston plate 7 is connected to the connecting mechanism 6. The piston plate 7 should have good sealing and wear resistance. It can be made of rubber or silicone. Its size and shape are designed according to the size of the arc groove 9 inside the push plate 5. The push plate 5 has an arc groove 9 inside, and the piston plate 7 cooperates with the arc groove 9. The curvature value of the arc groove 9 is consistent with the curvature value of the piston plate 7. Through the above settings, it is ensured that the piston plate 7 can move smoothly inside the push plate 5. When gas is added to the mixing cylinder 1, the sealing plate 3 moves horizontally under the action of air pressure and the push plate 5 is raised and lowered by the drive mechanism 4. When the push plate 5 is raised and lowered, the connecting mechanism 6 controls the piston plate 7 to move inside the push plate 5 and squeeze the gas towards the nozzle 8.

[0024] As one embodiment of this utility model, refer to Figures 3 to 5 The drive mechanism 4 includes a connecting rod 41, a telescopic spring 42, a fixed rod 43, a baffle 44, a rack 45, a gear 46, a screw 47, a threaded block 48, and an L-shaped rod 49. The connecting rod 41 and the rack 45 are both connected to the sealing plate 3. The telescopic spring 42 is connected to the connecting rod 41, and the fixed rod 43 is connected to the telescopic spring 42. The fixed rod 43 and the baffle 44 are used to limit the movement range of the sealing plate 3 to ensure the stability of the mechanism. The telescopic spring 42 is used to provide buffering and reset. The baffle 44 is connected to the fixed rod 43. The gear 46 cooperates with the rack 45. The translation of the sealing plate 3 drives the rack 45 to move, converting linear motion into rotational motion. The screw 47 is connected to the gear 46. The rotational motion is converted into linear motion through the threaded block 48, thereby controlling the lifting and lowering of the push plate 5. The materials of each component can be metal materials, such as carbon steel or aluminum alloy, to ensure their strength and wear resistance. The threaded block 48 is connected to the screw 47, the L-shaped rod 49 is connected to the threaded block 48, the diameter of the baffle 44 is the same as that of the sealing plate 3, and the length of the fixing rod 43 is half of the maximum distance between the baffle 44 and the sealing plate 3.

[0025] As one embodiment of this utility model, refer to Figure 5 The connecting mechanism 6 includes a buffer spring 61, a guide rod 62, and a rubber ring 63. Both the buffer spring 61 and the guide rod 62 are connected to the push plate 5. The rubber ring 63 is connected to both the push plate 5 and the piston plate 7. The rubber ring 63 can be made of rubber or silicone. Through the above arrangement, it can play a role in sealing and buffering. There are two buffer springs 61 and two guide rods 62 symmetrically arranged around the center line of the push plate 5. Through the above arrangement, it is used to ensure the smooth movement of the piston plate 7. The elastic coefficient of the buffer spring 61 and the size of the guide rod 62 are selected according to actual needs.

[0026] Working principle: When gas is added to the mixing cylinder 1, the gas pressure acts on the sealing plate 3, causing the sealing plate 3 to move horizontally. The horizontal movement of the sealing plate 3 drives the connecting rod 41 and rack 45 of the drive mechanism 4 to move. The rack 45 drives the gear 46 to rotate, and the gear 46 drives the screw 47 to rotate. The screw 47 converts the rotational motion into linear motion through the threaded block 48, causing the L-shaped rod 49 to rise and fall, thereby controlling the rise and fall of the push plate 5. When the push plate 5 rises and falls, the connecting mechanism 6 controls the piston plate 7 to move within the push plate 5, squeezing the gas towards the nozzle 8. The high-pressure gas is blown towards the control panel through the nozzle 8, achieving the self-cleaning function.

[0027] Although the embodiments of this utility model have been described in detail with reference to the accompanying drawings, those skilled in the art can make changes, modifications, substitutions and variations to these embodiments without departing from the principles and spirit of this utility model. The appended claims and their equivalents define the scope of this utility model.
