Manual ignition is required, so a convenient and reliable manual ignition mechanism needs to be installed on the gas water heater. Existing gas water heaters cannot meet the requirements.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1-7As shown, this utility model provides a piezoelectric gas water heater, including a housing 27. Inside the housing 27, from top to bottom, are sequentially installed a smoke hood 1, a heat exchanger 2, a burner 3, and a piezoelectric mechanical thermostatic water-gas linkage valve 7. A water pipe 6 is coiled around the outer side of the heat exchanger 2. A first support plate 17 connected to a back plate is installed on the lower inner side of the housing 27. An operation panel 22 is installed on the lower front side of the housing 27. A second support plate 21 arranged horizontally is connected to the inner side of the operation panel 22. The piezoelectric mechanical thermostatic water-gas linkage valve 7 is installed below the second support plate 21 and connected to the first support plate 17. A control knob connected to the piezoelectric mechanical thermostatic water-gas linkage valve 7 is installed on the operation panel 22. The second support plate 21... A third support plate 18 is installed on one side of the burner 3, which is connected to the second support plate 21 and the first support plate 17. A push-button igniter 12 is installed on the third support plate 18. The push-button igniter 12 is connected to the button 14 on the control panel 22. An ignition assembly 5 is installed on the front side of the burner 3. The ignition needle 4 in the ignition assembly 5 is electrically connected to the push-button igniter 12. By setting the first support plate 17, the second support plate 21 and the third support plate 18 inside the housing 27, the piezoelectric mechanical thermostatic water-gas linkage valve 7, the push-button igniter 12 and the control panel 22 are integrated and connected together. The components will not be loose. When the button 14 presses the push-button igniter 12 to ignite, it will not be tilted or loose, thus meeting the manual ignition requirements of the gas water heater.

[0024] Specifically, when using it, you need to press button 14 continuously to activate the push-button igniter 12, so that the ignition needle 4 emits a spark, which works with the gas sprayed from the ignition assembly 5 to ignite the burner 3. The heat exchanger 2 can heat the water flowing in the water pipe 6. One end of the water pipe 6 is connected to the piezoelectric mechanical thermostatic water-gas linkage valve 7, and the other end of the water pipe 6 is the water outlet 10, so that hot water can be output.

[0025] The ignition assembly 5 can be an ODS (Original Discharge Separator) ignition assembly. An ODS ignition assembly is a device in gas equipment used to ignite and maintain a pilot flame. It typically features automatic ignition and oxygen deficiency protection. Its principle is that gas enters the nozzle through the intake pipe and is ejected from the nozzle orifice to form a high-pressure gas flow. Simultaneously, air is drawn in through the air injection port of the combustion chamber and fully mixes with the gas. The ignition needle generates an electric spark under the action of high voltage, igniting the gas mixture and causing it to burn in the combustion chamber, forming the pilot flame.

[0026] Similarly, the piezoelectric mechanical thermostatic water-gas linkage valve 7 is connected to the burner 3 and the ignition assembly 5, which can control the output of gas, facilitating ignition and continuous gas output. Specifically, the lower end of the piezoelectric mechanical thermostatic water-gas linkage valve 7 is provided with an air inlet 11 and a water inlet 13. The front side of the piezoelectric mechanical thermostatic water-gas linkage valve 7 is provided with an air regulating shaft 9 and a water regulating shaft 8 corresponding to the air inlet 11 and the water inlet 13, respectively. The operation panel 22 is equipped with an air regulating knob 16 and a water regulating knob 15 connected to the air regulating shaft 9 and the water regulating shaft 8, respectively, integrating the regulation of gas and water into one, making operation simple.

[0027] Specifically, the first support plate 17 and the third support plate 18 are in the shape of "П", and the interior of the first support plate 17 and the third support plate 18 can be used to run pipelines or facilitate maintenance.

[0028] In this embodiment, as Figure 3-7 As shown, the rear side of the burner 3 is connected to the back plate of the housing 27 via the fourth support plate 20. The fourth support plate 20 can improve the installation strength of the burner 3. The position of the fourth support plate 20 corresponds to the position of the first support plate 17, which facilitates the installation of the fourth support plate 20 by utilizing the hollow position of the first support plate 17.

[0029] In this embodiment, as Figure 6 As shown, a side plate 26 connected to the second support plate 21 is provided on one side of the third support plate 18, and the side plate 26 can realize a firm connection between the third support plate 18 and the second support plate 21.

[0030] In this embodiment, as Figure 7 As shown, an inwardly extending annular limiting wall 24 is provided on the operation panel 22 at the position corresponding to the button 14. The button 14 is located inside the annular limiting wall 24 and can move axially along the annular limiting wall 24. The annular limiting wall 24 can limit and guide the axial movement of the button 14 to prevent the button 14 from deflecting when pressed.

[0031] Meanwhile, at least one anti-rotation limiting groove 25 is provided on the side wall of the button 14 along its axial direction, and a limiting hook plate 23 corresponding to the anti-rotation limiting groove 25 is provided at the axial end of the annular limiting wall 24. The limiting hook plate 23 extends into the anti-rotation limiting groove 25, and the limiting hook plate 23 can axially limit and prevent rotation of the button 14.

[0032] In this embodiment, as Figure 5As shown, a fifth support plate 19 for mounting and fixing the ignition assembly 5 is installed on the inner front side of the housing 27. The ignition assembly 5 can be firmly installed through the fifth support plate 19, and the relative position between it and the push-type igniter 12 will not change, ensuring a firm connection.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
