Description

Technical Field

[0001] The utility model belongs to the technical field of bathtub detection, in particular to a bathtub performance detection device. Background Art

[0002] A bathtub is a plumbing fixture used for bathing or showering, typically found in a bathroom. After production, existing bathtubs require performance testing to ensure their longevity.

[0003] At present, when conducting a hot water resistance test on a bathtub, water needs to be added to more than 80% of the bathtub's depth. Water will evaporate during the heating process, so it is necessary to add water to the bathtub in time to ensure a constant water level inside the bathtub. After adding water to the bathtub, it is easy to cause uneven water temperature inside the bathtub, affecting the accuracy of the test data. Publication No.: CN218791966U discloses: a bathtub detection auxiliary device, which stirs the test liquid in the bathtub by setting a stirring blade to make the test liquid in the bathtub uniform in temperature. However, the stirring blade requires an additional drive component to drive it, which increases the manufacturing and use costs of the device. In addition, the position of the stirring blade is fixed. When the stirring blade rotates, it can only stir the water in the fixed position, which is easy to cause uneven mixing of hot water and cold water, affecting the accuracy of the bathtub detection data.

[0004] In response to the above problems, we propose a bathtub performance detection device. Utility Model Content

[0025] The placement table 2 facilitates the placement of the bathtub to be tested. Combined with the sliding setting of the placement table 2 and the support frame 1, it is convenient to adjust the bathtub to the detection area for detection. Under the mutual cooperation of the water pump 7, the first water inlet pipe 8, the first valve and the water outlet pipe 10, it is convenient to pump external water into the bathtub to be tested for subsequent detection. The heating rod 17 is convenient for heating the water inside the bathtub. Combined with the U-shaped frame 18, it is effectively isolated and protected for the heating rod 17 to prevent the heating rod 17 from contacting the inner wall of the bathtub and causing damage to the heating rod 17 or the bathtub. At the same time, under the joint action of the water pump 7, the second water inlet pipe 9, the second valve and the water outlet pipe 10, it is convenient to pump out the water at one end of the bathtub and inject it into the other end of the bathtub. Combined with the stirring component, the water inside the bathtub is fully mixed, ensuring the uniformity of the test water temperature inside the bathtub and ensuring the accuracy of the test data.

[0026] The stirring assembly includes a reciprocating screw 11, a shell 12, a turbofan 13, a movable block 14, a paddle 15 and a transmission assembly 16. Two strip grooves are relatively penetrated on the movable plate 6. The two reciprocating screws 11 are respectively arranged in the two strip grooves. The shell 12 is fixed to the rear side of the right end face of the movable plate 6 through a support rod. The turbofan 13 is rotatably installed inside the shell 12 through a rotating shaft. The rotating shaft is connected to the reciprocating screw 11 on the rear side. The movable block 14 is threaded on the reciprocating screw 11. The paddle 15 is fixed to the bottom of the movable block 14. The transmission assembly 16 is arranged between the two reciprocating screws 11. The shell 12 is arranged on one side of the second water inlet pipe 9, and the second water inlet pipe 9 is connected to the inner cavity of the shell 12.

[0027] A telescopic hose 19 is connected to the rear end of the first water inlet pipe 8. A support plate is fixed to the left surface of the movable plate 6. The water outlet pipe 10 passes through the support plate. A liquid level sensor 20 is installed at the bottom of the support plate to facilitate monitoring the water level inside the bathtub during the detection process so that water can be added to the bathtub in time. Temperature sensors 21 are installed on both the left and right sides of the U-shaped frame 18 to facilitate monitoring of the water inside the bathtub.

[0028] The transmission assembly 16 includes a transmission belt and a pulley. The two pulleys are respectively arranged on the two reciprocating screws 11. The transmission belt is arranged between the two pulleys. A limiting groove is opened on one side of the inner wall of the strip groove. A limiting block is slidingly arranged in the limiting groove. The limiting block is fixedly connected to the movable block 14, which effectively serves as a limiting guide for the movable block 14, thereby ensuring the stability of the movement process of the dial plate 15.

[0029] The support frame 1 is provided with a slide groove 23, and the placement platform 2 is slidably arranged in the slide groove 23. A guide rod is fixed inside the slide groove 23, and the guide rod passes through the lower part of the placement platform 2. The placement platform 2 slides with the guide rod. A hydraulic cylinder 22 is installed at the bottom of the support frame 1. The telescopic end of the hydraulic cylinder 22 is connected to the lower part of the placement platform 2, and the hydraulic cylinder 22 is used to push the placement platform 2 to move along the slide groove 23, thereby driving the bathtub placed on the placement platform 2 to move. Vertical plates 24 are fixed to the front and rear surfaces of the placement platform 2, and screws 26 are threaded on the vertical plates 24. The inner end of the screw 26 is rotatably connected to a rubber splint 25. A limit rod is slidably provided on the vertical plate 24, and the inner end of the limit rod is connected to the rubber splint 25. The screw 26 is used to adjust the mutual approach of the two rubber splints 25, and the two sides of the bathtub placed on the placement platform 2 are limited and clamped, thereby ensuring the stability of the bathtub during the inspection process.

[0030] A servo motor 27 is installed on the top of the fixed frame 3. The output shaft of the servo motor 27 is connected to the upper end of the first screw rod 4. A lifting rod is slidingly set on the fixed frame 3. The lower end of the lifting rod is fixedly connected to the L bracket 5, which effectively limits the L bracket 5 and ensures the stability of the up and down movement of the L bracket 5.

[0031] Example:

[0032] When in use, first place the bathtub to be tested on the placement table 2, and adjust the screw 26 to drive the rubber clamping plate 25 closer to the bathtub until the two rubber clamping plates 25 are clamped on both sides of the bathtub, thereby limiting and fixing the bathtub;

[0033] After the bathtub is clamped stably, the hydraulic cylinder 22 is activated to push the placement platform 2 to move along the direction of the slide 23, thereby driving the clamped bathtub to move directly below the movable plate 6;

[0034] At this time, the servo motor 27 is started, driving the first screw 4 to rotate. Under the threaded cooperation between the L bracket 5 and the first screw 4, combined with the sliding cooperation between the lifting rod and the fixed frame 3, the L bracket 5 is driven to move downward steadily, combined with the movable plate 6, until the second water inlet pipe 9, the water outlet pipe 10, the U-shaped frame 18 and the heating rod 17 are moved down to the inside of the bathtub;

[0035] Next, insert the end of the telescopic hose 19 away from the first water inlet pipe 8 into the external water tank, start the water pump 7, open the first valve, close the second valve, and pump water from the outside through the water pump 7, the first water inlet pipe 8, and the telescopic hose 19. The pumped water is then injected into the bathtub through the outlet pipe 10. The water level inside the bathtub is monitored by the liquid level sensor 20. When the water level inside the bathtub reaches the detection and use requirements, the water pump 7 and the first valve are closed.

[0036] At this time, the heating rod 17 is started to heat the water inside the bathtub, and the temperature sensor 21 is used to monitor the water temperature inside the bathtub;

[0037] During this process, the water pump 7 is started, the first valve is closed, and the second valve is opened. Water from one end of the bathtub is pumped out through the water pump 7 and the second water inlet pipe 9, and is injected into the other end of the bathtub through the water outlet pipe 10.

[0038] Water flows through the second water inlet pipe 9 and impacts the turbine fan 13, driving the rotating shaft to rotate, which in turn drives the reciprocating screw 11 on the rear side to rotate. Under the action of the transmission assembly 16, the reciprocating screw 11 on the front side rotates synchronously. Combined with the movable block 14, it drives the front and rear paddles 15 to reciprocate synchronously, stirring the water inside the bathtub, ensuring the uniformity of the water temperature inside the bathtub, and thus ensuring the accuracy of the test data.

[0039] The liquid level sensor 20 monitors the water level inside the bathtub in real time, and with the cooperation of the water pump 7, the first water inlet pipe 8, the water outlet pipe 10, the first valve and the telescopic hose 19, water is added to the bathtub in a timely manner. At the same time, the water pump 7, the second water inlet pipe 9, the second valve and the water outlet pipe 10 cooperate with each other, combined with the stirring component, to mix and stir the water inside the bathtub to ensure the uniformity of the water temperature inside the bathtub, ensure that the water inside the bathtub is heated to 80°C and maintained for 100 hours, and complete the test of the hot water resistance of the bathtub.

[0040] Compared with the prior art, the present invention pumps water out of one end of the bathtub and injects it into the other end of the bathtub through the mutual cooperation of the water pump 7, the second water inlet pipe 9, the second valve and the water outlet pipe 10. At the same time, when the water flows through the second water inlet pipe 9, it impacts the turbine fan 13, driving the rotating shaft to rotate. Combined with the transmission assembly 16, it drives the two reciprocating screws 11 to rotate synchronously, and then drives the front and rear paddles 15 to reciprocate synchronously, stirring the water inside the bathtub, ensuring the uniformity of the water temperature inside the bathtub, and thus ensuring the accuracy of the test data. This solves the problem of the prior art that the test liquid in the bathtub is stirred by the provision of a stirring blade to make the test liquid in the bathtub uniform in temperature, but the stirring blade requires a separate drive assembly to drive it, which increases the manufacturing and use costs of the device. At the same time, it solves the problem of the prior art that the position of the stirring blade is fixed. When the stirring blade rotates, it can only stir the water at a fixed position, which easily leads to uneven mixing of hot water and cold water, affecting the accuracy of the bathtub test data.

[0041] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the water pump 7, heating rod 17, liquid level sensor 20, temperature sensor 21, hydraulic cylinder 22 and servo motor 27 in the present invention are all purchased on the market, and technical personnel in this field can install and use them according to requirements.

[0042] All technical features in this embodiment can be freely combined according to actual needs.
