Secondly the pillow 6 can be dismantled and set up on pillowcase 2, and thereby pillow 6 is made for flexible material and is used for providing comfort level for patient, and detachable structure can adopt connection methods such as button or zip fastener simultaneously. An opening three 61 is opened on the pillow 6 corresponding to the through hole 11, and an auxiliary part 62 is extended downward from the pillow 6 inside the opening three 61, and the auxiliary part 62 abuts against the inner wall of the through hole 11.

Thus, in actual use, the comfort of the patient can be improved by the arrangement of the pillow 6, and the discomfort of the patient caused by the edge of the through-hole 11 can be avoided by the arrangement of the auxiliary portion 62. And the cambered surface 64 is formed at the connecting part between the inner wall of the three openings 61 and the peripheral side of the three openings 61, so that the right angle is converted into the cambered surface, and the discomfort of the patient caused by the edge is avoided.

As shown in fig. 2, the replacing component includes a blower 41, one side of the pillow core 1 is provided with a first air inlet 121 communicated with the second opening, the inner wall of the through hole 11 is provided with a second air inlet 111 and a first air outlet 112, the blower 41 is respectively communicated with the first air inlet 121, the second air inlet 111 and the first air outlet 112, and air in the through hole 11 is drawn out by the blower 41.

Therefore in the in-service use process, inhale and transport external air to through-hole 11 in through-hole through fan 41 to change the air in the through-hole 11, and then avoid appearing breeding the condition of microorganism such as fungi or bacterium, and thereby can also let the patient of lying prostrate can breathe for a long time and lie prostrate for a long time and not influenced.

Therefore in the in-service use process, fan 41 is air intake 121 earlier and inhales the air to carry inspiratory air to clarifier 45 through fan 41 and purify, transport again to in the through-hole 11, thereby change the air in the through-hole 11, and then avoid appearing breeding the condition of microorganism such as fungi or bacterium, and thereby can also let the patient of lying prostrate breathe for a long time and can lie prostrate for a long time and be not influenced.

This is because if air is directly sucked from the air outlet 112, a vacuum state may occur in the through hole 11 without air, which may cause damage to the human body.

Then when fan 41 transported fresh air to through-hole 11 in, can let fan 41 inhale the air from air outlet 112 this moment to transport inspiratory air to clarifier 45 through fan 41 and purify, transport again to in the through-hole 11, thereby realize the cyclic utilization of air in the through-hole 11, thereby avoid the direct discharge of not good air to cause the influence to the environment of sick room.

When the air recycling is realized, the fan 41 does not suck air from the first air inlet 12 any more, so that the condition that the air pressure in the through hole 11 is overlarge is avoided.

The operation of the valve 43 can be controlled by various structures, preferably by installing an air pressure sensor in the through hole 11 and matching the circuit board 8, when the air pressure sensor detects that the air pressure in the through hole 11 is increased, that is, the fan 41 has transported fresh air into the through hole 11, the fan 41 can suck air from the air outlet 112, and when the air pressure in the through hole 11 reaches a certain value, the fan 41 can not suck air from the air inlet 121 any more.

And a button 193 is provided at the exposed side of the pillow core 1 to drive the blower 41 to operate.

Therefore, in practical use, when the first electromagnetic driving source 435 is powered on, the first valve rod 433 moves and is communicated with the first air inlet 121 and the fan 41, and when the second electromagnetic driving source 436 is powered on, the second valve rod 434 moves and is communicated with the first air inlet 112 and the fan 41.

As shown in fig. 7, the structure of the purifier 45 is: firstly, the purifier 45 comprises a shell 451, an inlet 452 and an outlet 453 are respectively arranged on two sides of the shell 451, a filter plate 454 is vertically arranged between the inlet 452 and the outlet 453 of the shell 451, a plurality of positive plates 455 and negative plates 456 are horizontally arranged between the filter plate 454 and the outlet 453, and the positive plates 455 and the negative plates 456 are staggered.

Therefore, in actual use, air enters from the inlet 452 and flows through the filter plate 454 to be filtered, passes between the positive plate 455 and the negative plate 456 to be purified, and then exits from the outlet 453.

Wherein, a high-voltage electrostatic field is arranged between the positive plate 455 and the negative plate 456, and when gas enters, the gas is degraded, purified and dedusted under the action of the high-voltage electrostatic field. While the positive and negative electrode plates 455 and 456 may be provided with a plurality of serrations to increase a contact area with air.

And the filter 454 can be a plurality of filter plates, and is divided into an activated carbon filter plate and an ozone removing filter plate, thereby better evolving the air.

As shown in fig. 2, fig. 3 and fig. 8, mounting grooves 15 are formed in the top of the pillow core 1 at two sides of the through hole 11, a movable limiting block 16 is arranged in each mounting groove 15, and the pillowcase 2 and the pillow cushion 6 are respectively provided with four openings 25 and five openings 63 corresponding to the limiting blocks 16.

Therefore, in the actual use process, the movement of the head of the patient is limited through the arrangement of the limiting block 16, and the situation that the movement of the head affects the wound is avoided.

Wherein the moving structure of the limiting block 16 is: firstly, the bottom of the limiting block 16 is provided with a guide plate 161, the guide plate is provided with a guide groove, the guide groove is internally provided with a first positioning point 163 and a second positioning point 164, the bottom of the mounting groove 15 is provided with a rotatable limiting rod 17, the limiting rod 17 is provided with a convex block 171, and a spring 18 is arranged between the bottom of the limiting block 16 and the bottom of the mounting groove 15.

Therefore, in actual use, when the stopper 16 is located in the mounting groove 15, the protrusion 171 is located at the first positioning point 163, and the spring 18 is in a pressed state, by pressing the stopper 16, the protrusion 171 leaves the first positioning point 163, so that the stopper 16 moves under the urging of the spring 18 and is exposed from the opening five 63, and the protrusion 171 moves along the guide groove to the second positioning point 164.

Here, pressing the stopper 16 is released by pressing a little bit, i.e. a force is applied to the stopper 16, and the force can make the protrusion 171 leave the first positioning point 163.

When the pushed-out limit block 16 needs to be reset, the limit block 16 can be pressed inwards until the protrusion 171 leaves the second positioning point 164 and moves to the first positioning point 163 along the guide groove, and then the hand is taken away, at this time, the limit block 16 is already positioned in the mounting groove 15, and the protrusion 171 is positioned in the first positioning point 163, so that the limit block 16 is prevented from coming out.

As shown in fig. 8, the guide groove is a closed loop, and a first moving rail 166 and a second moving rail 167 are disposed between the first positioning point 163 and the second positioning point 164, wherein the depth of the first moving rail 166 at the first positioning point 163 is deeper than the depth of the second moving rail 167 at the first positioning point 163, and a first limit protrusion 168 is disposed between the first moving rail 166 and the first positioning point 163.

Therefore, in the actual use process, the movement of the projection 171 is limited by the different depths and the first limiting protrusion 168, and further, when the limiting block 16 is not pressed and is placed in the installation groove 15, the projection 171 can be ensured not to move in the first moving rail 166 or the second moving rail 167.

When the stopper 16 is pressed, the protrusion 171 moves along the guide groove, and then passes by the first stopper protrusion 168 and leaves the first positioning point 163 to enter the first moving rail 166. The different depths are provided to ensure that the projection 171 leaves the first positioning point 163 and then enters the first moving track 166, not the second moving track 167.

Meanwhile, the bottom of the second moving rail 167 is an inclined surface, and a second limit protrusion 169 is arranged between the first moving rail 166 and the second positioning point 164.

Therefore, in the actual use process, the movement of the protrusion 171 is limited by the inclined surface and the second limiting protrusion 169, and when the limiting block 16 is not pressed and is in the pushed-out state, the protrusion 171 cannot move in the first moving rail 166 or the second moving rail 167.

When the stopper 16 is pressed and pushed out, the protrusion 171 moves along the first moving track 166 and bypasses the second stopper protrusion 169 along the guide groove to enter the second positioning point 164. Therefore, when the limit block 16 is pressed again to reset the limit block 16, that is, the limit block 16 is placed back into the mounting groove 15, the second limit protrusion 169 is used to prevent the protrusion 171 from entering the first moving track 166 when leaving the second locating point 164, and ensure that the protrusion 171 enters the second moving track 167 instead of the first moving track 166 when leaving the second locating point 164.

As shown in fig. 2, the stopper 16 is provided with a pressing plate 165 on one side of the guide plate 161, and the stopper rod 17 is located between the pressing plate 165 and the guide plate 161, so as to prevent the stopper rod 17 from tilting and separating from the guide groove.

Therefore, in the actual use process, the limiting rod 17 is positioned between the pressing plate 165 and the guide plate 161, so that the pressing plate 165 and the guide plate 161 limit the limiting rod 17, and the situation that the limiting rod 17 tilts and is separated from the guide groove is avoided.

The mounting structure of the pressing plate 165 is: first, the stopper 16 is provided with a clamping groove, and one end of the pressing plate 165 is clamped in the clamping groove.

Simultaneously, the mounting structure of the limiting rod 17 is as follows: first, the mounting portion 151 is disposed at the bottom of the mounting groove 15, and the mounting portion 151 is opened with a mounting hole, and one side of the mounting hole is opened with a sixth opening.

And the end of the limit rod 17 connected with the bottom of the mounting groove 15 is provided with a connecting rod 172, and the connecting rod 172 is provided with a limit bulge 173. Thus, when being installed, the connecting rod 172 passes through the opening six and is located in the mounting hole, the limit block 172 abuts against the mounting portion 151, so that the connection of the limit rod 172 and the mounting groove 15 is realized, and the abutment of the limit block 172 against the mounting portion 151 can be used for preventing the connecting rod 172 from being detached from the mounting portion 151.

As shown in fig. 2, 4 and 5, two sides of the pillow case 2 are both provided with a second opening, wherein one side is provided with a first air inlet 12, the other side is provided with a first through hole 13, and the inner wall of the through hole 11 is hinged with a cover 14 which can be turned down.

Meanwhile, the cover 14 is provided with a second through hole 141. Therefore, in the actual use process, when a patient lies on the sickbed in a bent manner, the breathing tube can sequentially penetrate through the first perforation hole 13 and the second perforation hole 141 and then is connected with the breathing mask worn by the patient, and therefore when the patient needs to breathe through the breathing mask and also lies on the bent manner, the breathing mask can be achieved through the structure.

Wherein the cover 14 is arranged for facilitating the breathing tube to pass through the first tube penetrating hole 13 and the second tube penetrating hole 141.

As shown in fig. 2, the pillow 6 is provided with a pocket 65 on the inner wall on one side of the opening three 61, and the pillow 6 is provided with a button on the top on the other side of the opening three 61, and the air-permeable net 66 is housed in the pocket 65, and the air-permeable net 66 is taken out from the pocket 65, and the air-permeable net 66 is fitted with the button to cover the opening three 61.

Therefore, in the actual use process, the ventilating net 24 is taken out of the pocket 23, and the ventilating net 24 is matched with the button so as to cover the ventilating net 24 on the opening I21, so that the ventilating net can be taken out when needed and can be arranged when not needed, and compared with the situation that the ventilating net cannot be arranged, the ventilating net can avoid the situation of forgetting or losing.

The reason is that the novel portable multifunctional desk is not built-in, so that the novel multifunctional desk can be taken out when needed and sometimes forgotten when being busy, and can be lost when not used and is not noticed when being taken out and placed, and the novel multifunctional desk can avoid the situations through the built-in structure.
