Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to an outdoor water heater with multiple gas tanks. Background Technology

[0002] Existing outdoor water heaters typically only connect to a single gas tank. If the water heater's load (i.e., power) is designed to be high, it needs to burn more gas per unit time to generate sufficient heat. When gas consumption increases, the gas in the tank is consumed more quickly, leading to frequent tank replacements. Frequent tank replacements can be inconvenient and troublesome for users. Utility Model Content

[0003] In order to overcome at least one of the defects described in the prior art, the present invention provides an outdoor water heater with multiple gas tanks, which can be connected to at least three gas tanks at the same time, thereby reducing the frequency of gas tank replacement.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] An outdoor water heater with multiple gas tanks includes: a water heater body, a connector, and gas tanks. The water heater body has an air inlet, the connector has an air guiding channel, the air guiding channel has an outlet and at least three inlets, the gas tank is connected to one of the inlets, the inlet is used to guide gas flow to the air guiding channel, the outlet is connected to the air inlet and is used to guide gas out to the air inlet; each inlet is provided with a sealing member, the sealing member is sealed at the inlet and is used to move along the axial direction of the connector when force is applied to open the inlet.

[0006] Furthermore, the sealing component includes a sealing piston and an elastic component. One end of the elastic component abuts against the inner wall of the air guide channel, and the other end of the elastic component is connected to the sealing piston. The elastic component is used to provide an elastic stress to drive the sealing piston to seal at the inlet, and to drive the sealing piston to move upward along the axial direction of the connector when subjected to force.

[0007] Furthermore, the sealing component also includes a guide shaft that passes through the sealing piston; the elastic component is a spring that is fitted around the outer periphery of the guide shaft.

[0008] Furthermore, it also includes a pressure reducing valve and a gas guide pipe, the gas guide pipe having an inlet and an outlet, the inlet being connected to the pressure reducing valve, and the outlet being connected to the gas inlet; one end of the pressure reducing valve is connected to the outlet, and the other end of the pressure reducing valve is connected to the inlet; the pressure reducing valve is used to control the gas flow rate at the outlet.

[0009] Furthermore, the pressure reducing valve has a snap-fit ​​post that snaps into the inlet; the snap-fit ​​post has a first air guide hole and is used to guide airflow into the inlet after the snap-fit ​​post is snapped into the inlet.

[0010] Furthermore, the bottom of the pressure reducing valve is provided with a connector, which is inserted into the outlet; the connector has a second air guide hole, which is connected to the first air guide hole.

[0011] Furthermore, it also includes a seal, which is fitted around the outer periphery of the air duct and the inlet.

[0023] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] See Figures 1 to 4 This utility model discloses an outdoor water heater with multiple gas tanks 30, including a water heater body 10, a connector 20, and gas tanks 30. The water heater body 10 has an air inlet, and the connector 20 has an air guiding channel 21. The air guiding channel 21 has an outlet 212 and at least three inlets 211. The gas tank 30 is connected to one of the inlets 211. The inlet 211 is used to guide gas flow to the air guiding channel 21. The outlet 212 is connected to the air inlet and is used to guide gas out to the air inlet. Each inlet 211 is provided with a sealing element, which seals the inlet 211 and moves along the axial direction of the connector 20 when subjected to force to open the inlet 211.

[0027] Based on the above structure, during assembly, after connecting the outlet 212 on the connector 20 to the air inlet through a structure such as an air pipe or conduit, one or more gas canisters 30 are connected to at least three inlet ports 211 on the connector 20. When the gas canister 30 is connected to the inlet port 211, the pin on the gas canister 30 extends into the inlet port 211. At this time, the inlet port 211 is pressed by the pin on the gas canister 30. After being subjected to force, it moves along the axial direction of the connecting shaft and moves away from the inlet port 211, so that the pin on the gas canister 30 extends into the inlet port 211. Then the valve on the gas canister 30 is opened, so that the gas in the gas canister 30 is smoothly introduced into the air guide channel 21 and flows through the outlet 212 of the air guide channel 21 to the air inlet on the water heater body 10, so that the gas is introduced into the water heater body 10 through the air inlet for the water heater body 10 to heat water.

[0028] Specifically, since the connector 20 is provided with at least three inlet ports 211, when the water heater body 10 has a large power and multiple gas tanks 30 need to be connected, at least three gas tanks 30 can be connected at the same time through the at least three inlet ports 211 on the connector 20. In this way, gas can be supplied to the water heater body 10 through multiple gas tanks 30, extending the service life of the water heater and reducing the probability of replacing the gas tanks 30.

[0029] In addition, when the main body 10 of the water heater has a small power and only needs to be connected to a single gas tank 30, since the other inlets 211 are all sealed with sealing parts, the gas in the gas guide channel 21 will not leak from the other inlets 211 even if only a single gas tank 30 is connected, making it safer to use and more widely applicable.

[0030] It should be noted that the sealing component in this embodiment can be an existing elastic plunger or silicone plunger, or other structures with a certain elastic force. Thus, when the gas tank 30 is connected to the inlet 211, the connecting component (such as a pin) on the gas tank 30 is inserted into the inlet 211. At this time, the pin on the gas tank 30 presses against the sealing component, which is compressed under its own elastic stress and moves away from the inlet 211 along the axial direction of the connecting shaft, thereby opening the inlet 211 and allowing the gas inside the gas tank 30 to enter the gas guide channel 21. When the pin of the gas tank 30 is withdrawn... When the gas is discharged, the sealing component recovers its deformation under its own elastic stress and moves toward the inlet 211 to always seal the inlet 211. Therefore, even if only one of the at least three inlets 211 on the connector 20 is connected to a single gas tank 30 for use by the water heater body 10, the sealing components at the other inlets 211 that do not need to be connected to the gas tank 30 will always remain in the state of sealing the inlet 211 under its own elastic stress, so that even if only a single gas tank 30 is connected, the gas in the gas guide channel 21 will not leak from the other inlets 211.

[0031] Of course, the sealing component can also be a common plug structure. During assembly, the sealing component is connected to the inner wall of the air guide channel 21 through an elastic component 23, such as a spring, elastic column or elastic sheet. In this way, when the sealing component is subjected to force, the elastic component 23 is compressed and drives the sealing component to move axially along the connecting shaft, which can also open the inlet 211. After the force disappears, it is sealed again at the inlet 211 to achieve the above effect.

[0032] More specifically, when there are at least three inlet ports 211, there can also be at least three gas tanks 30. When the water heater has a large power and multiple gas tanks 30 need to be connected, at least three gas tanks 30 can be connected to the connectors 20 of at least three inlet ports 211 respectively, so that multiple gas tanks 30 can supply gas to the water heater body 10 at the same time, thereby increasing the heating time of the water heater body 10 and reducing the probability of frequently replacing gas tanks 30.

[0033] Preferably, the number of inlet 211 and gas tank 30 can be set to three, four, five or more, depending on the actual needs.

[0034] In addition, the water heater body 10 in this embodiment includes a heating element, which can be a gas heater. Gas is introduced into the heating element through the gas inlet for heating water.

[0035] Furthermore, the sealing component includes a sealing piston 22 and an elastic member 23. One end of the elastic member 23 abuts against the inner wall of the air guide channel 21, and the other end of the elastic member 23 is connected to the sealing piston 22. The elastic member 23 is used to provide an elastic stress to drive the sealing piston 22 to seal at the inlet 211, and to drive the sealing piston 22 to move upward along the axial direction of the connector 20 when subjected to force.

[0036] Specifically, during assembly, one end of the elastic component 23 is abutted against the inner wall of the gas guide channel 21 by welding or gluing, and the other end of the elastic component 23 can also be connected to the sealing piston 22 by welding or gluing. In this way, the sealing piston 22 can always be sealed at the inlet 211 under the elastic force of the elastic component 23. When the gas tank 30 needs to be connected to the inlet 211, the ejector pin on the gas tank 30 moves close to the inlet 211 and presses against the sealing piston 22. At this time, the elastic component 23 on the sealing piston 22 is compressed by force, causing the sealing piston 22 to move away from the inlet 211 and open the inlet 211 so that the gas inside the gas tank 30 can be introduced into the gas guide channel 21 through the inlet 211.

[0037] It should be noted that the sealing piston 22 may be an existing rubber piston, silicone piston or plastic piston, etc., while the elastic component 23 may be an existing spring or elastic column, etc.

[0038] Furthermore, the sealing component also includes a guide shaft 24, which passes through the sealing piston 22; the elastic component 23 is a spring, which is fitted around the outer periphery of the guide shaft 24.

[0039] Specifically, since the spring is fitted around the outer periphery of the guide shaft 24, when the sealing piston 22 moves to block or open the inlet 211 under the action of the elastic component 23 (spring), the guide shaft 24 restricts the sealing piston 22 to move only in a straight line along the axis, thus avoiding instability such as offset or tilt during the movement of the sealing piston 22, so that the sealing piston 22 can always block the inlet 211 according to the predetermined trajectory.

[0040] More specifically, because the guide shaft 24 ensures the linear movement of the sealing piston 22, the sealing piston 22 can fit better when it contacts the inlet 211 to seal. Thus, when the sealing piston 22 contacts the inlet 211 vertically and stably, the fit between the sealing surfaces is tighter and more uniform, reducing the sealing gap and improving the sealing effect.

[0041] Furthermore, it also includes a pressure reducing valve 40 and a gas guide pipe 50, the gas guide pipe 50 having an inlet and an outlet, the inlet being connected to the pressure reducing valve 40 and the outlet being connected to the gas inlet; one end of the pressure reducing valve 40 is connected to the outlet 212 and the other end of the pressure reducing valve 40 is connected to the inlet; the pressure reducing valve 40 is used to control the gas flow rate of the outlet 212.

[0042] Specifically, since the gas pressure inside the gas tank 30 is usually relatively high, if there is no pressure reducing valve 40, the high-pressure gas will directly enter the water heater body 10, which may damage the gas system inside the water heater body 10. Therefore, in this embodiment, a pressure reducing valve 40 and a gas guide pipe 50 are set up. The pressure reducing valve 40 is connected to the outlet 212 on the connector 20 and to the inlet of the gas guide pipe 50. This allows the gas discharged from the gas tank 30 to first pass through the pressure reducing valve 40 and then flow to the gas guide pipe 50 to be introduced into the water heater body 10. In this way, the gas pressure can be reduced to a range that the water heater body 10 can safely withstand through the pressure reducing valve 40. This can effectively avoid equipment damage and safety accidents caused by overpressure.

[0043] More specifically, the pressure reducing valve 40 has a snap-fit ​​post 41 with a first air guide hole. During assembly, after snapping the snap-fit ​​post 41 to the inlet, the first air guide hole can guide the airflow into the inlet.

[0044] Similarly, a connector 42 is provided at the bottom of the pressure reducing valve 40. The connector 42 has a second air guide hole. When the connector 42 is inserted into the outlet 212, the second air guide hole can communicate with the first air guide hole, so that the airflow from the outlet 212 can flow through the second air guide hole to the first air guide hole, then be introduced into the inlet, and finally be introduced into the water heater body 10 through the outlet of the air guide pipe 50.

[0045] Furthermore, it also includes a seal. During assembly, the seal is fitted around the outer periphery of the air duct 50 and the inlet to reduce the probability of gas leaking from the connection between the air duct 50 and the inlet.

[0046] Specifically, the sealing element can be an existing rubber sealing sleeve or silicone sealing sleeve, etc., which is used to seal the connection between the gas duct 50 and the inlet. This provides a good sealing effect, reduces the probability of gas leakage, and makes it safer to use.

[0047] Furthermore, it also includes an extension tube. During assembly, both ends of the extension tube are connected and energized to the air inlet and the connector 20, respectively. The extension tube is a flexible metal hose.

[0048] Specifically, when three or more gas cylinders 30 need to be connected in parallel with the water heater body 10, the overall connection device becomes quite large. If directly connected near the water heater body 10, it would make the area crowded and cluttered. Therefore, in this embodiment, an extension pipe is used to extend the connection length between the gas cylinders 30 and the water heater body 10. In this way, the connector 20 can be connected to multiple gas cylinders 30 and placed separately on a platform, effectively utilizing space and making the placement of the gas cylinders 30 and connector 20 more organized. For example, in outdoor camping scenarios, this allows the gas cylinders 30 to be placed centrally on a stable platform, rather than having the gas cylinders 30 and connector 20 scattered around the water heater, avoiding operational inconvenience and safety hazards caused by space congestion.

[0049] It should be noted that the extension tube can be any existing stainless steel tube or copper tube, or other metal flexible tube.

[0050] More specifically, a water tank is also provided inside the main body 10 of the water heater. By setting an inlet and an outlet in the main body 10 of the water heater, water is introduced into the water tank inside the main body 10 through the inlet, and then heated water is discharged through the outlet for user use.

[0051] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
