With the improvement of living standard, the requirement of people on environmental sanitation is also improved, so that various liquid sanitary products such as disinfectants and the like are increasingly widely used. Liquid sanitary products, such as various liquid disinfectants, insect killers and the like, are atomized and then sprayed out, namely, the liquid sanitary products are made into an aerosol form, and the liquid sanitary products are more popular because of the convenience in use.

Since the aerosol is in liquid form when it is sold on the market, but it is sprayed in an atomizing manner when it is used, the aerosol product is sprayed after being atomized by a spray head. In particular, the canister containing the aerosol is integrally provided, either mounted to a spray head device or with the spray head itself.

The aerosol products in the market at present are gaseous at normal temperature except for some aerosol adopted by the products, so that the aerosol products can be automatically vaporized/atomized only by being sprayed out from a high-pressure container through a spray head. Most products, which are stored in a canister as an aerosol liquid, are then atomized from a spray head under pressure and then sprayed. In the spraying process, the automatic spraying can be divided into two types, one type is automatic spraying, the tank body is provided with a spray head, and high pressure is arranged in the tank body, so that liquid in the tank body automatically flows into the spray nozzle under high pressure and is sprayed out after being atomized as long as the spray head is opened (pressed). Such as common household spray can type insect control products. The other type is manual spraying, namely the spray head is provided with a pressing handle which can rebound instantly, the spray head moves by a reciprocating piston under manual action, positive pressure is generated in the tank body, and then liquid in the tank body is pressed into a suction pipe and then is conveyed to a spray nozzle, and the liquid is sprayed after atomization.

In the aerosol product of manual spraying usually, the shower nozzle can set up with jar body integration, also can separate the setting, and when using, only need with jar body connection to the shower nozzle and seal to insert the straw below the liquid level of aerosol in jar, come and go the extrusion and press the handle, can work. The required spraying pressure is low, the spraying range is small, and the portable multifunctional spraying device is suitable for being carried about, used at any time and used for disinfecting the self or the environment.

At present, the aerosol spray head used for manual spraying in the market can press the pressing handle to spray the aerosol in the connected tank body only by small pressure. The aerosol is easily ejected by mistake, for example, by being put in a bag and squeezed, or by mistake by a child. Considering that the aerosol can be a drug or even a disinfectant, there is a certain safety risk.

Furthermore, there is an aerosol spray head on the market, which has a protective cap screwed on, and when not in use, the cap is screwed on by screw threads and covers the spray head, so that the aerosol in the tank cannot flow out because the outlet is blocked. However, because the protective cover is connected by the screw thread, the protective cover can be taken off only by screwing a plurality of turns when in use, which wastes time. Meanwhile, when the protective cover is covered after spraying, residual liquid drops at the spray head can be adhered to hands, so that certain safety and sanitation problems exist, particularly when the aerosol is a disinfection/insecticidal liquid.

Accordingly, the prior art is subject to further improvements and enhancements.

Detailed Description

The utility model provides an aerosol shower nozzle and aerosol spray can, for making the utility model discloses a purpose, technical scheme and effect are clearer, make clear and definite, and it is right with the example to refer to the attached drawing below the utility model discloses do further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model discloses an aerosol shower nozzle, during operation, a jar body of registration constitutes an aerosol spray can. The general structure of the aerosol spray can is shown in a cross-sectional view in fig. 1, and comprises an upper aerosol spray head and a can body 200 which is sleeved and connected with the lower part of the can body through a sealing ring 210, wherein the can body 200 stores an aerosol 250 in a liquid state. The upper aerosol nozzle, as shown in fig. 1, includes a nozzle body 100, a side surface of the nozzle body 100 is provided with a nozzle hole 150, and an inner side surface of the nozzle hole 150 is communicated with the tank 200. That is, the aerosol liquid in the can 200 is atomized from the nozzle 150 and discharged when in use. The outer side 110 of the nozzle hole 150 is preferably recessed from the center to the inner side, and is flared, that is, the nozzle hole 150 is flared, so that the aerosol can be sprayed and dispersed conveniently, and the coverage area of the aerosol is increased.

For better atomization, in a preferred embodiment, a mesh structure is further provided in the nozzle 150, such as a porous mesh 600, or the diameter of the opening of a single nozzle 150 is set to be very small, but a plurality of nozzles 150 are arranged in a substantially parallel and adjacent manner. I.e. by separating and fragmenting the spray path of the spray orifice 150 to break up the liquid aerosol into small droplets as much as possible, thereby improving the atomization effect.

Since the can 200 is generally disposed below the nozzle 150, a straw 120 may be disposed, an upper end of the straw 120 is communicated with an inner side surface of the nozzle 150, and another end, i.e., a lower end, of the straw 120 extends into the can 200 and is inserted into the aerosol 250. That is, aerosol 250 in canister 200 is connected to orifice 150 via straw 120, so that it can be atomized and ejected through orifice 150 under pressure. When the aerosol 250 is driven to flow upward into the suction pipe 120 by applying pressure to the gas in the canister 200, the canister 200 needs to be hermetically connected to the head body 100. For example, as shown in fig. 1, the canister 200 is sleeved under the spray head body 100 through a sealing ring 210, and the aerosol 250 in the canister 200 ascends through the suction pipe 120 and enters into the spray hole 150 under the external pressure, for example, the air pressure increased by the external drive on the liquid surface in the canister 200.

Wherein, increasing the gas pressure of the gas above the aerosol 250 can be accomplished by providing a pressurizing structure. Such as an automated booster pump. Of course, it is preferable to increase the air pressure manually, that is, a pressing handle 300 is further provided on the nozzle body 100, one end of the pressing handle 300 is rotatably connected to the nozzle body 100, and the pressing handle 300 is connected to drive a piston 310 to translate, and the piston 310 charges the gas into the can 200. As shown in fig. 1, a check valve 320 is disposed on the nozzle body 100 near the connection between the canister 200 and the nozzle body 100, and when the pressing handle 300 is manually pressed, the piston 310 is pushed to translate leftwards in fig. 1, so as to reduce the volume of the gas in the canister 200, increase the pressure of the gas in the canister 200, on one hand, close the check valve 320, and on the other hand, press the aerosol 250 to enter the suction tube 120 from below the suction tube 120 and go upwards to the nozzle 150, so as to atomize and spray. The pressing handle 300 is then restored to its original position, for example, rebounded by the elastic member 330, such as a spring, and, as the volume inside the can 200 increases, the air pressure decreases, the check valve 320 is opened, and the external atmosphere is sucked into the can 200. This is repeated, and the aerosol 250 of the liquid is intermittently and continuously pressed into the nozzle hole 150, and is atomized and discharged.

In view of the fact that the atomizing agent 250 can be driven to be ejected from the ejection hole 150 without using too much pressure, the present invention provides an improvement on an atomizing agent spraying head, wherein an ejection hole plug 500 movably connected to the spraying head body 100 is added, and specifically includes an outwardly protruding head 510, the protruding head 510 is adapted to the ejection hole 150, and can block the ejection hole 150 from the outer side surface of the ejection hole 150, i.e., the ejection hole 150 can be blocked or covered by the protruding head 510, so as to stop the atomizing agent 250 from being ejected from the ejection hole 150 continuously. After the orifice plug 500 is opened, i.e., the orifice plug 500 is separated from the orifice 150, the aerosol spray head can be operated continuously to spray the atomized aerosol 250.

The specific implementation of the nozzle plug 500 may be various. In a first embodiment, the protruding head 510 is provided on a cover plate 520 protruding towards and in alignment with the orifice 150, as shown in the perspective view of the open orifice plug 500 when the aerosol spray head of fig. 2 is in operation. When the nozzle hole 150 is covered by the nozzle hole plug 500, the cover plate 520 is preferably substantially parallel to the outer side surface 110. The specific connection position of the orifice plug 500 and the nozzle body 100 is selected to be located above the orifice 150, such that the orifice plug 500 is opened and then completely separated from the spray range of the orifice 150 from above, thereby preventing the spray from being blocked and preventing the orifice plug 500 from being contaminated. Specifically, as shown in the cross-sectional view of the aerosol nozzle in fig. 3 during operation, the nozzle plug 500 is movably connected to the nozzle body 100 through a rotating shaft 530 substantially parallel to the outer side surface 110, that is, the nozzle plug 500 is axially connected to the outer side surface 110 through the rotating shaft 100 and can be opened and closed for rotation. The rotation shaft 530 is specifically disposed above the nozzle hole 150, and preferably, when the outer side surface 110 protrudes/is exposed from one side surface of the nozzle body 100, the rotation shaft 530 is disposed at an upper edge of the outer side surface 110. After the nozzle hole plug 500 is thus opened, a space for rotation may be left for the handle 550, i.e., the handle 550 may be attached to the upper surface of the nozzle body 100 after being rotated.

In a second embodiment, as shown in the cross-sectional view of the aerosol spray head of fig. 4, the orifice plug 500 is connected to the orifice 150 by a resilient strip 560. Wherein the elastic force of the elastic strip 560 is used to keep the orifice plug 500 away from the orifice 150. That is, after the orifice plug 500 is separated from the orifice 150, the elastic strip 560 elastically restores the original shape to lift the orifice plug 500 upward and away from the ejected aerosol 250, so as to ensure the cleanness of the orifice plug 500. Meanwhile, the elastic strip 560 can more conveniently connect the nozzle plug 500 and the nozzle body 100, and the connection mode is more selected.

In view of facilitating the closing and opening of the protrusion head 510 while preventing access to the cover plate 520, the present invention provides that an outwardly extending handle 550 is attached to the nozzle plug 500, for example, to one side of the cover plate 520, to extend outwardly in a manner away from the protrusion head 510, thereby preventing contamination with the atomizing agent 250. In particular, after the nozzle plug 500 blocks the nozzle hole 150, the handle 550 is located above the nozzle hole 150 and points away from the nozzle hole 150, thereby preventing droplets of the aerosol accumulated at the nozzle hole 150 from dropping onto and contaminating the handle 550. In a preferred embodiment, as shown in fig. 1, the handle 550 is further bent away from the outer side 110, so that when the nozzle plug 500 is opened, the upper edge of the nozzle body 100 does not block the handle 550, thereby ensuring that the nozzle plug 500 is completely opened and out of the spraying range of the atomizing agent 250.

In the above embodiment, the protruding head 510 is plugged by inserting and plugging the nozzle hole 150 to prevent the atomizing agent 250 from being ejected by mistake, and at this time, the outer side surface 110 is formed in a trumpet shape, which also facilitates the insertion of the protruding head 510 into the nozzle hole 150. In a more preferred embodiment, an outer layer made of an elastic material, such as a rubber material, may be further covered on the outer layer of the protruding head 510, so that after the cup is inserted into the nozzle 150, due to the elastic deformation of the rubber material, the friction force and the sealing degree between the protruding head 510 and the nozzle 150 are relatively large, and thus the cup can bear a larger gas pressure in the can 200, and further it is ensured that the atomizing agent 250 is not ejected due to the increase of the gas pressure in the can 200 caused by the mispressing, which bounces off the protruding head 510.

In another embodiment, blocking the misting agent 250 from being ejected by mistake can also be achieved by covering all of the outer side 110 of the orifice 150. As shown in the cross-sectional view of fig. 5, the outer side surface 110 protrudes from the side surface of the nozzle body 100, the protruding head 510 is provided with a circle of protrusions to form a protruding ring 540, and the protruding ring 540 can be sleeved on the outer side surface 110 to block the nozzle hole 150. That is, the outer side surface 110 is closed to close the nozzle 150, and particularly, the inner side surface of the raised ring 540 is also made of an elastic material such as rubber, and is also used to increase friction and sealing degree and prevent the gas in the can 200 from being blown away.

Based on foretell aerosol shower nozzle, the utility model also discloses an aerosol spouts jar, with above arbitrary shower nozzle body 100, the cover is located and is deposited the top of the jar body 200 of aerosol 250 can adopt fixed connection or detachable connection, but need be sealing connection, and guarantee aerosol 250 can follow orifice 150 atomizes and spouts. When the aerosol canister is used, the handle 550 is used to open the nozzle plug 500 upwards, so that the aerosol can be driven to atomize and spray through the nozzle 150 after leaving the spraying range of the nozzle 150. After the use, the handle 550 turns down the orifice plug 500, so that the protruding head 510 is plugged into the orifice 150, or the protruding ring 540 covers the outer side surface 110, thereby blocking the outlet of the aerosol 250 and preventing the aerosol from being ejected by misoperation.

To sum up, the utility model discloses an aerosol spray head and aerosol spray can, wherein, aerosol spray head, including shower nozzle body 100 and with shower nozzle body 100 swing joint's orifice stopper 500 can open and shut at the lateral surface of orifice 150, orifice stopper 500 is including the protruding head that can shutoff orifice 150 and being used for opening and shutting orifice stopper 500's handle 550, and handle 550 outwards leaves orifice 150 just is located the top of orifice 150. Thus, when the aerosol dispenser is not used, the protruding head 510 of the nozzle plug 500 is covered or blocked from the outer side surface of the nozzle hole 150 by the protruding handle 550, so that the aerosol 250 in the can 200 cannot be sprayed, and misoperation can be prevented. When in use, the nozzle plug 500 for plugging the nozzle hole 150 is easily turned upwards and opened by the handle 550. Moreover, since the handle 550 is disposed above the nozzle hole 150 and spaced from the nozzle hole 150 by a predetermined distance, the sprayed aerosol 250 is not contaminated or dropped on the handle 550, and thus, when the nozzle hole 150 is closed or the nozzle hole plug 500 is opened again, the aerosol 250 may not be left, thereby ensuring the hygiene and safety of the user.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
