Technical Field
[0001] This utility model relates to the technical field of kitchen and bathroom accessories, and in particular to a push-to-switch spray gun. Background Technology
[0002] Spray guns are very common in bathroom products and are mostly used for cleaning. They can provide powerful cleaning water for cleaning. Traditional spray guns have a relatively simple structure and mostly control the opening and closing of the cleaning water by pressing. That is, there is often a water outlet switch on the handle. When using it, you hold the handle and press the switch at the same time.
[0003] However, using a push-button opening and closing mechanism may have the following problems: First, using a spring for reset makes spring installation relatively inconvenient and assembly relatively complex; second, when the water pressure is too high, a large force is required to press it, and there may even be problems such as not being able to press it at all.
[0004] Therefore, the inventor specifically designed a push-to-switch spray gun, which led to this invention. Utility Model Content

[0033] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.
[0034] Please see Figures 1 to 8This utility model provides a push-to-switch spray gun, comprising a body 10 and an inlet pipe 20 disposed within and slidably connected to the body 10. The body 10 is hollow inside, with an inlet end 11 at one end and an outlet channel 12 at the other end away from the inlet end 11. The body 10 also has a first outlet 13 for connecting the interior to the outlet channel 12. The inlet pipe 20 has an inlet channel 21 inside, connecting to the inlet end 11, and a second outlet 22 on its side wall, connecting to the inlet channel 21. Pushing the inlet pipe 20 connects the first outlet 13 to the second outlet 22, or displaces the first outlet 13 from the second outlet 22. That is, when the first outlet 13 is connected to the second outlet 22, the spray gun opens to dispense water; when the first outlet 13 is displaced from the second outlet 22, the spray gun closes to stop dispensing water.
[0035] Please see Figure 3 At least one second water outlet 22 is provided; this utility model provides two, and both second water outlets 22 are connected to the water outlet channel 12. The water inlet pipe 20 is hollow inside to form a water inlet channel 21. This hollow design facilitates easier movement of the water inlet pipe 20. Specifically, when the spray gun is in the closed state, i.e., the first water outlet 13 and the second water outlet 22 are not connected, the body 10 is filled with water. The water pressure applied to both ends of the water inlet pipe 20 is in a relatively balanced or nearly balanced state. When the spray gun needs to be opened, only a small external force needs to be applied (this external force only needs to overcome the friction generated by the water inlet pipe 20 and the push assembly 30 during movement). Push the inlet pipe 20 until the first outlet 13 and the second outlet 22 at least partially overlap; and due to the existence of friction, the inlet pipe 20 can remain stationary when the external force is removed. When it is necessary to close the spray gun, the inlet pipe 20 is in the water, and the force applied to both ends of the inlet pipe 20 by the water pressure is the same or tends to be the same. Therefore, it can be closed with only a small external force. The push-pull structure ensures that the pressure applied to the inlet pipe 20 is the same or tends to be the same regardless of the state, so as to achieve easy opening and closing.
[0036] Please see Figure 2-4 The push-to-switch spray gun of this utility model also includes a push-to-switch assembly 30 for pushing the water inlet pipe 20 to slide within the body 10. That is, the push-to-switch assembly 30 can drive the water inlet pipe 20 to move, thereby realizing whether the first water outlet 13 and the second water outlet 22 are connected or not, and thus controlling the opening and closing of the spray gun. The push-to-switch assembly 30 includes a push-to-switch piece 31 disposed on the outer wall of the body 10 and a push-to-switch key 32 disposed on the push-to-switch piece 31. The push-to-switch key 32 drives the push-to-switch piece 31 to move on the outer wall of the body 10.
[0037] Please see Figure 5The push-pull plate 31 has a first through hole 311 for mounting the push-pull key 32. Below the push-pull key 32, two parallel first steps 321 are provided. A latching part 322 is provided on the outer side of the two first steps 321, through which the push-pull key 32 is mounted onto the push-pull plate 31. There is a gap between the two first steps 321, and the lower outer side of the latching part 322 has an inclined surface for easy installation. This inclined surface allows the latching part 322 to pass more easily through the first through hole 311.
[0038] Please see Figure 3 , 4 The outer wall of the water inlet pipe 20 is provided with a push-pull part 23 facing away from its central axis. The push-pull part 23 passes through the body 10 and is embedded in the push-pull plate 31. The body 10 is provided with a clearance channel 13 for the push-pull part 23 to pass through and avoid the movement of the push-pull part 23. The push-pull plate 31 is also provided with a second through hole 312 for the push-pull part 23 to be embedded. The push-pull part 23 and the water inlet pipe 20 can be an integral structure or a separate structure.
[0039] Please see Figure 4 The main body 10 adopts a split structure to facilitate the installation of the water inlet pipe 20. It includes a first slide 40 and a second slide 50. The water inlet end 11 is located at one end of the first slide 40, and the water outlet channel 12 and the first water outlet 13 are located on the second slide 50. The first slide 40 is provided with a first sliding groove 41 near the end of the second slide 50, and the second slide 50 is provided with a second sliding groove 51 near the end of the first slide 40. One end of the first slide 40 is embedded in the second slide 50, and the first sliding groove 41 and the second sliding groove 51 form a clearance channel 13. During installation, the pushing part 23 is aligned with the second slide, then the water inlet pipe 20 is placed into the second slide, then the second sliding groove 51 is aligned with the first sliding groove 41, one end of the first slide is embedded into the second slide, and finally one end of the first slide is fixed to the second slide.
[0040] Please see Figure 4 Two first grooves 24 are provided on the outer wall of the water inlet pipe 20. A first sealing ring 80 is embedded in the first groove 24. The second water outlet 22 is located between the two first grooves 24. The two first sealing rings 80 can be used to open and close the spray gun. Specifically, the first groove 24 is formed by two annular steps. Then, the first sealing ring 80 is placed between the two annular steps. After the water inlet pipe 20 is installed, the first sealing ring 80 is pressed between the outer wall of the water inlet pipe 20 and the inner wall of the body 10.
[0041] Please see Figure 1 , 2The spray gun also includes a housing 60 (equivalent to a handle) and a water outlet device 70. The main body 10 is embedded in the housing 60, and the water outlet device 70 is disposed on the housing 60. The water outlet device 70 of this invention adopts a simplified design and can directly utilize existing devices, such as an aerator. The housing 60 is also provided with an elongated hole 61 communicating with the interior. The elongated hole 61 is used to install the push button 32 and to prevent the push button 32 from sliding. The push plate 31 is disposed on the inner side wall of the housing 60; after the first step 321 of the push button 32 passes through the housing 60 and the push plate 31, the latching part 322 hooks the push plate 31. After the main body 10 and the water inlet pipe 20 are installed, the push plate 31 is placed on the outer wall of the main body 10, and the push part 23 is set in accordance with the second through hole 312. Then, the whole is put into the outer shell 60. After it is placed in place, the push key 32 is passed through the elongated hole 61 and snapped into the push plate 31. The overall assembly is relatively simple.
[0042] To better confine the main body 10 within the outer shell 60, two limiting steps are provided on the outer side of the main body 10, and corresponding limiting grooves are provided inside the outer shell 60. Specifically, two locking steps are provided inside the outer shell 60 to form limiting grooves. During installation, the limiting steps are simply embedded into the two locking steps. Meanwhile, other sealing structures and methods in this utility model are not existing technologies and will not be described in detail.
[0043] In summary, the switchable spray gun of this utility model has a sliding water inlet pipe. The water flow can be turned on and off by moving the water inlet pipe. Pushing the water inlet pipe will open the spray gun and allow water to flow when the first water outlet is connected to the second water outlet; when the first water outlet and the second water outlet are misaligned and not connected, the spray gun will close and stop water flow. The overall structure is simple, easy to assemble, and relatively labor-saving.
