[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1 aims to address the problem of time-consuming and laborious car washing processes, such as applying cleaning solution, wiping with a cloth, and rinsing with water when the car body is dirty. Please refer to [link to example 1]. Figures 1-6 A water gun for irrigation and cleaning with a large nozzle 111 includes a gun body 110 and a nozzle 111, with a water inlet connector 112 installed at the bottom of the gun body 110.

[0029] See Figures 1-3The gun body 110 is provided with a switch valve core 113 for controlling the water flow. The end of the gun body 110 is provided with a connector 114 for connecting the nozzle 111 assembly. A foam box 115 is provided on the side of the connector 114. A container 116 for holding cleaning fluid is provided at the bottom of the foam box 115. A head shell 117 is provided on the side of the foam box 115 assembly. A base 118 for fixing the nozzle 111 is provided on the side of the head shell 117. The nozzle 111 is located on the side of the base 118.

[0030] See Figure 3 and Figure 4 A positioning shaft 120 is installed at the end of the connector 114. A buckle 121 is installed on the positioning shaft 120. A bushing 122 is fitted over the positioning shaft 120. The bushing 122 has a groove 123 corresponding to the buckle 121. The buckle 121 engages with the groove 123. The design of the positioning shaft 120 and the buckle 121 ensures the stability of the nozzle 111 during the spraying process and prevents it from loosening.

[0031] A water passage cavity 124 is provided inside the gun body 110, and a control groove 125 is provided inside the gun body 110. The control groove 125 is connected to the water passage cavity 124. The switch valve core 113 is located inside the control groove 125. A water sealing pad 126 is provided on the switch valve core 113. The water sealing pad 126 is a rubber pad. A rotating shaft 127 is installed on the side of the switch valve core 113. The rotating shaft 127 is inserted into the gun body 110 and is semi-circular.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 6 A switch wrench 128 is installed on the outside of the gun body 110. A through groove 129 is opened in the switch wrench 128. The switch valve core 113 is inserted into the gun body 110 through the through groove 129 on one side of the switch wrench 128. A wrench cover 130 is installed in the through groove 129 on the other side of the switch wrench 128. A mounting block 131 is installed on the wrench cover 130. A mounting groove 132 corresponding to the mounting block 131 is opened in the through groove 129. The mounting groove 132 communicates with the through groove 129. The mounting block 131 engages with the mounting groove 132.

[0033] See Figure 3 and Figure 4 A positioning pin 148 is installed on the protective cover 144. Several positioning slots 149 for switching different sections are opened on the outside of the nozzle 111, and the positioning slots 149 correspond to the positioning pins 148. A water inlet 150 is installed on the end of the nozzle 111 away from the water outlet 141. A flow regulator 151 for adjusting the water flow is provided outside the water inlet 150. The container 116 is installed at the bottom of the flow regulator 151, and the foam box 115 is installed on the flow regulator 151.

[0034] When the rotary flow switch is in the cleaning mode, the water first enters the container 116 and then the nozzle, and the cleaning solution is sprayed out in a foamy form. To increase the flow rate, the nozzle 111 is larger than usual, and the outlet is also larger. The high flow rate is very effective for cleaning vehicles or other items. When the flow switch is switched to the spray mode, the water does not pass through the container 116 and goes directly to the nozzle, which can be used as a regular water gun to spray green plants.

[0035] The gun body 110 assembly and the nozzle 111 assembly are independent, but can be connected in series via connector 114. If it is only for water replenishment, depending on the object and location being irrigated, the nozzle 111 can be replaced by rotating the gun body 110 90° clockwise, the nozzle 111 assembly can be removed, a new nozzle 111 can be installed, and the switch can be turned on to spray. To ensure good interchangeability, the disassembly method of all nozzles 111 is the same, making operation very convenient.

[0036] The switch lever is ergonomically designed, featuring a front or rear trigger mechanism supported by a latch 121. By moving the switch lever 128 up and down with the thumb, the spraying can be activated or deactivated. Furthermore, as the switch is pushed, the flow rate is automatically and steplessly adjusted; the higher the lever is pushed, the greater the flow rate, resulting in an automatic flow control process. This saves effort and time.

[0037] The water gun for irrigation and cleaning in this embodiment has significant advantages in improving work efficiency, saving time and labor, meeting the needs of modern maintenance and cleaning, and providing a more convenient and efficient operating experience.

[0038] In this embodiment: by mixing the cleaning solution with water to form a foam spray, the cleaning effect is improved and the cleaning time is reduced. By controlling the up and down movement of the control switch 128, stepless flow adjustment is achieved, which is simple to operate and reduces fatigue from pressing the trigger for a long time. The foam spraying of the cleaning solution can be achieved by rotating the flow switch, reducing the steps of applying cleaning solution and wiping. For watering large areas or scattered plants, the task can be completed quickly by changing the nozzle 111, reducing the labor intensity of manually holding the water gun. The gun body 110 component and the nozzle 111 component are designed independently and connected in series by the connector 114, which is convenient for maintenance and replacement. The design of the positioning shaft 120 and the buckle 121 ensures the stability of the nozzle 111 component during the spraying process and prevents loosening.

[0039] Example 2 aims to address the issue of uneven water flow that may result from a single water outlet. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-6The nozzle 111 is a multi-segment nozzle. A water channel 140 is formed inside the nozzle 111. A water outlet 141 is installed at the end of the nozzle 111, and several water-dividing plates 142 are provided inside the water outlet 141. A first sealing ring 143, made of rubber, is also provided inside the water outlet 141. The use of wear-resistant materials such as rubber rings increases the durability of the nozzle 111 and extends the service life of the equipment. A protective cover 144 is fitted over the nozzle 111. A threaded hole 145 is formed on the protective cover 144, and a screw 146 is threaded into the threaded hole 145. Several water outlet holes 147, corresponding to the water-dividing plates 142, are formed on the protective cover 144 and communicate with the water channel 140.

[0040] See Figure 4 The protective cover 144 not only provides protection but also allows for quick disassembly and installation via rotating screw 146, facilitating cleaning and maintenance of the internal structure of the nozzle 111. The multi-segment nozzle design allows for switching between different spray modes, such as mist or water jet, to meet the needs of various scenarios. A first sealing ring 143 within the water outlet 141 enhances the seal between the nozzle 111 and the water outlet 141, preventing water leakage at the connection and ensuring sufficient water pressure during cleaning or irrigation.

[0041] The protective cover 144 is secured by screws 146, ensuring a tight seal between the protective cover 144 and the nozzle 111 and preventing water leakage from the connection. It also prevents external contaminants from entering the nozzle 111, maintaining the cleanliness and stable performance of the equipment.

[0042] In this embodiment: by setting a multi-segment nozzle, the internal structure of the nozzle 111 can be better fixed, preventing the internal components of the nozzle 111 from loosening or shifting during use. The protective cover 144 is fixed to the outside of the nozzle 111 through threaded holes 145 and screws 146, which increases the overall stability of the nozzle 111 and prevents the nozzle 111 from deforming or being damaged under the action of high-pressure water flow. The design of the water channel 140 and the water divider 142 ensures that the water flow is evenly distributed inside the nozzle 111, avoiding the water flow from concentrating in a certain area and improving the coverage and uniformity of the spray. The water outlet 147 on the protective cover 144 corresponds to the water divider 142, ensuring that the water flow is evenly sprayed from multiple water outlets 147, solving the problem of uneven water flow that may be caused by a single water outlet.

[0043] Example 3 aims to address the potential leakage of cleaning fluid or water at joints. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-6 .

[0044] The container 116 is a transparent plastic tube with graduation lines 152 and an external threaded ring 153. The container 116 is threadedly connected to the flow regulator 151 via the external threaded ring 153. By making the container 116 a transparent plastic tube, the user can clearly see the remaining amount of cleaning fluid inside, avoiding the hassle of frequent checks and additions. The graduation lines 152 on the outside of the container 116 allow for accurate measurement of the cleaning fluid usage, ensuring the correct amount is obtained each time, thus improving operational convenience. The threaded connection between the container 116 and the flow regulator 151 allows for easy disassembly and installation of the container 116, facilitating cleaning and maintenance. Simultaneously, the external threaded ring secures the container, ensuring its stability under high-pressure water flow and preventing it from falling off or shifting.

[0045] See Figure 3 and Figure 6 A second sealing ring 154 is provided inside the water inlet connector 112, and a third sealing ring 155 is provided outside the container 116. Both the second sealing ring 154 and the third sealing ring 155 are rubber rings. The use of rubber rings improves the sealing performance of the connection and prevents water leakage from the connector. The container is threaded to the flow regulator via an external threaded ring, ensuring a tight connection and further improving the sealing effect to prevent cleaning fluid or water leakage at the connection.

[0046] In this embodiment: the second sealing ring 154 provided inside the water inlet connector 112 and the third sealing ring 155 provided outside the container 116 are both designed with rubber rings, which improves the sealing performance of the connection and prevents water from leaking from the connector. The container 116 is threaded to the flow regulator 151 through the external threaded ring 153, which ensures the tightness of the connection and further improves the sealing effect, preventing the cleaning fluid or water from leaking from the connection.
