DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a ventilation structure for medical engineering, comprising a wall 1, a fixed column 2 is fixed on the left side of the wall 1, a ventilation assembly 200 for ventilation is installed on the left side of the wall 1, and a filter assembly 300 for purifying the outside air is installed on the left end of the fixed column 2;

[0024] Through the coordinated use of the wall 1, the fixed column 2, the ventilation component 200 and the filter component 300, in actual use, the filter used to intercept impurities can be conveniently and effectively cleaned, and the activated carbon used to filter gas odors can be conveniently and effectively replaced, thereby avoiding the situation where the ventilation efficiency decreases with the increase in use time, ensuring that the expected air purification effect can be achieved, and the operation is also relatively simple, thereby improving the practicality of the ventilation structure of medical engineering.

[0025] In this embodiment, the ventilation assembly 200 is a structure for achieving ventilation.

[0026] like Figure 1 As shown, the ventilation assembly 200 includes two fixed rods 201 fixed to the left side of the wall 1, a fan 202 is fixed between the ends of the two fixed rods 201 away from the wall 1, an air inlet pipe 206 is fixed to the air inlet end of the fan 202, an air outlet pipe 203 is fixed to the air outlet end of the fan 202, an air outlet tube 204 is fixed to the side of the air outlet tube 203 away from the fan 202, a first filter screen 205 is fixed inside the air outlet tube 204, and the first filter screen 205 is used to prevent other large objects from entering the air outlet tube 204 and the air outlet pipe 203 and causing blockage. There is no need to filter the air, so there is no need to disassemble and clean them.

[0027] It should be noted that the side of the air outlet pipe 203 away from the fan 202 penetrates the wall 1 and extends to the right side of the wall 1 to be fixed to the air outlet pipe 204, ensuring that the air outlet pipe 203 can transport the clean air to the air outlet pipe 204.

[0028] In this embodiment, the filter assembly 300 is a structure for purifying the external air.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the filter assembly 300 includes a processing box 301 fixed to the left side of the fixed column 2, two through holes 302 are provided on the left side of the processing box 301, two baffles 303 are hinged on the left side of the processing box 301 through hinges, a first filter layer 304 is slidably connected inside the processing box 301, a second filter layer 305 is slidably connected inside the processing box 301, two annular grooves 306 are provided inside the processing box 301, an air inlet cylinder 307 is fixed to the bottom of the processing box 301, a fixed cylinder 308 is internally threadedly connected to the air inlet cylinder 307, and a second filter screen 309 is fixedly connected to the inside of the fixed cylinder 308.

[0030] It should be noted that the side of the air inlet pipe 206 away from the fan 202 passes through the processing box 301 and extends to the inside of the processing box 301, ensuring that the air after cleansing treatment in the processing box 301 can enter the fan 202 through the air inlet pipe 206.

[0031] In addition, handles are fixed on the left sides of the first filter layer 304 and the second filter layer 305, which facilitate the first filter layer 304 and the second filter layer 305 to be removed from the processing box 301 through the handles. The height of the through hole 302 is respectively greater than the height of the first filter layer 304 and the second filter layer 305, ensuring that the first filter layer 304 and the second filter layer 305 can effectively pass through the through hole 302.

[0032] In addition, the first filter layer 304 and the second filter layer 305 are respectively slidably connected to the inside of the two annular grooves 306, ensuring that the first filter layer 304 and the second filter layer 305 can completely and effectively process the air passing through the processing box 301. The first filter layer 304 is a bamboo charcoal layer, and the second filter layer 305 is an activated carbon layer, which can effectively absorb odors and toxic gases in the outside air.

[0033] At the same time, the width of the baffle 303 is equal to the width of the through hole 302, and the height of the baffle 303 is equal to the height of the through hole 302, ensuring that the baffle 303 can close the through hole 302 during use. A fixing ring is fixed at the bottom of the second filter screen 309, which is convenient for driving the second filter screen 309 to rotate through the fixing ring.

[0034] The working principle of the above embodiment is:

[0035] During use, the fan 202 is turned on to allow the outside air to enter the processing box 301 through the air inlet cylinder 307. At this time, the outside air first passes through the second filter 309 to block the large particles contained in the outside air, and then the air passes through the first filter layer 304 and the second filter layer 305 in turn to absorb the odor and harmful gases contained in the outside air, thereby completing the purification of the outside air, and then is discharged to the department inside the hospital through the air inlet pipe 206, the air outlet pipe 203 and the air outlet cylinder 204. After using it for a period of time, the second filter 309 is rotated by the pull ring, thereby driving the fixed cylinder 308 to rotate, so that the fixed cylinder 308 can be separated from the air inlet cylinder 307, so that the second filter 309 can be taken out for cleaning, and then the baffle 303 is opened, and the first filter layer 304 and the second filter layer 305 are respectively pulled out of the processing box 301 by the handle, so as to facilitate their replacement, which is relatively simple to operate, thereby ensuring that the expected effect of purifying the outside air can be achieved.

[0036] Compared with the prior art, the ventilation structure for medical engineering, through the coordinated use of the wall 1, the fixed column 2, the ventilation component 200 and the filter component 300, can conveniently and effectively clean the filter for intercepting impurities during actual use, and can conveniently and effectively replace the activated carbon for filtering gas odor, thereby avoiding the situation where the ventilation efficiency decreases with the increase in use time, ensuring that the expected air purification effect can be achieved, and the operation is also relatively simple, thereby improving the practicability of the ventilation structure of medical engineering and solving the problem of low practicability of the existing ventilation structure of medical engineering.

[0037] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of an external power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0038] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
