Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In one embodiment, as shown in fig. 1, a liquid spraying apparatus 10 is provided, which comprises a spraying can 11, wherein a spraying passage 12 is provided in the spraying can 11 for guiding the liquid in the spraying can 11 to a nozzle 1131. In other words, assuming that the chamber for containing the liquid in the watering can 11 is the containing cavity 1111, the water spraying passage 12 is communicated with the containing cavity 1111, and one end of the water spraying passage 12 is located at the nozzle 1131 of the watering can 11, so that the liquid in the containing cavity 1111 can flow to the nozzle 1131 to be sprayed out. Specifically, the water spray passage 12 may be a pipe additionally provided in the watering can 11; alternatively, the water spray passage 12 is a channel integrally formed in the watering can 11, in other words, the watering can 11 itself encloses the water spray passage 12.

Further, in one embodiment, as shown in fig. 1, a water pump 1211 is disposed on the water spraying passage 12, and when the water pump 1211 is activated, the liquid in the containing cavity 1111 can be pumped out along the water spraying passage 12.

Further, in one embodiment, as shown in fig. 1, a first switch valve 1221 and a second switch valve 1222 are disposed on the water spray passage 12. A section of the water spray passage 12 between the first on-off valve 1221 and the second on-off valve 1222 is a first passage 123. The liquid spraying device 10 further comprises a manual pressure member 13, the manual pressure member 13 being provided with a pressure chamber 134 capable of elastic deformation. In other words, the pressing chamber 134 may be collapsed by pressing the manual pressing piece 13, and the pressing chamber 134 may be elastically restored when released. And the pressing chamber 134 communicates with the first passage 123. The first on-off valve 1221 is located closer to the nozzle 1131 than the second on-off valve 1222. When the squeezing chamber 134 is manually pressed, the first on-off valve 1221 is turned on, and the second on-off valve 1222 is turned off, so that the liquid in the squeezing chamber 134 and the first passage 123 is ejected from the nozzle 1131. When the pressing chamber 134 is released, the pressing chamber 134 is elastically deformed to restore its original size, the first switch valve 1221 is turned off, and the second switch valve 1222 is turned on, so that the liquid in the watering can 11 is sucked into the first passage 123 and the pressing chamber 134. So that the liquid in the liquid spray device 10 can be sprayed by manually repeatedly pressing the pressing chamber 134.

Specifically, the first switch valve 1221 and/or the second switch valve 1222 may be a check valve, or other valve body structure, which is not particularly limited herein, as long as the two switch valves can satisfy the following control procedure. When the volume of the squeezing chamber 134 is reduced, the first on-off valve 1221 is turned on, and the second on-off valve 1222 is turned off, so that the liquid in the squeezing chamber 134 and the first passage 123 is ejected from the nozzle 1131; when the pressing chamber 134 is released, the pressing chamber 134 is elastically deformed to restore its original size, the first switch valve 1221 is turned off, and the second switch valve 1222 is turned on, so that the liquid in the watering can 11 is sucked into the first passage 123 and the pressing chamber 134.

The above solution provides a liquid spraying apparatus 10, which can either pump out the liquid in the spraying pot 11 by using the water pump 1211 or manually spray out the liquid in the spraying pot 11 by continuously pressing the pressing cavity 134 in combination with the first switch valve 1221 and the second switch valve 1222. In other words, the liquid can be pumped out electrically or manually, so that the service life of the whole device is prolonged. When the water pump 1211 can normally operate, the liquid may be sprayed in an electric manner, and if the water pump 1211 malfunctions or the electric power in the liquid spraying apparatus 10 is insufficient, the mist may be manually sprayed.

In particular, the liquid spraying device 10 can be used for spraying disinfectant, i.e. containing disinfectant in the containing chamber 1111. The sterilizing water may be directly poured into the receiving chamber 1111, or manufactured in the receiving chamber 1111 using an electrolytic method. For example, a quantity of purified water and salt may be added to the receiving chamber 1111 to form a saline solution. The saline solution is then electrically electrolyzed using the electrolytic sheet 17 placed in the housing chamber 1111, thereby generating sodium hypochlorite, which is a highly effective chlorine-containing disinfectant. And spraying the sodium hypochlorite solution in an electric mode or a manual mode. The electric energy required by the sodium hypochlorite electrolysis process can be supplied by the power supply 14 for operating the water pump 1211, or the commercial power can be directly used.

Therefore, when the sodium hypochlorite is generated by electrolysis, the commercial power socket 16 is connected to commercial power.

Further, in one embodiment, as shown in fig. 1, a micro switch 18 is disposed in the watering can 11 for controlling the connection between the power source 14 and the water pump 1211. When it is desired to spray liquid in the electrically powered manner, the microswitch 18 is activated.

Further, in one embodiment, as shown in fig. 1 and 2, the manual pressing member 13 includes a second passage 131, a pressing block 132, and a restoring member 133. The second passage 131 communicates with the first passage 123, and the pressing block 132 is insertable into the second passage 131 to constitute the pressing chamber 134.

The second passage 131 comprises an auxiliary pipe 1311 and a contact housing 1312 which communicate with each other, in other words, a cavity surrounded by the contact housing 1312 communicates with the auxiliary pipe 1311. The auxiliary pipe 1311 communicates with the first passage 123. The contact housing 1312 is rotatably coupled to the kettle wall such that when the contact housing 1312 is depressed, the contact housing 1312 is able to rotate. When the contact housing 1312 rotates, the pressing block 132 is inserted into the contact housing 1312, the pressing block 132 and the contact housing 1312 are in sliding seal, and the compression spring is tightly pressed between the contact housing 1312 and the kettle wall. When the hand is released, the compression spring pushes the second passage 131 in a direction away from the pressing block 132.

Further, as shown in fig. 1, in one embodiment, the micro switch 18 is disposed corresponding to the contact housing 1312, such that when the contact housing 1312 is pressed to rotate, the micro switch 18 is triggered to turn on.

When it is desired to electrically spray the liquid, the contact housing 1312 may be lightly pressed to activate the micro switch 18, thereby activating the water pump 1211.

Further, as shown in fig. 1, in one embodiment, the watering can 11 includes a can body 111, a handle 112, and a can body 113.
