Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil sprayer technology, and in particular to an oil sprayer. Background Technology
[0002] Kitchen spray bottles are practical tools for controlling the amount of oil used. They spray cooking oil evenly onto food or cookware in a mist or fine spray, helping to reduce oil intake and improve cooking efficiency. Existing spray bottles, such as those with publication number CN221671530U, include an oil reservoir, a pump body mounted on the reservoir, a nozzle connected to the pump body, and a handle for triggering the pump. Pressing the handle draws oil from the reservoir and sprays it from the nozzle. However, if the handle is accidentally pressed, the oil may spray out unintentionally. Some spray bottles on the market have a locking mechanism to prevent accidental activation, but these mechanisms are either inconvenient to switch between locking and unlocking or not stable enough. Pressing the handle forcefully may cause the locking mechanism to loosen or break. Therefore, it is necessary to develop a spray bottle that is easy to operate and has a stable locking mechanism. Utility Model Content
[0003] In view of this, the present invention proposes an oil sprayer, the purpose of which is to improve the ease of operation and structural stability of the oil sprayer's locking function.
[0004] The solution provided by this utility model includes:
[0005] An oil sprayer includes an oil reservoir, a pump body mounted on the oil reservoir, a nozzle connected to the pump body, and a handle for triggering the pump body. The oil reservoir is provided with a protective cover covering the pump body and the nozzle. The protective cover includes a top cover and a locking mechanism, the locking mechanism comprising:
[0006] A locking element, the locking element comprising a slide block, a stop block disposed at the bottom of the slide block, and a toggle block disposed at the top of the slide block;
[0007] A fixing block is fixedly mounted on the handle and moves with the handle;
[0008] A limiting track is provided laterally at the bottom of the top cover;
[0009] The slide block is slidably disposed within the limiting track, and the sliding direction of the slide block intersects with the movement direction of the fixed block, so that the stop block blocks the movement direction of the fixed block; the top cover is provided with a clearance hole for the actuating block to pass through.
[0010] As a further optional solution, the limiting track includes a baffle and a claw, the baffle and the claw being spaced apart at the bottom of the top cover, the claw engaging with one side edge of the slide, the slide being disposed between the baffle and the claw; according to the movement direction of the fixed block, the baffle is disposed on the side of the block away from the fixed block.
[0011] As a further optional solution, the baffle includes a first side surface, the claw includes a second side surface, the first side surface and the second side surface respectively abut against the two sides of the slide, and a buckle block is protruding on the second side surface of the claw.
[0012] As a further optional solution, the baffle is provided with a plurality of first reinforcing ribs on the side away from the slide, and the claw is provided with a second reinforcing rib on the side away from the slide.
[0013] As a further optional solution, limit plates are provided at both ends of the limiting track.
[0014] As a further optional solution, the height of the baffle is equal to the sum of the heights of the slide and the stop.
[0015] As a further alternative, the stop block is shaped like a C-shaped column.
[0016] As a further optional solution, multiple stops are provided, and the number of fixed blocks corresponds to the number of stops.
[0017] Compared with the prior art, the oil sprayer of this application has at least the following advantages:
[0018] This fuel injector features a movable lever that can be tossed left and right, enabling a single-step switching between locked and unlocked states, thus improving ease of operation. In the locked state, the stop block on the locking component and the fixed block form a rigid barrier, while the limiting rail provides structural support for the locking component. The limiting rail is located at the bottom of the top cover, allowing the top cover to withstand the force. Even if the handle is subjected to a large external force (such as accidental pressing or accidental activation by a child), the strong pressure will not cause the fixed block to push open the stop block, and the stop block will not break, thus improving the stability of the locking structure.

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0033] refer to Figure 1-6 An embodiment of this utility model shows an oil sprayer, including an oil reservoir 1, a pump body 2 disposed on the oil reservoir 1, a nozzle 3 connected to the pump body 2, and a handle 4 for triggering the pump body 2. The oil reservoir 1 is provided with a protective cover 5 covering the pump body 2 and the nozzle 3. The protective cover 5 includes a top cover 51; it also includes a locking mechanism 6.
[0034] The locking mechanism 6 includes a locking member 61, a fixing block 62, and a limiting track 63. The locking member 61 includes a slide 611, a stop block 613 disposed at the bottom of the slide 611, and a toggle block 612 disposed at the top of the slide 611. The fixing block 62 is fixedly disposed on the handle 4 and moves with the handle 4. The limiting track 63 is disposed laterally at the bottom of the top cover 51. The slide 611 is slidably disposed within the limiting track 63, and the sliding direction of the slide 611 intersects the movement direction of the fixing block 62, so that the stop block 613 blocks the movement direction of the fixing block 62. The top cover 51 has an avoidance hole 511 for the toggle block 612 to pass through.
[0035] Specifically, such as Figure 4-6 As shown, the locking member 61 can move laterally along the limiting track 63 to block the fixing block 62 with the stop 613, or to offset the stop 613 from the fixing block 62. Clearly, when the stop 613 blocks the fixing block 62, the structural interference between the stop 613 and the fixing block 62 prevents the handle 4 from being pressed down, thus achieving locking. When the stop 613 is offset from the fixing block 62, the fixing block 62 can move, and the handle 4 can be pressed down, thus achieving unlocking. Moving the locking member 61 only requires moving the actuating block 612, making operation convenient.
[0036] The limiting track 63 provides structural support for the locking member 61. The limiting track 63 is located on the top of the top cover 51. When the handle 4 is subjected to a large external force (such as accidental pressing or accidental touch by a child), the locking member 61 is subjected to pressure load from the fixing block 62. The load can be distributed to the limiting track 63 and the top cover 51, preventing the stop block 613 on the locking member 61 from breaking. Furthermore, the locking member 61 is not easy to loosen and will not be blocked by the fixing block 62, resulting in high structural stability.
[0037] In some embodiments, to further ensure that the limiting track 63 provides sufficient structural support for the locking member 61, such as Figure 4-6 As shown, the limiting track 63 includes a baffle 631 and a claw 632. The baffle 631 and the claw 632 are spaced apart at the bottom of the top cover 51. The claw 632 engages with one side edge of the slide block 611. The slide block 611 is located between the baffle 631 and the claw 632. According to the movement direction of the fixing block 62, the baffle 631 is located on the side of the stop block 613 away from the fixing block 62.
[0038] In this embodiment, the locking member 61 is not easily disengaged from the limiting track 63 by the latch 632 engaging with the slide 611, ensuring that the locking member 61 can only move along the preset trajectory. Specifically, the baffle 631 blocks the sides of the slide 611 and the stop block 613. In this embodiment, the height of the baffle 631 is equal to the sum of the heights of the slide 611 and the stop block 613. Thus, when the fixing block 62 presses against the stop block 613, the stop block 613 transfers the load to the baffle 631, and the baffle 631 can transfer the load to the top cover 51, thereby dispersing the load and preventing the stop block 613 from breaking due to excessive positional stress.
[0039] In this embodiment, as Figure 4 and Figure 6 As shown, the baffle 631 includes a first side surface 6311, and the claw 632 includes a second side surface 6321. The first side surface 6311 and the second side surface 6321 respectively abut against the two sides of the slide block 611. A latching block 6323 protrudes from the second side surface 6321 of the claw 632. There is friction between the first side surface 6311 and the slide block 611, and there is also friction between the second side surface 6321 and the slide block 611. That is, the baffle 631 and the claw 632 clamp the slide block 611 to a certain extent, so that the locking member 61 requires a certain external force to move, thus preventing the locking member 61 from easily loosening or accidentally unlocking due to the squeezing of the fixing block 62 or other reasons.
[0040] In this embodiment, as Figure 4 and Figure 6As shown, the baffle 631 has multiple first reinforcing ribs 6312 on the side away from the slide block 611, and the claw 632 has a second reinforcing rib 6322 on the side away from the slide block 611. Thus, the first reinforcing ribs 6312 and the second reinforcing ribs 6322 strengthen the structure of the baffle 631 and the claw 632, preventing them from breaking.
[0041] In some embodiments, such as Figure 4 As shown, limit plates 633 are respectively provided at both ends of the limiting track 63. In this embodiment, rapid positioning is achieved by using two limit plates 633; for example, when the slide 611 abuts against one limit plate 633, it means that the stop 613 blocks the fixing block 62; when the slide 611 abuts against the other limit plate 633, it means that the stop 613 and the fixing block 62 are misaligned.
[0042] In some embodiments, such as Figure 5 As shown, the stop block 613 is a prism with a C-shaped cross-section. This gives the stop block 613 sufficient structural strength, making it less prone to breakage, and its hollow structure reduces the amount of material used.
[0043] Specifically, the above solution includes multiple stop blocks 613, and the number of fixing blocks 62 corresponds to the number of stop blocks 613, thereby further increasing the structural strength. In this embodiment, there are two stop blocks 613 and two fixing blocks 62.
[0044] In summary, this application provides an oil sprayer that achieves a single-step switching between locked and unlocked states by setting a movable toggle block 612, which improves the ease of operation. In the locked state, the stop block 613 on the locking member 61 and the fixing block 62 form a rigid block, while the limiting rail 63 provides structural support for the locking member 61. The limiting rail 63 is located at the bottom of the top cover 51, so that the top cover 51 can bear the force. Even if the handle 4 is subjected to a large external force (such as accidental pressing or accidental touch by a child), the strong pressure will not cause the fixing block 62 to push open the stop block 613, and the stop block 613 will not break, thus improving the stability of the locking structure.
[0045] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
