Description

Technical Field

[0001] The present invention relates to the technical field of incubators, in particular to the technical field of an incubator capable of automatically sterilizing. Background Art

[0002] An incubator is a device used to culture microorganisms, cells or biological samples. It usually has control functions such as constant temperature, constant humidity, and constant oxygen, and can provide environmental conditions suitable for biological growth and reproduction.

[0003] However, the existing incubator has a simple structure, single function, and the temperature control cannot meet the needs of experiments or scientific research, thereby reducing work efficiency.

[0004] To address the problems raised in the above-mentioned technologies, for example, application number CN201220681690.8 discloses an incubator comprising a housing with a door, a grooved inner container disposed within the housing, a movable partition mounted within the inner container, a temperature probe, and a temperature controller, a power supply unit connected to the temperature controller, and an LCD and alarm disposed on the outside of the housing; the LCD is connected to the temperature controller; and the alarm is connected to the temperature probe. The incubator of this utility model simultaneously has functions such as temperature control, alarm, temperature setting, temperature display, and data recording, thus expanding its application range. Furthermore, it can be powered by a household power supply or a rechargeable battery, thus avoiding test failures due to power outages.

[0005] However, the incubator in the above patent does not have a disinfection function, which makes it easy for bacteria to grow inside the incubator, thereby causing the bacteria grown in the incubator to easily contaminate the microorganisms to be cultured.

[0006] To solve the problems raised in the above-mentioned technology, for example, application number CN201621237657.0 discloses a sterilizable incubator, comprising a box body, which is a commonly used incubator on the market, a door panel located at the front end of the box body, and a temperature control panel above the front end door panel of the box body. A fluorescent lamp switch and an ultraviolet lamp switch fixed to the box body are provided next to the temperature control panel. An ultraviolet lamp is provided on the side of the rear side of the top surface of the rectangular cavity in the box body, and an ultraviolet lamp is provided on the side of the front of the bottom surface of the rectangular cavity in the box body. A fluorescent lamp is provided on the side of the front of the top surface of the rectangular cavity in the box body, and a fluorescent lamp is provided on the side of the rear side of the bottom surface of the rectangular cavity in the box body; the upper and lower fluorescent lamps are arranged on opposite sides, and the upper and lower ultraviolet lamps are arranged on opposite sides. Before culturing microorganisms, the ultraviolet lamp control switch on the control panel is turned on to disinfect the incubator. After the disinfection time is reached, the ultraviolet lamp is turned off to make the incubator sterile. Then the microorganisms to be cultured are placed in the incubator body, thereby avoiding the phenomenon that the microorganisms remaining in the incubator body contaminate the microorganisms to be cultured.

[0007] However, the above patent still has the following defects: Although the above patent uses ultraviolet lamps to disinfect the inside of the box, the linear propagation characteristics of ultraviolet rays make it impossible to effectively cover the corners and gaps of the box, resulting in the problem of dead corners for disinfection, which leads to incomplete disinfection.

[0018] Beneficial effects of the present invention: 1. The present invention can achieve dead-angle disinfection through the cooperation of the disinfection box, the liquid extraction pump, the liquid extraction disinfection pipe, the liquid transfer disinfection pipe, the liquid separation disinfection pipe and the spray head. The disinfection liquid in the disinfection box is extracted by the liquid extraction pump and pressure is applied to the liquid. The pressurized disinfectant is forcibly transported to the liquid separation disinfection pipe through the liquid transfer disinfection pipe, and then transmitted to each spray head through the liquid separation disinfection pipe. When the pressurized disinfectant enters the internal cavity of the spray head, the pressurized liquid is forced to pass through a plurality of fine injection holes at the end of the nozzle. When the liquid flows out of the small holes, due to the surface tension and the friction and shearing effect of the high-speed jet and the surrounding air, the jet is unstable and broken into droplets, so that the disinfectant is sprayed from the nozzle of the spray head in a mist form composed of a large number of tiny droplets, forming a spray field with a wider diffusion range and more uniform coverage, so that the atomized particles can penetrate hidden areas such as gaps and corners of the box, thereby achieving dead-angle disinfection. 2. The present invention can volatilize the residual disinfectant through the joint cooperation of the blower, heating box, air transmission duct, heating element, exhaust fan, exhaust duct and air outlet duct. When the box is disinfected, some disinfectant remains inside. If the residual disinfectant is not volatilized in time, it will easily affect the subsequent culture effect of the incubator. When the blower is started, the inhaled air is transported to the heating box through the air transmission duct. The air is heated by the heating element in the heating box and converted into hot air. At this time, the exhaust fan draws out the hot air in the heating box through the exhaust duct, and transports the hot air to the air outlet through the air outlet duct, so that the hot air is blown out from the air outlet, thereby indirectly heating the residual disinfectant in the box, thereby increasing the kinetic energy of the liquid molecules to accelerate volatilization.

DETAILED DESCRIPTION

[0020] See Figures 1 to 5 The present invention relates to an incubator capable of automatic disinfection, comprising a box body 1, a placement plate 2, a support plate 3, a disinfection mechanism 4, a disinfection box 41, a liquid extraction pump 42, a liquid extraction disinfection pipe 43, a liquid transmission disinfection pipe 44, a liquid separation disinfection pipe 45, a spray head 46 and a volatilization mechanism 5; a placement plate 2 is provided inside the box body 1, a support plate 3 is installed on the right side surface of the box body 1, and a disinfection mechanism 4 is provided on the support plate 3; the disinfection mechanism 4 comprises a disinfection box 41, a liquid extraction pump 42, a liquid extraction disinfection pipe 43, a liquid transmission disinfection pipe 44, a liquid separation disinfection pipe 45 and a spray head 46 and a volatilization mechanism 5 Head 46, the disinfection box 41 and the liquid pump 42 are located on the support plate 3, the disinfection box 41 is filled with disinfectant, the input end of the liquid pump 42 is connected to the disinfection box 41 through the liquid disinfection pipe 43, the output end of the liquid pump 42 is connected to the liquid transfer disinfection pipe 44, the end of the liquid transfer disinfection pipe 44 passes through the inner top wall of the box body 1, the liquid separation disinfection pipe 45 is located on the inner upper part of the box body 1 and is connected to the end of the liquid transfer disinfection pipe 44, and a number of spray heads 46 are provided on the liquid separation disinfection pipe 45; the upper surface of the box body 1 is provided with a volatilization mechanism 5.

[0021] In this application, the liquid pump 42 is electrically connected to an external power supply. The disinfectant in the disinfection box 41 is extracted by the liquid pump 42, and pressure is applied to the liquid. The pressurized disinfectant is forcibly transported to the liquid separation disinfection pipe 45 through the liquid transfer disinfection pipe 44, and then transmitted to each spray head 46 through the liquid separation disinfection pipe 45, and finally sprayed out by the spray head 46 for disinfection treatment.

[0022] See Figure 2The number of the spray heads 46 is six, wherein the liquid spraying ports of three of the spray heads 46 are oriented in opposite directions to the liquid spraying ports of the other three spray heads 46, and the spray heads 46 are evenly distributed horizontally along the length direction of the liquid separation and disinfection tube 45, thereby spraying evenly on the front and back sides of the interior of the box 1 to achieve a uniform disinfection effect.

[0023] See Figure 3 The volatilization mechanism 5 includes a blower 51, a heating box 52, an air transmission duct 53, a groove 54, a heating element 55 and an exhaust assembly 56; the blower 51 is located on the upper surface of the box body 1, and the heating box 52 is located on the rear surface of the box body 1. The output end of the blower 51 is connected to the heating box 52 through the air transmission duct 53. The inner wall of the heating box 52 is provided with a groove 54, and the heating element 55 is embedded in the groove 54; an exhaust assembly 56 is provided under the heating box 52, and the blower 51 is electrically connected to the external power supply. When the blower 51 is started, the inhaled air is transported to the heating box 52 through the air transmission duct 53, and the air is heated by the heating element 55 in the heating box 52 and converted into hot air.

[0024] See Figure 3 The heating element 55 is an electric heating tube, which is electrically connected to an external power source to heat the air.

[0025] See Figure 3 The exhaust component 56 includes an exhaust fan 561, an exhaust duct 562 and an air outlet duct 563; the exhaust fan 561 is installed on the rear surface of the box body 1 and is located below the heating box 52. The input end of the exhaust fan 561 is connected to the heating box 52 through the exhaust duct 562, and the output end of the exhaust fan 561 is connected to the air outlet duct 563. The end of the air outlet duct 563 passes through the inner bottom wall of the box body 1. The exhaust fan 561 extracts the hot air in the heating box 52 through the exhaust duct 562, and transports the hot air to the air outlet 6 through the air outlet duct 563, so that the hot air is blown out from the air outlet 6, thereby indirectly heating the residual disinfectant in the box body 1.

[0026] See Figure 3 The inner bottom wall of the box body 1 is provided with an air outlet 6 , and the air outlet 6 is connected to the end of the air outlet duct 563 .

[0027] See Figure 4 The inner side wall of the box body 1 is symmetrically provided with mounting blocks 7, and the mounting blocks 7 are horizontally distributed along the length direction of the box body 1. The side walls of the mounting blocks 7 are each provided with a convex groove 71, and the convex groove 71 is horizontally distributed along the length direction of the mounting blocks 7.

[0028] See Figure 5The left and right sides of the placement plate 2 are provided with convex blocks 8 adapted to the convex groove 71. The placement plate 2 is inserted into the convex groove 71 through the convex blocks 8 and is slidably connected with the mounting block 7, which facilitates the installation and disassembly of the placement plate 2 and is simple and convenient to operate.

[0029] See Figure 1 The front surface of the box body 1 is hinged with a box door 9, which is a tempered glass door with a heated anti-condensation layer. The heating layer maintains the glass surface temperature higher than the dew point in the box, completely preventing the observation window from fogging in low temperature or high humidity environments, and ensuring real-time visibility of the culture status.

[0030] Working process of the present invention: In the working process of the incubator capable of automatic disinfection of the present invention, when the box body 1 needs to be disinfected, the placement plate 2 is slid out from the convex grooves 71 on both sides, and then the disinfectant in the disinfection box 41 is extracted by the liquid extraction pump 42, and pressure is applied to the liquid. The pressurized disinfectant is forcibly transported to the liquid separation disinfection pipe 45 through the liquid transmission disinfection pipe 44, and then transmitted to each spray head 46 through the liquid separation disinfection pipe 45. When the pressurized disinfectant enters the internal cavity of the spray head 46, the pressurized liquid is forced to pass through the multiple fine spray holes at the end of the nozzle. When the liquid flows out of the small holes, due to the surface tension and the friction and shearing effect of the high-speed jet and the surrounding air, the jet becomes unstable and breaks into droplets, so that the disinfectant is sprayed from the nozzle of the spray head 46 in the form of a mist composed of a large number of tiny droplets, forming a mist. The spray field with a wider diffusion range and more uniform coverage allows the atomized particles to penetrate hidden areas such as gaps and corners in the box, achieving disinfection without dead angles. When the box 1 is disinfected, some disinfectant remains inside. If the residual disinfectant is not volatilized in time, it will easily affect the subsequent culture effect of the incubator. When the blower 51 is started, the inhaled air is transported to the heating box 52 through the air transmission duct 53. The air is heated by the heating element 55 in the heating box 52 and converted into hot air. At this time, the exhaust fan 561 draws out the hot air in the heating box 52 through the exhaust duct 562, and transports the hot air to the air outlet 6 through the air outlet duct 563, so that the hot air is blown out from the air outlet 6, thereby indirectly heating the residual disinfectant in the box 1, thereby increasing the kinetic energy of the liquid molecules to accelerate volatilization.

[0031] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices. Therefore, the control method and wiring layout are no longer explained in detail in the present invention.

[0032] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
