Description

Technical Field

[0001] This application relates to the field of spray can technology, and in particular to a cleaning agent spray can device with replaceable nozzles. Background Technology

[0002] In the modern cleaning industry, cleaning agent spray cans are commonly used tools in various scenarios such as home cleaning, car maintenance, and industrial equipment cleaning. With the increasing sophistication of users' cleaning needs, spray can devices with replaceable nozzles are becoming an industry trend due to their ability to adapt to different spray patterns (such as fan spray, concentrated spray, and foam output). However, existing cleaning agent spray can devices with replaceable nozzles generally suffer from serious functional defects.

[0003] In practical use, it has been found that most spray can devices on the market currently lack liquid dispensing control functions. During nozzle replacement, the cleaning agent leaks in large quantities from the connection between the can and the nozzle due to the internal pressure of the spray can. When disassembling the nozzle of a traditional spray can, the cleaning agent easily overflows directly from the top of the suction tube, which not only wastes materials but also may cause residual liquid to corrode surrounding items and pollute the environment. If the sprayed cleaning agent is corrosive, it may also cause damage to the user's skin and clothing. Therefore, we have proposed a cleaning agent spray can device with a replaceable nozzle to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies, such as the tendency of cleaning agent to overflow directly from the tip of the suction tube when the nozzle is disassembled, which not only wastes materials but also may cause residual liquid to corrode surrounding items and pollute the environment. Therefore, this application proposes a cleaning agent spray can device with a replaceable nozzle.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a cleaning agent spray can device with replaceable nozzles, comprising a spray can, a connecting seat fixedly installed on the top of the spray can, a nozzle disposed above the connecting seat, a positioning mechanism and a snap-fit ​​mechanism disposed between the nozzle and the connecting seat, a suction tube fixedly installed inside the connecting seat, the top end of the suction tube being adapted to the nozzle, the bottom end of the suction tube extending into the spray can, and a movable cavity and a functional cavity being provided inside the connecting seat; a limit mechanism is provided inside the movable cavity, a liquid dispensing control mechanism is provided between the functional cavity and the suction tube, and a reset mechanism is provided inside the functional cavity.

[0006] A further feature of this application is that the positioning mechanism includes a positioning seat and a positioning block. The positioning seat is fixedly installed on the top of the connecting seat, and a groove is provided on the inner side of the positioning seat. Positioning blocks are fixedly installed on both sides of the nozzle, and the positioning blocks are engaged with the groove.

[0007] By adopting the above technical solution and setting a positioning mechanism, the positioning block can be inserted into the groove of the positioning seat, so as to achieve precise alignment between the nozzle and the connecting seat and avoid poor sealing or functional failure caused by installation misalignment.

[0008] A further configuration of this application is as follows: the snap-fit ​​mechanism includes a snap-fit ​​ring and an annular groove. The snap-fit ​​ring is fixedly installed at the bottom of the nozzle. An annular groove is provided on the top of the connecting seat. The annular groove is located inside the positioning seat and the movable cavity. The functional cavity is located below the annular groove. The snap-fit ​​ring snaps into the annular groove. Rod grooves are provided on both sides of the snap-fit ​​ring.

[0009] By adopting the above technical solution and by setting a snap-fit ​​mechanism, the snap-fit ​​ring can gradually enter the annular groove, thereby achieving the purpose of forming a sealed connection between the nozzle and the connecting seat.

[0010] A further configuration of this application is as follows: the limiting mechanism includes a slider, a limiting rod, and a first spring. The slider is slidably installed in the movable cavity, and the limiting rod is fixedly installed on the outside of the slider. One end of the limiting rod extends to the outside of the connecting seat, and the other end of the limiting rod extends into the annular groove. The first spring is sleeved on the limiting rod. The two ends of the first spring are fixedly connected to the outside of the slider and the inner wall of the movable cavity away from the annular groove, respectively. The other end of the limiting rod is engaged with the rod groove, and a pull button is fixedly installed on one end of the limiting rod.

[0011] By adopting the above technical solution and setting a limiting mechanism, the limiting rod can be disengaged from or engaged with the rod groove by pulling or releasing the button and the rebound force of the first spring, thereby achieving the purpose of installing and fixing the nozzle and the connecting seat or releasing the limiting mechanism.

[0012] A further configuration of this application is as follows: the reset mechanism includes a reset plate, a push rod, and an annular sliding plate. The reset plate is slidably installed in the functional cavity, and the push rod is fixedly installed on the top of the reset plate. The top end of the push rod extends into the annular groove, and the annular sliding plate is fixedly installed on the top end of the push rod. The annular sliding plate is slidably connected to the inner wall of the annular groove, and the bottom of the snap ring is adapted to the top of the annular sliding plate.

[0013] By adopting the above technical solution and by setting a reset mechanism, the reset force of the second spring can push the reset plate to move upward, and the valve plate can be returned to its original position through the reverse transmission of the rack plate and the gear.

[0014] A further feature of this application is that the liquid dispensing control mechanism includes a valve plate and a rotating rod. The same valve plate is rotatably installed on the inner walls of both sides of the suction tube, and a rotating rod is rotatably installed on the inner wall of the right side of the functional cavity. The left end of the rotating rod is fixedly connected to the right side of the valve plate, and a gear mechanism is provided between the rotating rod and the reset plate.

[0015] By adopting the above technical solution and by setting up a liquid dispensing control mechanism, the rotating rod can drive the valve plate to rotate, thereby achieving the purpose of closing or opening the suction tube through the valve plate.

[0016] A further feature of this application is that the gear mechanism includes a rack and a gear, a rack is fixedly installed on the bottom of the reset plate, a gear is fixedly sleeved on the rotating rod, the gear is located in the functional cavity, and the gear meshes with the rack.

[0017] By adopting the above technical solution and by setting a gear mechanism, the reset plate can drive the rotating rod to rotate.

[0018] A further feature of this application is that a second spring is sleeved on the push rod, and the two ends of the second spring are fixedly connected to the inner wall of the top of the functional cavity and the top of the reset plate, respectively.

[0019] By adopting the above technical solution, and by setting a second spring, the second spring can drive the reset plate and the rack plate to move upward and reset through the rebound force.

[0020] The beneficial effects of this application are:

[0021] (1) By the cooperation of the pull button, the limiting rod, the slider and the first spring, the pull button and the rebound force of the first spring can drive the limiting rod to disengage or engage with the rod groove, so as to achieve the purpose of convenient disassembly and assembly of the nozzle and the connecting seat.

[0022] (2) By using the snap ring, ring slide, push rod, reset plate, second spring, rack plate, gear, rotating rod and valve plate, when the nozzle is disassembled, the reset force of the second spring pushes the reset plate to move up, and the valve plate returns to its original position through the reverse transmission of the rack plate and gear. This can quickly close the suction pipe channel and prevent the cleaning agent in the spray can from leaking due to internal pressure. In this way, it can avoid liquid leakage during replacement and improve the safety and ease of operation of the device. Attached Figure Description

[0033] Specifically, the limiting mechanism includes a slider 501, a limiting rod 502, and a first spring 503. The slider 501 is slidably installed in the movable cavity 5. The limiting rod 502 is fixedly installed on the outside of the slider 501. One end of the limiting rod 502 extends to the outside of the connecting seat 2, and the other end of the limiting rod 502 extends into the annular groove 201. The first spring 503 is sleeved on the limiting rod 502. Both ends of the first spring 503 are fixedly connected to the outside of the slider 501 and the inner wall of the movable cavity 5 away from the annular groove 201, respectively. The other end of the limiting rod 502 is engaged with the rod groove 302. A pull button 504 is fixedly installed on one end of the limiting rod 502.

[0034] Specifically, the reset mechanism includes a reset plate 602, a push rod 601, and an annular slide plate 6. The reset plate 602 is slidably installed in the functional cavity 7. The push rod 601 is fixedly installed on the top of the reset plate 602. The top end of the push rod 601 extends into the annular groove 201. The annular slide plate 6 is fixedly installed on the top end of the push rod 601. The annular slide plate 6 is slidably connected to the inner wall of the annular groove 201. The bottom of the snap ring 301 is adapted to the top of the annular slide plate 6.

[0035] Specifically, the liquid dispensing control mechanism includes a valve plate 801 and a rotating rod 802. The same valve plate 801 is rotatably installed on the inner walls of both sides of the suction tube 8. The rotating rod 802 is rotatably installed on the inner wall of the right side of the functional cavity 7. The left end of the rotating rod 802 is fixedly connected to the right side of the valve plate 801. A gear mechanism is provided between the rotating rod 802 and the reset plate 602.

[0036] Specifically, the gear mechanism includes a rack plate 9 and a gear 901. The rack plate 9 is fixedly installed at the bottom of the reset plate 602, and the gear 901 is fixedly sleeved on the rotating rod 802. The gear 901 is located in the functional cavity 7 and meshes with the rack plate 9.

[0037] Specifically, a second spring 603 is sleeved on the push rod 601, and the two ends of the second spring 603 are fixedly connected to the top inner wall of the functional cavity 7 and the top of the reset plate 602, respectively.

[0038] In this application, when installing the nozzle 3, the positioning block 401 is first inserted into the groove of the positioning seat 4 to achieve precise alignment between the nozzle 3 and the connecting seat 2, thus avoiding poor sealing or functional failure caused by installation misalignment. The nozzle 3 is then pressed down further, causing the retaining ring 301 to gradually enter the annular groove 201, while simultaneously squeezing the annular sliding plate 6 to move downwards. The annular sliding plate 6, through the push rod 601, drives the reset plate 602 to compress the second spring 603 and move downwards within the functional cavity 7. During this process, the rack plate 9 at the bottom of the reset plate 602 meshes with the gear 901 for transmission. The drive rod 802 drives the valve plate 801 to rotate, switching the suction tube 8 channel from the closed state to the open state, thus providing a path for the cleaning agent to flow. When the locking ring 301 is fully engaged in the annular groove 201, the limiting rod 502 automatically springs into the rod groove 302 under the elastic force of the first spring 503, which can securely fix the nozzle 3 to the connecting seat 2, ensuring that the nozzle 3 will not loosen or fall off during high-pressure spraying. At this time, the suction tube 8 is connected to the nozzle 3, and pressing the nozzle 3 can achieve a stable spraying of the cleaning agent to meet the cleaning requirements.

[0039] When disassembling the nozzle 3, pulling the button 504 outward causes the limiting rod 502 to compress the first spring 503 along with the slider 501 and disengage from the rod groove 302, thus releasing the limiting force on the locking ring 301. The reset force of the second spring 603 pushes the reset plate 602 upward, and through the reverse transmission of the rack plate 9 and the gear 901, the valve plate 801 returns to its original position, which can quickly close the suction pipe 8 channel and prevent the cleaning agent in the spray can 1 from leaking due to internal pressure. At the same time, the reset plate 602 drives the annular slide plate 6 upward through the push rod 601, generating an upward pushing force on the locking ring 301, assisting the nozzle 3 to disengage from the annular groove 201, making disassembly easier and ultimately achieving the purpose of quick replacement of the nozzle 3. This also avoids liquid leakage during replacement, improving the safety and ease of operation of the device.
