[0059] Axial P DETAILED DESCRIPTION

[0060] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0061] like Figure 1-Figure 4 As shown, this embodiment provides a nozzle assembly 10 , which includes: a nozzle body 11 , an adjustment component, and a magnetic adjustment assembly 13 .

[0062] A main flow channel 111 is provided in the nozzle body 11. An inlet 112 and an outlet 113 connected to the main flow channel 111 are respectively opened in the nozzle body 11 along the axial direction P of the main flow channel 111. A cover body 12 is provided on the outer side of the inlet 112. A side flow channel 114 connected to the main flow channel 111 is formed between the cover body 12 and the outer edge of the inlet 112.

[0063] The regulating component is disposed near the inlet 112 , and is used to change the flow rate of the gas entering the main channel 111 from the side channel 114 .

[0064] The magnetic adjustment component 13 includes a coil 131 and a magnet 132, one of which is disposed on the cover 12, and the other is disposed on the nozzle body 11 and connected to the adjustment component, and the coil 131 and the magnet 132 cooperate to drive the adjustment component to move.

[0065] In this way, by setting the overall structure of the nozzle assembly 10, the gas flow rate entering the main channel 111 from the side channel 114 can be adjusted, so that the gas flow rate can be changed during summer use, thereby avoiding the situation where the water outlet temperature of the gas water heater is too high. Specifically, through the cooperation of the coil 131 and the magnet 132, the adjustment component can be driven to move, thereby changing the gas flow rate entering the main channel 111 from the side channel 114.

[0066] In this embodiment, the magnet 132 is disposed on the cover 12, and the coil 131 is disposed on the nozzle body 11 and connected to the adjustment component. When the polarity generated by the end of the coil 131 close to the magnet 132 is opposite to the polarity of the end of the magnet 132 close to the coil 131, the coil 131 moves in a direction close to the magnet 132 to push the adjustment component to move in a direction close to the cover 12 to reduce the gas flow entering the side flow channel 114; when the polarity generated by the end of the coil 131 close to the magnet 132 is the same as the polarity of the end of the magnet 132 close to the coil 131, the coil 131 moves in a direction away from the magnet 132 to drive the adjustment component to move in a direction away from the cover 12 to increase the gas flow entering the side flow channel 114.

[0067] However, the present invention is not limited thereto. In other embodiments, the coil 131 may be disposed on the cover 12, and the magnet 132 may be disposed on the nozzle body 11 and connected to the adjusting component. When the polarity generated by the end of the coil 131 close to the magnet 132 is opposite to the polarity of the end of the magnet 132 close to the coil 131, the magnet 132 moves in a direction close to the coil 131 to push the adjusting component to move in a direction close to the cover 12; when the polarity generated by the end of the coil 131 close to the magnet 132 is the same as the polarity of the end of the magnet 132 close to the coil 131, the magnet 132 moves in a direction away from the coil 131 to drive the adjusting component to move in a direction away from the cover 12.

[0068] In this embodiment, the nozzle body 11 is provided with a mounting groove 115, which is arranged around the outer periphery of the inlet 112 and arranged along the axial direction P; the coil 131 and the adjustment component are both slidably arranged in the mounting groove 115. In this way, by sliding the coil 131 and the adjustment component in the mounting groove 115, the overall structure can be made more compact. Furthermore, the magnet 132 is annular and is arranged corresponding to the coil 131 arranged in the mounting groove 115.

[0069] Specifically, the regulating component is a cylindrical structure 15, and the cylindrical structure 15 is coaxially arranged with the main flow channel 111. When the polarity generated by the end of the coil 131 close to the magnet 132 is opposite to the polarity of the end of the magnet 132 close to the coil 131, the coil 131 moves in the direction close to the magnet 132 to push the cylindrical structure 15 to move in the direction close to the cover body 12, that is, push the cylindrical structure 15 from the initial position to the working position of reducing the gas flow entering the side flow channel 114; when the polarity generated by the end of the coil 131 close to the magnet 132 is the same as the polarity of the end of the magnet 132 close to the coil 131, the coil 131 moves in the direction away from the magnet 132 to drive the cylindrical structure 15 to move in the direction away from the cover body 12, that is, drive the cylindrical structure 15 to return from the working position to the initial position.

[0070] In this embodiment, the nozzle assembly 10 includes a plurality of support arms 18 connecting the cover body 12 and the nozzle body 11. The plurality of support arms 18 are arranged at intervals around the outer periphery of the inlet 112 and extend along the axial direction P of the nozzle body 11. The cylindrical structure 15 is sleeved on the outer side of the support arms 18. In this way, by providing the support arms 18, on the one hand, the connection between the cover body 12 and the nozzle body 11 is achieved, and on the other hand, a support function is provided for the cylindrical structure 15. Preferably, the number of support arms 18 is greater than or equal to three, but the total area is less than or equal to 50% of the cross-sectional area of ​​the side flow channel 114, so as to reduce the impact on the cross-sectional area of ​​the side flow channel 114 while providing effective connection and support. Preferably, the support arms 18 are arranged at equal intervals around the outer periphery of the inlet 112.

[0071] Preferably, the orthographic projection of the inlet 112 along the axial direction P is located within the outer edge of the cover body 12. In this way, by setting the orthographic projection of the inlet 112 along the axial direction P to be located within the outer edge of the cover body 12, the adjustment component can more easily adjust the side flow channel 114 formed between the cover body 12 and the outer edge of the inlet 112. The axial P distance D between the cover body 12 and the cylindrical structure 15 is 1.5mm to 2mm. By setting the value range of the distance D, the adjustment of the side flow channel 114 can be better achieved. Furthermore, one end of the cylindrical structure 15 is located in the mounting groove 115 and connected to the coil 131, and the other end at least partially protrudes from the mounting groove 115 to facilitate taking and adjustment.

[0072] In this embodiment, the nozzle assembly 10 further includes: an ambient temperature sensor and a controller. The ambient temperature sensor is used to detect the ambient temperature. The ambient temperature sensor and the coil 131 are electrically connected to the controller respectively. In this way, by setting the ambient temperature sensor to detect the ambient temperature; by setting the controller to control the coil 131 and receive the instantaneous ambient temperature detected by the ambient temperature sensor, the beneficial technical effect of adjusting the outlet water temperature of the gas water heater according to the instantaneous ambient temperature is achieved. Specifically, during the working process, the instantaneous ambient temperature is detected by the ambient temperature sensor and sent to the controller. The controller compares the instantaneous ambient temperature with the preset temperature, and controls the polarity generated by one end of the coil 131 close to the magnet 132 according to the comparison result, that is, if the instantaneous ambient temperature is greater than or equal to the preset temperature, the polarity generated by one end of the coil 131 close to the magnet 132 is opposite to the polarity of one end of the magnet 132 close to the coil 131; if the instantaneous ambient temperature is less than the preset temperature, the polarity generated by one end of the coil 131 close to the magnet 132 is the same as the polarity of one end of the magnet 132 close to the coil 131. For example, during use in the summer, in order to improve the user's comfort, it is necessary to reduce the gas flow rate and prevent the outlet water temperature of the gas water heater from being too high. The preset temperature can be set at 28 degrees. When the immediate ambient temperature is greater than or equal to the preset temperature, the controller controls the polarity generated by the end of the control coil 131 close to the magnet 132 to be opposite to the polarity of the end of the magnet 132 close to the coil 131, so as to reduce the gas flow rate entering the main channel 111 from the side flow channel 114, thereby achieving the beneficial technical effect of adjusting the outlet water temperature according to the immediate ambient temperature.

[0073] The working principle of the nozzle assembly 10 of this embodiment is as follows:

[0074] When the polarity generated by the end of the coil 131 close to the magnet 132 is opposite to the polarity of the end of the magnet 132 close to the coil 131, an attractive force is generated between the magnet 132 and the coil 131, and the coil 131 moves toward the magnet 132. Figure 1The movement in the direction of the middle arrow F reduces the axial distance D between the cover 12 and the cylindrical structure 15, that is, reduces the flow area of ​​the side flow channel 114 of the nozzle body 11, thereby reducing the gas flow rate and lowering the outlet water temperature of the gas water heater. This state is suitable for summer when the ambient temperature is high to ensure that the water temperature is cool enough for bathing in summer.

[0075] When the polarity of the end of the coil 131 close to the magnet 132 is the same as the polarity of the end of the magnet 132 close to the coil 131, a repulsive force is generated between the magnet 132 and the coil 131, and the coil 131 moves away from the magnet 132. Figure 1 The reverse movement of the middle arrow F increases the axial distance D between the cover body 12 and the cylindrical structure 15, that is, increases the flow area of ​​the side flow channel 114 of the nozzle body 11, thereby increasing the gas flow rate and improving the outlet water temperature of the gas water heater. This state is suitable for winter when the ambient temperature is low to ensure that the water temperature is hot enough for bathing in winter.

[0076] Figure 5 and Figure 6 As shown, this embodiment further provides a gas distribution pipe assembly 1 , which includes a pipe body 20 and the above-mentioned nozzle assembly 10 , and the nozzle assembly 10 is detachably connected to the nozzle mounting hole 21 on the pipe body 20 .

[0077] This embodiment also provides a gas water heater, which includes the above-mentioned gas distribution pipe assembly 1.

[0078] This embodiment can adjust the gas flow rate entering the main channel 111 from the side channel 114 by setting the overall structure of the nozzle assembly 10, so that the gas flow rate can be changed during summer use, thereby avoiding the situation where the water outlet temperature of the gas water heater is too high.
