Detailed Implementation
[0017] In this technical solution: To make the objectives, technical solutions, and advantages of this utility model clearer, 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 merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] Reference Figure 1 As shown, this utility model proposes a multifunctional T-shaped spray gun, including a T-shaped body, an inner water channel, a seven-ring groove center bolt, a massage ball, and a face cover; The inner water channel is installed inside the T-shaped body in a detachable manner, that is, the bottom of the inner water channel is provided with at least one mounting hole, and screws are passed through the mounting hole to fix it to the T-shaped body. The cover is detachably installed at the end of the inner water channel via a snap-fit structure, and cooperates with the T-shaped body to form a closed space for lateral water discharge from the T-shaped body; The massage ball is detachably installed between the face cover and the inner water channel, and the massage ball can be movably extended out of the face cover surface; The seven-ring groove center bolt is slidably installed in the inner water channel along the axial direction of the inner water channel, and is used to synchronously control the lateral water outlet of the face cover and the water outlet of the top of the T-shaped body through the sliding action. The internal waterway includes a water inlet channel, an L-shaped connector, and a knob; The end of the L-shaped connector slides into the second groove provided in the inner waterway and is connected to the end of the seven-ring groove center bolt through the second groove. The knob passes through the first groove provided on the side of the T-shaped main body and is connected to the L-shaped connector. By moving the knob, the L-shaped connector is driven to slide synchronously along the first and second grooves. The first slide groove and the second slide groove are completely identical in position, length and sliding direction; The top of the inner waterway is provided with a water inlet channel that is connected to a water outlet for top water discharge.
[0019] The outer surface of the seven-ring groove center bolt is provided with at least three Y-shaped sealing rings along the axial direction. The Y-shaped sealing rings are interference-fitted with the inner wall of the inner water channel to seal the gap between the seven-ring groove center bolt and the inner water channel. The outer surface of the seven-ring groove center bolt is provided with seven annular grooves along the axial direction, which are numbered 1-7 from left to right. The axial length of annular grooves 1, 2, and 3 is the same. The annular grooves 1 and 3 are equipped with Y-shaped sealing rings, and the surfaces with the largest diameters of the two Y-shaped sealing rings are opposite each other; The No. 5 annular groove is equipped with a Y-type sealing ring, which is opposite to the surface of the maximum diameter of the Y-type sealing ring of No. 1; The No. 7 annular groove engages with the connector. The water injection channel is sealed and installed on the top of the inner water channel by a first sealing ring. The first sealing ring is an O-ring and is fitted between the outer wall of the water injection channel and the inner wall of the mounting hole of the inner water channel. The contact surface between the face cover and the T-shaped body is provided with a second sealing ring, which is an annular rubber ring used to seal the gap between the face cover and the T-shaped body to prevent liquid leakage when water is discharged from the side. The bottom of the inner water channel is provided with a sealing gasket, which is an elastic rubber gasket that fits between the bottom of the inner water channel and the bottom surface of the mounting groove of the T-shaped body; the bottom of the inner water channel is also provided with at least one mounting hole, through which screws are passed to fix it to the T-shaped body. The inner waterway also includes a ball bearing and a spring; the side wall of the inner waterway is provided with a groove, and the ball bearing is elastically installed in the groove by the spring, and the end of the ball bearing contacts the side wall of the L-shaped connector. When the knob is turned, the connector has a touch sensation, which can determine whether the gear is engaged. The face cover is provided with a welded component, and the massage ball is sandwiched between the welded component and the face cover. Working principle: The T-type spray gun drives the L-shaped connector and the seven-ring groove center plug through a toggle switch. Combined with the sealing logic of the Y-shaped sealing ring on the surface of the seven-ring groove center plug, it achieves precise switching between three modes: "side water outlet from the cover → closed → top side water outlet from the single injection port". The specific actions are as follows: First setting (side water outlet from the faceplate) (see reference) Figure 2 ): Move the dial to the right end of the first slide (initial position). The L-shaped connector slides synchronously to the right along the first slide (side of the T-shaped main body) and the second slide (side of the inner waterway), pushing the center bolt of the seven-ring groove to the right to its limit position (its end abuts against the inner wall of the T-shaped main body). At this time: The Y-shaped sealing rings (with their maximum diameters relative to each other) in the No. 1 and No. 3 annular grooves of the seven-ring groove center bolt are interference-fitted with the inner wall of the inner waterway to seal the gap between the left side of the seven-ring groove center bolt and the inner waterway. The Y-shaped sealing ring (with the largest diameter opposite to the No. 1 sealing ring) in the No. 5 annular groove fits with the inner wall of the inner waterway to seal the gap between the right side of the center bolt of the seven-ring groove and the inner waterway. The end of the central plug of the seven-ring groove does not block the water inlet channel of the T-shaped body, and the closed space formed by the cover and the T-shaped body is not blocked. Water flows directly from the inner water channel into the cover area, so that the cover can directly discharge water. Second gear (off state) (see reference) Figure 3 ): Move the toggle switch to the middle of the first slide groove. The L-shaped connector will move the center bolt of the seven-ring groove to the right to the middle position. At this time: The Y-shaped sealing rings in the 1st, 3rd, and 5th annular grooves of the seven-ring groove center bolt move synchronously, completely covering the water inlet channel of the inner water channel and the side water outlet channel of the cover. One of the water inlets (top side outlet channel) of the inner waterway is temporarily blocked by the No. 4 annular groove (without a sealing ring) of the center bolt of the seven-ring groove; All water outlet paths are sealed, and the spray gun is in the closed position to prevent water leakage; Third level (water flows out from the top side of the outlet) (see reference) Figure 4 ): Move the knob to the left end of the first slide groove. The L-shaped connector moves the center bolt of the seven-ring groove to its limit position (its seventh annular groove is engaged and fixed with the L-shaped connector). At this time: The Y-shaped sealing rings in the No. 1 and No. 3 annular grooves of the seven-ring groove center bolt cover the side water outlet channel, blocking the side water flow; The No. 4 annular trough and the inner water channel are connected to the water outlet on the top of the T-shaped main body. Water flows through the water channel and is sprayed out from the water outlet on the top side, which is suitable for local high-pressure cleaning scenarios. The auxiliary positioning of the ball and spring: During the operation of the dial, the positioning groove on the side wall of the L-shaped connector contacts the ball (which is pushed out by the spring elasticity) in the groove of the inner water channel. When the dial reaches the preset position, the ball is locked into the positioning groove under the spring force, producing a "click" tactile sensation. The user can accurately judge the completion of the gear switching through touch, avoiding misoperation. In addition to the above, this solution also has another method, in which the welded part can also be provided with a circular hole, so that the water flow of the inner water channel can act on the massage ball through the hole and drive its movement. That is, in the first gear, the flow flows directly from the inner water channel into the face cover area, and after acting on the massage ball through the hole of the welded part (driving its movement), it is sprayed out from the side of the face cover, realizing the simultaneous output of cleaning and massage functions.
