Description

Technical Field

[0001] This utility model relates to the field of oil container technology, and in particular to an oil sprayer. Background Technology

[0002] Commercially available cooking oils are generally quite bulky. Pouring them directly into the pan is not only inconvenient but also makes it difficult to control the amount used. Furthermore, for a healthy lifestyle, controlling oil consumption is generally encouraged. Traditionally, people pour large containers of oil into oil jugs or bottles. However, these methods don't allow for precise control of the oil volume and result in uneven pouring, which is especially inconvenient when grilling. To address this, spray bottles were developed. Compared to the traditional method of pouring oil, spray bottles use a nozzle to distribute the oil more evenly. The spray is either a mist or liquid, making it easier to control the amount of oil sprayed and preventing waste. Existing press-type spray bottles require pressing the cap to spray oil from the nozzle. However, the nozzle moves during this pressing process, leading to inaccurate spray direction and position, and inconsistent performance. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an oil sprayer.

[0004] This utility model is achieved through the following technical solution: an oil sprayer, comprising a body, a head, a support base, a check valve, a straw, a button, a three-way connector, and a nozzle; the support base is installed on the top of the body, the head is detachably installed on the support base, and the support base is located inside the head; the first port of the three-way connector passes through the support base, the check valve is installed inside the support base and communicates with the first port of the three-way connector, the upper end of the straw is detachably connected to the check valve, and the lower end of the straw extends into the bottom of the body; the second port of the three-way connector is detachably installed on the nozzle, and the nozzle is installed in the opening at the top of the head; a pressure structure for drawing oil from the body and spraying oil out of the container is detachably installed in the third port of the three-way connector, and the button is connected to the pressure structure.

[0005] The combination of the check valve and pressure mechanism draws oil from the container into the T-connector, and the pressure mechanism then sprays the oil out of the container from the T-connector, thus achieving the oil spraying function. The check valve controls the unidirectional flow of oil; releasing the button returns the check valve to its initial state, with the oil inside the T-connector. Pressing the button again allows the oil to be sprayed out. The detachable design facilitates easy cleaning of the oil container. The nozzle and button are located in different positions, ensuring that pressing does not affect the nozzle's position, thereby improving the spraying effect.

[0006] The pressure structure includes a piston rod, a piston body, and a first spring. The piston body is sleeved on the outer periphery of the piston rod and abuts against the rear side of the piston rod head. The outer surface of the piston body abuts against the inner wall of the third interface of the tee pipe and can slide along the inner wall. One end of the first spring abuts against the inner wall of the third interface of the tee pipe, and the other end abuts against the front side of the piston rod head. The button is sleeved on the end of the piston rod. The first spring provides elastic force to press the piston rod against the piston body, returning the button to the released position.

[0007] The check valve structure includes a check valve tube, a second spring, and a check valve bead. The check valve tube includes a first channel and a second channel communicating with it. The first channel and the second channel form a channel penetrating the check valve tube. The upper end of the suction tube is inserted into the second channel. The second spring and the check valve bead are located in the first channel. The upper end of the second spring is sleeved on the outer periphery of the first interface of the three-way tube, and the lower end of the second spring presses against the check valve bead to seal the connection between the first channel and the second channel.

[0008] The support base has a positioning cylinder with a first mounting hole and a downward opening at its center. A second mounting hole is formed on the upper side of the positioning cylinder, communicating with the first mounting hole. A positioning ring groove is formed inside the positioning cylinder, encircling the first mounting hole. The first interface of the tee pipe passes through the second mounting hole and is located within the first channel of the check pipe. A raised ring protrudes outward from the upper outer circumference of the check pipe, and the upper end of the check pipe is inserted into the first mounting hole. The raised ring engages with the positioning ring groove. The cooperation between the positioning ring groove and the raised ring ensures a stable fit between the check pipe and the support base.

[0009] It also includes a sealing gasket, which is fitted around the outer periphery of the first interface of the tee pipe located within the first mounting hole. The upper end of the second spring abuts against the sealing gasket, and the upper end face of the check pipe abuts against the sealing gasket. The check pipe is a pipe fitting made of plastic with elastic deformation properties. The tee pipe is provided with a positioning element, which rests on the upper side of the positioning cylinder when the first interface of the tee pipe passes through the second mounting hole. The sealing gasket increases the sealing performance and effectively prevents oil leakage. The positioning element allows the positioning cylinder of the support base to provide stable support for the tee pipe.

[0010] The lower end of the first channel is a frustum-shaped hole, which communicates with the second channel. The check valve is located inside the frustum-shaped hole. The frustum-shaped hole at the lower end of the first channel facilitates sealing of the hole after the check valve falls back down.

[0011] The top of the kettle body bends inward and extends upward to form an annular retaining ring. The annular retaining ring and the outer wall of the kettle body have a horizontally set first position. The lower outer periphery of the support base extends downward to form a sleeve. The sleeve is screwed onto the outer periphery of the annular retaining ring by a threaded connection and placed on the first position. The kettle head is fixed to the support base by a buckle, and the lower side of the kettle head is placed on the first position.

[0012] The kettle head has a third mounting hole on its front side, and the third interface of the tee pipe faces the third mounting hole. The button has a first sleeve and a second sleeve arranged concentrically, with the first sleeve located inside the second sleeve. The first sleeve is embedded in the third interface of the tee pipe, and the second sleeve is sleeved outside the third interface of the tee pipe. The end of the piston rod is sleeved inside the first sleeve. The head of the piston rod protrudes forward to form a boss, and a second stage is formed around the boss. The end of the first spring is sleeved on the outer circumference of the boss and abuts against the second stage. The cooperation of the first sleeve and the second sleeve can tightly connect the button to the third interface of the tee pipe. The boss on the front side of the piston rod head can position the first spring for better rebound.

[0013] The nozzle has a frustum-shaped structure with a fourth mounting hole on its rear side and an oil injection hole on its front side. The oil injection hole communicates with the fourth mounting hole and extends through both sides of the nozzle. The second interface of the tee pipe is inserted into the fourth mounting hole. The diameter of the front side of the nozzle is smaller than the diameter of its rear side. The oil injection hole includes a horizontal hole and a frustum-shaped hole communicating with it. The horizontal hole communicates with the fourth mounting hole, and the frustum-shaped hole has a gradually expanding diameter structure from the horizontal hole outwards from the container. The frustum-shaped nozzle, with its smaller diameter at the front side than at the rear side, prevents the nozzle from falling off. The gradually expanding diameter structure of the frustum-shaped hole outwards from the horizontal hole allows for better diffusion and distribution of the sprayed oil, resulting in more uniform spraying.

[0014] The second interface of the three-way pipe includes a first injection channel and a second injection channel. The second injection channel is connected to the first interface and the third interface of the three-way pipe. The lower end of the first injection channel is connected to the second injection channel, and the upper end of the first injection channel is connected to the nozzle. The first injection channel is an upwardly inclined channel.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This oil sprayer uses a button to drive the piston movement of the pressure structure. With the cooperation of the check valve structure, the oil is drawn from the body of the sprayer into the three-way pipe, and the pressure structure sprays the oil out of the sprayer from the three-way pipe. When the button is pressed, it will not cause the nozzle to move. The check valve of the check valve structure blocks the passage of the check valve pipe, so that the liquid in the three-way pipe cannot flow back. The nozzle is designed so that the oil spray is fan-shaped and the oil spray is more uniform. This device can reduce waste and effectively control the amount of oil used. Attached Figure Description

A pressure structure for drawing oil from the body 1 and spraying oil out of the container is detachably installed in the third port of the three-way connector 6, and the button 5 is connected to the pressure structure.

[0028] The combination of the check valve and the pressure mechanism allows oil to be drawn from the container body 1 into the three-way pipe 6, and then sprayed out of the container through the pressure mechanism, thus achieving the oil spraying function. The check valve controls the unidirectional flow of oil. Releasing button 5 returns the check valve to its initial state, with the oil inside the three-way pipe 6. Pressing button 5 again will then spray the oil out. The detachable structure facilitates cleaning of the oil container later. The nozzle 7 and button 5 are located in different positions, so pressing them will not affect the position of the nozzle 7, thereby improving the oil spraying effect.

The upper end of the check pipe 91 is inserted into the first mounting hole 32, and the raised ring 911 is engaged in the positioning ring groove 34. The cooperation between the positioning ring groove 34 and the raised ring 911 can stably connect the check pipe 91 and the support base 3.

[0032] It also includes a sealing gasket 94, which is fitted around the outer periphery of the first interface of the tee pipe 6 located in the first mounting hole 32. The upper end of the second spring 92 abuts against the sealing gasket 94, and the upper end face of the check pipe 91 abuts against the sealing gasket 94. The check pipe 91 is a pipe fitting made of plastic with elastic deformation properties. The tee pipe 6 is provided with a positioning element 61. When the first interface of the tee pipe 6 passes through the second mounting hole 33, the positioning element 61 rests on the upper side of the positioning cylinder 31. The sealing gasket 94 can increase the sealing performance and effectively prevent oil from overflowing. The positioning element 61 can make the positioning cylinder 31 of the support base 3 provide stable support for the tee pipe 6.

[0033] The lower end of the first channel has a frustum-shaped hole, which connects to the second channel. The check bead 93 is located inside the frustum-shaped hole. The frustum-shaped hole at the lower end of the first channel facilitates sealing of the hole after the check bead 93 falls back down.

The cooperation of the first sleeve 51 and the second sleeve 52 can tightly connect the button 5 to the third interface of the three-way pipe 6. The boss 811 on the front side of the head of the piston rod 81 can position the first spring 83 and better realize the rebound.

[0036] The nozzle 7 has a frustum-shaped structure with a fourth mounting hole 71 on its rear side and an oil injection hole 72 on its front side.

The oil injection hole 72 includes a horizontal hole and a frustum-shaped hole communicating with it. The horizontal hole communicates with the fourth mounting hole 71, and the frustum-shaped hole has a gradually expanding diameter structure from the horizontal hole outwards from the container. The frustum-shaped nozzle 7, with its smaller diameter at the front side than at the rear side, prevents the nozzle 7 from falling off.

[0039] Installation in this embodiment:

[0040] 1) Fit the nozzle 7 onto the opening at the upper end of the three-way pipe 6;

[0041] 2) Place the three-way tube 6 below the kettle head 2, and insert the nozzle 7 from bottom to top onto the top of the kettle head 2;

[0042] 3) Place the support base 3 below the three-way pipe 6, and clamp the support base 3 onto the lower end of the kettle head 2 from bottom to top, so that the lower end of the three-way pipe 6 is inserted into the set position of the support base 3;

[0043] 4) Place the piston body 82 on the left end of the piston rod 81, and fit the piston onto the piston rod 81 at the set position from left to right;

[0044] 5) Place the piston rod 81 on the right end of the button 5, and screw the piston rod 81 into the position set by the button 5 from right to left;

[0045] 6) Place the first spring 83 on the left side of the three-way tube 6, and insert the first spring 83 into the left through hole (third interface of the three-way tube 6) from left to right;

[0046] 7) Place button 5 on the left side of the T-pipe 6, and thread button 5 through the pipe opening (third interface of T-pipe 6) on the left side of the T-pipe 6 from left to right;

[0047] 8) Place the sealing gasket 94 below the support base 3 and thread the sealing gasket 94 through the bottom hole (second mounting hole 33) of the support base 3 from bottom to top;

[0048] 9) Place the check bead 93 above the check tube 91 and insert the check bead 93 into the check tube 91 from top to bottom;

[0049] 10) Place the second spring 92 above the check tube 91, and insert the second spring 92 into the check tube 91 from top to bottom to press down the check bead 93;

[0050] 11) Place straw 4 below check tube 91 and insert straw 4 into the through hole (second channel) below check tube 91 from bottom to top;

[0051] 12) Place the check pipe 91 under the support base 3, and insert the check pipe 91 from bottom to top under the support base 3, and press down the sealing gasket 94.

[0052] 13) Place the pot head 2 on top of the pot body 1, and screw the pot head 2 onto the pot body 1 from top to bottom and tighten it.

[0053] The working principle of this embodiment:

[0054] When the fuel injector is in the released state, press button 5 on the fuel injector. The piston 82 compresses the liquid in the three-way tube 6. Since the check valve 93 blocks the lower through hole of the check valve 91, the liquid in the three-way tube 6 can only pass through the upper through hole of the three-way tube 6 and then be atomized and sprayed forward through the nozzle 7, completing the spraying action. Release button 5, and the piston will pop out to the left under the force of the first spring 83, creating a negative pressure in the three-way tube 6. The negative pressure causes the liquid in the injector to pass through the suction tube 4, pushing the check valve 93 up and into the three-way tube 6. When the air pressure in the three-way tube 6 is equal to the air pressure in the injector, the second spring 92 will press the check valve 93 down, causing the check valve 93 to block the lower through hole of the check valve 91, preventing the liquid in the three-way tube 6 from flowing back, thus completing the suction action.

[0055] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
