Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a lightweight spray gun. Background Technology

[0002] The water jet from a spray gun has a strong scouring force, making it widely applicable. Currently, most spray guns on the market use a push-button switch structure, including a button and a switching valve. The switching valve is activated by pressing the button. However, many existing spray guns suffer from difficult switching due to water pressure issues, causing users to exert considerable effort when pressing the button. Therefore, this invention provides a spray gun structure that is simple in design and more convenient to use, solving the aforementioned technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a spray gun structure that is relatively lightweight.

[0004] A lightweight spray gun includes a spray gun body and a switching assembly.

[0005] The spray gun body includes a handle and a water outlet. The handle has a water inlet channel and a mounting cavity, and a clearance opening is provided around the handle to connect with it. A telescopic port is provided between the water inlet channel and the water inlet end of the mounting cavity, and the water outlet end of the mounting cavity is provided with a water outlet seat. The water outlet seat has a coupling interface that is opposite to and coaxial with the telescopic port, and a water passage hole communicating with the water outlet is provided in the coupling interface.

[0006] The switching assembly includes a switching tube, an elastic element, and an operating element. The inlet end of the switching tube is telescopically installed inside the telescopic port and connects to the inlet channel. The outlet end of the switching tube is telescopically inserted into the connecting port and offset from the water passage hole. The periphery of the switching tube is sealed to both the telescopic port and the connecting port to prevent water leakage to the outer periphery of the switching tube. The elastic element is located between the switching tube and the handle, and pushes the outlet end of the switching tube tightly against the end of the connecting port when the water is turned off, forming a seal. The operating element is movably installed at the clearance opening of the handle and is linked to the switching tube. The switching tube retracts from the connecting port through the switching action of the operating element, opening the outlet end of the switching tube and allowing the switching tube to connect to the water passage hole, thus opening the spray gun.

[0007] The spray gun provided by this utility model has a telescopic tube-type switching structure for its switching component. When water is flowing, the area of ​​the water inlet end of the switching shaft submerged in water is very small. Therefore, the water pressure on the switching shaft is very small when it moves telescopically, making the spray gun lighter and easier to use, and providing a better user experience. In addition, the spray gun switching structure provided by this utility model is simple and easy to manufacture and assemble.

[0008] Preferably, the outer periphery of the switching tube is provided with an annular linkage groove, and the operating component is oscillatingly or slidingly mounted on the handle, and is provided with a linkage block extending to the outer periphery of the switching tube. The linkage block is located in the annular linkage groove. When water needs to be discharged, the operating component is pressed or pushed, and the operating component rotates or moves and drives the switching tube to move axially.

[0009] Preferably, the elastic element is a spring tube, which is compressed and sleeved on the outer periphery of the switching tube. One end abuts against the end of the telescopic port facing the mounting cavity, and the other end abuts against the annular protrusion on the outer periphery of the switching tube. The structure is simple and provides uniform restoring force.

[0010] Preferably, the cross-section of the outlet end of the switching pipe is larger than the cross-section of the inlet end, so that when the water is flowing out, the water force on the outlet end of the switching pipe is greater, which can further offset the elastic force of the elastic element, so that the user does not need to provide a large force to maintain the water flow.

[0011] Preferably, the outer periphery of the outlet end of the switching pipe is provided with a convex ring, and a sealing ring is provided between the convex rings to form a sealing structure between the switching pipe and the interface.

[0012] Preferably, the bottom of the interface is provided with a sealing gasket facing the water outlet of the switching pipe to improve the sealing effect when the water is turned off.

[0013] Preferably, the water passage hole is located on the periphery of the interface, which can increase the water outlet area and prevent the water output from decreasing.

[0014] Preferably, to avoid the difficulty of one-piece molding, the water inlet end of the handle is threaded with a water inlet connector, the water inlet channel and the telescopic port are set inside the water inlet connector, and one end of the water outlet seat is screwed into the water outlet end of the handle, and the other end is connected to the water outlet head of the spray gun.

[0015] Preferably, the water outlet head and the water outlet base are connected by a snap fastener, making them easy to disassemble, replace, or clean.

[0016] Preferably, the water outlet head has a through hole in the middle of the water outlet surface, and the water outlet nozzle of the water outlet head is designed to surround the through hole, thereby expanding the water outlet range and having a strong sense of design.

[0017] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0018] The spray gun provided by this utility model has a telescopic tube-type switching structure for its switching component. When water is flowing, the area of ​​the water inlet end of the switching shaft submerged in water is very small. Therefore, the water pressure on the switching shaft is very small when it moves telescopically, making the spray gun lighter and easier to use, and providing a better user experience. In addition, the spray gun switching structure provided by this utility model is simple and easy to manufacture and assemble.

[0019] The cross-section of the outlet end of the switching tube is larger than that of the inlet end. Therefore, when the water is flowing out, the water force at the outlet end of the switching tube is greater, which can further counteract the elastic force of the elastic element, so that the user does not need to provide a large force to maintain the water flow.

[0020] The water outlet head and water outlet base are connected by a screw fastener, making them easy to disassemble, replace, or clean.

[0021] The water outlet head is designed to resemble a hair dryer, which expands the water outlet range and has a strong sense of design. Attached Figure Description

Detailed Implementation

[0032] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0033] Please see Figures 1 to 7 A lightweight spray gun includes a spray gun body 1 and a switching assembly 2.

[0034] The spray gun body 1 includes a handle 11 and a water outlet 12. The handle 11 has a water inlet channel 111 and a mounting cavity 112, and a clearance opening 113 communicating with the handle 11 is provided on the periphery of the handle 11. A telescopic port 114 is provided between the water inlet end of the water inlet channel 111 and the water inlet end of the mounting cavity 112, and a water outlet seat 115 is provided at the water outlet end of the mounting cavity 112. The water outlet seat 115 has a coupling interface 1151 that is opposite to and coaxial with the telescopic port 114. The coupling interface 1151 has a water passage hole 1152 communicating with the water outlet 12.

[0035] In one embodiment, to avoid the difficulty of one-piece molding, a water inlet connector 116 is threaded onto the water inlet end of the handle 11. The water inlet channel 111 and the telescopic port 114 are disposed inside the water inlet connector 116. One end of the water outlet seat 115 is screwed into the water outlet end of the handle 11, and the other end is connected to the water outlet head 12 of the spray gun.

[0036] Based on the above embodiments, the water outlet head 12 and the water outlet base 115 are connected by a screw thread, making them easy to disassemble, replace, or clean. In addition, the water outlet head 12 has a through hole in the center of its water outlet surface, and the water outlet nozzle of the water outlet head 12 is designed to surround the through hole, thereby expanding the water outlet range and giving it a strong sense of design.

[0037] The switching component 2 includes a switching tube 21, an elastic element 22, and an operating element 23.

[0038] The inlet end of the switching pipe 21 is telescopically installed inside the telescopic port 114 and connected to the inlet channel 111. The outlet end of the switching pipe 21 is telescopically inserted into the connector 1151 and is offset from the water passage 1152. The periphery of the switching pipe 21 is sealed with both the telescopic port 114 and the connector 1151 to prevent water from leaking to the outer periphery of the switching pipe 21.

[0039] Preferably, the cross-section of the outlet end of the switching pipe 21 is larger than the cross-section of the inlet end. Therefore, in the water-outflow state, the water force on the outlet end of the switching pipe 21 is greater, which can further counteract the elastic force of the elastic element 22, thus allowing the user to maintain the water flow without exerting a large force. In one embodiment, a convex ring 211 is provided on the outer periphery of the outlet end of the switching pipe 21, and a sealing ring is provided between the convex rings 211, forming a sealing structure between the switching pipe 21 and the interface 1151.

[0040] The elastic element 22 is disposed between the switching tube 21 and the handle 11, and pushes the water outlet end of the switching tube 21 tightly against the end of the connector 1151 when the water is turned off, forming a sealed state. Preferably, the bottom of the connector 1151 is provided with a sealing gasket 1153 facing the water outlet end of the switching tube 21 to improve the sealing effect when the water is turned off.

[0041] In one embodiment, the elastic element 22 is a spring tube, which is compressed and sleeved on the outer periphery of the switching tube 21. One end abuts against the end of the telescopic port 114 facing the mounting cavity 112, and the other end abuts against the annular protrusion 212 on the outer periphery of the switching tube 21. The structure is simple and provides uniform restoring force.

[0042] The operating component 23 is movably mounted at the clearance opening 113 of the handle 11 and is linked to the switching tube 21. The switching tube 21 is disengaged from the interface 1151 by the switching action of the operating component 23, and the water outlet of the switching tube 21 is opened, allowing the switching tube 21 to connect to the water passage 1152, thus opening the spray gun. Preferably, the water passage 1152 is located on the periphery of the interface 1151, which increases the water outlet area and prevents a reduction in water flow.

[0043] In one embodiment, the switching tube 21 is provided with an annular linkage groove 213 on its outer periphery, and the operating member 23 is oscillatingly mounted on the handle 11 and is provided with a linkage block 231 extending to the outer periphery of the switching tube 21. The linkage block 231 is located in the annular linkage groove 213. When water needs to be discharged, the operating member 23 is pressed, and the operating member 23 rotates and drives the switching tube 21 to move axially.

[0044] Regarding the installation method of the spray gun, the water inlet connector 116 can be installed first, and then the switching component 2 and the water outlet seat 115 can be installed into the mounting cavity 112 in sequence. Alternatively, the water outlet seat 115 can be installed first, and then the switching component 2 and the water inlet connector 116 can be installed.

[0045] The spray gun provided by this utility model has a telescopic tube switching structure in its switching component 2. When water is flowing, the area of ​​the water inlet end of the switching shaft submerged in water is very small. Therefore, the water pressure on the switching shaft is very small when it moves telescopically, making the spray gun lighter and easier to use, and providing a better user experience. In addition, the spray gun switching structure provided by this utility model is simple and easy to manufacture and assemble.
