Hydrogen peroxide, with its advantages of safety, no pollution, and no residue, has become a widely used sterilization gas. Existing sterilization equipment typically uses fans to blow hydrogen peroxide vapor into the space to be sterilized. However, the fans only serve a blowing function and cannot achieve effective diffusion of the sterilizing gas within the room, thus affecting the final sterilization effect.

[0003] In summary, developing a sterilization nozzle and cleanroom that can fully diffuse and transport sterilization steam is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a sterilization nozzle and a cleanroom, which solves the technical problem that existing sterilization equipment is unable to fully diffuse sterilization steam, resulting in a limited sterilization area and sterilization dead zones.

[0005] To achieve the above objectives, this utility model provides a sterilization nozzle, comprising:

[0006] The connecting pipe has two parallel spray nozzles connected to its two ends. Each spray nozzle is perpendicular to the connecting pipe. Each spray nozzle has a guide groove extending from its port towards the side closer to the connecting pipe. The guide groove is located inside the spray nozzle. A guide pipe is fitted inside the spray nozzle, and the end of the guide pipe extends into the guide groove. The guide pipe and the spray nozzle are clamped together to form a guide chamber that communicates with the guide groove.

[0007] Preferably, the spray nozzle and guide pipe on one side of the connecting pipe are integrated as a whole, and the spray nozzle and guide pipe on the other side of the connecting pipe are integrated as another whole. The diameters of the two are set in a preset ratio, and each guide groove is located on both sides of the connecting pipe along the axis of the spray nozzle.

[0008] Preferably, each guide tube has a connecting section, the outer wall of the connecting section is fitted and fixed to the inner cavity of the spray nozzle, and a contraction section extends from the end of the connecting section near the guide groove. The contraction section is connected to an outlet section, and the outlet section is coaxially arranged with the connecting section. The outlet section extends into the guide groove, dividing the guide groove into a first chamber and a second chamber that are connected. The first chamber is connected to the guide chamber, and the second chamber is connected to the inner cavity of the guide tube.

[0009] Preferably, the through hole connecting the pipe and the spray nozzle corresponds to the contraction section.

[0010] A cleanroom includes the sterilization nozzles described above, and further includes a first compartment and a second compartment. The top plates of the first compartment and the second compartment are each fixed with a conveying pipe on the side near the inner cavity, and one end of the conveying pipe is connected to two sterilization nozzles.

[0011] Preferably, the two ends of the conveying pipeline are spliced ​​with a first bend pipe and a second bend pipe respectively. The first bend pipe passes through the top plate of the first compartment and the second compartment and is connected to the sterilization steam generator. The bending direction of the second bend pipe is opposite to that of the first bend pipe. The end of the second bend pipe extends to both sides perpendicular to its axis and is connected to two sterilization nozzles. The two sterilization nozzles are symmetrical about the axis of the second bend pipe.

[0012] Preferably, each of the first bends is fitted with two fixed flanges, which are clamped on both sides of the top plate, and the fixed flanges fix each of the second bends to the top plates of the first and second compartments.

[0013] Preferably, a number of hanging brackets are fitted around the outer periphery of the conveying pipeline, and each hanging bracket is fixedly connected to the top plate of the first compartment and the second compartment.

[0014] Preferably, a regulating valve is connected to one end of the first bent pipe that extends out of the top plate of the first compartment and the second compartment. The regulating valve controls the connection and disconnection between the sterilization steam generator and the first bent pipe.

[0015] Preferably, the first compartment and the second compartment can be spliced ​​together, and several conveying pipes can be spliced ​​between the first bend pipe and the second bend pipe to adjust the position of the sterilization nozzle in the first compartment and the second compartment.

[0016] Compared to the aforementioned background technology, the sterilization nozzle provided by this utility model includes: a connecting pipe, with two spray cylinders connected to each end of the connecting pipe respectively. The connecting pipe is perpendicular to each spray cylinder, and the two ends of the connecting pipe are connected to the side walls of each spray cylinder. Sterilization steam is diverted to the two spray cylinders through the connecting pipe. The ends of each spray cylinder extend and bend towards their inner cavity to form an annular guide groove. In addition, a guide tube is sleeved inside each spray cylinder, with the end of the guide tube extending into the guide groove. The outer wall of the guide tube and the inner wall of the spray cylinder are clamped to form a guide chamber, and the guide chamber extends into the guide groove and... The inner cavity of the guide channel is interconnected. During sterilization, sterilizing steam is transported to each spray nozzle through connecting pipes. The sterilizing steam enters the guide chamber formed by the spray nozzle and the guide pipe. The guide chamber is connected to the inner cavity of the guide channel. The sterilizing gas enters the guide channel through the guide chamber. After passing through the guide channel, the sterilizing steam flows in the opposite direction. The sterilizing gas flows along the inner wall of the guide pipe towards the end away from the guide channel. The sterilizing gas flowing at the inner wall of the guide pipe creates a negative pressure in the sterilization nozzle. The negative pressure draws out the air in the room, causing the air and sterilizing gas to mix and flow together, and then spray out from the end of the sterilization nozzle.

[0017] The sterilization nozzle provided in this application draws in indoor air while blowing out sterilization steam. The sterilization nozzle forms a circulating airflow in the room to be sterilized, making it easier for the sterilization steam to reach sterilization dead corners and improving the sterilization effect.

Detailed Implementation

[0026] 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.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This application provides a sterilization nozzle; please refer to the attached instruction manual. Figure 3 With appendix Figure 4 The sterilization nozzle includes a connecting pipe 1 for conveying sterilizing steam. Spray cylinders 2 are connected to both ends of the connecting pipe 1. The spray cylinders 2 are parallel to each other, and their axes are perpendicular to the axis of the connecting pipe 1. The port of the connecting pipe 1 passes through the side wall of each spray cylinder 2 and communicates with the inner cavity of each spray cylinder 2. The cylinder wall at one port of each spray cylinder 2 extends towards the axis of the spray cylinder 2 and bends towards the connecting pipe 1, creating a guide groove 3 inside the port of the spray cylinder 2. Furthermore, a guide tube 4 is sleeved inside the spray cylinder 2, coaxially arranged with the spray cylinder 2. The outer wall of the guide tube 4 and the inner wall of the spray cylinder 2 clamp together to form a guide chamber 5. The sterilizing steam in the connecting pipe 1 fills the guide chamber 5. It should be noted that the end of the guide tube 4 extends into the guide groove. Inside the 3, the flow chamber 5 formed by the flow guide pipe 4 and the spray cylinder 2 is connected to the flow guide trough 3. During sterilization, sterilization steam enters the spray cylinder 2 through the connecting pipe 1. The flow chamber 5 guides the sterilization steam into the flow guide trough 3. The sterilization steam flows along the inner wall of the flow guide trough 3 and enters the inner cavity of the flow guide pipe 4. At this time, the sterilization steam flows along the inner wall of the flow guide pipe 4. The flowing sterilization steam creates a negative pressure in the inner cavity of the flow guide pipe 4, drawing air located on one side of the flow guide trough 3 into the inner cavity of the sterilization nozzle. The air is sprayed out along with the sterilization steam. During the process of blowing sterilization steam, the sterilization nozzle forms a circulating airflow in the room to be sterilized, ensuring that the air in the room and the sterilization steam are fully mixed, and the sterilization steam can diffuse to any corner of the room to be sterilized with the circulating airflow.

[0029] Please refer to the instruction manual appendix. Figure 4The spray nozzles 2 and guide pipes 4 located on both sides of the connecting pipe 1 are proportionally sized. The larger spray nozzle 2 and guide pipe 4 are designated as the first spray nozzle and first guide pipe, and the smaller one as the second spray nozzle and second guide pipe. Since the connecting pipe 1 connecting the first and second spray nozzles has the same port size, the volume of sterilizing steam entering the first and second spray nozzles is the same within the same time frame. However, the backflow chamber formed by the second guide pipe and the second spray nozzle is smaller, resulting in a higher velocity of the sterilizing steam ejected from the second spray nozzle and a longer steam propagation distance. In contrast, the first spray nozzle and the second guide pipe... The first guide tube is relatively large, and the negative pressure formed inside the first guide tube can draw in more indoor air, accelerating the mixing rate of indoor air and sterilizing steam. In addition, the guide channels set in the first and second spray tubes are respectively referred to as the first guide channel and the second guide channel. The first guide channel and the second guide channel are located on both sides of the connecting pipe 1 along the axis of the spray tube 2. That is to say, the blowing directions of the first guide channel and the second guide channel are opposite, which increases the spray range of the sterilization nozzle and avoids the airflow blown by the first guide channel and the second guide channel from interfering with each other and affecting the sterilization range of the sterilization nozzle.

[0030] Please refer to the instruction manual appendix. Figure 5 The guide pipe 4 specifically includes a connecting section 41, a contraction section 42, and an outlet section 43. The connecting section 41, contraction section 42, and outlet section 43 are arranged sequentially along the side closest to the guide channel 3. The connecting section 41, outlet section 43, and guide channel 3 are all coaxially arranged. The outer wall of the connecting section 41 abuts against the inner wall of the spray nozzle 2, fixing the guide pipe 4 to the spray nozzle 2. The contraction section 42 is connected to the connecting section 41, and its diameter gradually decreases towards the side away from the connecting section 41. The outlet section 43 is connected to the gradually decreasing end of the contraction section 42. The outlet section 43 extends into the inner cavity of the guide channel 3, but does not contact the side wall of the guide channel 3. The outlet section 43 divides the inner cavity of the guide channel 3 into a first chamber 6 and a second chamber 7, with the second chamber 7 located away from the guide channel 3. The first chamber 6 of the axis is connected to the guide chamber 5, guiding the sterilizing steam into the guide groove 3. Guided by the guide groove 3, the sterilizing steam is ejected from the second chamber 7. The sterilizing steam flows along the inner wall of the guide pipe 4 and is blown out from the port of the guide pipe 4 away from the guide groove 3. It should be noted that the through hole connecting the connecting pipe 1 and the spray nozzle 2 corresponds to the constriction section 42 of the guide pipe 4, so that the sterilizing steam in the connecting pipe 1 can smoothly enter the guide chamber 5. In addition, as the sterilizing steam flows along the inner wall of the guide chamber 5, the pressure in the area of ​​the inner cavity of the guide pipe 4 near the axis decreases. The low-pressure area draws in outside air and blows it out along with the sterilizing steam. The sterilizing nozzle forms a circulating airflow while blowing the sterilizing steam, which assists in the diffusion of the sterilizing steam.

[0031] This application also provides a cleanroom; please refer to the attached instruction manual. Figure 1 With appendix Figure 2The cleanroom includes a first compartment 8 and a second compartment 9. A conveying pipe 13 is installed inside the first compartment 8 and the second compartment 9. Several hanging brackets 15 are installed around the conveying pipe 13, each bracket fixing the conveying pipe 13 to the ceiling. A first bent pipe 10 and a second bent pipe 11 are respectively installed at both ends of the conveying pipe 13. The first bent pipe 10 passes through the ceiling and connects to a sterilization steam generator (not shown in the figure) outside the cleanroom, allowing sterilization steam to enter the conveying pipe 13. Preferably, two fixed flanges 12 are fitted around the outer periphery of the first bent pipe 10, each fixed flange 12... Fasteners are inserted between the fixed flanges 12 on both sides of the top plate to clamp the top plate, ensuring that the first bent pipe 10 is securely installed. The bending direction of the second bent pipe 11 is opposite to that of the first bent pipe 10. Branch pipes extend to both sides from the end of the second bent pipe 11. Each branch pipe is perpendicular to the bent part of the bent pipe. The end of each branch pipe is connected to a sterilization nozzle. The two sterilization nozzles are symmetrical about the axis of the bent part of the second bent pipe 11, that is, the blowing direction of each sterilization nozzle is opposite, which further expands the sterilization range of each sterilization nozzle and improves the sterilization efficiency of the sterilization nozzle.

[0032] Preferably, a regulating valve 14 is provided in the portion of the first bend pipe 10 extending into the inner cavity of the first chamber 8 and the second chamber 9. The regulating valve 14 can be a manual valve or an electric valve, and the regulating valve 14 controls the flow rate of sterilizing steam entering the conveying pipe 13.

[0033] Preferably, the first chamber 8 and the second chamber 9 can be spliced ​​together, and several conveying pipes 13 can be spliced ​​between the first bent pipe 10 and the second bent pipe 11. The distance between the first bent pipe 10 and the sterilization nozzle can be adjusted, and the sterilization nozzle can be adjusted to a suitable position according to the sterilization scenario of different area to ensure that the sterilization efficiency of the sterilization nozzle is maximized.

[0034] In one embodiment of this utility model, the number of compartments constituting the clean room is several, that is, the clean room has more than just the first compartment 8 and the second compartment 9. Each compartment is equipped with a regulating valve 14 between itself and each sterilization steam generator. Preferably, each regulating valve 14 is connected to the central control system. By controlling the amount of sterilization steam in each compartment through the central control system, it is possible to achieve individual sterilization or simultaneous sterilization of several specific compartments in the clean room, which further improves the applicability of this application.

[0035] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0036] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
