Description

Technical Field

[0001] This utility model relates to the field of domestic water pump technology, and more specifically, to a backpack-type domestic water pump. Background Technology

[0002] Traditional backpack-style liquid pumps typically employ a mechanical pump body structure, using manual or electric drive to deliver liquids. These pumps come into direct contact with the user's back, putting pressure on the lower back and potentially damaging the spine. Furthermore, spilled liquid can stain the user's clothing, resulting in a poor user experience and making them inconvenient to carry and use for extended periods.

[0003] Patent CN111790537B discloses a backpack sprayer, comprising a base, a liquid storage cylinder mounted on the base, a spray pipe and a pressure pump mounted on the liquid storage cylinder, and a linkage mechanism for driving the pressure pump. A pair of rotating shafts are vertically mounted on the bottom wall of the liquid storage cylinder, rotatably connected to the bottom wall of the cylinder. A stirring wheel is mounted on the rotating shaft, and a drive mechanism for rotating the shaft is located within the base. This invention has the following advantages and effects: by incorporating the stirring wheel, the pesticide solution is stirred in real time during spraying, ensuring thorough mixing of the pesticide and water, preventing pesticide sedimentation, and thus guaranteeing the insecticidal efficacy of the solution.

[0004] Although the above-mentioned technical solutions have modified and upgraded the internal structure of the sprayer through a series of structural components, the structure is complex and the cost is relatively high. Moreover, the complex structure increases the weight of the sprayer, which invisibly increases the pressure on the user's waist and the risk of sprains, resulting in a poor user experience. In addition, the sprayer is sometimes used to spray pesticides, and the technical solutions do not provide a specific solution for the spillage of pesticide liquid. In view of this, we propose an effective and feasible solution to address the above shortcomings, namely a backpack-type domestic water pump. Utility Model Content

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1-4 A backpack-type domestic pump includes a spray tank assembly 1, which includes a spray tank body 11. The top surface of the spray tank body 11, away from the pressure pump 4, is provided with a liquid inlet 12 to ensure that the spray tank body 11 can be replenished with liquid and to ensure its normal operation. A handle 13 is provided in the center of the top surface of the spray tank body 11 for easy handling. A back support mechanism 2 is provided on the back of the spray tank body 11. The back support mechanism 2 includes a mounting plate 21 fixedly installed on the back of the spray tank body 11. A back support component 22 is provided on the back of the mounting plate 21 to protect the user's waist from injury.

[0029] Specifically, the back support component 22 includes several cushioning springs 222 that are fixedly connected to the back of the mounting plate 21 and distributed in a matrix. When the user carries the spray tank body 11 filled with liquid, the cushioning springs 222 can reduce the pressure of the spray tank body 11 on the user's waist, thereby protecting the user's waist. The ends of several cushioning springs 222 that are away from the mounting plate 21 are connected to the same back support plate 221. The back of the back support plate 221 is shaped to fit the structure of the human back. The back support plate 221 has several through holes. The purpose of this design is to help with perspiration and provide the user with a more comfortable physical experience.

[0030] Furthermore, the front of the mounting plate 21 is fixedly connected to the back of the spray box body 11 by a number of matrix-distributed mounting blocks 25. The mounting blocks 25 can distribute the tension generated by the two shoulder straps 23 on the spray box body 11, thus extending the service life of the spray box body 11. At the same time, the mounting blocks 25 leave a gap between the spray box body 11 and the back support plate 221. This design can effectively prevent the liquid in the spray box body 11 from soiling the shoulder straps 23 and the user's clothes when it is spilled, making the design of this embodiment more humane. Two shoulder straps 23 are symmetrically provided on the left and right edges of the back of the mounting plate 21. A pressure-reducing pad 24 is provided on the upper part of the side of the shoulder strap 23 near the mounting plate 21. The pressure-reducing pad 24 can reduce the pressure and pain on the user's shoulders caused by the weight of the spray box body 11.

[0031] It needs to be further emphasized that the bottom of the spray box body 11 is provided with a base assembly 3. The base assembly 3 includes a boss 31 that is adapted to the bottom surface size of the spray box body 11 and is fixedly connected to it. Two support plates 36 are symmetrically provided on the left and right sides of the bottom surface of the boss 31. The height of the support plates 36 is greater than or equal to the height of the liquid collection tank 35, ensuring that the spray box body 11 can be placed stably. The lower end of the vertical outer wall of the boss 31 is integrally formed with a liquid receiving groove 32 with a vertical cross section of L. A liquid collection port 33 that runs vertically through the bottom is provided in the center of the front side bottom of the liquid receiving groove 32. The reason for setting the liquid collection port 33 is... This position is because when the user carries the spray tank body 11, the carrying strap 23 has a certain tensile strength, and the spray tank body 11 will tilt slightly backward under the action of gravity. This design is conducive to the collection of liquid. The bottom of the liquid outlet 33 is connected to the liquid collection tank 35 installed at the bottom of the liquid receiving groove 32 through the liquid collection pipe 34. When the liquid is spilled from the spray tank body 11, the liquid receiving groove 32 will intercept the liquid, and the overflowing liquid will gather at the liquid outlet 33, then flow into the liquid collection pipe 34 and finally into the liquid collection tank 35. This can effectively prevent the overflowing liquid from contaminating the user's clothes.

[0032] In this embodiment, a pressure pump 4 is provided at one end of the top surface of the spray box body 11, which is connected to the inside of the pressure pump 4. A spray pipe 5 is inserted into the pressure pump 4. The spray pipe 5 includes a flexible hose that is connected to the inside of the spray box body 11. The flexible hose facilitates spraying in different directions and angles, making the operation more flexible. A rigid pipe is connected to the end of the flexible hose away from the spray box body 11. The rigid pipe can control the spraying direction and duration. A spray nozzle 51 is connected to the free end of the rigid pipe. The trumpet-shaped spray nozzle 51 has a wider spraying range.

[0033] In this embodiment, a drive assembly 6 for driving the pressure pump 4 is provided on one side of the spray box body 11. The drive assembly 6 includes a connecting rod 61 with its top end slidably connected to the pressure pump 4 and a pressure rod 62 hinged to the vertical side wall at the lower end of the spray box body 11. The end of the connecting rod 61 near the hinge is hinged to the lower end of the pressure rod 62, providing power energy for the operation of this embodiment and ensuring that it can work normally.

[0034] Working principle: When using this embodiment, it can be placed on a table or cutting board at a certain height. Open the cover on the liquid inlet 12 and fill the spray tank body 11 with the specified liquid. The user puts their shoulders into the two shoulder straps 23 and then carries the spray tank body 11 on their back. At this time, under the action of the buffer spring 222, the pressure of the spray tank body 11 on the user's waist can be reduced, thereby protecting the user's waist from injury. Then, the user presses the lever 62 up and down repeatedly. The movement of the lever 62 drives the connecting rod 61 to move up and down, thereby driving the pressure pump 4 to work, so that the liquid is sprayed out from the spray nozzle 51, realizing the normal operation of this embodiment. When the liquid inside the spray tank body 11 overflows, the liquid receiving tank 32 will intercept the liquid. The overflowing liquid will collect at the liquid collection port 33, then flow into the liquid collection pipe 34 and finally into the liquid collection tank 35, which can effectively avoid the overflowing liquid from contaminating the user's clothes.

[0035] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
