Description

Technical Field

[0001] The invention belongs to the technical field of bathrooms, and in particular relates to a toilet detergent supply device. Background Art

[0002] The toilet is an indispensable bathroom equipment in people's daily life. The ceramic body of the toilet needs to be cleaned frequently to keep it hygienic. At present, the cleaning of the toilet is usually done by throwing solid cleaning pills directly into the water tank. The cleaning pills dissolve to form a cleaning liquid, which is used to flush the toilet when flushing. However, the solid cleaning pills will continue to dissolve in the water tank, causing the concentration of the cleaning liquid in the water tank to increase continuously, which not only causes serious waste, but also causes corrosion to other components in the water tank.

[0003] With the progress of social science and technology, cleaning pills are gradually eliminated and replaced by prepared cleaning liquids and supporting supply equipment. For example, the existing Chinese patent: CN206457899U discloses a quantitative toilet detergent supply device, including a toilet water tank and a guide rod, a toilet water tank cover is clamped on the upper side of the toilet water tank, one end of the guide rod passes through the toilet water tank cover, and the other end of the guide rod passes into the interior of the toilet water tank, a float is slidably installed on the guide rod, nuts are threadedly installed at both ends of the guide rod, a pressure rod is arranged on one side of the float, a cross bar is arranged below the pressure rod, the upper side of the cross bar is welded to one end of a spring fixing column, the other end of the spring fixing column passes through a valve seat, a spring is sleeved on the spring fixing column, a water stop element is sleeved on the upper side of the spring fixing column, a liquid outlet pipe is welded on one side of the valve seat, a detergent storage box is welded on the upper side of the valve seat, and the detergent storage box is bonded to one side of the toilet water tank. The device uses a float and utilizes the change of water level in the water tank to drive the float to rise and fall, thereby realizing the opening and closing of the water stop element. However, the device is too large to adapt to toilet tanks of different sizes, and a toilet tank cover needs to be customized to match the fixing of its guide rod, which has high expenditure costs and strong limitations. Therefore, it is necessary to provide a detergent supply device with a small size, low expenditure cost and adaptable to toilet tanks of different sizes to solve the shortcomings of the prior art.

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0019] refer to Figure 1-3 As shown, the present invention provides a toilet detergent supply device, comprising: an upper bottle body 1 and a lower bottle body 2, wherein the upper bottle body 1 is threadedly connected to the lower bottle body 2, a liquid outlet pipe 3 and an air return pipe 4 are provided through the top of the lower bottle body 2, a first one-way valve 5 is provided at one end of the liquid outlet pipe 3 extending into the lower bottle body 2, a second one-way valve 6 is provided at one end of the air return pipe 4 extending into the upper bottle body 1, and the bottom end of the lower bottle body 2 is open. The upper bottle body 1 is closed, and detergent is stored inside; the first one-way valve 5 is used for the circulation of detergent, and its circulation direction is from the upper bottle body 1 to the lower bottle body 2; the second one-way valve 6 is used for the circulation of gas, and its circulation direction is from the lower bottle body 2 to the upper bottle body 1. Preferably, the first one-way valve 5 and the second one-way valve 6 have the same structure, are both made of silicone, and have an opening at the tip.

[0020] As a preferred embodiment, the lower bottle body 2 comprises: a cover body 7, a circular platform 8 is provided on the top of the cover body 7, a connecting portion 9 is integrally formed around the circular platform 8, an internal thread is provided on the inner wall of the connecting portion 9, and an external thread matching the internal thread of the connecting portion 9 is provided at the bottle mouth of the upper bottle body 1. Preferably, a sealing gasket is also provided between the connecting portion 9 and the upper bottle body 1.

[0021] As a preferred embodiment, the bottom end of the cover body 7 is also integrally formed with a plurality of grille bars 10, through slots 11 are formed between adjacent grille bars 10, and a counterweight 12 is slidably connected to the outer wall of the grille bar 10. Specifically, the through slot 11 is used for both water intake and drainage, and air intake and exhaust; more preferably, a positioning structure is also provided on the counterweight 12, and the relative position of the counterweight 12 and the grille bar 10 can be adjusted through the positioning structure, thereby changing the height of the through slot 11, so as to ensure that when toilet tanks of different sizes are pumped, the through slot 11 can be exposed at the lowest point of the water level.

[0022] As a preferred embodiment, the circular platform 8 is provided with a through hole adapted to the liquid outlet pipe 3 and the air return pipe 4, a sealing ring is provided in the through hole, and a bell mouth 13 is integrally formed at the end of the air return pipe 4 extending into the cover body 7. The design of the bell mouth 13 is more convenient for the device to return air, thereby maintaining the stability of the air pressure in the upper bottle body 1.

[0023] As a preferred embodiment, the bottom end of the cover body 7 is lower than the bottom ends of the liquid outlet pipe 3 and the air return pipe 4. Thus, when the water level is submerged in the through groove 11, a closed chamber is formed.

[0024] The working process and principle of the present invention are:

[0025] First, open the toilet tank cover and place the supply device vertically into the water tank. During the lowering process, when the water level is above the through groove 11, the cover body 7 and the water surface form a closed chamber. As the lowering depth increases, the liquid pressure gradually increases (P=ρ·g·h). Part of the air in the closed chamber will be squeezed into the upper bottle body 1 through the return air pipe 4, thereby maintaining a balanced state at all times. Then, under the action of the gravity of the counterweight 12, it sinks to the bottom of the water tank. During the entire lowering process, the water level in the closed chamber is always lower than the bottom of the liquid outlet pipe 3 and the return air pipe 4.

[0026] When the user flushes, the liquid level in the water tank drops rapidly, and the liquid pressure decreases accordingly. The pressure balance between the upper bottle body 1 and the lower bottle body 2 is broken, and the pressure in the upper bottle body 1 is greater than the pressure in the lower bottle body 2, thereby squeezing the cleaning liquid in the upper bottle body 1 into the lower bottle body and mixing with the water in the water tank. When the through groove 11 is exposed, the atmospheric pressure enters the cover body 7, and the outflow of the cleaning liquid stops as the upper bottle body 1 is balanced with the atmospheric pressure. Since the amount of water replenished in the water tank each time is fixed, a quantitative supply of the cleaning liquid can be achieved.

[0027] When the water tank returns water, the water level rises, and the air in the lower bottle body 2 is discharged through the through groove 11. When the water level is above the through groove 11, the cover body 7 and the water surface form a closed chamber. As the water level continues to rise, the liquid pressure gradually increases, and part of the air in the closed chamber will be squeezed into the upper bottle body 1 through the return air pipe 4, thereby maintaining a balanced state at all times. During the entire water return process, the water level in the closed chamber is always lower than the bottom of the liquid outlet pipe 3 and the return air pipe 4.

[0028] Furthermore, the minimum liquid level when pumping water from different toilet tanks is different, and it is necessary to ensure that the minimum liquid level exposes the through groove 11 to facilitate the return of air from the upper bottle body 1. Preferably, the height of the through groove 11 can be adjusted by sliding the position of the counterweight block 12 to improve the adaptability of the supply device.
