[0002] In today's society, people have higher and higher requirements for their living environment. They are not only concerned about the outdoor environment, but also have higher and higher requirements for the quality of indoor air.

[0003] At present, the most basic way for people to convert indoor air with outdoor air is ventilation, that is, to introduce outdoor clean air into the room through natural ventilation or mechanical ventilation to replace the polluted air in the room. This method is simple and easy, but in the case of poor outdoor air quality, ventilation cannot play a good purification effect, and an indoor air circulation device is needed.

[0004] Especially for indoor environments such as hospital emergency rooms, the air purification requirements are higher, so the indoor air circulation equipment used also needs to have a sterilization effect to reduce the indoor bacterial content, so the air entering the room needs to pass through disinfectant.

[0066] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0067] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0069] While disinfecting, disinfectant also absorbs dust and impurities in the air. As a result, the actual consumption of disinfectant is far greater than the amount consumed for sterilization, and the application cost of disinfectant is relatively high.

[0070] In view of this, the present invention provides a disinfection and ventilation device for a sterile emergency cabin, comprising a cleaning shell 100, a transfer pump 200 and a filter assembly 300; the cleaning shell 100 is provided with an air inlet, an air outlet, a liquid inlet and a liquid outlet; the inlet of the transfer pump 200 is connected to the filter assembly 300, and the outlet is connected to the liquid inlet; the filter assembly 300 is also connected to the liquid outlet.

[0071] In the disinfection ventilation device of the sterile emergency cabin, disinfectant is contained in the clean shell 100. When air is introduced into the clean shell 100 from the air inlet, the air passes through the disinfectant to achieve sterilization and disinfection, and then is discharged through the air outlet; when the transfer pump 200 is working, the disinfectant is drawn out from the liquid outlet, filtered by the filter assembly 300, and then returned to the clean shell 100 from the liquid inlet.

[0072] It can be seen that compared with the existing technology, the disinfection and ventilation device of the sterile first aid cabin can not only sterilize and disinfect the air, but also filter the disinfectant, thereby increasing the utilization rate of the disinfectant and reducing the application cost of the disinfectant.

[0073] The following combination Figures 1 to 8 The structure and shape of the disinfection ventilation device of the sterile first aid cabin provided in this embodiment are described in detail:

[0074] In this embodiment, reference Figures 1 to 3 The disinfection ventilation device of the sterile emergency cabin also includes a blower 1100, an exhaust pump 1300, a bottom box shell 400 and a reflux duct 500; the air inlet is at one end of the clean shell 100, and the blower 1100 is connected to the air inlet; the air outlet is at the other end of the clean shell 100, and the exhaust pump 1300 is connected to the air outlet through an exhaust pipe 1200; there are two liquid outlets, which are symmetrically distributed on the side wall of the clean shell 100 about the axis of the clean shell 100; there are two reflux ducts 500, one end of the two reflux ducts 500 is connected to the two liquid outlets respectively, and the other end is connected to the bottom box shell 400; the filter assembly 300 corresponds to the reflux duct 500 one by one, and its filter part is in the bottom box shell 400, and the transfer pump 200 is fixed in the bottom box shell 400 and is located between the two filter parts.

[0075] When purifying the air, the blower 1100 and the vacuum pump 1300 are started, the former blows the air into the cleaning shell 100 from the air inlet, and after being disinfected and sterilized by the disinfectant, assisted by the suction of the vacuum pump 1300, the air is discharged in sequence through the air outlet, the exhaust pipe 1200 and the vacuum pump 1300, and the purification is completed; after using for a period of time, the transfer pump 200 is started, and the transfer pump 200 draws the disinfectant through the reflux pipe 500 to the bottom box shell 400. After being filtered by the filter part, the disinfectant returns to the cleaning shell 100, and the filtration is completed, and the air can be purified again.

[0076] By adopting the above design, the disinfectant can be circulated and filtered, thereby greatly improving the utilization rate of the disinfectant and reducing the cost of using the disinfectant.

[0077] Regarding the filter assembly 300, specifically:

[0078] refer to Figure 3 and Figure 4 , the end of the bottom box shell 400 is open; the filter assembly 300 includes a sealing plate 310, a traction rod 320 and a filter plate 330; the sealing plate 310 blocks the open end of the bottom box shell 400 and is detachably connected to the bottom box shell 400. Optionally, the sealing plate 310 is snap-fitted to the bottom box shell 400; the traction rod 320 is passed through the sealing plate 310, one end of which is threadedly connected to an external sleeve 340 outside the bottom box shell 400, and the other end is fixedly connected to the filter plate 330 inside the bottom box shell 400; the connection point between the reflux pipe 500 and the bottom box shell 400 is located between the sealing plate 310 and the filter plate 330, the filter plate 330 is the filter part, and its outer side surface is in contact with the inner wall of the bottom box shell 400.

[0079] When filtering the disinfectant, the disinfectant enters the bottom housing 400 through the reflux pipe 500 by the suction force of the transfer pump 200, then flows through the filter plate 330, and returns to the cleaning housing 100 after passing through the transfer pump 200, and repeats this process until the filtering is completed. When the filter plate 330 needs to be replaced after working for a long time, the sealing plate 310 is disconnected from the bottom housing 400, and then the filter assembly 300 is pulled out of the bottom housing 400 as a whole, the external sleeve 340 is screwed, the traction rod 320 is removed from the sealing plate 310, and the filter plate 330 is replaced.

[0080] For further reference, Figure 4 The filter assembly 300 also includes a pressure-sensitive inner plate 350 and a sliding pressure rod 360 ; the pressure-sensitive inner plate 350 is fixed in the sealing plate 310 ; the sliding pressure rod 360 is fixed to the pressure-sensitive inner plate 350 , and one side of the sliding pressure rod passes through the sealing plate 310 and faces the filter plate 330 .

[0081] With the above design, when filtering the disinfectant, the transfer pump 200 not only draws the disinfectant but also applies a traction force to the sliding pressure rod 360 in a direction away from the pressure-sensitive inner plate 350. The suction and pressure force of the transfer pump 200 can be determined based on the traction force applied to the pressure-sensitive inner plate 350. In this way, it can be ensured that the suction force of the transfer pump 200 to adsorb the disinfectant meets the standard, so that the disinfectant can pass through the stacked filter plates 330 to achieve the filtering purpose.

[0082] When replacing the filter plate 330, in order to prevent the disinfectant in the reflux pipe 500 from leaking, Figure 3 As shown, a liquid separation switch 600 is provided at the connection point between the reflux pipe 500 and the bottom box shell 400. Specifically, the liquid separation switch 600:

[0083] refer to Figure 5 The liquid dispensing switch 600 includes a fixed block 610, a rolling ball 620 and a driving assembly 630; the fixed block 610 is fixed in the reflux pipe 500; the rolling ball 620 is movably arranged in the fixed block 610, and a through channel is provided on the rolling ball 620. In the initial state, the rolling ball 620 is connected to the fixed block 610. Figure 3 As shown, the through channel is vertical, connecting the reflux pipe 500 and the bottom box shell 400; the driving component 630 is transmission-connected with the rolling ball 620 to drive the rolling ball 620 to rotate around its own axis perpendicular to the through channel, so that the two ends of the through channel are both in the fixed block 610, or are respectively connected to the reflux pipe 500 and the bottom box shell 400.

[0084] Specifically, two groups of driving components 630 are provided, and the two groups of driving components 630 are symmetrically distributed about the center of the rolling ball 620; the driving component 630 includes a transmission rod 631 and a rotation driver 632; one end of the transmission rod 631 is fixed to the rolling ball 620, and the other end is fixed to the output part of the rotation driver 632; optionally, the rotation driver 632 uses a motor.

[0085] When the suction pressure of the transfer pump 200 is less than the preset value, it indicates that the filter plate 330 needs to be replaced. During replacement, the motor is started, and the motor drives the rolling ball 620 to rotate 90° through the transmission rod 631, so that the through-channel becomes horizontal. The two ports of the through-channel are blocked by the fixed block 610, and the connection between the reflux pipe 500 and the bottom box shell 400 is disconnected, thereby achieving the effect of blocking the reflux pipe 500.

[0086] In this embodiment, reference Figure 2The disinfection ventilation device of the sterile emergency cabin also includes a drain assembly 700, a reflux assembly 900 and an air intake assembly 800, which are respectively arranged at the liquid outlet, the liquid inlet and the air inlet; under the air purification condition, the air intake assembly 800 is in an open state, allowing air to enter the clean shell 100, and the drain assembly 700 and the reflux assembly 900 are both in a closed state to prevent air from leaking through the liquid outlet and the liquid inlet, thereby ensuring the air tightness of the clean shell 100; under the condition of filtering disinfectant, the air intake assembly 800 is in a closed state to prevent the disinfectant inside the clean shell 100 from leaking, and the drain assembly 700 and the reflux assembly 900 are both in an open state to establish a circulation path.

[0087] Regarding the drain assembly 700, specifically:

[0088] refer to Figure 2 and Figure 6 The drain assembly 700 includes a drain cylinder 710, a connecting pipe 720 and an elastic member 730; the drain cylinder 710 is fixed in the cleaning shell 100, and its end is connected to the liquid outlet, and a plurality of water inlet grooves are provided on its side wall, and the plurality of water inlet grooves are spaced around the axis of the drain cylinder 710; the water inlet groove connects the inner cavity of the drain cylinder 710 with the inner cavity of the cleaning shell 100; the connecting pipe 720 is coaxially arranged with the drain cylinder 710 and inserted into the drain cylinder 710, and a baffle 721 for blocking itself is fixed at one end thereof, and optionally, the baffle 721 is an arc convex toward the direction of the reflux pipe 500; a plurality of liquid holes are provided on the baffle 721; the elastic member 730 is connected to the connecting pipe 720, so that the connecting pipe 720 has a tendency to slide into the drain cylinder 710 to block the water inlet groove.

[0089] Further, combined with Figure 6 As shown, both ends of the liquid discharge cylinder 710 are connected to the two liquid outlets respectively; two connecting pipes 720 are also provided, and are distributed with two baffles 721 away from each other; more preferably, the elastic member 730 adopts a tension spring, and both ends of the tension spring are connected to the two baffles 721 respectively.

[0090] In the initial state, the opposite ends of the two connecting tubes 720 are butt-jointed, and the side walls of the two connecting tubes 720 cooperate to block multiple water inlet grooves; when the transfer pump 200 is working, under the action of suction and pressure, the two connecting tubes 720 are pulled apart to release the blockage of the water inlet groove, and at the same time the tension spring is stretched, at which time the disinfectant can enter the discharge cylinder 710 through the water inlet groove, and then enter the bottom box shell 400 through the inner cavity of the connecting tube 720, the liquid hole, the reflux pipe 500, and the through channel in turn for filtration; when the transfer pump 200 stops, under the action of the restoring force of the tension spring, the two connecting tubes 720 are butt-jointed again to block the water inlet groove.

[0091] It should be added here that, preferably, a limiting structure is provided between the drain cylinder 710 and the connecting pipe 720. After the two connecting pipes 720 completely release the blockage of the water inlet tank, the connecting pipe 720 moves into place under the action of the limiting structure, and the tension spring is no longer stretched. Such a design can prevent the connecting pipe 720 from entering the reflux pipe 500 under the action of the pumping pressure. Regarding the limiting structure, it can be designed as a limiting step, which is a conventional technical means and will not be elaborated in detail.

[0092] Regarding the reflux assembly 900, specifically:

[0093] refer to Figure 2 and Figure 3 The reflux assembly 900 includes a plurality of groups of guide cylinders 910 and liquid inlet pipes 920; in each group, the top end of the guide cylinder 910 is connected to the liquid inlet, and the bottom end is connected to the outlet of the transfer pump 200; the liquid inlet pipe 920 is inserted into the guide cylinder 910, with its bottom end open and the top end closed to seal the guide cylinder 910; a plurality of drainage grooves are provided on the side wall of the liquid inlet pipe 920, and the plurality of drainage grooves are spaced apart around the axis of the liquid inlet pipe 920 and extend from the open end to the closed end.

[0094] As mentioned above, a docking top cover 1000 is fixed on the side wall of the cleaning shell 100; a limiting column 1010 is protruded from the docking top cover 1000, and the limiting column 1010 corresponds to the liquid inlet pipe 920 one by one, and the bottom end of the limiting column 1010 is opposite to the closed end.

[0095] During the disinfectant circulation filtration process, Figure 1 and Figure 2 As shown, the transfer pump 200 discharges the filtered disinfectant into the liquid inlet pipe 920 through its outlet. Under the push of the disinfectant, the liquid inlet pipe 920 slides upward, and the drainage groove slides out of the guide cylinder 910, connecting the inner cavity of the liquid inlet pipe 920 with the inner cavity of the cleaning shell 100, so that the disinfectant enters the cleaning shell 100; when the liquid inlet pipe 920 slides to contact with the limit column 1010, it slides into place, and at this time, the bottom end of the liquid inlet pipe 920 is still in the guide cylinder 910; after the transfer pump 200 stops working, under the action of its own gravity, the liquid inlet pipe 920 returns to the guide cylinder 910, and the guide cylinder 910 is blocked again to prevent the disinfectant in the cleaning shell 100 from leaking from the liquid inlet.

[0096] Regarding the air intake assembly 800, specifically:

[0097] refer to Figure 7 and Figure 8The air intake assembly 800 includes an air intake pipe 810, an air intake cylinder 820 and a compression sleeve 830; one end of the air intake pipe 810 is connected to the air inlet, and the other end is connected to the blower 1100; a plurality of ventilation holes are provided on the side wall of the air intake cylinder 820, one end of the air intake cylinder 820 is open and inserted into the air intake pipe 810, and the other end is closed, passes through the air intake pipe 810, and is located in the cleaning shell 100; the compression sleeve 830 is in the air intake pipe 810, and is sleeved on the air intake cylinder 820, and one end of the compression sleeve is connected to one end of the air intake cylinder 820 in the air intake pipe 810, and the other end is connected to the air intake pipe 810.

[0098] In the initial state, Figure 8 For example, the ventilation hole is completely inside the air inlet pipe 810, and the air inlet cylinder 820 is not connected to the inner cavity of the cleaning shell 100; when the blower 1100 pressurizes air into the air inlet pipe 810, the air pressure will push the air inlet cylinder 820 toward the inside of the cleaning shell 100, compressing the compression sleeve 830, so that the ventilation hole moves into the cleaning shell 100. At this time, the air pressure is much greater than the hydraulic pressure of the internal disinfectant, and air will enter the cleaning shell 100 through the ventilation hole; when the blower 1100 stops working, under the action of the restoring force of the compression sleeve 830, the air inlet cylinder 820 is reset, and the connection between its inner cavity and the inner cavity of the cleaning shell 100 is disconnected.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
