Description

Technical Field

[0001] This utility model relates to a spray bottle. Background Technology

[0002] The basic structure of a spray bottle in the prior art includes: a bottle body, a lid covering the bottle body, an air cylinder assembly located in the center of the lid and extending downward into the bottle body, and a vertically arranged suction pipe that can enter the bottle body. The lid has a valve seat located on one side of the air cylinder assembly. The valve seat has a horizontally oriented spray channel for communication with the nozzle, and a vertical valve chamber running vertically through the valve seat. The valve chamber is connected to the spray channel, and its lower end is connected to the suction pipe. The valve chamber contains a valve core that can move up and down. When the valve core is in the low position, it closes the lower opening of the valve chamber; when the valve core is in the high position, the lower opening of the valve chamber is open, allowing the suction pipe to communicate with the valve chamber. Typically, the valve core's low and high positions are switched using a button; pressing the button raises the valve core to the high position.

[0003] When in use, first inflate the kettle with air through the inflation component to generate high pressure inside the kettle. When you need to spray water, press down the button to open the water suction pipe and valve chamber. Under high pressure, water is sprayed out from the water suction pipe through the valve chamber and the water spray channel.

[0004] The existing spray bottle also has the drawback that the button needs to be pressed continuously when spraying water, which is inconvenient to operate. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of existing sprayers, this utility model provides a sprayer that is more comfortable and convenient to operate.

[0006] The technical solution of this utility model to solve its technical problem is: a spray bottle, including a bottle body, a bottle cap covered on the bottle body, an air cylinder assembly located in the center of the bottle cap and extending downward into the bottle body, and a vertically arranged water suction pipe that can enter the bottle body;

[0007] The kettle lid is provided with a valve seat located on one side of the air cylinder assembly. The valve seat has a horizontal water spray channel for communicating with the nozzle and a vertical valve cavity that runs through the valve seat from top to bottom. The valve cavity is connected to the water spray channel, and the lower end of the valve cavity is connected to and communicates with the water suction pipe.

[0008] The valve cavity is provided with a valve core that can move up and down. When the valve core is in the low position, it closes the lower opening of the valve cavity. When the valve core is in the high position, the lower opening of the valve cavity is open, so that the water suction pipe can communicate with the valve cavity.

[0009] The kettle lid is provided with a lever, the lever includes a sleeve that fits around the air cylinder assembly, the sleeve has a distal end connected to the valve core and a proximal end opposite to the distal end, a compression spring is provided below the proximal end, the upper end of the compression spring rests on the proximal end, and the lower end of the compression spring rests on the inside of the kettle lid.

[0010] The kettle lid has a handle, which is opposite to the water spray channel, and the proximal end of the lever extends into the handle to form a pressure plate;

[0011] The handle has a button cavity, and the button cavity has a button that can move up and down and back and forth. The button abuts against the pressure plate and thus protrudes from the handle under the action of the compression spring.

[0012] The lid has a first positioning plate and a second positioning plate extending downwards. The first positioning plate is located behind the second positioning plate, and the downward extension of the first positioning plate is less than the downward extension of the second positioning plate. The button has a forward-extending abutment plate, which initially rests against the lower end of the first positioning plate under the action of the compression spring.

[0013] The lid also includes a support rod. The upper end of the sleeve abuts against the lower end of the support rod, forming a fulcrum for the rotation of the lever. The abutment point between the sleeve and the support rod is located near the proximal end. Pressing the button down causes the lever to rotate around the fulcrum, thereby raising the distal end of the lever and causing the valve core to rise, thus opening the lower end of the valve cavity. Pushing the button forward again causes the abutment plate to abut against the lower end of the second positioning plate, thus keeping the button pressed down and keeping the lower end of the valve cavity open.

[0014] Furthermore, there are two support rods, which are symmetrical about the central plane of the sleeve.

[0015] Furthermore, the upper end of the sleeve is provided with a recessed fulcrum groove, and the lower end of the support rod is pressed against the fulcrum groove.

[0016] Furthermore, the distal end has a rearwardly extending connecting groove at its front end;

[0017] The upper end of the valve core is provided with a radially extending connector, the valve core is inserted into the connecting groove and the connector is located above the connecting groove.

[0018] Furthermore, the pressure plate has a strip-shaped hole extending forward and backward, and the lower end face of the button has a limiting post extending downward into the strip-shaped hole. The lower end of the limiting post has a limiting head extending radially. The limiting head is located below the strip-shaped hole, and in the initial state, under the action of the compression spring, the limiting head abuts against the back of the pressure plate.

[0019] Furthermore, the lid includes an upper lid body and a lower lid body that engages with the upper lid body, with the lower end of the compression spring resting on the lower lid body.

[0020] Furthermore, the upper cover body is provided with a downwardly extending upper connecting post, and the lower cover body is provided with an upwardly extending lower connecting post. The upper connecting post and the lower connecting post are connected by fasteners.

[0021] Furthermore, the button is provided with a downwardly extending guide piece, which abuts against the upper connecting post.

[0022] The beneficial effects of this utility model are as follows: when spraying water, after pressing the button, the button is pushed forward so that the abutment plate abuts against the lower end of the second positioning plate, thereby keeping the button in a downward-pressed state so that the lower opening of the valve cavity remains open, eliminating the need to keep pressing the button, making operation more comfortable and convenient.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-9 A spray bottle includes a bottle body 1, a bottle cap 2 covering the bottle body 1, an air cylinder assembly 3 located in the center of the bottle cap 2 and extending downward into the bottle body 1, and a vertically arranged water suction pipe (not shown in the figure) that can enter the bottle body 1.

[0034] The lid 2 is provided with a valve seat 4 located on one side of the air cylinder assembly 3. The valve seat 4 has a horizontal water spray channel 5 for communicating with the nozzle and a vertical valve cavity 6 that runs through the valve seat from top to bottom. The valve cavity 6 is connected to the water spray channel 5, and the lower end of the valve cavity 6 is connected to the water suction pipe.

[0035] The valve chamber 6 is equipped with a valve core 7 that can move up and down. When the valve core 7 is in the low position, it closes the lower opening of the valve chamber 6. To better seal the lower opening of the valve chamber 6, a sealing ring is usually provided at the lower part of the valve core 7 to achieve a better sealing effect. When the valve core 7 is in the high position, the lower opening of the valve chamber 6 is open, allowing the water suction pipe to communicate with the valve chamber 6.

[0036] The lid 2 is provided with a lever 8, which includes a sleeve 9 that is fitted over the air cylinder assembly 3. The sleeve 9 is provided with a distal end 10 connected to the valve core 7 and a proximal end 11 opposite to the distal end 10. A compression spring 12 is provided below the proximal end 11. The upper end of the compression spring 12 rests on the proximal end 11, and the lower end of the compression spring 12 rests inside the lid 2.

[0037] The kettle lid 2 has a handle 13, which is opposite to the water spray channel 5. The proximal end 11 of the lever extends into the handle to form a pressure plate 14. A button cavity is provided on the handle 12, and a button 15 that can move up and down and back and forth is provided in the button cavity. The button 15 abuts against the pressure plate 14, so that under the action of the compression spring 12, the button 15 protrudes outside the handle 13.

[0038] The lid 2 is provided with a first positioning plate 16 and a second positioning plate 17 extending downward. The first positioning plate 16 is located behind the second positioning plate 17, and the downward extension of the first positioning plate 16 is less than the downward extension of the second positioning plate 17. The button 15 has a forward-extending abutment 18. In the initial state, under the action of the compression spring 12, the abutment 18 abuts against the lower end of the first positioning plate 16.

[0039] The lid 2 is also provided with a support rod 19. The upper end of the sleeve 9 abuts against the lower end of the support rod 19 to form a fulcrum for the rotation of the lever 8. The abutment point of the sleeve 9 and the support rod 19 is located on the side near the proximal end 11 of the lever.

[0040] When spraying water, air is first injected into the kettle body 1 through the air inflation assembly to generate high pressure inside the kettle body 1. Then, the button 15 is pressed down to drive the lever 8 to rotate around the fulcrum (since there is space between the sleeve 9 and the air cylinder assembly 3, the lever can rotate without obstruction), thereby causing the distal end 10 of the lever to tilt up, thereby driving the valve core 7 to rise, and thus opening the lower end of the valve cavity 6. Then, the button 15 is pushed forward so that the abutment plate 18 abuts against the lower end of the second positioning plate 17, thereby keeping the button 15 in the downward pressed state so that the lower end of the valve cavity 6 remains open, thus connecting the water suction pipe (not shown in the figure) and the valve cavity 6. Under the action of high pressure, water is sprayed out from the water suction pipe through the valve cavity 6 and the water spray channel 5.

[0041] Inflatable components are a mature technology in the existing field, and will not be elaborated on here.

[0042] In one embodiment, there are two support rods 19, which are symmetrical about the central plane of the sleeve 9, so that the lever 8 rotates more smoothly and stably when pressed by the button 15.

[0043] In one embodiment, the upper end of the sleeve 9 is provided with a recessed fulcrum groove 20, and the lower end of the support rod 19 is pressed against the fulcrum groove 20, which can provide a more stable rotation support point, and the lever 8 rotates more smoothly and stably when pressed by the button 15.

[0044] In one embodiment, the connection between the distal end 10 of the lever and the valve core 7 is as follows: a rearwardly extending connecting groove 21 is provided at the front end of the distal end 10; a radially extending connector 22 is provided at the upper end of the valve core 7, the valve core 7 is inserted into the connecting groove 21 and the connector 22 is located above the connecting groove 21, so that the valve core 7 is held at the distal end of the valve core 7. Of course, other connection methods can also be used between the valve core and the distal end of the lever, such as hinges.

[0045] In one embodiment, the pressure plate 14 has a strip-shaped hole 23 extending forward and backward, and the lower end face of the button 15 has a limiting post extending downward into the strip-shaped hole 23. The lower end of the limiting post has a limiting head 24 extending radially. The limiting head 24 is located below the strip-shaped hole 23. In the initial state, under the action of the compression spring 12, the limiting head 24 abuts against the back of the pressure plate 14, which can further help the button 15 remain stable in the initial state.

[0046] In one embodiment, the lid 2 includes an upper lid body 2-1 and a lower lid body 2-2 that mates with the upper lid body 2-1, with the lower end of the compression spring 12 resting on the lower lid body 2-2. At this time, the first positioning plate 16, the second positioning plate 17, and the support rod 19 are mounted on the upper lid body 2-1.

[0047] In one embodiment, the upper cover 2-1 has a downwardly extending upper connecting post 25, and the lower cover 2-2 has an upwardly extending lower connecting post 26. The upper connecting post 25 and the lower connecting post 26 are connected by fasteners (e.g., screws).

[0048] In one embodiment, the button 15 is provided with a downwardly extending guide piece 27, which is close to the upper connecting post 25. When the button 15 is pressed down, the guide piece 27 moves downward along the connecting post 25, thus guiding the button 15.
