Technical Field

[0001] This utility model relates to the field of spray bottle technology, specifically to a foam spray bottle. Background Technology

[0002] A foam sprayer is a portable manual or electric spraying tool that can fully mix the liquid stored inside (such as detergent, disinfectant, pesticide, nutrient solution, etc.) with air, generate rich and fine foam through a specific foaming mechanism, and spray it onto the surface of the target object. It is widely used in many fields such as household cleaning, plant disease and pest control, pet care, and car maintenance.

[0003] However, foam sprayers require continuous manual pressing during use, which can easily lead to finger fatigue, especially when dealing with large areas, resulting in a poor user experience. Furthermore, the connection cables between the control board and various electrical components are usually in a free-suspension state, which can easily lead to wear, loosening, or short circuits during long-term use or transportation, affecting the stability and safety of the equipment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a foam sprayer to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A foam sprayer includes a sprayer, a spraying assembly connected to the top of the sprayer, and a sprayer cap threadedly connected to the top of the sprayer. A mounting groove is provided on the top of the sprayer cap, and a foam pump is installed inside the mounting groove. The foam pump has multiple delivery pipes, one end of which is connected to a spray connector, and another end of which is connected to a delivery connector. One end of the delivery connector is connected to the sprayer cap. A second delivery connector is located below the sprayer cap, with a second delivery pipe at one end that contacts the interior of the sprayer. A spray pipe is located outside the sprayer cap, with a spray head connected to one end. An auxiliary assembly is located inside the sprayer cap.

[0008] Furthermore, in order to better restrict the control board and connecting wires, the auxiliary components include multiple auxiliary plates inside the spray bottle cap. One of the auxiliary plates has an auxiliary slot and an auxiliary hole. The control board is located inside the auxiliary slot. A limiting plate is in contact with the control board. One end of the limiting plate is engaged with the inside of the auxiliary hole. The other two plates have multiple wire fixing slots. Elastic plungers are provided on both sides inside the wire fixing slots. A clamping plate is provided at one end of the elastic plunger.

[0009] Furthermore, in order to better install and secure the battery, the control board is electrically connected to the battery, and a mounting bracket is provided around the battery, which is located inside the spray bottle cap.

[0010] Furthermore, to better protect the charging connector, a charging slot is provided on one side of the spray bottle cap. The charging slot has a sealing plug inside and a charging connector is installed inside. One end of the charging connector is electrically connected to the battery.

[0011] Furthermore, in order to better dissipate the heat generated by the electrical equipment, the spray bottle cap has multiple heat dissipation vents, and the inside of the heat dissipation vents is equipped with a filter screen and a molecular sieve plate.

[0012] Furthermore, in order to better provide auxiliary shielding and protection for electrical equipment, the inside of the mounting slot is equipped with multiple mounting posts, of which four mounting posts are engaged with shielding covers one inside the mounting slot, and the other two mounting posts are engaged with shielding covers two inside the mounting slot.

[0013] Furthermore, in order to better control the foam sprayer, a control switch is provided on the second cover, and the control switch is electrically connected to the control main board.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By using the spraying component in the spray bottle, the user's hands are freed, avoiding finger fatigue caused by repeated pressing. Especially when cleaning large areas or working for a long time, the convenience and comfort of operation are significantly improved. The use of a foam pump instead of the existing air pump achieves full mixing of liquid and air, thereby producing a fine, uniform and stable foam spray, which significantly improves the coverage and adhesion of cleaning, spraying or disinfection and other usage scenarios, greatly optimizing the user experience. The auxiliary component in the spraying component can automatically adjust the clamping force according to the thickness of the connecting wire, firmly fixing each connecting wire in the wire trough, realizing orderly wiring, effectively avoiding shaking, wear and accidental detachment of the connecting wire during use, which not only reduces the risk of circuit failure and improves the reliability of equipment operation, but also facilitates later maintenance and repair.

[0016] (2) By setting a sealing plug in the charging slot, dust, moisture and other foreign objects are effectively prevented from entering, protecting the charging interface, avoiding poor contact or damage, and improving the reliability and service life of the foam sprayer. The heat dissipation vent, filter screen and molecular sieve plate set in the sprayer lid not only ensure the heat dissipation needs of the equipment during operation, but also filter out impurities in the air, absorb moisture, prevent water vapor from entering, protect the internal structure of the equipment in all aspects, reduce the risk of failure, ensure the stable operation of the foam sprayer, and greatly improve the user's operating experience.

[0026] Example 1:

[0027] like Figures 1-4As shown, a foam sprayer according to an embodiment of the present invention includes a sprayer 1, a spraying assembly 2 connected to the top of the sprayer 1, and a sprayer cap 201 threadedly connected to the top of the sprayer 1. A mounting groove is provided on the top of the sprayer cap 201, and a foam pump 202 is disposed inside the mounting groove. The foam pump 202 is provided with two delivery pipes 203, one end of which is connected to a spray connector 204, and the other end of which is connected to a delivery connector 205. One end of connector 205 is connected to the spray bottle cap 201. A second conveyor connector 206 is provided below the spray bottle cap 201. The second conveyor connector 206 communicates with the interior of the first conveyor connector 205. One end of the second conveyor connector 206 is provided with a second conveyor pipe 207. One end of the second conveyor pipe 207 contacts the interior of the spray bottle 1. A spray pipe 208 is provided on the outside of the spray bottle cap 201. The spray pipe 208 communicates with the interior of the spray connector 204. One end of the spray pipe 208 is connected to a spray head 209.

[0028] The spray bottle cap 201 has two heat dissipation vents. Inside the heat dissipation vents are filter screen plates 8 and molecular sieve plates 9, which are used to filter air impurities and moisture. The mounting groove has six mounting posts 10. Four of the mounting posts 10 are engaged with the inside of the mounting groove to form a first cover 11. The other two mounting posts 10 are engaged with a second cover 12. A sealing gasket (not shown in the figure) is provided at the junction of the second cover 12, the first cover 11 and the spray bottle cap 201 in actual use to improve the sealing performance. The second cover 12 is equipped with a control switch 13, which is electrically connected to the control main board 302.

[0029] Example 2:

[0030] like Figures 1-2 , Figure 4 , Figure 5 As shown, according to an embodiment of the present invention, a foam spray bottle has an auxiliary component 3 inside the spray bottle cap 201. The auxiliary component 3 includes three auxiliary plates 301 inside the spray bottle cap 201. One of the auxiliary plates 301 has an auxiliary groove and an auxiliary hole. A control main board 302 is provided inside the auxiliary groove. A limiting plate 303 is in contact with the control main board 302. One end of the limiting plate 303 is engaged with the inside of the auxiliary hole. The other two plates have two wire-fixing grooves for placing connecting wires. Elastic plungers 304 are provided on both sides inside the wire-fixing grooves for adaptively adjusting the clamping plate 305 according to the size of the connecting wire. One end of the elastic plunger 304 is provided with the clamping plate 305 for clamping and restricting the connecting wire.

[0031] The control board 302 is electrically connected to the battery 4. The battery 4 is provided with a fixing seat 5 on its periphery. The fixing seat 5 is located inside the spray bottle cover 201. A charging slot is provided on one side of the spray bottle cover 201. A sealing plug 6 is provided inside the charging slot to protect the charging connector 7 when it is not charging. The charging connector 7 is provided inside the charging slot. One end of the charging connector 7 is electrically connected to the battery 4.

[0032] The charging connector 7, storage battery 4, elastic plunger 304, control main board 302, control switch 13, and foam pump 202 are existing technologies and will not be described in detail (such as the PYFP528-XA (528 foam pump) produced by Pincheng Motor). The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In summary, with the help of the above-mentioned technical solution of this utility model, when the foam sprayer starts working, the device is first started by the control switch 13. The control switch 13 transmits the signal to the control main board 302. After receiving the instruction, the control main board 302 starts the foam pump 202. Then, the foam pump 202 draws liquid from the inside of the sprayer 1 through the connection between the first conveying connector 205 and the second conveying connector 206, and delivers the liquid to the inside of the foam pump 202. When the foam pump 202 is working, it draws in air, so that the liquid and air are fully mixed in the pump body to form a fine foam-like substance.

[0035] The generated foam enters the spray pipe 208 through one of the delivery pipes 203 and the spray connector 204, and is finally sprayed evenly by the spray head 209 to achieve foam coverage of the target surface. During the entire operation, the control board 302 continuously monitors the equipment's operating status and the battery 4 provides stable power support to ensure the normal operation of each electrical component. The battery 4 is installed in the fixed base 5, which effectively restricts its movement inside the spray bottle cover 201 and improves operational stability.

[0036] When the battery 4 needs to be charged, remove the sealing plug 6 in the charging slot to expose the charging connector 7 and connect it to an external power source for charging. After charging is completed, reinsert the sealing plug 6 to prevent dust and moisture from entering. The heat generated during the operation of the equipment enters through one of the heat dissipation vents on the spray bottle cover 201. The incoming gas passes through the filter screen plate 8 inside the heat dissipation vent to block external dust, while the molecular sieve plate 9 absorbs moisture from the air to prevent internal components from getting damp. After entering, the gas carrying hot gas is discharged through the other heat dissipation vent.

[0037] The control board 302 is installed in the auxiliary slot and fixed by the limiting plate 303 inserted into the auxiliary hole to improve the shock resistance. Various wires connected to the control board 302 are placed in the wire fixing slot of the auxiliary plate 301. The elastic plunger 304 pushes the clamping plate 305 to elastically clamp the wires to prevent loosening. The mounting posts 10 in the mounting slot are respectively clamped to the shielding cover 11 and shielding cover 22, which not only provide physical protection for the foam pump 202 and other internal components, but also facilitate subsequent maintenance.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
