As shown in fig. 1-5, the present invention provides a device for administering a drug to the ear, nose and throat, which is not easy to be blocked, comprising a body 100, wherein the body 100 is provided with a drug canister and a drug spraying device for spraying a drug solution, which are all the prior art, and therefore, the detailed description thereof is omitted, and the detailed description thereof is omitted in the accompanying drawings.

The above described drug delivery device further comprises a nozzle 200, a slider 300, a first drive structure 400, a second drive structure 500 and a locking structure 600.

Wherein, the nozzle 200 is provided with a plurality of micro-jet holes 210, the head of the body 100 is provided with a sliding groove 110, and the nozzle 200 is slidably inserted in the sliding groove 110. Specifically, the nozzle 200 is slidable back and forth within the chute 110 between a first operating position and a second operating position.

The top side of the head of the body 100 is opened with a mounting cavity 120, and the mounting cavity 120 is communicated with the chute 110. The slider 300 is slidably installed in the installation cavity 120, and the side of the slider 300 facing the sliding chute 110 is provided with insertion rods 310 corresponding to the micro-injection holes 210 one to one. In particular, the nozzle 200 can be moved along the runner 110 from a first operating position to a second operating position, when the nozzle 200 is in the second operating position, the nozzle 200 corresponding to the slider 300. Preferably, the end of the plunger facing the nozzle is provided as a tip to facilitate unclogging.

The first drive structure 400 is adapted to drive the nozzle 200 in reciprocating linear motion between a first operating position and a second operating position. Specifically, when the nozzle 200 is in the first working position, the nozzle 200 corresponds to the medicine ejection channel 130 provided on the body 100, and when the nozzle 200 is in the first working position, the nozzle 200 corresponds to the slider 300. Thus, when the nozzle 200 is blocked, the nozzle is moved from the first working position to the second working position for dredging under the action of the first driving structure 400, and then is moved from the second working position to the first working position for use under the action of the first driving structure 400 after dredging is completed.

The second driving structure 500 is used for driving the slider 300 to perform reciprocating linear motion between the first working position and the second working position. Specifically, when in the first working position, the slider 300 is located at an end of the mounting cavity 120 away from the nozzle 200, and at this time, the plunger 310 cannot be inserted into the micro-orifice 210; when the nozzle 200 moves to the second working position due to blockage, the slider 300 moves from the first working position to the second working position under the action of the second driving structure 500, and at this time, the insertion rod 310 is inserted into the micro-orifice 210, so that the foreign matter in the micro-orifice 210 is pushed out from the other side of the micro-orifice 210, and the nozzle 200 is dredged, thereby achieving the purpose of dredging the nozzle 200, and meanwhile, the foreign matter cannot return to the body 100 to cause blockage to the nozzle 200 again.

The locking structure 600 is used to lock the nozzle 200 in either the first or second operating position. Specifically, when the nozzle 200 is in the first operating position, the locking structure 600 locks the nozzle 200 in the first operating position; and when the nozzle 200 is in the second operating position, the locking structure 600 locks the nozzle 200 in the second operating position.

When the nozzle 200 is blocked in use, the nozzle 200 is firstly moved from the first working position to the second working position under the action of the first driving structure 400, in the process, the locking structure 600 firstly releases the locking of the nozzle 200, and the nozzle 200 is locked again after being moved to the second working position; then the slider 300 moves from the first working position to the second working position under the action of the second driving structure 500, and in the process, the inserted rod 310 is inserted into the micro-jet holes 210, so that the peculiar smell in the micro-jet holes 210 is pushed out, and the nozzle 200 is dredged; then the slider 300 moves from the second working position to the first working position under the action of the second driving structure 500, and in the process, the plunger 310 is pulled out from the micro-jet hole 210; finally, the nozzle 200 is moved from the second operating position to the first operating position by the first actuating structure 400 for continued use.

In one embodiment, the first drive configuration 400 includes a first permanent magnet 410, a first electromagnet 420.

Wherein, the first permanent magnet 410 is embedded at the bottom of the nozzle 200. The first electromagnet 420 is embedded under the nozzle 200.

In use, when the nozzle 200 needs to be moved from the first operating position to the second operating position, the first electromagnet 420 is energized and the magnetic properties of the side of the first permanent magnet 410 opposite the first electromagnet 420 are made the same, thereby generating a repulsive force between the first electromagnet 420 and the first permanent magnet 410, under the effect of which repulsive force the nozzle 200 is driven from the first operating position to the second operating position.

Similarly, when the nozzle 200 needs to move from the second working position to the first working position, the first electromagnet 420 is energized and the magnetic property of the side of the first permanent magnet 410 opposite to the first electromagnet 420 is made opposite, so that an attraction force is generated between the first electromagnet 420 and the first permanent magnet 410, and the nozzle 200 is driven from the second working position to the first working position by the attraction force.

The first driving structure 400 of this structure has a simple structure.

In one embodiment, the second drive configuration 500 includes a second permanent magnet 510 and a second electromagnet 520.

Wherein, the second permanent magnet 510 is embedded on the side of the slider 300 facing away from the nozzle 200. The second electromagnet 520 is embedded in a side of the mounting cavity 120 facing the second permanent magnet 510.

Specifically, when the slider 300 needs to be moved from the first operating position to the second operating position, the second electromagnet 520 is energized and makes the magnetic property of the side of the second permanent magnet 510 opposite to the second electromagnet 520 the same, so that a repulsive force is generated between the second electromagnet 520 and the second permanent magnet 510, and under the repulsive force, the slider 300 is driven from the first operating position to the second operating position.

Similarly, when the slider 300 needs to move from the second working position to the first working position, the second electromagnet 520 is energized and the magnetic property of the side of the second permanent magnet 510 opposite to the second electromagnet 520 is made opposite, so that an attraction force is generated between the second electromagnet 520 and the second permanent magnet 510, and the slider 300 is driven from the second working position to the first working position by the attraction force.

The second driving structure 500 of this structure has a simple structure.

In one embodiment, the locking structure 600 includes two sets of locking units 610, and the two sets of locking units 610 are sequentially spaced along the longitudinal direction. Specifically, the two sets of locking units 610 correspond to the first and second operating positions of the nozzle 200, respectively. Thus, when the nozzle 200 is in the first operating position, it is locked by the locking unit 610 in the first operating position, and when the nozzle 200 is in the second operating position, it is locked by the locking unit 610 in the second operating position.

Specifically, the locking unit 610 includes a locking block 611, an elastic member 612, and a locking hole 613 opened on the nozzle 200.

The body 100 is provided with a slide hole 140, the slide hole 140 is communicated with the slide groove 110, and the slide block 300 is slidably inserted in the slide hole 140.

The elastic member 612 is installed in the slide hole 140, and naturally, the elastic member 612 has a tendency to move the slider 300 in a direction to approach the nozzle 200.

Wherein the ends of the locking blocks 611 facing the nozzle 200 are provided as slopes close to each other, and the locking holes 613 are adapted to the ends of the locking blocks 611 facing the nozzle 200.

In use, during the movement of the nozzle 200 from the first working position to the second working position, the first electromagnet 420 is energized, and a repulsive force is generated between the first electromagnet 420 and the first permanent magnet 410, under the repulsive force, the nozzle 200 can push the locking block 611 away from the nozzle 200 through the inclined surface, and therefore, the locking block 611 does not affect the movement of the nozzle 200. And when the nozzle 200 is moved to the second working position, since the locking hole 613 corresponds to the locking block 611 located at the second working position, the locking block 611 is pushed into the locking hole 613 by the elastic member 612, thereby locking the nozzle 200 to lock the nozzle 200 at the second working position.

Similarly, when the nozzle 200 moves from the second working position to the first working position, the first electromagnet 420 is energized, and an attractive force is generated between the first electromagnet 420 and the first permanent magnet 410, and under the attractive force, the nozzle 200 can push the locking block 611 away from the nozzle 200 through the inclined surface, so that the locking block 611 does not affect the movement of the nozzle 200. When the nozzle 200 is moved to the first working position, since the locking hole 613 corresponds to the locking block 611 located at the first working position, the locking block 611 is pushed into the locking hole 613 by the elastic member 612, thereby locking the nozzle 200 to lock the nozzle 200 at the first working position.

The locking structure of the structure has simple structure and reasonable design.

In one embodiment, the number of the nozzles 200 is two, the two sliding grooves 110 are spaced apart from each other on the body 100, the two nozzles 200 are slidably mounted in the two sliding grooves 110, and the magnetic properties of the first permanent magnets 410 embedded at the bottoms of the two nozzles 200 facing the first electromagnet 420 are opposite.

In use, initially, one nozzle 200 is in the first operating position and the other nozzle 200 is in the second operating position. When the nozzle 200 in the first operating position is blocked, the first electromagnet 420 is energized and made to have the same magnetic properties on the side opposite to the first permanent magnet 410 on the nozzle 200, thereby generating a repulsive force, under the effect of which the nozzle 200 is driven to the second operating position. Since the first permanent magnets 410 mounted on the two nozzles 200 have opposite polarities on the sides facing the first electromagnets 420. Therefore, the first permanent magnet 410 mounted on the other nozzle 200 is opposite in magnetism to the opposite side of the first electromagnet 420, so that an attraction force is generated in its holder, and the nozzle 200 is driven from the second operating position to the first operating position by the attraction force.

By the structure, the two nozzles 200 are arranged, so that when one nozzle 200 is blocked, the other nozzle 200 can still be used, and the working efficiency is improved. Meanwhile, the magnetism of the first permanent magnets 410 embedded at the bottoms of the two nozzles 200 on the side facing the first electromagnet 420 is set to be opposite, so that the first driving structure 400 can drive one of the nozzles 200 to move from the first working position to the second working position and simultaneously drive the other nozzle 200 to move from the second working position to the first working position, and the structure is simple and reasonable in design.

In one embodiment, the periphery of the slider 300 is sealed with the mounting cavity 120, and the slider 300 is provided with a plurality of ventilation holes 320.

When the air-permeable sliding block 300 is used, the sliding block 300 and the mounting cavity 120 are kept sealed, so that the sliding block 300 and the mounting cavity 120 are in the same structure as a syringe, after the air vents 320 are formed, in the process that the sliding block 300 moves from the first working position to the second working position, air enters the mounting cavity 120 from the air vents 320 so as to prevent negative pressure from being formed in the mounting cavity 120 and influencing the movement of the sliding block 300.

In the process that the sliding block 300 moves from the second working position to the first working position, the air in the mounting cavity 120 can flow out at a high speed through the air holes 320 under the action of the sliding block 300, so that foreign matters left when the nozzle 200 is dredged are blown away to prevent the foreign matters from being adhered to the nozzle 200.

In one embodiment, a plurality of locking units 610 are included in any one set of locking units 610, and the plurality of locking units 610 are respectively located at two sides of the sliding chute 110.

With this structure, the locking units 610 are provided on both sides of the nozzle 200, so that the nozzle 200 is locked better, thereby improving the locking effect.

In one embodiment, the number of the airing holes 320 is equal to and corresponds to the number of the inserting rods 310. Specifically, the airing hole 320 is provided along the axis line of the insert rod 310 and the slider 300.

In use, when the slider 300 moves from the first working position to the second working position, air enters the mounting cavity 120 through the air holes 320, so that negative pressure is prevented from being formed in the mounting cavity 120 due to the movement of the slider 300, and the movement of the slider 300 is prevented from being influenced.

And in the process that the sliding block 300 moves from the second working position to the first working position, air in the mounting cavity 120 flows out at a high speed through the air holes 320 under the action of the sliding block 300. Since the airing holes 320 are formed along the axial line of the insert rod 310, the air in the installation cavity 120 is accurately guided to the micro-spray holes 210 by the airing holes 320, thereby blowing off foreign materials adhered to the micro-spray holes 210.

This structure facilitates blowing off foreign substances adhered to the micro-orifice 210.

Of course, a storage battery and a controller are mounted on the body for supplying power to the electromagnets and for controlling the current directions of the first electromagnet and the second electromagnet.
