Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically a portable sprayer. Background Technology

[0002] Press-type sprayers are a common type of spraying equipment in our daily lives. They can spray liquids evenly in the form of a mist through a simple pressing operation. Press-type sprayers are mainly composed of components such as nozzles, press pumps, liquid storage bottles, and suction tubes.

[0003] When using a sprayer, the sprayer atomizes the liquid into fine water droplets and sprays them out. After the atomized water droplets are sprayed out, some of the water droplets remain on the inner wall of the sprayer nozzle. After a period of time, the water droplets on the inner wall of the nozzle will gather due to gravity and other factors, and eventually drip out of the sprayer nozzle, causing pollution to the working environment. To address this, a portable sprayer is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a portable sprayer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable sprayer, comprising a sprayer body, and further comprising:

[0006] A leak-proof component, which is located at the nozzle of the sprayer body, is used to prevent liquid from dripping from the nozzle of the sprayer body.

[0007] The leak-proof component includes a threaded cap that is threadedly connected to the nozzle of the sprayer body. A spray hole is formed in the center of the threaded cap, and two sets of movable rings are rotatably connected to the inner wall of the spray hole. A groove is formed inside the threaded cap, and an arc-shaped component is fixed inside the groove. A connector is fixed to the outer surface of the movable rings. A spring plate is embedded at the end of the connector, and a button is fixed to the outer end of the spring plate. A slot is formed inside the button. A protrusion is fixed to the outside of the threaded cap. A sliding groove is formed inside the connector, and a fixed shaft is fixed inside the sliding groove. A movable shaft and a return spring are fitted onto the outer surface of the fixed shaft. A connecting frame is fixed to the center of the movable shaft, and a sealing element is fixed to one end of the connecting frame.

[0008] As described above, the seal is located between the two sets of movable rings, and the movable rings are in contact with the surface of the seal.

[0009] As mentioned above, the contact surface between the movable ring and the seal is bonded with rubber.

[0010] As described above, the arc-shaped component is in contact with the return spring, and the return spring is elastically supported between the slide groove and the movable shaft.

[0011] As described above, the end of the connector passes through the slot and is slidably connected to the slot.

[0012] As described above, the slot and the protrusion are engaged in a movable engagement, and when the protrusion and the slot are engaged, the seal is located in the middle of the movable ring.

[0013] Compared with existing technologies, this portable sprayer has the following advantages:

[0014] I. This utility model allows the connector to slide along the inner wall of the groove through the cooperation between the connector and the groove, thereby causing the movable shaft to be squeezed against the arc-shaped part. At the same time, through the cooperation between the movable shaft and the fixed shaft, the movable shaft will slide along the outer surface of the fixed shaft, and the sealing part will be embedded between the two sets of movable rings, thereby sealing the spray hole and preventing liquid leakage.

[0015] II. This utility model uses the elasticity of the spring sheet to drive the slot and the protrusion to engage and position the connecting part, thereby enabling the seal to stably close the movable ring. The slot and the protrusion can be separated by pressing the button. At this time, the elasticity of the return spring will drive the movable shaft and the arc-shaped part to squeeze, thus facilitating the separation of the seal and the movable ring and facilitating the opening or closing of the spray hole.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-6 As shown, this utility model provides a portable sprayer, including a sprayer body 1, and further comprising:

[0026] A leak-proof component is provided at the nozzle of the sprayer body 1 to prevent liquid from dripping from the nozzle of the sprayer body 1.

[0027] The leak-proof component includes a threaded cap 2, which is threadedly connected to the nozzle of the sprayer body 1. A spray hole 3 is provided in the middle of the threaded cap 2. Two sets of movable rings 4 are rotatably connected to the inner wall of the spray hole 3. A groove 5 is provided inside the threaded cap 2. An arc-shaped part 6 is fixed inside the groove 5. A connector 7 is fixed to the outer surface of the movable ring 4. A spring plate 9 is embedded at the end of the connector 7. A button 10 is fixed to the outer end of the spring plate 9. A slot 11 is provided inside the button 10. A protrusion 12 is fixed to the outside of the threaded cap 2. A sliding groove 8 is provided inside the connector 7. A fixed shaft 13 is fixed inside the sliding groove 8. A movable shaft 14 and a return spring 15 are sleeved on the outer surface of the fixed shaft 13. A connecting frame 16 is fixed in the middle of the movable shaft 14. A sealing element 17 is fixed to one end of the connecting frame 16.

[0028] The connection between the connector 7 and the groove 5 allows the connector 7 to slide along the inner wall of the groove 5, thereby causing the movable shaft 14 to be squeezed against the arc-shaped part 6. At the same time, the connection between the movable shaft 14 and the fixed shaft 13 causes the movable shaft 14 to slide along the outer surface of the fixed shaft 13, and causes the sealing part 17 to be embedded between the two sets of movable rings 4, thereby sealing the movable rings 4 and preventing liquid leakage.

[0029] like Figure 3 , 6 As shown, the seal 17 is located between the two sets of movable rings 4, and the movable rings 4 are in contact with the surface of the seal 17.

[0030] Through the cooperation between the seal 17 and the movable ring 4, the seal 17 can be embedded between the two sets of movable rings 4 when it moves, thereby sealing the nozzle 3.

[0031] like Figure 6 As shown, the contact surface between the movable ring 4 and the seal 17 is bonded with rubber.

[0032] The rubber provided on the contact surface between the movable ring 4 and the seal 17 can improve the sealing performance between them and further prevent liquid leakage.

[0033] like Figure 6 As shown, the arc-shaped part 6 is in contact with the return spring 15, and the return spring 15 is elastically supported between the slide groove 8 and the movable shaft 14.

[0034] The design of the return spring 15 enables the movable shaft 14 to have good elastic return performance. Since the return spring 15 is in a compressed state, it will apply an elastic force to the movable shaft 14, thereby enabling the seal 17 to be separated from the movable ring 4 through the connecting bracket 16, which facilitates the opening of the spray hole 3.

[0035] like Figure 4 , 5 As shown, the slot 11 and the protrusion 12 are engaged in a movable engagement. When the protrusion 12 and the slot 11 are engaged, the seal 17 is located in the middle of the movable ring 4, and the end of the connector 7 passes through the slot 5 and is slidably connected to the slot 5.

[0036] The spring force of the spring plate 9 will cause one end of the button 10 to move downward. Through the cooperation between the slot 11 and the protrusion 12, the button 10 can be used to position the connector 7, thereby enabling the seal 17 to stably seal the movable ring 4. Pressing the button 10 can also cause the slot 11 and the protrusion 12 to separate, making it easier for the reset spring 15 to drive the movable shaft 14 to squeeze the arc-shaped part 6, and quickly control the connector 7 to reset.

[0037] Working principle:

[0038] After using the sprayer body 1, the user can press and push the button 10 to rotate. At this time, through the cooperation between the connector 7 and the slot 5, the connector 7 can slide along the inner wall of the slot 5, thereby causing the movable shaft 14 to be squeezed against the arc-shaped part 6. At the same time, through the cooperation between the movable shaft 14 and the fixed shaft 13, the movable shaft 14 will slide along the outer surface of the fixed shaft 13, and the seal 17 will be inserted between the two sets of movable rings 4. Then, the button 10 is released, and the elasticity of the spring plate 9 supports one side of the button 10. At this time, the slot 11 will engage with the protrusion 12, which makes it easy for the seal 17 to seal the spray hole 3 and prevent liquid leakage.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
