Description

Technical Field

[0001] This invention relates to the field of disinfection technology, and more specifically, to a medical space disinfection device with acoustic noise reduction. Background Technology

[0002] In medical settings, space disinfection is a crucial step in ensuring the health and safety of patients and healthcare workers. Traditional methods of disinfection in medical spaces are diverse, such as chemical disinfection and ultraviolet disinfection, but these methods have many limitations in practical application.

[0003] Chemical disinfection methods typically involve spraying disinfectant agents. However, some existing disinfection devices have defects in agent mixing, resulting in uneven agent composition and affecting disinfection effectiveness. Furthermore, the diffusion range of the disinfectant is limited during the disinfection process, making it difficult to fully cover every corner of the medical space and ensuring thorough disinfection.

[0004] While ultraviolet disinfection can kill bacteria and viruses to some extent, it is not very effective in disinfecting some hidden corners or areas with shielding. In addition, ultraviolet light can be harmful to the human body, so its use in human environments is limited.

[0005] Furthermore, regardless of the disinfection method, the noise generated during the operation of disinfection equipment cannot be ignored. Hospitals are places that require quiet environments; noise not only affects patients' rest and recovery but may also interfere with the normal work of medical staff. Currently, some disinfection devices on the market are quite noisy during operation and lack effective noise reduction measures, failing to meet the stringent requirements of a quiet medical environment.

[0006] Therefore, a medical space disinfection device that can both improve disinfection effect and effectively reduce noise is proposed. Summary of the Invention

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides an acoustic noise reduction medical space disinfection device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an acoustic noise reduction medical space disinfection device, comprising a shell, a partition installed inside the shell, a drug supply component installed on the partition, a stirring component connected to the drug supply component, a top plate installed at the top of the shell, an air guide block installed at one end of the top plate, side sealing plates installed on both sides of the air guide block, a fixing plate installed between the two side sealing plates, a filter cotton provided at the bottom of one end of the fixing plate, a fan provided inside the filter cotton, two mutually cooperating noise reduction components provided inside the fan, a filter screen installed between the other end of the fixing plate and the air guide block, and an exhaust component provided at the bottom of the filter screen.

[0009] After the disinfectant is placed into the supply unit, the stirring unit operates to agitate the disinfectant, ensuring that all components are evenly mixed. The evenly mixed disinfectant is then drawn into the ventilation duct and sprayed out as a mist. Simultaneously, the fan operates to draw in outside air, which is filtered through filter cotton before entering the ventilation duct. The mist is then blown along the noise reduction channel formed between two noise reduction components. In conjunction with the exhaust unit, the disinfectant is quickly discharged, and the exhaust air velocity is increased, thereby expanding the disinfection range. As the air enters the noise reduction channel, it undergoes multiple turns. At each turn, the noise reduction components absorb the turning force of the air, thus reducing noise and achieving a quiet operation.

[0010] Preferably, the top plate, the two side sealing plates, the fixing plate and the air guide block together form a ventilation duct, and one end of the drug supply component is connected to the bottom of the ventilation duct.

[0011] Preferably, the filter cotton is fixedly connected to a mesh frame, the mesh frame is installed at one end of the ventilation duct, and the filter screen is located at the other end of the ventilation duct.

[0012] Preferably, a soundproof chamber is formed between the top plate and the partition, a cabinet door is provided on one side of the soundproof chamber, and sound-absorbing cotton is attached to the inner wall of the soundproof chamber.

[0013] Preferably, the drug supply assembly includes a drug tank, a delivery pipe, a pump body, and an atomizing nozzle. The drug tank is installed at the bottom of the partition, and the bottom end of the drug tank is connected to the delivery pipe. The delivery pipe is connected to the pump body installed on the partition, and the output end of the pump body is connected to the atomizing nozzle installed inside the ventilation duct.

[0014] Preferably, the top of the medicine container is provided with a fixed cover, the top of the fixed cover is connected and fixed to the partition, the fixed cover is provided with an injection head that passes through the partition, and the injection head is equipped with a sealing cap.

[0015] Preferably, the stirring assembly includes a first motor, a stirring shaft, and stirring rods. The first motor is mounted on a partition plate, and the output end of the first motor is connected to the stirring shaft. Multiple stirring rods are mounted on the stirring shaft.

[0016] Preferably, the noise reduction component includes a sliding plate, a silencing groove, a flow guide plate, a guide rod, a fixing seat, and a spring. The sliding plate has multiple silencing grooves, and a flow guide plate is provided between adjacent silencing grooves. The sliding plate is slidably connected to multiple guide rods, and both ends of the multiple guide rods are connected to the corresponding fixing seats. A spring is sleeved on each guide rod between the fixing seat and the sliding plate.

[0017] Preferably, the two noise reduction components are arranged vertically, with each guide plate inserted into the corresponding silencing slot, so that the two noise reduction components cooperate to form an S-shaped noise reduction channel.

[0018] Preferably, the exhaust assembly includes a second motor, a rotating shaft, and exhaust plates. The second motor is installed on the outside of a corresponding side sealing plate, and a housing is installed on the side sealing plate. The second motor is located inside the housing. The output end of the second motor is connected to a rotating shaft, and multiple exhaust plates are installed on the rotating shaft.

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. The stirring component can be used to stir the disinfectant, ensuring that all components are mixed evenly and guaranteeing the stability of the disinfection effect.

[0021] 2. Outside air is drawn in by a fan, filtered through a filter cotton, and then enters the ventilation duct. This blows the mist-like disinfectant, and in conjunction with the exhaust system, it can quickly expel the disinfectant and increase the exhaust air velocity, thereby expanding the disinfection range and improving disinfection efficiency.

[0022] 3. As air enters the S-shaped noise reduction channel formed by the cooperation of two noise reduction components, the air changes direction multiple times. The noise reduction components can absorb the air turning force and reduce noise. At the same time, the inner wall of the sound insulation chamber between the top plate and the partition is lined with sound-absorbing cotton, which can absorb the noise generated by the operation of the first motor and the pump body, and prevent the noise from being transmitted to the outside world, thus achieving a better overall sound insulation effect.

[0023] 4. The medicine dispenser has a fixed cover on the top of the medicine dispenser with a through-baffle plate and a cabinet door, which makes it easy to open the sealed cover of the medicine dispenser for medicine injection, thus improving the convenience of medicine injection.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] As attached Figure 1-7 The device for acoustic noise reduction and disinfection of medical spaces includes a housing 1, a partition 10 installed inside the housing 1, a drug supply component 11 installed on the partition 10, a stirring component 12 connected to the drug supply component 11, a top plate 2 installed at the top of the housing 1, an air guide block 3 installed at one end of the top plate 2, side sealing plates 4 installed on both sides of the air guide block 3, a fixing plate 5 installed between the two side sealing plates 4, a filter cotton 6 provided at the bottom of one end of the fixing plate 5, a fan 13 provided inside the filter cotton 6, two noise reduction components 14 arranged inside the fan 13, a filter screen 7 installed between the other end of the fixing plate 5 and the air guide block 3, and an exhaust component 15 provided at the bottom of the filter screen 7.

[0034] In practice, after the disinfectant is placed into the supply component 11, the stirring component 12 is activated to stir the disinfectant, ensuring that all components are evenly mixed. The evenly mixed disinfectant is then drawn into the ventilation duct and sprayed out as a mist. Simultaneously, the fan 13 operates to draw in outside air, which is filtered through the filter cotton 6 and then enters the ventilation duct. The mist is then blown along the noise reduction channel formed between the two noise reduction components 14. In conjunction with the exhaust component 15, the disinfectant is quickly discharged, and the exhaust air velocity is increased, thereby expanding the disinfection range. During the process of the air entering the noise reduction channel, the air undergoes multiple turns. At each turn, the noise reduction component 14 absorbs the turning force of the air, thereby reducing noise and achieving a quiet effect.

[0035] The top plate 2, the two side sealing plates 4, the fixing plate 5 and the air guide block 3 together form a ventilation channel, and one end of the drug supply component 11 is connected to the bottom of the ventilation channel.

[0036] The filter cotton 6 is fixedly connected to a mesh frame, which is installed at one end of the ventilation duct, and the filter screen 7 is located at the other end of the ventilation duct.

[0037] A soundproof chamber is formed between the top plate 2 and the partition 10. A cabinet door 9 is provided on one side of the soundproof chamber, and the inner wall of the soundproof chamber is lined with sound-absorbing cotton.

[0038] In practice, by attaching sound-absorbing cotton to the inner wall of the soundproof chamber, the noise generated by the operation of the first motor 1201 and the pump body 1103 can be absorbed, thereby preventing the noise from being transmitted to the outside world and improving the quietness effect. In addition, the cabinet door 9 is set up to facilitate the opening of the sealing cover on the injection head 16 for injection, improving the convenience of injection.

[0039] The drug supply assembly 11 includes a drug tank 1101, a delivery pipe 1102, a pump body 1103, and an atomizing nozzle 1104. The drug tank 1101 is installed at the bottom of the partition 10. The bottom end of the drug tank 1101 is connected to the delivery pipe 1102. The delivery pipe 1102 is connected to the pump body 1103 installed on the partition 10. The output end of the pump body 1103 is connected to the atomizing nozzle 1104 installed inside the ventilation duct.

[0040] The top of the medicine container 1101 is provided with a fixed cover, the top of which is connected and fixed to the partition 10. The fixed cover is provided with an injection head 16 that passes through the partition 10, and a sealing cap is installed on the injection head 16.

[0041] In practice, after the disinfectant is injected into the medicine tank 1101 from the injection head 16, the pump body 1103 is used to extract the disinfectant under the delivery pipe 1102 and then spray it out through the atomizing nozzle 1104 to form an atomization effect. This can be combined with the air blown out by the fan 13 to blow the atomized medicine out of the device and into the medical space for disinfection.

[0042] The stirring assembly 12 includes a first motor 1201, a stirring shaft 1202, and stirring rods 1203. The first motor 1201 is mounted on the partition 10, and the output end of the first motor 1201 is connected to the stirring shaft 1202. Multiple stirring rods 1203 are mounted on the stirring shaft 1202.

[0043] In practice, the operation of the first motor 1201 enables the stirring shaft 1202 to drive each stirring rod 1203 to rotate inside the medicine tank 1101, thereby stirring the disinfectant in the medicine tank 1101 and improving the uniformity of the mixing of the various components of the disinfectant.

[0044] The noise reduction component 14 includes a sliding plate 1401, a noise reduction groove 1402, a flow guide plate 1403, a guide rod 1404, a fixing base 1405, and a spring 1406. The sliding plate 1401 has multiple noise reduction grooves 1402, and a flow guide plate 1403 is provided between adjacent noise reduction grooves 1402. The sliding plate 1401 is slidably connected to multiple guide rods 1404, and both ends of the multiple guide rods 1404 are connected to the corresponding fixing bases 1405. A spring 1406 is sleeved on each guide rod 1404 between the fixing base 1405 and the sliding plate 1401.

[0045] The two noise reduction components 14 are arranged in a vertical arrangement, with each guide plate 1403 inserted into the corresponding silencing slot 1402, so that the two noise reduction components 14 cooperate to form an S-shaped noise reduction channel.

[0046] In practice, after the air blown by the fan 13 enters the ventilation duct, it then enters the noise reduction channel formed by the silent slot 1402 and the guide plate 1403. The air is discharged after being bent multiple times. Each time the air bends and exerts force on the guide plate 1403, the spring 1406 in the direction of the force is compressed, thereby causing the corresponding slide plate 1401 to move. The deformation of the spring 1406 absorbs the kinetic energy of the air, reducing the generation of noise. Furthermore, the movement of the slide plate 1401 changes the diameter of the noise reduction channel, thereby changing the wind speed and further reducing noise.

[0047] The exhaust assembly 15 includes a second motor 1501, a rotating shaft 1502, and an exhaust plate 1503. The second motor 1501 is installed on the outside of the corresponding side sealing plate 4, and a housing 8 is installed on the side sealing plate 4. The second motor 1501 is located inside the housing 8. The output end of the second motor 1501 is connected to the rotating shaft 1502, and multiple exhaust plates 1503 are installed on the rotating shaft 1502.

[0048] In practice, the second motor 1501 operates, which causes the rotating shaft 1502 to rotate, thereby causing the exhaust plate 1503 to rotate as well. During the rotation of the exhaust plate 1503, the air containing the disinfectant is quickly discharged, and the air kinetic energy is increased, thereby increasing the diffusion range of the disinfectant and improving the diffusion efficiency of the disinfectant, thus improving the disinfection effect.

[0049] Finally, the following points should be noted: First, in the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can refer to mechanical connection or electrical connection, or internal connection between two components, or direct connection.
