[0030] The toilet spray gun with a replaceable nozzle of this application can be used in occasions where the nozzle needs to be replaced, and of course it can also be used in other similar application scenarios. The following is a detailed description of a toilet spray gun with a replaceable nozzle.

[0031] See appendix Figure 1 — Figure 7 The diagram shows a preferred embodiment of a toilet spray gun with a replaceable nozzle according to this application. The toilet spray gun with a replaceable nozzle includes a spray gun bracket 1, a power source 2 mounted on the spray gun bracket 1, and a movable gun body 3 movably mounted on the spray gun bracket 1 and connected to the power source 2. A nozzle 4 is detachably mounted at the front end of the movable gun body 3, and a detachable connection structure 5 is provided between the nozzle 4 and the movable gun body 3.

[0032] In this invention, the power source 2 is an electric motor used to drive the mobile gun body 3 to extend and retract, which is prior art and therefore will not be described in detail here. The detachable connection structure 5 allows for a detachable connection between the gun head 4 and the mobile gun body 3, enabling the gun head 4 to be removed from the mobile gun body 3. This allows the user to periodically disinfect or replace the gun head 4, thereby reducing contaminants on the gun head 4 and minimizing the possibility of contaminants being transferred to the user's skin or mucous membranes during use. This reduces the risk of infection and other health risks for the user, thus protecting their health.

[0033] See appendix Figure 1 — Figure 5 As shown, in this utility model, the movable gun body 3 has a boss 31 on one end facing the gun head 4, and the gun head 4 has a groove 41 corresponding to the boss 31; the detachable connection structure 5 is provided on the boss 31 and the gun head 4.

[0034] The present invention, through the setting of the boss 31 and the groove 41, enables the movable gun body 3 and the gun head 4 to be connected in cooperation, providing installation conditions for the detachable connection structure 5.

[0035] See appendix Figure 2 — Figure 7 As shown, in this utility model, the boss 31 is provided with a first sealing groove 32, and a first sealing ring 33 is installed on the first sealing groove 32. The boss 31 is provided with a connecting pipe 34; the groove 41 is provided with a mating interface 42 corresponding to the connecting pipe 34.

[0036] This utility model provides installation conditions for the first sealing ring 33 by setting the first sealing groove 32, preventing leakage at the connection position of the boss 31 and the groove 41, and ensuring the sealing between the boss 31 and the groove 41; by setting the connecting pipe 34, in conjunction with the interface 42, it ensures that the rinsing liquid can be sprayed out from the nozzle 4.

[0037] See appendix Figure 2 — Figure 7 As shown, in this invention, the connecting pipe 34 is provided with a second sealing groove 341, and a second sealing ring 342 is installed on the second sealing groove 341. This invention provides the installation conditions for the second sealing ring 342 through the provision of the second sealing groove 341. Furthermore, through the second sealing ring 342, when the connecting pipe 34 is engaged with the connecting interface 42, the connecting pipe 34 is inserted into the connecting interface 42, causing the second sealing ring 342 to contact the inner wall of the connecting interface 42, thereby improving the sealing performance at the connection between the connecting pipe 34 and the connecting interface 42.

[0038] See appendix Figure 1 — Figure 7As shown, in this utility model, the detachable connection structure 5 includes a post 51 movably mounted on the top of the boss 31, a mating hole 52 on the gun head 4 corresponding to the post 51, a mounting hole 53 on the gun head 4 corresponding to the mating hole 52, and a disassembly component 54 installed in the mounting hole 53. The mating hole 52 and the mounting hole 53 are connected. It should be noted that the boss 31 has a countersunk hole 311 corresponding to the post 51. The post 51 has a T-shaped cross-section. A limiting ring 312 is provided at the opening of the countersunk hole, and a return spring 313 is installed at the bottom of the countersunk hole 311.

[0039] This invention, through the setting of the insertion post 51 and the mating hole 52, allows the insertion post 51 to be inserted into the mating hole 52 when the gun head 4 is connected to the movable gun body 3, thus mounting the gun head 4 onto the movable gun body 3 and connecting the gun head 4 to the movable gun body 3. The mounting hole 53 provides an installation position for the disassembly component 54. The disassembly component 54 is used to insert the insertion post 51 into the mating hole 52, connecting the gun head 4 and the movable gun body 3, and can also move the insertion post 51 to separate it from the mating hole 52, ensuring that the gun head 4 can be separated from the movable gun body 3 and disassembled. The return spring 313 provides power to the insertion post 51, allowing it to be inserted into the mating hole 52.

[0040] See appendix Figure 5 — Figure 7 As shown, in this invention, the mating hole 52 and the mounting hole 53 are concentrically arranged, and the diameter of the mating hole 52 is smaller than the diameter of the mounting hole 53. By limiting the concentric arrangement of the mating hole 52 and the mounting hole 53, this invention ensures that the insertion post 51 can be controlled by the disassembly component 54.

[0041] See appendix Figure 5 — Figure 7 As shown, in this utility model, the disassembly component 54 includes a movable column 541 adapted to the mounting hole 53, a disassembly column 542 installed at the bottom of the movable column 541, and a protrusion 543 installed at the top of the movable column 541; wherein, the diameter of the disassembly column 542 is equal to that of the limiting insert 512, and the disassembly column 542 is provided with a chamfer.

[0042] This invention utilizes the movable column 541, which moves within the mounting hole 53, thereby moving the disassembly column 542 and controlling the engagement and disengagement of the insertion column 51 and the mating hole 52. The disassembly column 542 presses down the limiting block 512, separating it from the mating hole 52. The protruding block 543 protrudes from the surface of the gun head 4, facilitating user pressure and causing the disassembly column 542 to descend, thus separating the insertion column 51 from the mating hole 52. It should be noted that the protrusion of the protruding block 543 from the gun head 4 is not less than the distance from the disassembly column 542 to the opening of the mating hole 52, ensuring easy user pressure to separate the insertion column 51 from the mating hole 52.

[0043] See appendix Figure 5 — Figure 7 As shown, in this utility model, the insert 51 includes a limiting base plate 511 and a limiting insert block 512 disposed on the limiting base plate 511. The limiting insert block 512 corresponds to the limiting ring 312. A spring 531 is installed in the mounting hole 53. The two ends of the spring 531 are in contact with the movable post 541 and the opening of the mounting hole 53, respectively.

[0044] This utility model uses spring 531 to support the movable column 541 while also allowing the movable column 541 to reset. Specifically, after the user presses the protrusion 543, the protrusion 543 can reset, preparing for the next press. It should be noted that the stroke of spring 531 is not less than the distance between the disassembly column 542 and the opening of the mating hole 52, thereby ensuring that after the user presses the protrusion 543, spring 531 can be compressed accordingly, causing the disassembly column 542 to move accordingly, and driving the insertion column 51 to separate from the mating hole 52.

[0045] See appendix Figure 5 — Figure 7 As shown, in this utility model, an installation groove 532 is provided at the opening of the installation hole 53, and a sealing ring 533 is installed in the installation groove 532. The protrusion 543 protrudes through the sealing ring 533 and protrudes from the surface of the gun head 4.

[0046] This utility model uses a capping ring 533 to limit the movable column 541, prevent the movable column 541 from separating from the mounting hole 53, and avoid the protruding block 543, allowing the user to press the protruding block 543. It should be noted that the diameter of the protruding block 543 is smaller than the diameter of the movable column 541.

[0047] See appendix Figure 1 — Figure 7 As shown, the usage process of this utility model is as follows:

[0048] When it is necessary to disassemble the nozzle of the toilet spray gun, the user first controls the power source 2 via an external remote control or button, causing the movable gun body 3 and nozzle 4 to move outward to their normal operating position. Then, the user can press the protruding block 543. As the user presses the protruding block 543, it moves inward along the mounting hole 53, causing the movable column 541 to move within the mounting hole 53, which in turn moves the disassembly column 542. This causes the insertion post 51, which is in contact with the disassembly column 542, to move downward until the user can no longer continue. Continue pressing until the bottom of the insertion post 51 contacts the bottom of the countersunk hole 311, and the insertion post 51 separates from the mating hole 52. It should be noted that at this time, the surface of the disassembly post 542 is flush with the surface of the limiting ring 312, and it can be pulled out smoothly. When the disassembly post 542 is partially inserted into the countersunk hole 311, when the gun head 4 is pulled out, the chamfered surface on the disassembly post 542 will contact the countersunk hole 311, pushing the protrusion 543 to generate an upward force. The user can release the protrusion 543 and then pull out the gun head 4. The operation is simple and convenient.

[0049] When it is necessary to install the gun head 4, simply align the groove 41 on the gun head 4 with the boss 31 on the movable gun body 3 and insert it. Since the groove 41 has a chamfer at the opening, it can guide the insertion post 51. Press the insertion post 51, and when the gun head 4 moves to the designated position, the insertion post 51 is inserted into the mating hole 52 through the return spring 313, thus completing the installation of the gun head 4.

[0050] See appendix Figure 8 As shown, the movable gun body 3 and the gun head 4 in this application can be replaced, so that the number and shape of the water outlet holes on the gun head 4 can be changed by replacing different gun heads 4. It is only necessary to ensure that the boss 31 on the movable gun body 3 and the groove 41 on the gun head 4 can cooperate, and the boss 31 and the groove 41 can be connected by a detachable connection structure 5.

[0051] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
