Description

Technical Field

[0001] The utility model belongs to the technical field of spray devices, in particular to an automatic decontamination spray head. Background Art

[0002] In multiple sanitation operations, such as garbage transfer and compression and landfills, there are unorganized odor emissions, requiring a plant-based / microbial deodorant spray system for deodorization. This is primarily achieved through a spray mist wall, which typically consists of a water pump, pipes, and high-pressure atomizing nozzles mounted and spaced apart on the pipes. Because most biological deodorants are not homogeneous systems and have complex compositions, including both biological and non-biological materials, they often clog the spray nozzles.

[0003] Traditional high-pressure atomizing nozzles have a simple structure and do not have a pollution removal function. Frequent replacement of new nozzles can easily lead to a large amount of resource and cost waste. Some use a filter mesh inside the nozzle, but its main function is to filter particulate impurities. It has poor ability to remove microorganisms and organic matter that clog the nozzle. In addition, for nozzles with smaller structures, the manufacturing process is more difficult. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide an automatic decontamination nozzle. When the liquid enters the nozzle from the liquid inlet and passes through the second delivery chamber, the liquid acts on the ejector pin, causing the ejector pin to pass through the liquid outlet on the lower shell, automatically removing microorganisms and organic matter that are blocking the nozzle.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] An automatic decontamination nozzle includes an upper shell and a lower shell, the top of the upper shell is provided with a liquid inlet, and the upper shell has a first delivery chamber and a second delivery chamber that are connected to each other, the bottom of the lower shell is provided with a liquid outlet, and the inner wall of the lower shell is also provided with a step portion, the bottom of the upper shell has a blocking portion extending into the lower shell, the blocking portion is in contact with the inner wall of the step portion to form a third delivery chamber, the upper shell and the lower shell are connected together by a first elastic member, the blocking portion is located on the inner side of the first elastic member, and a ejector pin corresponding to the position of the liquid outlet is installed in the second delivery chamber, and the ejector pin can pass through the liquid outlet when liquid enters the second delivery chamber.

[0007] In one embodiment, the diameter of the first delivery cavity is larger than the diameter of the second delivery cavity. Through this embodiment, the liquid is pressurized when entering the second delivery cavity, ensuring that the ejector pin can pass through the liquid outlet and pressurize the liquid.

[0008] In one embodiment, the ejector includes a rod having a pointed portion at one end of the rod near the liquid outlet and a force-bearing portion at the other end, the force-bearing portion being connected to a second elastic member, and an end of the second elastic member remote from the force-bearing portion being connected to the second delivery chamber. When no liquid is supplied, the pointed portion of the ejector is located in the third delivery chamber. When liquid enters the second delivery chamber, the pointed portion of the ejector passes through the liquid outlet. When liquid enters the third delivery chamber, the pointed portion of the ejector retracts into the third delivery chamber. According to this embodiment, liquid entering the nozzle acts on the force-bearing portion as it passes through the second delivery chamber, causing the ejector connected to the force-bearing portion to move downward and pass through the liquid outlet, thereby removing microorganisms and organic matter that are clogged at the nozzle. When the liquid enters the third delivery chamber, the liquid acts on the lower housing, causing the lower housing to move away from the upper housing, and causing its displacement to exceed that of the ejector, causing the ejector to retract into the third delivery chamber, allowing the liquid to be sprayed out of the nozzle after decontamination.

[0009] In one embodiment, the diameter of the rod body matches the caliber of the liquid outlet. Through this embodiment, before the liquid is sprayed out of the nozzle, the ejector pin can be retracted into the third delivery chamber, and when the ejector pin passes through the liquid outlet, its ability to remove dirt from the liquid outlet is improved.

[0010] In one embodiment, a third elastic member is further installed in the first conveying chamber, and the top of the third elastic member is connected to a liquid-blocking member that completely covers the liquid inlet, and the bottom of the third elastic member is connected to the top of the second conveying chamber. Through this embodiment, the third elastic member presses the liquid-blocking member against the liquid outlet. When liquid enters, a gap is generated between the liquid-blocking member and the liquid inlet due to force, allowing liquid to flow in while preventing particulate impurities from entering the upper shell. The liquid-blocking member and the third elastic member can also pressurize the liquid. At the same time, after the liquid supply is stopped, the liquid-blocking member can also prevent dripping.

[0011] In one embodiment, one end of the liquid-blocking member close to the liquid inlet is an arc-shaped structure. Through this embodiment, the contact area between the liquid-blocking member and the liquid inlet is increased, thereby improving the effect of preventing granular impurities from entering the upper shell.

[0012] In one embodiment, a swirl core is further provided in the third delivery chamber. The swirl core is sleeved on the ejector pin and connected to the blocking portion. According to this embodiment, the swirl core provided in the third delivery chamber guides the liquid so that the liquid is pressurized and ejected through the liquid outlet, thereby ensuring the liquid discharge effect.

[0013] In one embodiment, the first elastic member, the second elastic member, and the third elastic member are all springs.

[0014] In one embodiment, the upper shell includes a cylinder and a connecting piece, the connecting piece is threadedly connected to the inner wall of the cylinder, the hollow portion of the connecting piece forms the second conveying cavity, and the bottom of the connecting piece is connected to the blocking portion. Through this embodiment, the connecting piece and the cylinder are threadedly connected to form the upper shell, and form a first conveying cavity and a second conveying cavity that are interconnected. At the same time, it is convenient to set a liquid-blocking piece and a third elastic piece in the first conveying cavity, and the third elastic piece is limited by the connecting piece.

[0015] The beneficial effects of the present invention are:

[0016] (1) When the liquid enters the nozzle from the liquid inlet and passes through the second delivery chamber, the liquid acts on the ejector pin, causing the ejector pin to pass through the liquid outlet on the lower shell, thereby automatically removing microorganisms and organic matter that are blocking the nozzle;

[0017] (2) When the liquid enters the third delivery chamber, it acts on the lower shell, causing the lower shell to move away from the upper shell, and its displacement exceeds the displacement of the ejector pin, causing the ejector pin to retract into the third delivery chamber, so that the liquid can be ejected from the nozzle after decontamination. The ejector pin can be set to match the size of the liquid outlet to ensure the decontamination effect;

[0018] (3) The third elastic member and the liquid-blocking member provided in the first delivery chamber, the tube diameter reduction provided in the second delivery chamber, and the swirl core provided in the third delivery chamber can all pressurize the liquid to ensure the liquid discharge effect of the nozzle.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] The utility model provides an automatic decontamination nozzle, such as Figure 1 As shown, it includes an upper shell 1 and a lower shell 2. A liquid inlet 5 is provided at the top of the upper shell 1, and a first delivery chamber 3 and a second delivery chamber 4 are connected to each other in the upper shell 1. A liquid outlet 6 is provided at the bottom of the lower shell 2. A step portion is also provided on the inner wall of the lower shell 2. The bottom of the upper shell 1 has a blocking portion 8 extending into the lower shell 2. The blocking portion 8 is in contact with the inner wall of the step portion to form a third delivery chamber 13. The upper shell 1 and the lower shell 2 are connected together by a first elastic member 7. The blocking portion 8 is located on the inner side of the first elastic member 7. A ejector pin 10 corresponding to the position of the liquid outlet 6 is installed in the second delivery chamber 4. The ejector pin 10 can pass through the liquid outlet 6 when the liquid enters the second delivery chamber 4.

[0028] It should be noted that since most biological deodorants are not homogeneous systems and their components are complex, including biological and non-biological materials, when biological deodorants pass through the spray nozzles, they often cause nozzle blockage problems, such as Figure 1 As shown, after the liquid enters the nozzle from the liquid inlet 5, the liquid acts on the ejector pin 10 when passing through the second delivery chamber 4, causing the ejector pin 10 to pass through the liquid outlet 6 on the lower shell 2, automatically removing microorganisms and organic matter that are blocking the nozzle, and automatically decontaminating the nozzle;

[0029] In one embodiment, the ejector pin 10 includes a rod body 1001, wherein one end of the rod body 1001 close to the liquid outlet 6 is a pointed portion 1002, and the other end is connected to a force-bearing portion 1003, which is connected to a second elastic member 9. The end of the second elastic member 9 away from the force-bearing portion 1003 is connected to the second delivery chamber 4. When no liquid is supplied, the pointed portion 1002 of the ejector pin 10 is located in the third delivery chamber 13. When liquid enters the second delivery chamber 4, the pointed portion 1002 of the ejector pin 10 passes through the liquid outlet 6. When liquid enters the third delivery chamber 13, the pointed portion 1002 of the ejector pin 10 retracts into the third delivery chamber 13. The diameter of the rod body 1001 matches the caliber of the liquid outlet 6.

[0030] It should be noted that if Figure 1 and Figure 2As shown, the liquid entering the nozzle acts on the force-bearing portion 1003 when passing through the second delivery chamber 4, causing the ejector pin 10 connected to the force-bearing portion 1003 to move downward and pass through the liquid outlet 6, thereby removing microorganisms and organic matter that are blocked at the nozzle. When the liquid enters the third delivery chamber 13, it acts on the lower shell 2, causing the lower shell 2 to move away from the upper shell 1, and causing its displacement to exceed that of the ejector pin 10. Even if the ejector pin 10 is retracted into the third delivery chamber 13, the liquid can be ejected from the nozzle after decontamination. The liquid outlet 6 is decontaminated by the rod body 1001 that matches the caliber of the liquid outlet 6, thereby ensuring its decontamination effect. At the same time, when the liquid reaches the liquid outlet 6, the rod body 1001 is retracted into the third delivery chamber 13, thereby improving the decontamination effect without affecting the liquid discharge from the nozzle.

[0031] Specifically, for the ejector pin, when no liquid is supplied, G 顶针 =F 拉1 =k1x1;

[0032] After the liquid is supplied, the ejector pin 10 moves to a balanced state under the action of the water pressure, and its displacement distance is Δx1;

[0033] That is, the force analysis after liquid supply is:

[0034] G 顶针 +F 水压1 =F 拉2 =k1x2;

[0035] That is: k1x2-k1x1=F 水压1

[0036]

[0037] Wherein, k1 is the elastic coefficient of the second elastic member 9, F 水居1 is the pressure exerted on the ejector pin 10 when the liquid enters the second delivery chamber 4;

[0038] Similarly, for the lower shell 2, its displacement after liquid supply is

[0039] Among them, F 水压2 is the pressure exerted on the lower housing 2 when the liquid enters the third delivery chamber 13, and k2 is the elastic coefficient of the first elastic member 7;

[0040] Friction and buoyancy are not considered here for the time being, as both are affected by the specific materials used. If the pressure change between the liquid passing through the second delivery chamber 4 and reaching the third delivery chamber 13 is not large, then in order to ensure that the displacement of the lower shell 2 is greater than the displacement of the ejector pin 10, the elastic coefficient of the first elastic member 7 can be set to be smaller than the elastic coefficient of the second elastic member 9, so that the deformation of the first elastic member 7 connecting the upper shell 1 and the lower shell 2 is greater than the deformation of the second elastic member 9.

[0041] It should be understood by those skilled in the art that, during the specific production process, the dimensions and shapes involved may vary due to different production requirements. When designing specific parameters, the design can be based on the actual conditions of each component to ensure that when no liquid is supplied, the pointed portion 1002 of the ejector pin 10 is located in the third delivery chamber 13; when liquid enters the second delivery chamber 4, the pointed portion 1002 of the ejector pin 10 passes through the liquid outlet 6; when liquid enters the third delivery chamber 13, the pointed portion 1002 of the ejector pin 10 retracts into the third delivery chamber 13. The diameter of the rod body 1001 matches the caliber of the liquid outlet 6, thereby achieving the automatic decontamination function and ensuring the decontamination effect.

[0042] In one embodiment, Figure 1 As shown, a third elastic member 11 is further installed in the first conveying chamber 3, and the top of the third elastic member 11 is connected to a liquid-blocking member 12 that completely covers the liquid inlet 5, and the bottom of the third elastic member 11 is connected to the top of the second conveying chamber 4, that is, the third elastic member 11 presses the liquid-blocking member 12 against the liquid outlet 6. When liquid enters, a gap is generated between the liquid-blocking member 12 and the liquid inlet 5 under force, allowing liquid to flow in while preventing particulate impurities from entering the upper shell 1. The liquid-blocking member 12 and the third elastic member 11 can also pressurize the liquid. At the same time, after the liquid supply is stopped, the liquid-blocking member can also prevent dripping.

[0043] Specifically, one end of the liquid-blocking member 12 close to the liquid inlet 5 is an arc-shaped structure, which can increase the contact area between the liquid-blocking member 12 and the liquid inlet 5, thereby improving the effect of preventing particulate impurities from entering the upper housing 1;

[0044] In one embodiment, a swirl core is further provided in the third delivery chamber 13. The swirl core is sleeved on the ejector pin 10 and connected to the blocking portion 8. That is, the swirl core provided in the third delivery chamber 13 guides the liquid so that the liquid is centrifugally pressurized and ejected through the liquid outlet 6, thereby ensuring the liquid discharge effect.

[0045] In one embodiment, the first elastic member 7, the second elastic member 9 and the third elastic member 11 are all springs, that is, the springs, the ejector pin 10 and the rotary core and other accessories are all used to realize the automatic decontamination of the high-pressure nozzle and ensure the decontamination effect;

[0046] In one embodiment, Figure 1As shown, the upper shell includes a cylinder and a connecting piece, the connecting piece is threadedly connected to the inner wall of the cylinder, the hollow part of the connecting piece forms the second conveying cavity, and the bottom of the connecting piece is connected to the blocking part, that is, the connecting piece is screwed into the bottom of the cylinder by means of a threaded connection to form the upper shell, and form a first conveying cavity and a second conveying cavity that are interconnected. Before the connecting piece is screwed in, it is convenient to set a liquid blocking piece and a third elastic piece in the first conveying cavity, and the third elastic piece is limited by the connecting piece, which is also convenient for subsequent disassembly and maintenance.
