In order to achieve the purpose, the invention adopts the following technical scheme: an electric nasal cavity flusher comprises a liquid storage barrel, a piston barrel and a pressure barrel, wherein a liquid inlet pipe is connected between the liquid storage barrel and the piston barrel, a connecting pipe is connected between the piston barrel and the pressure barrel, a liquid outlet pipe is connected onto the pressure barrel, one end of the liquid outlet pipe, which is far away from the pressure barrel, is detachably connected with a flushing pipe, a first one-way valve enabling flushing liquid to flow into the piston barrel from the liquid storage barrel in one way is arranged on the liquid inlet pipe, a second one-way valve enabling the flushing liquid to flow into the pressure barrel from the piston barrel in one way is arranged on the connecting pipe, and a valve is arranged on the flushing pipe; the piston cylinder is connected with a first piston in a sliding mode, and an electric driving mechanism used for driving the first piston to slide in the piston cylinder in a reciprocating mode is arranged on the outer side of the piston cylinder.
The principle and the advantages of the scheme are as follows: the liquid storage barrel is used for containing flushing liquid. Electric drive mechanism is arranged in driving first piston reciprocating sliding in the piston cylinder, thereby make the continuous grow in space that is equipped with the flush fluid in the piston cylinder and diminish, when the space grow that is equipped with the flush fluid in the piston cylinder, produce the negative pressure in the piston cylinder, the flush fluid in the stock solution bucket enters into the piston cylinder through feed liquor pipe and first check valve, when the space that is equipped with the flush fluid in the piston cylinder diminishes, the flush fluid in the piston cylinder enters into the pressure cylinder through connecting pipe and second check valve, thereby realized supplementing the flush fluid for the pressure cylinder is automatic. The flush fluid reaches a certain amount of back in the pressure cylinder, has certain pressure in the pressure cylinder, opens the valve this moment, and the flush fluid in the pressure cylinder flows through the drain pipe under the effect of pressure in the pressure cylinder, then during the flush fluid of outflow enters into the nasal cavity through the flush tube, washes the nasal cavity. This scheme passes through the continuous reciprocating sliding of the first piston of electric drive mechanism drive, thereby realized that the piston cylinder is constantly from the stock solution bucket suction flush fluid, and supply the flush fluid to the pressure cylinder, realized replenishing in the pressure cylinder, the pressure of the flush fluid in the pressure cylinder in the outflow back pressure cylinder can reduce like this, after the pressure in the pressure cylinder reduces, new flush fluid in the piston cylinder supplies in the pressure cylinder, make the pressure in the pressure cylinder can resume, make the outflow that the flush fluid can last.
When adopting above-mentioned technical scheme, have following beneficial effect: 1. the nasal cavity irrigator has the advantages that the nasal cavity irrigator has automaticity and high efficiency in the using process, the medical staff is not needed to help when the nasal cavity irrigator is used, and a patient can irrigate the nasal cavity by opening the electric driving mechanism and the valve automatically.

3. The first piston in the piston cylinder can be for pouring into the flush fluid into intermittently in the pressure cylinder in the reciprocal slip, and when the piston cylinder inhaleed the flush fluid from the stock solution bucket, the piston cylinder can not pour into the flush fluid into the pressure cylinder, persists the flush fluid in the pressure cylinder this moment, and the flush fluid in the pressure cylinder flows out from the wash pipe under the pressure effect of pressure cylinder, and the flush fluid that flows out like this from the wash pipe is continuous, can not cut off because of the reciprocal slip of first piston.
4. Because the flushing pipe can be dismantled and connect on the drain pipe, the flushing pipe after the use can be dismantled from the drain pipe and disinfect to can carry out used repeatedly to the flushing pipe.

The top end of the liquid outlet pipe 17 is detachably connected with the flushing pipe 19, specifically, as shown in fig. 2, a first conical head 33 communicated with the top end of the liquid outlet pipe 17 is integrally formed on the top end of the liquid outlet pipe 17, the first conical head 33 is located above the clamping block 34, the top end of the first conical head 33 is a small end, a second conical head 32 communicated with the bottom end of the flushing pipe 19 is integrally formed on the bottom end of the flushing pipe 19, the bottom end of the second conical head 32 is a large end, and an opening is formed in the bottom of the second conical head 32, so that the second conical head 32 can be sleeved on the first conical head 33 along the arrow direction in fig. 2, and the detachable connection between the flushing pipe 19 and the liquid outlet pipe 17 is realized. Of course, it is easy to understand that, in order to make the connection between the first conical head 33 and the second conical head 32 more stable, corresponding annular protrusions may be provided on both the outer wall of the first conical head 33 and the inner wall of the second conical head 32, and the first conical head 33 and the second conical head 32 are connected more stably by the engagement of the annular protrusions. The liquid inlet pipe 6 is provided with a first one-way valve 5 which enables the flushing liquid to flow into the piston cylinder 11 from the liquid storage barrel 3 in one way, the connecting pipe is provided with a second one-way valve 7 which enables the flushing liquid to flow into the pressure cylinder 8 from the piston cylinder 11 in one way, and the flushing pipe 19 is provided with a valve 10. The flushing pipe 19 in this embodiment is a rubber pipe. The top end of the irrigation tube 19 is a tapered end.
In the present embodiment, a first piston 12 is vertically slidably connected in a piston cylinder 11, the bottom of the piston cylinder 11 is closed, the top of the piston cylinder 11 is provided with an opening, and an electric driving mechanism for driving the first piston 12 to slide in the piston cylinder 11 in a reciprocating manner is arranged outside the piston cylinder 11. The electric drive mechanism in this embodiment includes cylinder 15, and the welding has riser 14 on the base 1, and cylinder 15 passes through the fix with screw on riser 14, and cylinder 15 is located the top of piston barrel 11, has first piston rod 13 through the screw connection between cylinder 15 pole of cylinder 15 and first piston 12.
The specific implementation process is as follows: the washing liquid is filled into the liquid storage barrel 3 in advance, the air cylinder 15 is started, the air cylinder 15 vertically reciprocates, and the air cylinder 15 drives the first piston 12 to vertically reciprocate in the piston cylinder 11 through the first piston rod 13. When the first piston 12 moves upwards, negative pressure is generated in the piston cylinder 11, the piston cylinder 11 enables washing liquid in the liquid storage barrel 3 to enter the piston cylinder 11 through the liquid inlet pipe 6 and the first one-way valve 5, and when the first piston 12 moves downwards, the first piston 12 enables the washing liquid in the piston cylinder 11 to be pressed into the pressure cylinder 8 through the connecting pipe and the second one-way valve 7. By this means, a vertically reciprocating movement of the first piston 12 is achieved, whereby a constantly increasing flushing liquid volume is achieved in the pressure cylinder 8 and a pressure increase in the pressure cylinder 8 is achieved.
When rinsing the nasal cavity, sit on the chair, the face is towards collecting vessel 9, insert a nasal cavity with the toper end of wash pipe 19, open valve 10, the flush fluid in the pressure cylinder 8 flows into wash pipe 19 through drain pipe 17 automatically under the effect of pressure in the pressure cylinder 8, and flow into the nasal cavity from wash pipe 19, wash the nasal cavity, the liquid of washing flows out through another nasal cavity, because face is towards collecting vessel 9, so the waste liquid that flows out from another nasal cavity enters into collecting vessel 9, the collection to the waste liquid has been realized. After the nasal cavity is flushed, the flushing pipe 19 is pulled out of the nasal cavity and inserted into the other nasal cavity to flush the other nasal cavity. After the rinsing tube 19 is used, the rinsing tube 19 can be pulled out from the liquid outlet pipe 17, replaced with a new rinsing tube 19, and then the used rinsing tube 19 is sterilized to be reusable. It will be readily appreciated that, in order to moderate the pressure of the flushing liquid flowing out of the flushing pipe 19, the inner diameter of the flushing pipe 19 may be made larger than the inner diameter of the liquid outlet pipe 17, and the inner diameter of the flushing end at the top of the flushing pipe 19 may be made larger than the inner diameter of the bottom end of the flushing pipe 19, so that the flow rate of the flushing end of the flushing pipe 19 may be reduced under a certain flow rate, thereby avoiding discomfort to the nasal cavity due to an excessive flow rate. In addition, a pressure gauge can be externally connected to the pressure cylinder 8, and the pressure in the pressure cylinder 8 is controlled within a proper range by reading the pressure gauge, so that the pressure of the sprayed liquid is not too high to cause discomfort to the nasal cavity.
This embodiment is in the vertical removal in-process of first piston 12, and first piston 12 upwards moves the in-process, though piston cylinder 11 can not provide the flush fluid to in the pressure cylinder 8, but has a quantitative flush fluid in the pressure cylinder 8, and the flush fluid that exists can flow out under the effect of pressure cylinder 8 pressure in the pressure cylinder 8, can not make the flush fluid cutout for the flush fluid can last wash the nasal cavity. When the first piston 12 is then moved downward, the piston cylinder 11 presses the rinsing liquid into the pressure cylinder 8 again, and the pressure cylinder 8 is replenished with a new rinsing liquid. In the whole process, the patient can wash the nasal cavity by opening the air cylinder 15 and the valve 10 by himself, and the operation is simple and convenient. It is easy to understand that the flow rate of the flushing liquid flowing out can be controlled by controlling the opening degree of the valve 10, so as to avoid the liquid in the pressure cylinder 8 from being consumed too fast due to the overlarge flow rate; or the flow speed of the liquid is moderate by setting the sizes of the inner diameters of the flushing pipe 19 and the liquid outlet pipe 17 and the size of the pressure cylinder 8, so that the flushing liquid in the pressure cylinder 8 can be used for a period of time, and the liquid in the pressure cylinder 8 is prevented from being exhausted when the piston cylinder 11 does not supplement the liquid into the pressure cylinder 8 in time.
It is easy to understand that different numbers of liquid outlet pipes 17 can be communicated with the pressure cylinder 8 according to actual conditions so as to simultaneously wash the nasal cavities of different numbers of patients.
Example 2
As shown in fig. 3, the pressure cylinder 8 is closed at the bottom and open at the top. Vertical sealed sliding connection has second piston 22 in the pressure cylinder 8, has second piston rod 21 through screw fixed connection on the second piston 22, all is equipped with the tooth on the left surface of second piston rod 21 and the right flank of first piston rod 13, and the meshing has gear 20 between first piston rod 13 and the second piston rod 21, and gear 20 rotates through the pivot and connects on riser 14.
When the first piston rod 13 drives the first piston 12 to move upwards, the washing liquid in the pressure cylinder 8 is not replenished at this time, and the washing liquid in the pressure cylinder 8 is in an outflow state, and the amount of the washing liquid in the pressure cylinder 8 is gradually reduced. When the first piston rod 13 moves upwards, the second piston rod 21 is driven to move downwards through the gear 20, and the second piston rod 21 drives the second piston 22 to slide downwards in the pressure cylinder 8, so that the space in the pressure cylinder 8 is reduced, and thus, along with the reduction of the liquid amount in the pressure cylinder 8, the space in the pressure cylinder 8 is correspondingly reduced, the reduction of the pressure cylinder 8 due to the reduction of the flushing liquid in the pressure cylinder 8 and the unchanged space is avoided, and the pressure of the pressure cylinder 8 is in a stable state.
Similarly, when the first piston rod 13 drives the first piston 12 to move downwards, the piston cylinder 11 supplies new washing liquid to the pressure cylinder 8, and the washing liquid in the pressure cylinder 8 is increased. The first piston rod 13 drives the second piston rod 21 to move upwards through the gear 20, the second piston rod 21 drives the second piston 22 to move upwards in the pressure cylinder 8, and the space in the pressure cylinder 8 becomes larger, so that the space in the pressure cylinder 8 becomes larger correspondingly as the liquid amount in the pressure cylinder 8 becomes larger, thereby avoiding the pressure of the pressure cylinder 8 from increasing due to the fact that the flushing liquid becomes more as the space of the pressure cylinder 8 does not change, and being beneficial to the pressure of the pressure cylinder 8 being in a stable state. So through this embodiment, when supplementing the flush fluid or stopping supplementing the flush fluid in to pressure cylinder 8, the pressure in pressure cylinder 8 can be in relatively stable state, does benefit to the stable outflow of flush fluid, does benefit to the comfort level that improves the nasal cavity and washes.
