Description

Technical Field

[0001] This utility model relates to the field of disinfection and sterilization technology, and in particular to a gas path connection structure for a hydrogen peroxide disinfection machine. Background Technology

[0002] Traditional disinfection methods suffer from low efficiency and potential residue risks. Hydrogen peroxide, with its strong oxidizing properties, can effectively sterilize. By combining automated control and atomization technology, equipment has been developed that can precisely control concentration and dosage and achieve disinfection without dead angles in the space, meeting the needs of medical, food and other scenarios for efficient and safe disinfection.

[0003] In existing technologies, the hydrogen peroxide disinfection machine uses a liquid storage tank for supplying hydrogen peroxide that is fixed inside the machine. This results in the need for tools or opening the lid for replenishing the liquid, a cumbersome process that is difficult to clean, and the liquid is prone to residue and deterioration. Furthermore, the lack of pretreatment of the transported liquid leads to problems such as precipitation, stratification, and uneven solution quality during long-term storage.

[0004] To address this, a gas path connection structure for a hydrogen peroxide sterilizer is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a gas circuit connection structure for a hydrogen peroxide sterilizer, which can solve the problems of cumbersome replacement of existing storage tanks and uneven solution quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas circuit connection structure for a hydrogen peroxide sterilizer, including a sterilizer body, a placement groove is provided on the front side of the sterilizer body, a partition is fixedly connected to the inner side of the placement groove, a convenient replacement mechanism is movably connected to the inner side of the partition, and a pre-mixing mechanism is provided on the top of the convenient replacement mechanism.

[0007] The convenient replacement mechanism includes a limiting box fixedly connected to the inner side of the partition. A fixing box is fixedly connected to the bottom of the limiting box. A liquid storage tank is movably connected to the inner side of both the limiting box and the fixing box. Sliding rails are fixedly connected to both sides of the bottom of the fixing box. Sliding paddles are slidably connected to the inner side of each of the two sliding rails. Elastic contact components are movably connected to the opposite side of each of the two sliding paddles. A fixing soft block is movably connected to the inner side of each elastic contact component. A support block is fixedly connected to the bottom of the fixing box. Telescopic columns are fixedly connected to the opposite side of each sliding paddle and support block. A tension spring is fixedly connected to the inner side of each telescopic column.

[0008] Preferably, a temporary storage tank is provided on the top of the limiting box, and a liquid pump is fixedly connected to the bottom of the temporary storage tank.

[0009] Preferably, a support ring frame is fixedly connected to the top of the inner side of the temporary storage tank.

[0010] Preferably, small servo motors are fixedly connected to both sides of the top of the support ring frame, and a spiral guide rod is fixedly connected to the output end of the small servo motor.

[0011] Preferably, the elastic contact assembly includes a support plate fixedly connected to the top of the sliding paddle, a first telescopic rod fixedly connected to the side of the support plate near the fixed box, a buffer plate fixedly connected to the side of the first telescopic rod near the fixed box, a second telescopic rod fixedly connected to the side of the buffer plate near the fixed box, and a fixing soft block fixedly connected to the side of the second telescopic rod near the fixed box.

[0012] Preferably, compression springs are fixedly connected to the inner sides of both the first and second telescopic rods.

[0013] Preferably, an infusion hose is movably connected to the top of the storage tank, and the infusion hose is fixedly connected to the bottom of the pump.

[0014] Preferably, an infusion pipe is fixedly connected to the top of the storage tank, and the infusion pipe is fixedly connected to the top of the inner side of the placement tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application, by setting up a convenient replacement mechanism, allows for the direct replacement of the entire liquid storage tank without the need for tools. This solves the cumbersome process of opening the lid and replenishing the liquid in traditional fixed liquid storage tanks with tools, and avoids the leakage problems that may be caused by pouring liquid for replenishment. At the same time, the split design allows the liquid storage tank to be independently scrapped or recycled for cleaning, eliminating the risk of liquid residue deterioration caused by long-term fixation inside the machine and difficulty in cleaning. Furthermore, the elastic buffer structure reduces the clamping stress through two waves of buffering during fixation, preventing deformation and damage to the lightweight liquid storage tank. This fundamentally optimizes the problems of replacing, replenishing, and cleaning the liquid storage tank.

[0017] 2. This application optimizes the liquid transmission path by setting up a premixing mechanism, which is from the storage tank to the infusion hose to the temporary storage tank to the infusion tube. After the liquid in the storage tank is drawn into the temporary storage tank by the liquid pump, the small servo motors on both sides of the support ring drive the spiral guide rod to perform spiral flow and stirring of the liquid. The liquid is homogenized and pretreated by bottoming out and rebounding. This effectively solves the problem of sedimentation and stratification and uneven solution quality caused by long-term storage of liquid without pretreatment. It ensures that the liquid composition entering the disinfection machine is uniform and stable, and guarantees the disinfection effect from the source. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A gas circuit connection structure for a hydrogen peroxide sterilizer includes a sterilizer body 1, a placement slot 2 is provided on the front side of the sterilizer body 1, a partition 3 is fixedly connected to the inner side of the placement slot 2, a convenient replacement mechanism 4 is movably connected to the inner side of the partition 3, and a premixing mechanism 5 is provided on the top of the convenient replacement mechanism 4.

[0027] The convenient replacement mechanism 4 includes a limiting box 41 fixedly connected to the inside of the partition 3. A fixing box 42 is fixedly connected to the bottom of the limiting box 41. A liquid storage tank 43 is movably connected to the inside of both the limiting box 41 and the fixing box 42. Sliding rails 44 are fixedly connected to both sides of the bottom of the fixing box 42. Sliding paddles 45 are slidably connected to the inside of both sliding rails 44. Elastic contact components 46 are movably connected to the opposite side of both sliding paddles 45. A fixing soft block 47 is movably connected to the inside of the elastic contact components 46. A support block 48 is fixedly connected to the bottom of the fixing box 42. Telescopic columns 49 are fixedly connected to the opposite side of both sliding paddles 45 and support blocks 48. A tension spring 410 is fixedly connected to the inside of the telescopic columns 49.

[0028] In this embodiment: First, the old liquid storage tank 43 is removed and the two sets of sliding paddles 45 at the bottom of the fixing box 42 are manually opened, so that it slides along the sliding rail 44 to the side away from the center of the fixing box 42. At this time, the telescopic column 49 between the sliding paddle 45 and the support block 48 at the center of the bottom of the fixing box 42 is stretched and the internal tension spring 410 is tightened to generate a pull-back elastic potential energy. Then, the new liquid storage tank 43 is inserted through the limiting box 41 and slid downward. After its bottom contacts the bottom of the fixing box 42, the sliding paddle 45 is released, so that it moves closer to the liquid storage tank 43 under the pull-back of the tension spring 410. At the same time, the fixed soft block 47 at the top of the sliding paddle 45, which is supported by the elastic element, weakens the clamping stress through the two waves of buffering of the elastic contact component 46, so as to avoid deformation and damage of the lightweight liquid storage tank 43. Thus, the replacement of the liquid storage tank 43 is optimized without the need for additional liquid replenishment tools, without tipping and liquid replenishment leakage, and without internal liquid residue.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a temporary storage tank 51 is provided on the top of the limiting box 41, and a liquid pump 52 is fixedly connected to the bottom of the temporary storage tank 51.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a support ring frame 53 is fixedly connected to the top of the inner side of the temporary storage tank 51.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, small servo motors 54 are fixedly connected to both sides of the top of the support ring frame 53, and spiral guide rods 55 are fixedly connected to the output ends of the small servo motors 54.

[0032] In this embodiment: when supplying liquid to the storage tank 43, the liquid inside the storage tank 43 is drawn into the temporary storage tank 51 by the liquid pump 52 through the infusion hose 6. The small servo motors 54 on both sides of the support ring frame 53 at the top of the temporary storage tank 51, which does not affect the liquid collection area of ​​the infusion tube 7, drive the spiral guide rod 55 with the external guide thread shape at the bottom to guide the liquid to the top in a spiral form, and then bounce back to the upper layer after hitting the bottom, so as to perform homogenization pretreatment of the liquid. Then, the liquid is supplied from the mixing area at the bottom of the temporary storage tank 51 through the extraction structure of the sterilizer body 1 by the infusion tube 7, thereby realizing the pretreatment of the new liquid.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, the elastic contact assembly 46 includes a support plate 46a fixedly connected to the top of the sliding paddle 45, a first telescopic rod 46b fixedly connected to the side of the support plate 46a near the fixed box 42, a buffer plate 46c fixedly connected to the side of the first telescopic rod 46b near the fixed box 42, a second telescopic rod 46d fixedly connected to the side of the buffer plate 46c near the fixed box 42, and a fixing soft block 47 fixedly connected to the side of the second telescopic rod 46d near the fixed box 42.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, compression springs 46e are fixedly connected to the inner sides of both the first telescopic rod 46b and the second telescopic rod 46d.

[0035] In this embodiment: when the fixing soft block 47 contacts the bottom sides of the liquid storage tank 43 from both sides and fixes the bottom ends of the tank from both sides, the fixing soft block 47 deforms after contacting the outer wall of the liquid storage tank 43 and fits firmly against the inner wall. At the same time, the sliding paddle 45 continues to move towards one side of the liquid storage tank 43. At this time, the second telescopic rod 46d between the fixing soft block 47 and the buffer plate 46c and the inner compression spring 46e will perform the first wave of push-back buffering. While maintaining the push-forward, the first telescopic rod 46b at the bottom of the buffer plate 46c and the inner compression spring 46e will perform the second wave of contraction buffering. Through the two waves of buffering, the clamping stress of the fixing soft block 47 is weakened, and the lightweight liquid storage tank 43 is prevented from deforming and being damaged.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, an infusion hose 6 is movably connected to the top of the storage tank 43, and the infusion hose 6 is fixedly connected to the bottom of the pump 52.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, the top of the storage tank 43 is fixedly connected to the infusion pipe 7, which is fixedly connected to the top of the inner side of the placement tank 2.

[0038] In this embodiment, the liquid inside the storage tank 43 and the temporary storage tank 51 can be supplied and transferred through the infusion hose 6 and the infusion tube 7 to achieve liquid supply.

[0039] Working Principle: In medical environments, hydrogen peroxide sterilizer body 1 is typically used to disinfect hospital environments. In existing technology, sodium hydroxide liquid is usually supplied through the internal storage tank 43 of sterilizer body 1, and the reaction is achieved in conjunction with other gas passage structures within sterilizer body 1 to perform the disinfection operation. However, when the hydrogen peroxide stock solution in storage tank 43 is depleted, special tools or opening the flip-top to pour out the liquid is required for replenishment, making the replenishment process cumbersome and requiring many specific steps. Furthermore, since storage tank 43 is permanently fixed inside the sterilizer, and replenishment is also in a sealed state, it is difficult to clean the stock solution inside. Long-term residue inside storage tank 43 can easily deteriorate, affecting the quality of new solution and the disinfection effect. To prevent these issues, a split-type... The lightweight and easily replaceable liquid storage tank 43 allows for easy replacement when the original liquid inside is depleted. Simply replace it with another tank 43 filled with the original liquid. The replaced tank 43 can then be scrapped or recycled for cleaning. When replacement is needed, first remove the depleted tank 43, then manually open the two sets of sliding paddles 45 located at the bottom of the fixing box 42. This causes the sliding paddles 45 to slide along the sliding rail 44 to the side away from the center of the fixing box 42. During this sliding, the telescopic column 49 between the sliding paddles 45 and the support block 48 at the bottom and center of the fixing box 42 will stretch, and the internal tension spring 410 will tighten and release its elastic potential energy. Meanwhile, the other hand moves the liquid storage tank 43 through the limiting box 4. 1. After the sliding plate 45 slides downward and contacts the bottom of the fixed box 42 at the bottom of the liquid storage tank 43, the pressure on the sliding lever 45 is released, causing it to move towards the liquid storage tank 43 under the pull of the tension spring 410. A fixed soft block 47 supported by an elastic element is provided on the top of the sliding lever 45. When the fixed soft block 47 contacts the bottom sides of the liquid storage tank 43 from both sides and fixes its bottom ends on both sides, the overall transmission path of its outer elastic element is as follows: First, when the fixed soft block 47 contacts the outer wall of the liquid storage tank 43, the fixed soft block 47 deforms and fits against the inner wall and makes firm contact. In this state, the sliding lever 45 still moves towards one side of the liquid storage tank 43. At this time, the second telescopic rod 46d between the fixed soft block 47 and the buffer plate 46c and the compression spring 46e on its inner side... The system will perform a first wave of back-pushing buffering. While maintaining the forward movement, the buffer plate 46c and the first telescopic rod 46b at the bottom of the sliding paddle 45, along with their inner compression spring 46e, will perform a second wave of contraction buffering. Through these two waves of buffering, the clamping stress on the fixed soft block 47 is weakened, preventing deformation and damage to the lightweight liquid storage tank 43. In summary, this optimizes the replacement of the liquid storage tank 43, eliminating the need for additional liquid replenishment tools, and avoiding leakage problems and internal liquid residue issues during tipping and replenishment. When supplying liquid to the liquid storage tank 43, it is usually supplied directly to the remaining air passage structure of the sterilizer body 1 through the infusion pipe 7. However, the new liquid is not pre-treated, and the new liquid is prone to sedimentation and stratification during long-term storage, leading to uneven solution quality in subsequent use.Therefore, a temporary storage tank 51 for pre-mixing is required before the liquid is transferred to the inside of the sterilizer body 1. The overall transfer path is changed from the storage tank 43 to the infusion tube 7 to the sterilizer body 1 to the storage tank 43 to the infusion tube 6 to the temporary storage tank 51 and then into the sterilizer body 1 through the infusion tube 7. After the liquid inside the storage tank 43 is drawn into the temporary storage tank 51 by the pump 52, a support ring 53 is provided at the top of the temporary storage tank 51 to support the liquid collection in the infusion tube 7. Small servo motors 54 are installed on both sides of the 3 unit, and a spiral guide rod 55 with an external guide thread shape is installed at the bottom of the small servo motor 54. This guide rod can guide the liquid to the top in a spiral shape and bounce back to the upper layer after touching the bottom to repeat the process, thereby homogenizing the new liquid. Then, the infusion pipe 7 supplies liquid from the mixing area at the bottom of the temporary storage tank 51 through the extraction structure of the sterilizer body 1, thereby realizing the pretreatment of the new liquid. In summary, the gas circuit connection structure of the hydrogen peroxide sterilizer is optimized.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
