Description

Technical Field

[0001] This utility model relates to the technical field of bathroom accessories, and in particular to a switching structure for a spray gun shower head. Background Technology

[0002] A shower head is a common shower appliance in the bathroom. It usually includes a handle connected to a water pipe and a water outlet device installed at the end of the handle away from the water pipe. Water flows out through the water pipe, the handle, and the water outlet device in sequence.

[0003] Currently, showerheads with spray gun functions are becoming increasingly popular among consumers. By switching the showerhead to spray gun mode, the powerful water jets can be used to clean the walls and floors of the bathroom or kitchen without the need for an additional spray gun, saving costs and space.

[0004] However, existing shower heads with spray gun functions cannot automatically reset when switching. For example, when switching to spray gun water, they cannot automatically switch back to regular shower water. Because the spray gun water is powerful, it can easily impact objects and cause them to fall. Furthermore, most shower heads are hung on the shower head holder with the spray gun nozzle facing upwards, which can easily impact items such as light bulbs, posing a certain danger.

[0005] Therefore, the inventor specifically designed a switching structure for a spray gun shower head, which led to this invention. Utility Model Content

[0006] This utility model addresses the technical problem by providing a switching structure for a spray gun showerhead, overcoming at least one of its defects; the technical solution adopted is:

The water channel assembly 200 is provided with a shower head inlet 201 and a spray gun inlet 202. The switching device 300 includes a guide slider 320 and a central bolt 310 disposed at one end of the guide slider 320. The central bolt 310 is provided with a first sealing end 301 and a second sealing end 302. The switching device 300 also includes a first spring 330 for pressing the first sealing end 301 against the spray gun inlet 202. The guide slider 320 pulls the central bolt 310 to press the second sealing end 302 against the shower head inlet 201. The housing 100 is hollow and can adopt an existing structure to facilitate the installation of the water channel assembly 200 inside the housing 100.

[0040] Please see Figures 5-10The water channel assembly 200 includes an inlet pipe 210, a water channel plug 220, and a water distribution pipe 230. The inlet pipe 210 is provided with a first water channel 211. The water distribution pipe 230 is provided with a first inlet 231, a diversion chamber 232, a second water channel 233, and a third water channel 234. The first inlet 231, the second water channel 233, and the third water channel 234 are all connected to the diversion chamber 232. The water channel plug 220 is located between the inlet pipe 210 and the water distribution pipe 230, and one end extends into the diversion chamber 232. The water channel plug 220 is provided with a switching water channel 221. Specifically, the first inlet 231, the diversion chamber 232, and the second water channel 233 are connected to form a shower water channel, and the first inlet 231, the diversion chamber 232, the switching water channel 221, and the third water channel 234 are connected to form a spray gun water channel. The shower inlet 201 is located at the end of the second water channel 233 near the diversion chamber 232, and the spray gun inlet 202 is located at the end of the switching water channel 221 near the diversion chamber 232. When the shower water channel is connected, the first sealing end 301 abuts against the water channel plug 220 to block the spray gun water channel. When the spray gun water channel is connected, the second sealing end 302 abuts against the water distribution pipe 230 to block the shower water channel.

[0041] An installation position 213 is provided at one end of the water inlet pipe 210. Several support steps 214 for supporting the water channel plug 220 are provided on the inner side of the installation position 213. An avoidance groove is provided on the outer side of the water channel plug 220. A water passage is formed between the inner side of the installation position 213 and one end of the water distribution pipe 230. The water passage is connected to the first water inlet 231.

[0042] First buckles 235 are provided on both sides of the outer side of the water distribution pipe 230, and first slots 212 are provided on the water inlet pipe 210 to cooperate with the first buckles 235. The water distribution pipe 230 is installed on the water inlet pipe 210 through the cooperation of the first buckles 235 and the first slots 212. Specifically, two first buckles 235 are symmetrically arranged on the outer side wall of the water distribution pipe 230, and the first slots 212 are provided at the corresponding positions on the water inlet pipe 210. Specifically, a protrusion is provided on the water inlet pipe 210, and the first slots 212 are provided on the protrusion. Since the water inlet pipe 210 is made of plastic, the protrusion has a certain elasticity so that the first buckles 235 can be installed into the first slots 212 by applying external force.

[0043] Please see Figure 2The switching device 300 is switched via the driving device 400. The driving device 400 drives the center bolt 310 away from the spray gun inlet 202 so that the second sealing end 302 abuts against the shower head inlet 201. The driving device 400 includes a guide seat 410 and a push button 420 disposed on and slidably connected to the guide seat 410. The push button 420 abuts against the guide slider 320 below, and is used to drive the center bolt 310 away from the spray gun inlet 202. Specifically, the guide slider 320 is provided with a first inclined portion 321, and the push button 420 is provided with a second inclined portion 421 below which can abut against the first inclined portion 321. When the push button 420 moves downward, the first inclined portion 321 pushes the second inclined portion 421 to move the center bolt 310. The guide seat 410 is fixed to the outside of the water channel assembly 200 by riveting or screwing, specifically on the water distribution pipe 230. A sliding hole 411 is provided on the inner side of the guide seat 410. The cross-section of the sliding hole 411 perpendicular to its central axis is square or round. A sliding part 422 is provided below the push button 420 to fit into the sliding hole 411. Simultaneously, a foolproof groove is provided on the side wall of the sliding hole 411 to prevent fooling during the installation of the push button 420. Second latches 423 are provided on both sides below the sliding part 422 to prevent the push button 420 from detaching from the guide seat 410. The drive unit 400 also includes a second spring 420 for resetting. When spray gun water is needed, an external force is continuously applied to the pressing button 420, and the second spring 420 stores elastic potential energy. When spray gun water is not needed, the external force is removed, and the pressing button 420 is reset under the action of the second spring 420. At the same time, under the action of the first spring 330, the center bolt 310 can be reset, cutting off the spray gun water.

[0044] An clearance hole is provided on the outer casing 100 to communicate with the interior, so as to install the press button 420 on the guide seat 410. During installation, the guide seat 410 is first riveted or screwed onto the water pipe 230. After the water channel assembly 200 and the switching device 300 are assembled, they are placed inside the outer casing 100. After one end of the second spring 420 is pressed against the guide seat 410, the sliding part 422 is used to slide the sliding hole 411, and the second buckle 423 passes through the sliding hole 411 to realize the installation of the press button 420.

[0045] The guide slider 320 has a convex mounting groove, and the center bolt 310 has an annular groove that matches the mounting groove, so that one end of the center bolt 310 is embedded in the groove. When the guide slider 320 moves, it pulls the center bolt 310 to move. Specifically, one end of the center bolt 310 passes through the water distribution pipe 230 and connects to the guide slider 320. Then, the water channel plug 220 is placed in the water inlet pipe 210, and one end of the water distribution pipe 230 with the center bolt 310 is embedded in the water inlet pipe 210. Then, the installation is achieved by the first buckle 235 cooperating with the first groove 212, so that the water channel plug 220 is restricted between the water inlet pipe 210 and the water distribution pipe 230.

[0046] An annular step 311 is provided on the central throttle 310. A first spring 330 is disposed between the annular step 311 and the water distribution pipe 230. A first sealing ring 500 and a second sealing ring 600 are provided on the outer wall of the annular step 311 to form a first sealing end 301 and a second sealing end 302. The first sealing ring 500 is a Y-type sealing ring. Other sealing locations that need to be sealed are sealed with sealing rings as needed. The type of sealing ring can be selected according to actual requirements, or the positions of the various sealing rings can be referred to in the attached diagram.

[0047] The shower head of this utility model also has a water distribution body, a water outlet panel, and a spray gun head. The water outlet panel is used to dispense shower water, and the spray gun head is used to dispense spray gun water. The water distribution body has a first water passage for shower water and a second water passage for spray gun water. The second water passage 233 is connected to the first water passage, so that water can be dispensed from the water outlet panel. The third water passage 234 is connected to the second water passage, so that water can be dispensed from the spray gun head. The specific structure and connection method of the water distribution body, the water outlet panel, and the spray gun head can all adopt existing technology and will not be described in detail.

[0048] In summary, the shower head of this utility model defaults to spraying water. By setting a first spring, the first sealing end abuts against the spray gun inlet, preventing the problem caused by the spray gun water coming out directly when the shower head is turned on. At the same time, a movable central bolt is also set. After the central bolt moves, the second sealing end abuts against the shower head inlet, so that the shower head can also spray water, making it convenient to use.
