[0036] The grip-type spray device provided in the embodiment of the present application can realize the continuous spraying or liquid spraying function and has the characteristics of simple structure and easy operation.

[0037] like Figures 1 to 5 As shown, the grip-type spray device includes a liquid storage bottle 100, a cover body 200, a connecting cover 300 and a pressurizing member 400;

[0038] The liquid storage bottle 100 is made of a soft rubber material, for example, a silicone material or a medical plastic material. The liquid storage bottle 100 can be deformed when subjected to a squeeze force, thereby discharging the liquid.

[0039] The liquid storage bottle 100 has a raised bottle mouth 110;

[0040] The connection cover 300 is annular, and an annular ring 310 is provided on one side of the connection cover 300, and the inner diameter of the annular ring 310 is smaller than the inner diameter of the connection cover 300;

[0041] The bottle mouth portion 110 is embedded in the annular ring 310 of the connecting cover 300, and the end surface 120 of the bottle mouth portion 110 contacts the inner side surface of the annular ring 310;

[0042] The cover body 200 is connected to the other side of the connection cover 300 by threads, and a liquid outlet pipe 210 is also connected to the cover body 200 for discharging liquid; the cover body 200 has a cavity for passing liquid inside, and the liquid outlet pipe 210 is connected to the cavity;

[0043] The pressurizing member 400 is detachably connected to the inside of the cover body 200 or the connecting cover 300. The pressurizing member 400 is provided with at least one through hole 410 for pressurizing the liquid flow from the connecting cover 300 to the cover body 200.

[0044] The end surface of the cover body 200 and / or the pressurizing member 400 contacts the end surface 120 of the bottle mouth portion 110 , so as to fasten the end surface 120 of the bottle mouth portion 110 between the cover body 200 and the annular ring 310 .

[0045] During use, the liquid storage bottle 100 is continuously squeezed to allow the medicinal liquid to enter the connecting cover 300 through the bottle mouth 110, and the pressure-increasing member 400 is used to pressurize the water flow, so that the liquid passes through the liquid outlet pipe 210 of the cover body 200 and is sprayed out in an atomized state; when the pressure-increasing member 400 is removed, the liquid passes through the liquid outlet pipe 210 of the cover body 200 and is sprayed out in an atomized state; this solution has the characteristics of simple structure and easy operation, and can enable the spray device to switch between atomization and water flow states, enriching the patient's usage needs.

[0046] As a preferred embodiment, refer to Figure 1 and Figure 2 A concave snap-in portion 130 is provided on the circumferential side of the bottle mouth portion 110, and the snap-in portion 130 is embedded in the annular ring 310. The end face 120 of the bottle mouth portion 110 has a preset thickness, and the diameter of the end face 120 is greater than the diameter of the snap-in portion 130. When assembled with the connecting cover 300, the end face 120 of the bottle mouth portion 110 just recovers its original shape after flexible deformation and overlaps on one side of the annular ring 310 facing the cover body 200, and the snap-in portion 130 is concave and is snap-fitted to the inner wall of the annular ring 310.

[0047] As a preferred embodiment, the outer wall of the cover body 200 is provided with an external thread, and the inner wall of the connecting cover 300 is provided with an internal thread, so that the cover body 200 and the connecting cover 300 are threadedly connected.

[0048] As a preferred embodiment, refer to Figure 1 , Figure 4 and Figure 5 , the pressurizing member 400 includes a threaded connection portion 420 and an annular limiting portion 430;

[0049] The annular limiting portion 430 is connected to one side of the threaded connection portion 420. The annular limiting portion 430 can extend into the interior of the bottle mouth portion 110, and is used to fix the side wall of the bottle mouth portion 110 between the annular limiting portion 430 and the annular ring 310 along the circumferential direction. With this structural form, the bottle mouth portion 110 will not be deformed when the bottle body is squeezed by hand, ensuring that there will be no liquid leakage problem.

[0050] In addition, the threaded connection portion 420 is provided with at least one through hole 410 for passing liquid, which plays a role in pressurizing the liquid.

[0051] When the threaded connection portion 420 is threadedly connected to the inner wall of the cover body 200 , the end surface of the threaded connection portion 420 and / or the cover body 200 contacts the end surface 120 of the bottle mouth portion 110 ;

[0052] Specifically, since the threaded connection part 420 is connected to the inner wall of the cover body 200, when the end surface of the threaded connection part 420 facing the connection cover 300 is flush with the end surface of the cover body 200, at this time, the end surfaces of the threaded connection part 420 and the cover body 200 are respectively in contact with the end surface 120 of the bottle mouth part 110, and together play a role in squeezing and fixing the end surface 120 of the bottle mouth part 110;

[0053] When the end surface of the threaded connection portion 420 facing the connection cover 300 extends out of the end surface of the cover body 200, the end surface of the threaded connection portion 420 contacts the end surface 120 of the bottle mouth portion 110, thereby squeezing and fixing the end surface 120 of the bottle mouth portion 110;

[0054] When the end surface of the threaded connection portion 420 facing the connecting cover 300 extends into the interior of the cover body 200 , the end surface of the cover body 200 contacts the end surface 120 of the bottle mouth portion 110 , thereby squeezing and fixing the end surface 120 of the bottle mouth portion 110 .

[0055] When the threaded connection part 420 is threadedly connected to the inner wall of the connection cover 300 , the end surface of the threaded connection part 420 contacts the end surface 120 of the bottle mouth 110 . At this time, the end surface of the cover body 200 abuts against the end surface of the threaded connection part 420 away from the bottle body.

[0056] In this embodiment, a protrusion 421 is provided on at least one side of the threaded connection portion 420 (see Figure 5 The structure shown) or the groove-shaped control part is convenient for the user to operate by hand.

[0057] In addition, in this solution, the end of the liquid outlet pipe 210 can be connected to the nozzle 500 for use.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
