Description

Technical Field

[0001] This utility model belongs to the technical field of atomizing spraying equipment, and in particular relates to an inverted spraying device for a spray pump. Background Technology

[0002] Traditional spray pumps mostly use a single valve body with a suction tube structure. When upright, they can effectively pump liquid through gravity. However, they have obvious defects when inverted or flat: when inverted, the suction tube detaches from the liquid surface, making it impossible to pump liquid. When flat, the valve body orientation can easily cause air to be sucked in, interrupting the spray. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a spray pump inverted spray device. Through the vertical downward and oblique upward double valve opening and closing structure connected to the spray pump liquid extraction pipe, it can realize liquid extraction and spraying in upright, inverted and special flat states.

[0004] Technical solution: To achieve the above objectives, this utility model provides a spray pump inverted spraying device, comprising a spray pump, a liquid extraction pipe, and a liquid extraction valve. The liquid extraction valve includes a main valve and a secondary valve connected to the liquid extraction pipe of the spray pump. The main valve is parallel to the central axis of the liquid extraction pipe and is vertically downward, while the secondary valve is at an angle to the central axis of the liquid extraction pipe and is obliquely upward. In both upright and inverted liquid extraction states, the liquid extraction valve located at the bottom and facing downward opens to allow liquid inflow, while the liquid extraction valve located at the top and facing upward closes to seal the liquid.

[0005] Furthermore, in the upright pumping state, the main valve, located in the lower position and facing downwards, opens to pump liquid, while the auxiliary valve, located in the upper position and facing upwards, closes to seal liquid.

[0006] Furthermore, in the inverted pumping state, the main valve, which is in the upper position and facing upwards, closes to seal the liquid, while the secondary valve, which is in the upper position and facing upwards, opens to pump the liquid.

[0007] Furthermore, in the horizontal pumping state, at least one inlet-immersed pumping valve is opened to pump liquid, the nozzle of the spray pump faces downward, and the direction of the nozzle is consistent with the direction of the auxiliary valve.

[0008] Furthermore, in the horizontal pumping state, when the auxiliary valve is facing down and the liquid level is higher than the main valve, both the main valve and the auxiliary valve open for pumping; when the auxiliary valve is facing down and the liquid level is lower than the main valve but higher than the inlet of the auxiliary valve, the main valve closes to seal the liquid, and the auxiliary valve opens to pump.

[0009] Furthermore, it also includes a tee; the spray pump is connected to the outlet of the tee; the main valve and the auxiliary valve are respectively connected to the two inlets of the tee, and the main valve is connected to a suction tube extending to the bottom of the spray bottle; the main valve includes a main plug and a main ball valve, the auxiliary valve includes an auxiliary plug and an auxiliary ball valve, the tee has a cavity and a small hole inside, the small hole is connected to the outlet channel of the tee through the cavity; the cavity inlet is provided with a main tee conical surface, the small hole inlet is provided with an auxiliary tee conical surface, the main plug has a main plug conical surface, and the auxiliary plug has an auxiliary plug conical surface.

[0010] Furthermore, in the upright liquid pumping state, the auxiliary ball valve is in sealing contact with the auxiliary three-way conical surface under the action of negative pressure and gravity, preventing air from entering the cavity. The main ball valve moves upward under the action of negative pressure and forms a main gap with the main end cap conical surface, and the liquid enters the cavity through the pipette and the main gap.

[0011] Furthermore, in the inverted pumping state, the main ball valve is in sealing contact with the main three-way conical surface under the action of gravity and negative pressure, and the auxiliary ball valve moves upward under the action of negative pressure to form a secondary gap with the auxiliary end cap conical surface. The liquid enters the cavity through the auxiliary end cap, the secondary gap, and the small hole.

[0012] Furthermore, the inner walls of the main end cap and the auxiliary end cap are respectively provided with grooves arranged in a circumferential array to reduce the resistance to liquid flow.

[0013] Beneficial effects: This utility model adopts a dual-valve asymmetrical structure design with the main valve vertically downward and the auxiliary valve obliquely upward. It utilizes gravity and negative pressure to automatically control the opening and closing of the valves, achieving reliable liquid pumping in three states: upright, inverted, and horizontal, thereby improving the convenience and experience of spraying.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, an inverted spraying device with a spray pump includes a spray pump 2, a liquid extraction pipe 5, and a liquid extraction valve. The liquid extraction valve includes a main valve 3 and a secondary valve 4 connected to the liquid extraction pipe 5 of the spray pump 2. The main valve 3 is parallel to the central axis of the liquid extraction pipe 5 and vertically downward, while the secondary valve 4 is at an angle to the central axis of the liquid extraction pipe 5 and obliquely upward. In both upright and inverted liquid extraction states, the lower liquid extraction valve opens to allow liquid inflow, while the upper liquid extraction valve closes to seal the liquid. This invention utilizes a dual-valve asymmetrical structure design with the main valve 3 vertically downward and the secondary valve 4 obliquely upward, automatically controlling the valve opening and closing using gravity and negative pressure to achieve reliable liquid extraction in upright, inverted, and horizontal states, improving the convenience and experience of spraying. It should be noted that during spraying, for ease of use, the inverted and horizontal spraying positions are generally used by the user, while the upright spraying position is generally used by others to spray themselves. This inverted spraying device with a spray pump has a wide range of applications, such as mosquito repellent spraying.

[0023] like Figure 2 and Figure 3 As shown, this utility model also includes a three-way valve 1; the spray pump 2 is connected to the outlet of the three-way valve 1; the main valve 3 and the auxiliary valve 4 are respectively connected to the two inlets of the three-way valve 1, and the main valve 3 is connected to a suction tube 7 extending to the bottom of the spray bottle 6; the main valve 3 includes a main plug 31 and a main ball valve 32, the auxiliary valve 4 includes an auxiliary plug 41 and an auxiliary ball valve 42, the three-way valve 1 is provided with a cavity 11 and a small hole 12 inside, the small hole 12 is connected to the outlet channel 13 of the three-way valve 1 through the cavity 11; a main three-way conical surface 14 is provided at the inlet of the cavity 11, an auxiliary three-way conical surface 15 is provided at the inlet of the small hole 12, a main plug conical surface 16 is provided inside the main plug 31, and an auxiliary plug conical surface 17 is provided inside the auxiliary plug 41. The main ball valve 32 performs opening and closing actions through lifting and lowering movements to achieve the opening and closing of the main liquid outlet channel composed of the main plug 31, the cavity 11, and the liquid outlet channel 13; the auxiliary ball valve 42 performs opening and closing actions through lifting and lowering movements to achieve the opening and closing of the auxiliary liquid outlet channel composed of the auxiliary plug 41, the small hole 12, the cavity 11, and the liquid outlet channel 13.

[0024] like Figure 2 As shown, the included angle α is an acute angle. In order to avoid insufficient sealing contact when the ball valve is closed due to an excessively large angle, and to avoid the problem of limiting the liquid flow due to an excessively small angle, the included angle α of this utility model is preferably 25°, which provides sufficient flow cross-sectional area while ensuring sealing performance.

[0025] In the upright, non-pumping state, when the spray pump 2 is not pressed by external force, both the main valve 3 and the auxiliary valve 4 are closed to seal the liquid. For example... Figure 2 As shown, in the upright, non-liquid-drawing state, the main ball valve 32 is in sealing contact with the main three-way conical surface 14 under the action of gravity, and the auxiliary ball valve 42 is in sealing contact with the auxiliary three-way conical surface 15 under the action of gravity.

[0026] like Figure 2 and Figure 3 As shown, in the upright pumping state, the main valve 3, located at the bottom and facing downwards, opens to pump liquid, while the auxiliary valve 4, located at the top and facing upwards, closes to seal the liquid. More specifically, in the upright pumping state, the auxiliary ball valve 42, under the action of negative pressure and gravity, makes sealing contact with the auxiliary three-way conical surface 15, preventing air from entering the cavity 11. The main ball valve 32, under the action of negative pressure, moves upwards to form a main gap 18 with the main end conical surface 16, and the liquid enters the cavity 11 through the pipette 7 and the main gap 18.

[0027] like Figure 2 and Figure 3 As shown, in the inverted pumping state, the main valve 3, located in the upper position and facing upwards, closes to seal the liquid, while the auxiliary valve 4, also located in the upper position and facing upwards, opens to pump liquid. More specifically, in the inverted pumping state, the main ball valve 32, under the influence of gravity and negative pressure, makes sealing contact with the main three-way conical surface 14. The auxiliary ball valve 42, under the influence of negative pressure, moves upwards and forms a secondary gap 19 with the secondary end cap conical surface 17. Liquid enters the cavity 11 through the secondary end cap 41, the secondary gap 19, and the small hole 12.

[0028] like Figure 5 As shown, in the horizontal liquid extraction state, at least one inlet-immersed extraction valve is activated to extract liquid. The nozzle 2a of the spray pump 2 faces downwards, and the orientation of the nozzle 2a is consistent with that of the auxiliary valve 4, ensuring normal execution of the liquid extraction spray. This spraying method is an extreme special case where the spray bottle 6 is in a completely horizontal position. Moreover, the nozzle 2a of the mist pump 2 sprays downwards. The upward orientation of the nozzle 2a of the mist pump 2 is not discussed in this utility model. Under the above premise, in the horizontal liquid extraction state, the horizontal liquid extraction can be further divided into the following two situations:

[0029] In the first scenario: when the secondary valve 4 is facing downwards and the liquid level is higher than that of the main valve 3, both the main valve 3 and the secondary valve 4 are opened to pump liquid. Specifically, for the main valve 3, its main ball valve 32 moves from the main end cap cone 16 to the main three-way cone 14 under negative pressure, and the liquid enters the cavity 11 through the suction pipe 7 and the main end cap 31. At the same time, the secondary ball valve 42 moves upwards under negative pressure and disengages from the secondary end cap cone 17, releasing the seal. The liquid enters the cavity 11 through the secondary end cap 41 and the small hole 12.

[0030] The second scenario: Corresponding Figure 5 ,like Figure 5As shown, when the secondary valve 4 is facing downwards and the liquid level is lower than the main valve 3 but higher than the inlet of the secondary valve 4, the main valve 3 closes to seal the liquid, and the secondary valve 4 opens to pump the liquid. For the main valve 3, since the suction tube 7 connected to the main nozzle 31 is connected to the air in the spray bottle 6, the liquid has little effect on the movement of the main ball valve 32. The main ball valve 32 moves from the main nozzle cone surface 16 to the main three-way cone surface 14 under the action of negative pressure, and the movement speed is relatively fast. The main ball valve 32 is in sealing contact with the main three-way cone surface 14. For the secondary valve 4, its secondary ball valve 42 moves upwards and separates from the secondary nozzle cone surface 17 under the action of negative pressure, releasing the seal. The liquid enters the cavity 11 through the secondary nozzle 41 and the small hole 12.

[0031] It should be noted that, precisely because the secondary valve 4 of this invention is tilted downwards rather than completely vertically downwards in the horizontal liquid pumping state, the negative pressure overcomes gravity, making the secondary ball valve 42 move more easily upwards at an angle, achieving a faster and more stable valve opening action, ensuring the effective execution of the horizontal spray and having sufficient spray volume.

[0032] like Figure 6 and Figure 7 As shown, the inner walls of the main nozzle 31 and the auxiliary nozzle 41 are respectively provided with grooves arranged in a circumferential array to reduce liquid flow resistance. The inner wall of the main nozzle 31 has a main groove 8 arranged in a circumferential array, and the inner wall of the auxiliary nozzle 41 has a secondary groove 9 arranged in a circumferential array, which facilitates smoother liquid flow through the ball valve when the valve is opened for liquid extraction.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
