Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to a spray gun structure and a spray bottle. Background Technology

[0002] Currently, when the nozzle on a spray bottle needs to be adjusted in length, it is necessary to switch between long and short nozzles, or to install a telescopic nozzle on the outside of the spray bottle. However, the telescopic nozzle is exposed and has a relatively long length, making it inconvenient to store and easy to damage. Utility Model Content

[0003] To address the problem of inconvenient nozzle length adjustment, this invention provides a spray gun structure and a spray bottle.

[0004] The technical solution of this utility model is as follows:

[0005] On the one hand, this utility model provides a spray gun structure, characterized in that it includes:

[0006] The gun body has a receiving cavity provided inside it along the extension direction of the gun body;

[0007] A nozzle is disposed at the opening end of the receiving cavity;

[0008] A nozzle, connected to and communicating with the nozzle and extendable, is disposed within the receiving cavity;

[0009] A locking assembly is used to lock the position of the nozzle after it extends out of the receiving cavity.

[0010] Furthermore, the nozzle includes multiple layers of telescopic tubes, with the extended end of the telescopic tube connected to and communicating with the nozzle, and the other end of the telescopic tube connected to and communicating with the liquid inlet assembly.

[0011] Furthermore, the nozzle includes a universal shaped hose that can be pulled out or retracted into the receiving cavity.

[0012] Furthermore, the locking assembly is configured as an internally through-hole locking chuck assembly, the nozzle is movably inserted into the locking chuck assembly and its end is connected to and communicates with the nozzle, and the maximum diameter of the nozzle is greater than the inner diameter of the internal through-hole of the locking chuck assembly.

[0013] Furthermore, the locking chuck assembly includes an externally threaded pipe section, one end of which facing the nozzle has a tapered head. The tapered head has a radial groove along its small end sidewall. An internally threaded tapered sleeve is fitted on the outside of the externally threaded pipe section. The internally threaded tapered sleeve is adapted to control the tapered head to deform along its axial direction.

[0014] Furthermore, the receiving cavity is configured as a guide channel, and the nozzle is slidably connected to the guide channel.

[0015] Furthermore, the liquid inlet assembly includes a liquid inlet pipe, which is connected to the nozzle via a pipe connector assembly.

[0016] Furthermore, the inlet pipe has a coiled section within the gun body for the nozzle to extend or retract from the receiving cavity;

[0017] And / or, a spring is sleeved on the outside of the inlet pipe;

[0018] And / or, springs are fitted on the outer side of each bend of the inlet pipe.

[0019] Furthermore, it also includes a grip located at the end of the gun body away from the nozzle, and a power module is provided inside the grip. The control board is installed between the grip and the receiving cavity, and a switch is provided on the control board that protrudes outside the gun body.

[0020] According to another aspect of the present invention, a spray bottle is also provided, including the spray gun structure as described above, and further including a bottle body and a pump body. The gun body includes a bottle mouth connection part, which is connected to the bottle body and the pump body is installed thereon. The pump body is connected to the inside of the bottle body through a liquid extraction pipe, and the pump body supplies liquid to the spray pipe.

[0021] The beneficial effects achieved by this utility model are as follows:

[0022] The spray gun structure of this utility model includes a gun body, in which a receiving cavity is provided along the extension direction of the gun body; a nozzle is provided at the open end of the receiving cavity; a spray pipe is provided that can extend out of the receiving cavity, and the spray pipe is connected to and communicates with the nozzle; it also includes a locking component, which can be used to lock the position of the spray pipe after it extends out of the receiving cavity.

[0023] The gun body has a receiving cavity for housing the nozzle, which connects to the nozzle and can extend or retract into the receiving cavity. Since the receiving cavity is located along the extension direction of the gun body, the nozzle can move along the same direction. When a longer nozzle is needed, it can be pulled out of the gun body to a specified length via the nozzle, and then locked in that position by a locking assembly to ensure stable use. When only a short nozzle is needed or when it needs to be stored, the locking assembly can be released to retract the nozzle into the receiving cavity. By housing the nozzle within the receiving cavity of the gun body, the nozzle can be extended or retracted according to the usage scenario while ensuring that the length of the nozzle exposed outside the gun body is not too long. This design results in a compact size and structure, while also protecting the nozzle itself. Attached Figure Description

[0038] In a first aspect, this application discloses a spray gun structure, including a gun body 100, in which a receiving cavity 110 is provided along the extension direction of the gun body 100; a nozzle 200 is provided at the open end of the receiving cavity 110; a spray pipe 300 is provided extendably in the receiving cavity 110, and the spray pipe 300 is connected to and communicates with the nozzle 200; and a locking component is also included, which can be used to lock the position of the spray pipe 300 after it extends out of the receiving cavity 110.

[0039] In this embodiment, the receiving cavity 110 in the gun body 100 is used to accommodate the nozzle 300. The nozzle 300 is connected to the nozzle 200 and can extend or retract into the receiving cavity 110. Since the receiving cavity 110 is arranged along the extension direction of the gun body 100, the nozzle 300 can move along the extension direction of the gun body 100. When a longer nozzle 300 is required, the nozzle 300 can be pulled out of the gun body 100 to a specified length through the nozzle 200, and then the position of the nozzle 300 can be locked by the locking assembly. The locking mechanism ensures stable use. When only the short nozzle is needed or when it needs to be stored, the locking component can be released to retract the nozzle 300 into the receiving cavity 110. The receiving cavity 110 inside the gun body 100 accommodates the nozzle 300, allowing it to extend or retract in length according to the usage scenario while ensuring that the length of the nozzle 200 protruding from the gun body 100 is not too long. It is compact in size and structure, and also provides protection for the nozzle 300 itself.

[0040] In an optional or preferred embodiment, the nozzle 300 includes a telescopic tube with multiple inner and outer layers. The extended end of the telescopic tube is connected to and communicates with the nozzle 200, and the other end of the telescopic tube is connected to and communicates with the liquid inlet assembly 500. When the nozzle 200 needs to extend, the nozzle 200 drives the nozzle 300 to extend to the open end of the receiving cavity 110. The inner and outer layers can be understood as two or more layers, including but not limited to 2 layers, 3 layers, 4 layers, etc., which can be selected according to actual needs.

[0041] In an optional or preferred embodiment, the nozzle 300 includes a universal shaping hose that can be pulled out or retracted into the receiving cavity 110. The universal shaping hose can be pulled out of the open end of the receiving cavity 110 to extend. At the same time, the universal shaping hose can also be hovered at any angle and position and maintain that position, i.e., shaped, so as to meet the usage needs of different scenarios.

[0042] In an optional or preferred embodiment, the nozzle 300 may also be a combination of a telescopic tube and a universal shaping hose, for example, the universal shaping hose is first connected to the extended end of the telescopic tube and then connected to the nozzle.

[0043] In an optional or preferred embodiment, the locking assembly is configured as a locking chuck assembly 400 with an internal through-hole design. The nozzle 300 is movably inserted into the locking chuck assembly 400 and its end is connected to and communicates with the nozzle 200. The maximum diameter of the nozzle 200 is greater than the inner diameter of the internal through-hole of the locking chuck assembly 400.

[0044] In this embodiment, the nozzle 300 is movably disposed on the locking chuck assembly 400, so that after the nozzle 300 passes through the locking chuck assembly 400 and extends to a specified length, the locking chuck assembly 400 can lock the nozzle 300. Since the maximum diameter of the nozzle 200 is greater than the inner diameter of the through hole of the locking chuck assembly 400, the nozzle 200 can be prevented from moving into the receiving cavity 110.

[0045] In an optional or preferred embodiment, the locking clamp assembly 400 includes an externally threaded pipe section 410, with a tapered head 420 at one end facing the nozzle 200. The tapered head 420 has a radially slotted sidewall at its small end. An internally threaded tapered sleeve 430 is fitted over the externally threaded pipe section 410, which is adapted to control the axial deformation of the tapered head 420. The nozzle 300 is movably inserted inside the externally threaded pipe section 410. The tapered head 420 has a slot, which allows the sheet-like body between the two slots to have good deformation capability. By tightening the internally threaded tapered sleeve 430, the end of the tapered head 420 can be compressed in the axial direction, thereby providing a locking force to the nozzle 300 inside.

[0046] In an optional or preferred embodiment, the receiving cavity 110 is configured as a guide channel, and the nozzle 300 is slidably connected to the guide channel. The nozzle 300 is guided to move through the guide channel, which can ensure the stability of the nozzle 300 during use.

[0047] In an optional or preferred embodiment, the liquid inlet assembly 500 includes a liquid inlet pipe 510, which is connected to the nozzle 300 via a pipe fitting assembly 520.

[0048] In an optional or preferred embodiment, the inlet tube 510 has a winding section within the gun body 100 for the nozzle 300 to extend or retract from the receiving cavity 110. The inlet tube 510 has a winding section that allows the nozzle 300 to be pulled out or pulled back out of the receiving cavity 110 for a longer period.

[0049] In an optional or preferred embodiment, a spring is fitted around the outside of the inlet pipe 510 to prevent deformation of the flexible material inlet pipe 510 from causing obstruction of the water flow. In an optional or preferred embodiment, springs are fitted around the outside of each bend of the inlet pipe 510 to prevent the inlet pipe 510 from bending or deforming.

[0050] In an optional or preferred embodiment, the device further includes a grip 120 located at the end of the gun body 100 away from the nozzle 200. A power module 610 is disposed within the grip 120. A control board 620 is installed between the grip 120 and the receiving cavity 110. Switches on the control board 620 protrude from the gun body 100. Holding the gun with the grip 120 improves user comfort. The power module 610, disposed within the grip 120, makes efficient use of its space and contributes to miniaturization. The power module 610 can be a battery. The control board 130 is used to control various electrical components, such as the battery and the pump. The switches on the control board 620 protruding from the gun body 100 facilitate user grip while enabling the switching to be turned on and off.

[0051] On the other hand, this application also discloses a spray bottle, including the spray gun structure described above, and further including a bottle body 530 and a pump body 540. The gun body 100 includes a bottle mouth connection portion 130, which is connected to the bottle body 530 and where the pump body 540 is installed. The pump body 540 is connected to the inside of the bottle body 530 through a liquid extraction pipe 550, and the pump body 540 supplies liquid to the spray pipe 300. The liquid is stored in the bottle body 530, for example, by opening the screw cap on the bottle body 530 to fill it, and then the pump body 540 is started to draw the liquid in the bottle body 530 to the spray pipe 300, and finally sprayed out from the nozzle 200.

[0052] Furthermore, the kettle body 530 is provided with an air inlet channel that can connect to the outside, preventing the kettle body 530 from being flattened by atmospheric pressure after the liquid inside the kettle body 530 is drawn out; preferably, the aperture of the air inlet channel is designed to be small, which can prevent the liquid from flowing out when the kettle body 530 is tilted under the action of liquid surface tension.
